CloudSURVEY is a cloud-based management portal that is designed for use with Siretta’s SNYPER and SENTRY cellular network analyser products. SENTRY surveying is controlled from the CloudSURVEY portal (as it has no local interface) and SENTRY automatically uploads any surveys that it conducts to CloudSURVEY. Whereas with SNYPER, users can choose to upload their surveys to CloudSURVEY while viewing the survey file on a PC.
Utilising CloudSURVEY with a SNYPER provides certain benefits. Firstly, users can gain more detailed information about the conducted surveys. This includes, but is not limited to, insights into network dominance, survey mapping and keyword searching. Network dominance ranks networks based not only on the number of cells discovered, but their signal strength. Survey mapping shows the location of discovered cells by marking them on an interactive map. This allows users to visualise the cellular environment and apply visual overlays. Lastly, with all surveys safely stored in CloudSURVEY, surveys can be searched for, using keywords such as the location, and compared with other saved surveys. For instance, if a site has been surveyed in the past it could be compared with a recent survey to see how the cellular networks discovered may have evolved over time.
The SENTRY utilises a SIM card to connect to the cellular network. This enables it to post surveys to CloudSURVEY seamlessly and access the same benefits available to SNYPERs. Users configure SENTRY survey requirements and initiate or terminate surveys through CloudSURVEY. Surveys are automatically uploaded to CloudSURVEY as they are conducted.
An account holder of either a SENTRY or SNYPER may enable the sharing feature. Once sharing is enabled, the shared accounts can view all surveys stored on the sharer account, allowing for easy collaboration within a team or organisation.
Creating and uploading surveys to CloudSURVEY is free of charge. However, placing cell site markers on maps requires CloudSURVEY processing and hosted mapping resources. Users can purchase tokens via the CloudSURVEY portal, which are consumed when map data is generated and updated.

Cell mapping uses a Google API. Google collects information from Google Maps users about where they are and to which cell they are connected. This in turn is used to estimate the position of the cell used and stored in a database. The Google API uses this database to map discovered cells.
The advantages of this are that newly deployed cells are quickly discovered and added to Google’s database, and that the mapping system will work worldwide. The disadvantage is that the database can only map cells that a phone has registered with. For GSM, UMTS, LTE and 5G NR cells this is not a problem.
For NB-IoT and LTE-M, cell mapping is best effort and comes with no guarantees as a phone would not normally connect to these types of cell. However, often LTE-M cells are shared with LTE cells and can be indirectly found because of the sharing, but this is highly dependent on how the cell has been configured by the operator. In practice, CloudSURVEY is able to map many LTE-M cells but this capability will vary between networks and countries. Expectations that an NB-IoT cell will be mapped are very low.
Access the CloudSURVEY portal at www.cloud-survey.co.uk. Siretta uses a unified login procedure to access some areas of Siretta’s websites:
https://portal.siretta.com/
https://www.siretta-link.com/
https://www.cloud-survey.co.uk/
An account created for one of these websites will also work on the other websites. Account logins are a combination of the user’s email address as a username, and a password. If using a password manager, it is suggested that Siretta’s websites be set as equivalent domains for best management of login details.
Use a web browser and enter https://www.cloud-survey.co.uk/ to go to the CloudSURVEY website. From here, you'll need to either log in or register for a new account.
If you already have an account, enter your Username and Password and click ‘Login’. Otherwise, click ‘Register’ to create an account to use with CloudSURVEY (and the other Siretta websites). In this case, you will be redirected to https://portal.siretta.com/ where the account registration form is presented.
Complete the required fields, accept the privacy policy and click ‘Register’. Within a few minutes, an email from portal@siretta.com will arrive with a link to confirm the email address and complete registration. If it doesn't arrive, check the Junk folder and add portal@siretta.com to the safe senders list.
On first login to the CloudSURVEY portal, the system will send a welcome email to the you containing a brief overview of CloudSURVEY.
Configuring a SENTRY for the first time with SirettaSPARK will automatically link it to the portal, and it will be displayed in the Device List in CloudSURVEY.
It may take up to 5 minutes for the SENTRY to display online because it communicates with the server once every 5 minutes while awaiting instruction.

Tokens are a form of credit in CloudSURVEY. They are used with cell mapping and are consumed when a map is initially created or its view is refreshed to redraw the positions of found cells. One token is used to draw the map, and an additional token is used for each cell plotted on the map.
SENTRY surveys are real-time events; thus, tokens are used as cells are discovered, unlike SNYPER surveys which are uploaded after the event. Viewing a previously created map without refreshing the cell locations also consumes one token.

This sends a request to sales@siretta.com to add 500 tokens to the user’s account. Normally this request will be actioned within 1 working day, UK weekends and holidays excepted. A confirmation email from portal@siretta.com will confirm the addition of the tokens. Note that the granting of tokens is a manual process and subject to use of service checks. Once requested, the button will no longer be available.
Once granted, a token count can be seen to the right of the user icon.

Tokens are only required to use the mapping functionality of CloudSURVEY. CloudSURVEY will always allow surveys to be stored and viewed, even when there are no remaining tokens on the account. Tokens are not required to be able to control and use SENTRY.
SENTRY is a cellular surveying tool that integrates with CloudSURVEY in two ways:
Once logged onto the Siretta portal, navigate to Resources > SirettaSPARK Tool or navigate there directly using this link: https://portal.siretta.com/portal_siretta_spark.php.
Download and run the SirettaSPARK application. You need to register SirettaSPARK to the account you created. Refer to the SirettaSPARK User Manual for details on how to use SirettaSPARK.
In the SPARK tool, click Connect device then click Configuration and enter the APN and any username/password/PIN required by the SIM card provider, and save them to the SENTRY.

The account to which a SENTRY is initially paired is considered the owner of the SENTRY on CloudSURVEY.
To use a SNYPER with CloudSURVEY, it must be configured to produce an HTML report for each survey, which is the default factory configuration.
This is not applicable to both 5G-Graphyte and IoT-Graphyte SNYPER models. This setting can be found from the Main Menu of the SNYPER by navigating to Setup > Documents and checking that HTML is set to ON.
Every device (i.e. SNYPER or SENTRY) used with CloudSURVEY is judged to be owned by a single user. The owner of a device has full rights to the device and may grant permissions to other CloudSURVEY users to view surveys, and in the case of SENTRY to conduct new network surveys. Rights granted by the owner to other users may be removed at any time by either party. Ownership may also be transferred from one owner to another.
A device owner may always see which of their devices are shared, and with whom. Similarly, a user who has been granted permissions can always see which devices they have been granted permissions to view, and who the owners are.
CloudSURVEY is used to control the start, duration, and survey conditions of SENTRY cellular network surveys. CloudSURVEY is essential for the operation of a SENTRY and viewing the surveys it produces. In contrast, SNYPERs operate as a standalone product, conducting surveys independently of CloudSURVEY. CloudSURVEY enhances the SNYPER by offering additional features such as cloud storage, management, and mapping tools.
For SNYPER models: LTE, LTE+, LTE Graphyte, LTE-M, ensure the HTML document setting is turned on (default).
Connect the SNYPER to an internet-enabled PC then open and view the HTML survey file in a web browser. Refer to the SNYPER User Manual corresponding to your specific model for details on how to create a survey and view the resultant HTML file (click here for Siretta’s document library).
Scroll to the end of the survey page. Find and click on ‘Store Survey Results in CloudSURVEY’.

You will be redirected to the CloudSURVEY portal login. Once signed in, the survey will be displayed and automatically stored. If this is the first time accessing a survey on the SNYPER in CloudSURVEY, the signed-in account will become the owner of the device.
Clicking the link at the bottom of the HTML survey file will always show the survey in CloudSURVEY. However, it will only be saved to the account if the viewer of the survey is either the owner of the SNYPER or has permission to view surveys from that SNYPER.
Cellular network surveys using SENTRY are set up and initiated either from the CloudSURVEY portal or by using the CloudSURVEY mobile app, available on both Android and iOS.
In the CloudSURVEY portal, all online SENTRYs are displayed in the Device List. Each SENTRY can be identified by its 6-digit device ID, which corresponds to the last 6 digits of the serial number printed on the product label.
After the LEDs indicate that the SENTRY is online, it may take up to 5 minutes to appear in the device list. The controls used to perform a survey with the SENTRY are highlighted below.

If an account has more than one SENTRY assigned, each unit will have its own independent controls.
If a SENTRY has previously conducted an initial survey, an additonal button will be displayed for viewing a list of all previous surveys and any that are currently in progress:

Hovering the cursor over any of the buttons will display a pop-up window with additional information. This is particularly useful when the SENTRY is surveying if the session start/resume button is hovered over as it shows the running and remaining time:

| Button | Feature | Description |
|---|---|---|
|
Session Start | Click to start a survey with the current configuration. CloudSURVEY synchronises with the SENTRY. |
|
Wait for SENTRY synchronisation | Synchronisation information message. CloudSURVEY moves to surveying when synchronisation is complete. |
|
Session Pause | Surveying is in progress. Click to pause the active survey session. |
|
Session Stop | Click to stop an ongoing survey. |
|
Configuration | Click to edit and save the SENTRY survey configuration settings (see Sentry Configuration). |
|
Survey History | Click to see a list of all conducted surveys (see Sentry Survey History). This button is available after a survey has been completed. |
Click the Configuration button and set the survey parameters (see SENTRY Configuration).
Click the Session Start button to start surveying.
If and as necessary, click the Pause/resume button.
If necessary, click the Session Stop button.
Surveying concludes when either the configured end conditions are met or the stop button is pressed, whichever occurs first.
View the survey (see Viewing all Survey Results).
The SENTRY should be configured before first use. This ensures it is set up for the correct survey type and duration. The configuration page and meaning of the fields are explained below.
The configuration settings may not be updated while a survey is in progress. Any changes made during an active survey will terminate it and initiate a new one with the updated configurations.

The name of the network provider can be entered to initiate a searchable drop-down menu which is filtered by the values entered. For example, enter 'vodafone' and the list shows all global Vodafone PLMN identifiers from which to select.
Serial Baud Rate: specifies the baud rate to be used on the serial port. Data is always 8-bit, 1 stop bit, no parity.
Select from the following options:
Survey Duration: Determines the total duration of the survey. The survey duration counter starts when the first network scan is posted to CloudSURVEY. So if the SENTRY is not powered, the timer doesn’t start until the SENTRY has powered up and sent the first scan data back to CloudSURVEY. Any scans in progress when the timer expires will be completed, resulting in the survey duration reported by CloudSURVEY being slightly longer than the requested time.
Select from the following options:
SIM Phone number: Enter the phone number of the SIM card used in international calling format (i.e. with a leading ‘+’ and country dialling code). This may be used to improve the responsiveness of the SENTRY surveying by allowing CloudSURVEY to send text messages to the SENTRY with instructions rather than waiting for the SENTRY to contact CloudSURVEY.
New Survey Control: Controls how surveying behaves in the event of a power interruption.
Select from the following options:
Cycle Time: This is the time interval between the cellular network scans taken by the SENTRY. All network scans performed are collated into a single survey report. The survey report may be examined while surveying is in progress and will show the results of the scans already completed.
Select from the following options:
Push Updates: Enabling push updates allows CloudSURVEY to send SMS to the SENTRY thereby improving the response time of the SENTRY to commands issued by CloudSURVEY. For this to work correctly, the SIM card must be enabled to receive such SMS messages.
SIMs with International Network country code (+882 and +883) numbers can behave differently with respect to text messaging compared to normal SIMs and may not work with this setting, dependent on SIM provider.
Clicking the Survey History button will display a list of all surveys initiated on this SENTRY. This includes any surveys that are currently in progress.
This differs from the ‘View All Surveys’ list because it provides the start and end times along with details on the user that initiated the survey.

Siretta has developed the CloudSURVEY mobile application as an alternative method to controlling a SENTRY. This app is available for both Android and iOS on the Play Store and App Store, respectively. Simply search for 'cloudsurvey' in the store.
The app connects to the CloudSURVEY portal using a mobile view, making it easier to use on devices with smaller displays.



The controls on this page work in the same way as the web browser version of CloudSURVEY (see Using the CloudSURVEY portal to initiate surveys).
After logging into CloudSURVEY portal, the Device List page is displayed. This lists all the devices that are associated with the account – owned devices and devices to which the account user has viewing rights. This is the home page from which all the functions of CloudSURVEY are accessed.
The portal view is divided into three sections.

The top header contains the four main navigation buttons and some additional information:

See CloudSURVEY Account Management.
This lists all owned devices and those to which viewing permissions have been granted.

|
Indicates that you are the device owner and ownership is not shared with any other user. |
|
Indicates that you are a device owner and ownership is shared with one or more other users. |
|
Indicates an un-owned device to which viewing rights have been granted. |




Selecting ‘View All Surveys’ from the top menu shows all surveys saved to the CloudSURVEY account. This is a comprehensive list of surveys from all devices on the account. The list can be refined with filters or search terms and is organised by survey types (5G, GSM, LTE, LTE-M, NB-IoT, etc.), then by date and time.

Click the calendar icon to change the month and year or click in the dd, mm and yyyy fields to enter the values.
Selection checkbox only available for devices which have the full survey results unlocked.

By default, surveys follow a similar layout as shown in the example below.
This default layout may be changed in the settings (see Settings).

The Survey Filter Header you to apply individual filters that apply to both the map and cell listing.
The survey map shows the identified positions of all cells around the survey location.

The map can be navigated and zoomed in/out using the controls at the bottom-right of the map:

Alternatively, navigate the map by clicking and dragging the map as desired, or zoom in and out of the map by holding the Ctrl key while using the scroll wheel.
Position markers indicate the location where the survey was conducted, using three types of pins based on the location determination method:
By default, an orange pin is used. SENTRY surveys conducted using the GNSS antenna will display a blue pin. Although unlikely, an orange pin might also appear on a SENTRY survey map if the GNSS receiver fails to determine the position.
To reposition an orange marker on the map, click and drag the pin to the desired location. When you release it, the marker becomes a user-defined position pin (turning green). Click on the pin to view the location details.
Cell markers indicate the physical location of a cell on the map. They can be represented by a single icon or a cluster icon depending on cell density and the map’s zoom percentage.
| Icon | Name | Description |
|---|---|---|
|
|
Cluster icon | Represents multiple cells in close proximity. Clusters of 2–9 are blue, 10–99 are yellow and 100+ are red. |
|
Yellow 5G NR/SA pin | Represents the location of a 5G cell. |
|
Green 4G pin | Represents the location of a 4G cell. |
|
Red 2G pin | Represents the location of a 2G cell. |
|
Orange LTE-M pin | Represents the location of an LTE-M cell. |
|
Pink NB-IoT pin | Represents the location of an NB-IoT cell. |
Cell placement information is generated using third-party mapping and location data services through the Google Maps API. CloudSURVEY uses these services to provide worldwide coverage and to support ongoing refinement of estimated cell locations. Cell tower positions are continuously updated as new data becomes available, and new cells are regularly added to the database. As a result, a missing cell marker may still display in the future.
These options provide the user with the ability to refine and restrict the information on the map to certain criteria. For example, it can be used to isolate and display only cell types of a particular network technology. Buttons will display bright when selected and dim when deselected.





Position: Show or hide any position markers on the map.
Cluster: Enable/disable cluster icons on the map regardless of zoom level.
Information: Enable/disable additional information when clicking on a cell.
Recenter: Reposition the map to a central position in relation to located cells.
Comments box: Provide any comments here.
Bookmark: Change the bookmark displayed on the survey.
Save Bookmark and comments: Save any changes made to bookmark and/or comments.
Sentry devices can perform a travelling survey using a GNSS antenna. This survey method tracks the device from its starting point to its destination, recording the route taken and all cells encountered along the journey. Recorded metrics include:

| Icon | Name | Description |
|---|---|---|
|
Direction arrow | A marker indicating the recorded position and direction of the device at a given time. These markers are placed along the route taken. Clicking on one reveals further details. |
|
Start location | Represents the starting location of the survey. |
|
End location | Represents the ending location of the survey. |
By default, a Survey Overview dashboard is displayed at the bottom of the page below the Survey Map. This provides a clear snapshot of key survey information.
The Survey Overview is the default view but this can be changed in settings (see Settings).

The Survey Overview dashboard comprises the following interactive widgets:
The Network Summary tab provides a tabulated breakdown of all detected cellular networks.
Each cellular technology is displayed within its own collapsible section, making it easy to navigate between them. For each technology, the key metrics are illustrated using bar charts, showing the number of detected cells, network dominance percentages, and signal variability. Hovering over any bar will display a tooltip with some additional context.
A dedicated Combined Network Summary section consolidates data from all recorded technologies into unified charts, allowing for easier comparison of overall network dominance and signal stability across all major providers.

Network summary is a rolling tally of the cells within each signal band.

Network dominance is determined by how often an operator appears, along with the strength of its recorded signals.

Network Variability provides insight into signal stability for each network operator.
Each box plot displays the range and distribution of signal strength values. The vertical lines (whiskers) represent the minimum and maximum values recorded, while the central block (box) shows the interquartile range, where the middle 50% of the data lies.
A narrower box indicates more consistent signal strength, while a wider box suggests greater variability.

The Distribution Matrix offers a comprehensive breakdown of network performance using heatmaps and pie charts. Each network technology is analysed using key data visualisations that map the relationships between network providers and frequency bands.
RSRP and RSRQ metrics are not applicable to 2G and therefore are not shown for this technology.
This heatmap displays the average signal strength (in dB) for each network operator across specific frequency bands. It provides insight into how well each carrier performs on each band in terms of signal quality.

This heatmap displays the average Reference Signal Received Power (RSRP) values (in dBm) for each network operator across specific frequency bands.

The following table provides a guide for interpreting RSRP measurements and assessing cellular network signal strength:
| RSRP (dBm) | Signal Strength | Quality |
|---|---|---|
| ≥ -80 | Excellent | Very strong coverage |
| -80 to -90 | Good | Reliable service |
| -90 to -100 | Fair | Acceptable coverage |
| -100 to -110 | Poor | Coverage becoming weak |
| -110 to -120 | Very Poor | Unreliable service |
| < -120 | Extremely Weak | Coverage likely unusable |
This heatmap displays the average Reference Signal Received Quality (RSRQ) values (in dB) for each network operator across specific frequency bands.

The following table provides a guide for interpreting RSRQ measurements and assessing cellular network signal quality:
| RSRQ (dB) | Quality |
|---|---|
| -3 to -9 dB | Excellent |
| -10 to -12 dB | Good |
| -13 to -15 dB | Fair |
| Below -15 dB | Poor |
This heatmap shows the number of cells observed for each carrier-band combination. It reflects how frequently each band is used by the respective network operator, helping assess network deployment strategy.

This chart compares the signal strength distribution measured across network operators. The white dot within each coloured bar indicates the average signal level for each operator, while the coloured bar represents the range (variability) of signal strengths discovered during the survey.
Stronger signal is represented by values closer to 0 dB, while weaker signal is represented by more negative values.

This chart compares RSRP across network operators, highlighting the relative strength and consistency of their signals. The white dot within each coloured bar represents the measured average RSRP values for each operator, while the coloured bar represents the range (variability) of RSRP values.
Since RSRP is measured in dBm, values closer to 0 dBm indicate stronger signal strength, while more negative values indicate weaker reception.

This chart provides a percentage-based breakdown of how often each frequency band appears across all observed networks. It’s essentially a tally of the columns from the band density heatmap, highlighting which bands are most frequently utilised.

This chart shows the percentage of observed cells for each carrier, effectively a tally of the rows in the Band Density Heatmap. It reflects how much coverage or activity each network operator has in the dataset.

All cells discovered during the survey are listed within this section. By design, a SENTRY surveys only one network technology at a time, whereas a SNYPER, depending on its configuration, can produce a survey covering all network technologies.
The reported information can differ depending on the network technology surveyed. These differences occur because of the differences in the technologies.

Cells are listed in descending order of signal strength, with the strongest at the top and weakest at the bottom.
Hover over the green upside-down triangle icon to reveal the latitude/longitude of the cell. Clicking it will bring up its exact location on the cell map. Although uncommon, a red triangle indicates that the cell position could not be located on the map. This is more likely with a very low signal strength cell, an NB-IoT cell, or where some information may have been corrupted.

Journey telemetry is only applicable to travelling surveys. It provides an overview of a recorded journey, combining cellular coverage data, GPS telemetry, and speed metrics.

The Journey Summary displays an overview of the entire journey recorded during the survey:
This speedometer-style gauge visualises the speed profile of the journey:
This is a timeline chart showing how GPS visibility varies over the course of the journey. The plotted orange line represents the number of GPS satellites visible at each point in time. A higher number generally results in better location accuracy. Hover hover a data point on the line to reveal more information.
This is a box plot summarising the distribution of satellite counts during the journey. It helps in assessing the reliability of GPS tracking across different areas (e.g. fewer satellites might indicate signal blockage due to terrain or weather).
Network Performance Monitoring is a survey feature available exclusively for the SENTRY. It runs a performance scan on the SENTRY’s active cellular network, evaluating the real-world performance of its connection beyond basic network availability and signal-level measurements.
The feature monitors key connectivity metrics, including:
Each metric is presented through a dedicated gauge or chart, providing a clear overview of network performance and enabling quick identification of connectivity issues.
To display these metrics, both the Operating Mode and Network Steering must be configured in the SENTRY’s Device Settings before the survey is performed. Set the Operating Mode to ‘Post Network Survey & Performance’ and configure Network Steering to ensure that the SENTRY consistently tests the intended network and cell.

A Sentry survey which has been configured for Perfomance Monitoring will have the following icon displayed against it in the Survey Results list: ![]()
Performance Monitoring measures the cell that the SENTRY is connected to during each survey. The SENTRY does not automatically reconnect to the same cell with each survey, so there is the possibility that the SENTRY could test different cells upon subsequent surveys. To ensure consistent testing of a particular network, Network Steering should be configured in the Device Settings before starting the survey.
Four primary parameters are graphed over time for comprehensive analysis:

This evaluates the throughput capabilities of the network. The SENTRY connects to cloud-survey.co.uk to determine average upload and download speed. The SENTRY uses an LTE Cat 4 modem, so the maximum theoretical speeds that can be achieved are:
| Technology | Max Download | Max Upload |
|---|---|---|
| LTE | 150 Mbps | 50 Mbps |
| UMTS (HSPA+) | 42 Mbps | 5.76 Mbps |
| EDGE / GPRS | 296 kbps | 236.8 kbps |
Real-world values often fall below these theoretical maximums due to factors like network congestion, cell tower limitations, and signal interference.

These charts provide a side-by-side comparison between the current SENTRY survey results and the monitored network provider’s overall averages from other surveys.
The comparison includes the total registration time and the time taken for each stage: cellular registration, TCP/IP registration and socket registration. This helps identify whether performance at the current location is typical for the network or whether delays are occurring during a particular stage of the registration process.

The Registration Performance chart compares the time taken by the SENTRY to establish a cellular connection with the selected network against the benchmark result. The upper bar shows the benchmark registration times, while the lower bar shows the registration times measured by the SENTRY.
Each bar is divided into cellular registration, TCP/IP registration and socket registration stages. The duration of each stage is displayed in seconds, allowing performance differences and delays in the connection process to be quickly identified.

Every device used with CloudSURVEY is associated with an owner. The owner of a device also has ownership of the surveys conducted by that device on CloudSURVEY. The owner can grant permissions to other CloudSURVEY users to view surveys from their device.
SENTRY owners can also authorise other users to set up and conduct surveys.
Ownership of an un-allocated SENTRY is assigned to a user using the SirettaSPARK tool. Upon connecting the device and opening the software, the user will be prompted to allocate the device to their account.
An owner may choose to relinquish ownership over a device in one of two ways:
Ownership of a SNYPER on CloudSURVEY is established by the first user to access a survey conducted by the device. Possessing the physical device does not confer ownership from CloudSURVEY’s perspective.
Ownership Permissions can be managed by clicking on the ownership icon to the left of the device in the device list.

This action will display a page listing all users who have access to the device, providing options to add new users, remove existing users, or transfer ownership.

Click View Account in the page header to access account settings. From here, you may customise display options, change account settings, track token usage, and manage other preferences.
The page is divided into separate tabs:
Provides clear overview of your account at a glance. Displays the total number of registered devices, stored surveys, token usage and more. All presented in a simple, visual format.

The settings tab lets you customise how survey data is both displayed and interacted with in the CloudSURVEY portal. You can toggle features on or off.

CloudSURVEY is free to use with core features available to all users. For those who require enhanced capabilities, we offer an optional subscription-based service with tiered plans to suit different levels of usage. Our subscription plans: Premium and Premium Plus, provide access to advanced features and a monthly supply of tokens. These plans are ideal for users who need more in-depth insights.
On subscription, premium tokens are automatically added to the account and will subsequently be added every month on the date of the initial purchase. For example, if you subscribed on the 13th of January, the tokens will refresh on the 13th of February and continue on the 13th of each following month. Any unused tokens will not roll over at the end of the month; instead, a new allocation will be made to the account.
Users may still purchase additional tokens separately while using the subscription service. Non-premium tokens purchased this way behave as normal and will remain in the account beyond the end of the month.
The personal information stored in CloudSURVEY for the account owner is shown in the account area. For new accounts, some fields may appear with a red background, indicating incomplete information. Any fields that are already populated were collected during the portal account registration process.
Complete the Personal Information section if you wish to enable token purchases.
