Devices Set up & Troubleshooting
We will go through a few steps to troubleshoot a device that has no access to data in roaming
If the SIM didn’t work on the national network before going into roaming, the problem is probably with the SIM configured services / device settings, and nothing to do with roaming.
Check the national troubleshooting first.
Your phone should show at the top of the screen or under the network settings:
– it is connected to a network
– good signal strength (warning: if only 1-2 bars an internet page may take a while to load)
– The technology (2G, 3G, 4G or 5G). If using 2G, data may take a very long time to load. Under 3G, things should be fairly quick (warning: many countries and networks are decommissioning 3G). With 4G/5G and a good signal, internet pages should load almost immediately.
If you’re not showing a network or good signal and technology, you can try:
– Toggling the network on and off
– Manually search for a network
– Turn the device on and off
– Move to a different area where there is good reception (either use the coverage checker of a local operator, or check another device
If you are an MVNO which has subscribed to capped bundles: roaming voice, SMS and data are blocked by default to prevent bill shock. The subscriber must purchase a Daily Roaming Pass to have access to data by sending an SMS to 1250.
Otherwise, you can provision the subscriber to “Tiered data” to give them access to open-bar data nationally and in roaming.
Using our SIM Management platform, you should check that the SIM has been provisioned with:
– Data technology: should be set as 3G/4G/5G to guarantee access. 3G/4G should be okay as well, but the user won’t have access to 5G. 2G/3G may have some restrictions in countries where 3G networks have been decommissioned.
– Roaming Voice, SMS and Data Open from All Zones or Roaming Voice, SMS and Data Open from Zones 1 Only (if roaming in the EU and continue to block access extra-EU) to open roaming services.
Transatel’s data safeguarding solution may have stepped in to prevent the subscriber from bill shock. This will block access to roaming data to prevent the subscriber from going over £45 of roaming data usage.
The subscriber will have received an SMS informing them that they have hit 80% of the threshold, and again when they have reached the threshold. They are prompted to reply “OK data” to acknowledge the charge and to continue using data.
You can check if this has been hit on the check-up: 
Alternatively, it will also show on the Plans and Options tab: 
Here, you also have options to open the data access back up.
More information on Data Safeguarding can be found here.
Even in roaming, the national APN settings still apply. Check that your device has the right APN settings found here.
Turn the WiFi off: sometimes the phone will be connected to a WiFi network which is defective. Turn WiFi off to see if you are experiencing an issue with the mobile network.
For example, if you have arrived by aircraft, some planes provide their own WiFi network that may not work when grounded or may require an internet package to be purchased to access the internet.
Sometimes the handset has been configured to disallow access to roaming data. This can be different per device – check with the handset manufacturer for a complete guide on what options are available
Most commonly, we have:

– Android: Open your Settings app and tap Network and Internet or Connections. Depending on your device, these options may be different.
