I have just returned from belgium after having roaming on whilst over there, but as soon as i returned to the uk I have no service. I still have data on my plan, have not missed a payment and I have tried turning off automatic connections for a minute then turning it back on, any help would be greatly appreciated

Hi ​@Moth3747

 

Welcome back! I’m sorry to hear you're experiencing service issues upon your return from Belgium. It’s a common technical "hangover" where the SIM remains stuck searching for a foreign partner network instead of reconnecting to our UK masts.

 

Since you have already tried toggling automatic connections and verified your payments/data, we need to take more decisive steps to force the SIM to re-authenticate with the Three network (our UK partner).

 

Troubleshooting Steps
Please perform these steps in the following order:

  • Perform a "Hard" Network Refresh:
  1. Go to Settings > Mobile Data > Network Selection.
  2. Turn off Automatic.
  3. Wait for the list to populate (this may take a minute) and manually select a network you cannot use (e.g., EE or O2).
  4. Your phone will show "No Service." This is intentional as it clears the previous roaming cache.
  5. Now, manually select iD or Three. Once it connects, switch Automatic back on.
  • Toggle Flight Mode (The 60-Second Rule):
  • Switch Flight Mode ON for a full 60 seconds, then back OFF. This force-restarts the modem's search for local masts.
  • Reset Network Settings:

If the above fails, you may need to reset your network configuration.

  • iPhone: Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
  • Android: Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth.

Hello,

im having the same problem. Returned from 3 weeks in Vietnam where was using an eSIM and now have no service since switching back to my primary sim in the UK. Have tried all of the above steps but still showing no service despite performing hard network refresh following the steps above, toggling flight mode for 60 sec and resetting network configuration on settings. Up to date with bill and have tried taking SIM card and replacing it.

 

Do you have any advice to resolve this issue?

 

Many thanks
