I've just replaced my phone screen and reinserted my SIM to my Nokia Lumia 520, but my texts are not sending. If I turn the Wifi off and turn Mobile data on I can connect to websites - so it is just the messaging that isn't working.
I have changed the SMS Centre Number to +447958879890, is this correct?
Welcome to the community and thanks for posting. I'm really sorry to hear you can't send text messages.
The SMS centre number is correct. Have you tried taking the battery out of the phone while it's on? Have you also tried factory resetting the handset?
We don't have access to mobile accounts via the forum. So if the issue persists please contact the team on 789 from a Virgin Mobile handset or 0345 6000 789 from any other phone and they'll be able to look into this further.
