I have recently come back to the UK after travelling and am unable to take calls or sent texts with my phone. When I try it just says message failed to send however my data is on with the correct SIM card and I have tried restarting my phone to see if this helps, but it still does the same. I wonder if you may be able to help with this issue?
my mobile data still works so I don’t know why the messaging and calls don’t.
hope to hear from you, many thanks!
