On 7/6/14 I bought a new mobile phone (Samsung Galaxy Fame) from Carphone Warehouse. I kept my sim card and data card to continue with the same number on T mobile pay as you go because I had around £15 credit left on it and I was happy with this network. The phone has been fine up to yesterday. On Thursday I had 3 missed calls from T Mobile-all between 14.00 and 15.00 when I'm at work and my phone is in my bag in a locker. I checked the calls and there was a message saying "this call was from T Mobile you need not do anything about this call" Today I have been unable to ring out, receive calls or make /receive texts-getting a message "Not registered on network". The EE/T Mobile web site -which I am registered on is unhelpful with no facility to do web chat with expert but I am beginning to think that the phone has been blocked-presumably by TMobile. Anyone had the same problem? I'm going back to Carphone warehouse next week to see the man there-who I know and who is very helpful. What did I do wrong? I expected that keeping my number and sim card and just changing the handset would be simple!
If you don't make a call for a certain length of time (a number of weeks or months, not sure) the number is withdrawn to be reused at some later date by somebody else.
