try rebooting your phone
try removing the battery and sim and then replacing them.
try turning airplane mode on and then off.

It certainly sounds like a problem not with your phone or settings but with either gg or your previous provider.
It's possible your old provider has cut off your number by mistake, it might be worth contacting them just to check.
Also, I think you should contact an agent here at gg, just to check your number port went through properly and there are no problems on your account. You can do this by clicking on 'help' in the top right hand side of this webpage, then select 'contact an agent' from the options.
Good luck

I forgot to mention, just to rule out a network outage in your area go to this page http://status.o2.co.uk/ and check whether everything is up and running in your area and that there is no maintenance work going on at the moment.
