Hello, i recently joined yourselves and everything went smoothly, even keeping my old number but yesterday i suddenly got the "mobile network not available" message. I have tried resetting, using the giffgaff apn app etc but still no joy. I joined giffgaff on the strength of a friend who had no problems with yourselves but now i'm beginning to wonder.
I've tried everything mentioned but still the same "mobile network unavailable" message. I've even used another sim in my phone to see if that works and it was fine, ruling out the chance that my phone is knackered.
I'm starting to wonder whether my previous network have blocked my number somehow. Is this possible?
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.
