Hey people! So I just bought an iPhone5c 16gb today about 15:00 on O2 for £28 a month. I've put micro sim in and gone through the set up etc and everything works perfectly fine, Internet (4G/ wi-fi), can call people, take calls, use App Store pretty much everything, except for whatever reason I can't send normal SMS messages. Also iMessages work but they send from an email address instead of the number, a number doesn't come up in the 'send & receive' drop box. Looked on a few forums and reset network connections taken sim out, with a few other things, also done a full reset and fine through set up again. Still won't pick up the number in send & receive drop box or send SMS. Tried live chat earlier but failed to find help and they are offline now. Need help on this one, only other thing I've seen is I've got a dodgy SIM card, but still don't understand how everything else is fine? Thanks. C
