I am on 4G contract with O2 for iPhone. Using a new number has transfered from another network on 18th Sep 2014 (7 days by now).
I can send texts but can't receive them, I can make and receive calls, and use data. I've reset the network, turned the phone on and off, swtich off iMessage to use text only, put my phone number under "Phone -> My Number" reset the phone, swithed carrier to another provided and swithed back to O2. None of them worked. Please Help!
I have put another of my friend's o2 sim card in my phone, I can received text messages. I have put my sim card in my friend's, I can't receive text message. This indicate that it's likely to be my account instead of my setting?
