  • I have just swapped my sim as I've recently just upgraded but when I try to send a text or make a call, I get a message come up saying I'm not on a registered network. Anyone know how to resolve this issue?

You'll need to reboot the phone with the new sim in it.

If it won't connect, you'll need to call O2 on another phone or by using Skype.

When it comes to the reason you are calling stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
Say "Upgrade", "Lost/Stolen" or "Fraud" if you have to, to get put through to someone.
8.00am is the best time to call if you can.
