I have a rooted galaxy s2 which is unlocked now and was on Vodafone which I've put a payg o2 sim In to.
Problem is I can get any network signal. It finds the sim and I select o2 payg from the list and can even download property moments from the store but the network not registered sign always pops up when I try to register the sim.
Any thought as to why I can use the sim in it?
It also doesn't work in just normal o2 mobiles as have tried in a friends.
