I have recently changed from a micro sim to a nano sim and now my phone does not pick up the sure signal. The signal still works because my grandson's phone which is registered to the signal still works.
I was informed that you have to deregister and then reregister my phone because I am the administrator.
Everything is now OK thank you. The problem lay in the fact that the sure signal was talking to my OLD sim although I had not changed my number. One of your guys married the sure signal to my new sim and Bob's your auntie!!!
