Is this a new phone and contract ?
Are you porting in a number from another network?
Can you give us more info on the problem - calls and texts and data not working or just one or two of those?
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion.
