I've been with o2 since forever, over 20 years.
All good, until this week.
I've just upgraded from one Iphone to another, and nothing is working on my new phone. A few days my old phone started to only work on wifi, not receive or send any type of message. It's a contract phone. In the o2 shop they changed my sim, and that solved the problem for a day. On my new phone, nothing works. I went into the o2 shop today, and the guy said it was fixed, but once I left it stopped working. He gave me another new sim card, my third, but that didn't work. Most features eg calculator, camera etc don't work.
Like everyone else, I really need my phone. At work I run a department in an NHS hospital, my colleagues need to be able to ring me, and I need to be able to ring them. I'm not desk bound. PLEASE HELP , thanks
