Hi,

Well I tried my 3 sim with a turbo sim and had no luck, so I decided today to buy a o2 sim on pay and go and try it.

My Iphone is an American iphone locked to AT&T. The sim seemed to work, but didn't pick up a signal. Do I still need a turbo sim in this senario or should the o2 sim work? I'm going to give it till tomorrow, but I'm starting to worry that theres something wrong with my phone and thats why none of the sims seem to work

Any help would be appreciate, as I'm just getting no where and more and more frustrated.

Rachel
