First off, im US based. While I was in Switzerland 3 weeks ago and all international trips prior (Canada, Mexico, china, etc) my phone worked fine. I landed in Frankfurt Germany and I'm getting zero signal. Phone is set to global mode. I had to do a factory reset, so I suspect that my sim card didnt set itself for global mode? If this is the case, am I able to turn global mode on in the sim card without a signal? I have a feeling I know the answer, but i thought I would ask anyways.
Thanks!
