Ok, so I am actually not really sure wants wrong here, but for some reason my FP2 seems to have a problem with a certain german provider called 1&1. I got a laptop sim card from them to make the most of my dual sim with 3GB traffic a month (LTE).
The thing is, that my android seems to have this card locked at 2G with no way to choose. I tried to other sim cards and they both worked fine, they were set on 4G and I was able to choose 3G or 2G (not that anyone would want to that). The provider already sent me a new sim card, but it has the same problem. I switched the sim slots, nothing happened. I tried the sim card in my girlfriends phone, 4G internet, no problem. Does anyone have an idea what I can do about this? I signed a 2 year contract for 10€ a month for this card, so it would REALLY suck if it didnt work!
