I have a problem with my sim-card. It does not connect to my provider, but when i put in a other phone it works. When i put a different card in my phone it also works. I already tried to restart and reset connection settings.
When I go to setting and choose mobile network it only shows my phonenumber. So the phone knows there is a card in it.

Somebody knows a solution, thanks?
