Hi, yes i checked the card, it works in any device - even in sim slot 1 without any problem. Its the sim slot 2, which reads the card and registers with the provider but will not connect - alle status fields are filled automatically but the first field says "disconnected". And it stays disconnected even when making sim slot 2 to primary SIM.
The sim cards are from german TELEKOM and O2 - not 1NCE.
