Nokia 3330 Sim-Card Problem
I have this Nokia 3330 and it always says "Sim card not usable." I've already tried to unblock it with a code i found online, and that worked (after entering the code, the message "Sim not restricted" came up). But it still says "Sim card not usable." I also tried several Sim cards and none of them worked. Any ideas?
