From William in Norway,
I have a Samsun Galaxy model GT-N7100 note 2 cellular phone, which apparently by itself has changed into a mode that makes it impossible for me to phone or send text messages as it prevents me getting to the Network suppliers. It has also disabled my pin code on the Sim card. There appears a text on the screen, which I have not been able to get rid of, and which reads thus:
CSC: N71000JVFND3H/W: not active
RF: call date unknown
SSN at back of phone reads N7100GSMH
What can I do to get my phone in a functioning mode again? It has not helped to set the phone back to factory mode. Instead of that helping I lost all my contacts.
