Some days ago my phone just disconnected from carrier network and now I don't have signal at all. I tried some ftf but with the same results.
The SIM card reader it's ok because I can read my SIM information with the app SIM Info and with the app Network Signal Info I noticed I receive my carrier signal but it shows NETWORK BLOCKED.
I don't know how, but it seems that my phone get locked. This is what I see in SIM Lock:
 Network 0
 Network subnet 0
 Service Provider 0
 Corporate 0
 SIM 0
Is my phone locked? How can I unlock it???
Thank you for your help!!
