I need help in unlocking my phone which is a Nokia 3120b. Here is the information: Model 3120b Type RH-50 IMEI 356245005180005 Code 0524012LM20TJ Thanks in advance..
When I enter the number without the SIM card I get the following message "Cannot undo restriction" doing it with the SIM card I get the message "Phone restricted". Do you have any idea what is going on?
