Hi , i dont know if the nokia is locked but when i insert sthe sim card it asks for the PIN code then for a security code now i dont know the security code i forgot it. Any help of how to fix it ? the IMEI 355385003137094
That's the only code for it unless 1234 or 12345 will work. Sim card registration failed is because the sim has expired and is no longer any good. No more time is left on it.
