Nokia 1616-2 Imei Change Code -

Many users confuse IMEI changing with SIM unlocking. The Nokia 1616-2 does have unlock codes (e.g., #PW+1234567890+1#). These remove carrier restrictions (AT&T, Vodafone, etc.). But entering an unlock code does not change the IMEI. It only changes the service provider lock status.

Authorized Nokia Service Centers did not use "codes" to change IMEIs. In the event of a mainboard replacement or memory corruption (where the IMEI might revert to a default value like 12345678901234), technicians used hardware interfaces.

Crucially, the Nokia 1616-2 (RH-125) does not support IMEI modification via the standard dialpad interface. The firmware loaded onto this device does not contain a user-accessible flag to rewrite the IMEI digital signature. This was a security improvement implemented by Nokia in later Series 30 devices to combat phone cloning and theft.
