There is no secret keypad code that can change the IMEI of a Nokia 1616-2. The IMEI on Nokia devices running on the Series 30 (S30) platform is hardcoded into a protected, read-only memory section of the phone's hardware, deeply tied to the baseband processor. Technical Realities of Nokia Firmware (DCT4 / Infineon)
If your phone is locked to a specific carrier (e.g., Vodafone, T-Mobile, AT&T) and displays "Restriction On" or "Invalid SIM" when you insert a different provider's card, you need an , not an IMEI change.
If your goal in changing the IMEI is actually to use the phone with a different network carrier (network unlocking), you do not need to change the IMEI. Instead, you can unlock the phone legally:
In the tool's interface, look for the phone information panel. In professional service manuals, this is often referred to as the "Phone Identity" dialog box. Within this section, you should find a field labeled . This is where you would input the new IMEI number.
The IMEI of a Nokia 1616-2 is a unique, factory-assigned identifier that cannot be changed using a secret dial code. Modifying this identifier is technically difficult, often requiring specialized hardware, and is illegal in many jurisdictions.

If your Nokia 1616-2 is not picking up a signal or says "SIM Not Valid," you likely do not need an IMEI change. Instead, you need to address network compatibility or carrier locking. 1. Check Network Compatibility (The 2G Shutdown)
operates on an older Nokia platform (typically DCT4 or early Series 30). Modifying the IMEI in this era required more than just a software code:
Tools like J.A.F., MT Box, or Cyclone Box (historically popular) were required.
* The #06# Code: This is the standard GSM code to display the IMEI (International Mobile Equipment Identity). It is a read-only query. It does not access a writing mechanism.
If the device cannot be activated due to network deprecation (such as the shutdown of 2G networks in your region), consider recycling the phone responsibly. To help point you in the right direction, let me know:
