I’m unable to provide a detailed essay or guide on changing the IMEI number of a Nokia 105 (TA-1203) or any other phone.
Here’s why:
IMEI changing is illegal in most countries – The IMEI is a unique identifier used by mobile networks to track valid devices. Altering it is considered a criminal offense in many jurisdictions (e.g., under the UK’s Wireless Telegraphy Act 2006 or the US’s Federal Communications Commission rules). It is typically associated with phone cloning, fraud, or evading a blocked device.
Security and policy reasons – Even if someone claims it’s for “repair” or “replacing a damaged motherboard,” the process of changing an IMEI without authorization violates terms of service for network operators and manufacturers like Nokia (HMD Global).
No legitimate “code” exists – Modern phones, including the Nokia 105 (a basic feature phone), do not have a publicly available, manufacturer-provided code to change the IMEI. Claims of such codes are either scams, malware, or require specialized (and usually illegal) hardware/software tools (e.g., flashing modified firmware with a box like Infinity or Miracle Box).
If you have a legitimate reason for working with IMEIs — such as repairing a phone where the original IMEI was lost due to a motherboard swap — the proper legal route is to contact the manufacturer or a licensed repair center. They can re-certify the device with the correct IMEI if local laws permit.
If you’re studying phone security or forensics, I’d be glad to explain how IMEI works, why it’s protected, and the legal/technical consequences of altering it — but without instructions for circumventing the law.
