• Carriers can detect mismatched IMEI vs. device model and permanently block the device from network access.
• Using such a tool to reactivate a stolen phone is a felony.

Legal & Safety Warnings

• In many countries, IMEI modification is a criminal offense punishable by fines/imprisonment.
• Carriers blacklist phones with mismatched IMEIs.
