Changing or cloning an IMEI can create serious legal and security problems. Buyers should understand the warning signs and avoid manipulated devices.

Why the IMEI should remain stable

The identifier is designed to distinguish cellular equipment. Manipulation undermines network and ownership records.

Common warning signs

IMEI in Settings differs from the box.

The seller says the IMEI was 'fixed' or 'rewritten'.

Multiple phones show the same identifier.

The device loses network access after reset or update.

Repairs and replacements

Authorized main-board replacement or warranty exchange can legitimately produce a new identifier. The owner should retain documentation that explains the change.

Buyer protection

Do not rely only on appearance. Verify the seller, invoice and account locks and follow the used-phone buying guide.

What to do if you suspect manipulation

Stop the transaction, preserve evidence and contact the manufacturer, operator or relevant authority.
