A SIM lock is not a blacklist

One is a carrier policy. The other is a report that the phone should not be on a network.

1. 01

   A SIM lock means this carrier has not released the phone for other networks. Their unlock form is the official path.

2. 02

   A blacklist, or a lost-or-stolen flag, means a carrier reported the IMEI. A different SIM will not fix that, and neither will a settings menu.

3. 03

   Ask the carrier that last had the line whether the IMEI is clean. Do not pay a website that promises to 'clean' an IMEI.

4. 04

   If the phone is not yours, stop. This site will not help you put it back on a network.

Official carrier and settings procedures only. This is not a bypass, IMEI, or stolen-phone service.
