How To Unlock Most Cell Phone

@cadu1995 It more or less deletes all the data on the phone. It allows you to use the phone on another CDMA-based carrier or service provider.

@cadu1995 MetroPCS uses CDMA technology, and there’s no unlocking solution yet for CDMA phones. There’s only a flash software for those phone models.

@Mr99hockeyrules The phone used on the video is a Samsung model. And here’s how to unlock it:
1. Switch ON your phone without SIM Card.
2. Compose: #7465625*638*CODE# (or *#7465625*638*CODE#).
3. Device should say: Network Lock Deactivated

@Margaritosan You can’t. You’ll only block the phone if you try too many times.
