Don't use free unlock (reset) codes to sim unlock your phone

A lot of people are searching for methods to sim unlock their Samsung mobile phone for free. I understand that you want to do it for free and there are some working methods out there.

I just want to advise against using RESET codes. Using reset codes you are more likely to end up with a 'phone freeze' where you first have to repair this to be able to use your phone at all. On top of that it is likely the reset action also resets the calibration settings of your phone. This could result is a phone with no reception or very bad reception. Reset calibration settings are VERY hard to repair.

So all I want to say; be carefull and don't believe everything you write. There are many companies investing thousands of dollars to create software to unlock phones, they do this for a reason! Many people on forums just post the codes, copied from another place and say they tested it while in fact they have no idea what the codes mean or do.
