Your Samsung u600 wont unlock-how do you get it to definitely unlock?

Answer 1

There are various method to permanently unlock your Samsung U600.

You can go to your provider. After 1 year this should be free! If this is not the case you can still do it but they will ask a lot of money for this in some cases.

Second option is going to a unlock store near you. Problem here is that you don't know what happens with the phone there is a lot of free half working software around which can damage your phone

Third option is using free unlock codes such as:

*2767*3855# and then:

Disables CP lock : #7465625*27*00000000#

Disables Network lock : #7465625*638*00000000#

Disables SIM lock : #7465625*746*00000000#

Disables SP lock : #7465625*77*00000000#

Disables Subset lock : #7465625*782*00000000#

but be VERY carefull as they can damage your phone (no reception or 'phone freeze' or 'contact operator service' message.
You can permanently unlock your U600 very easy using the usb cable that comes with the phone.
