I have tried that, after pressing the code it displayed all the network of the phone but when I select 3g it did not come up, rather edge came up

Star ash 2 2 6 3 ash, select wdcma only. Cheers

The code is not displaying anything, it says invalid code

Are you sure this is an original Samsung phone?

My brother am totally confuse o, I have tried a lot of code to test for it authenticity, some of it respond while some did not respond, please give me some Samsung master codes, for me to verify the phone

Mine is at&t too although it's not note2 but that shouldn't matter... and u don't get any option to change the network mode, don't know why so I use the code I put up dere and dis should happen when u dial the code

Sowie it's star ash 2 2 6 3 ash, my bad

I tried the code, it displayed all the network but only edge is working all the rest is not working.

Select wdcma all, that's the last option, not the first one u selected.... The star in the bracket from the network mode indicates what option ur currently on, compare mine and urs
