you should be able to press the button on the top left corner (has three line things) then press the letter "L" ... hold for a few seconds and the screen will be unlocked.
after the screen is unlocked you might need to go to settings (the top left corner button with the three lines) then network to manually select your own network... i have att and it didnt make me do this but hope that helps.
In order to unlock a sidekick, you must know the persons pass code, type it in, and then it will unlock. I have also heard that for the 3 Sidekick 3 and or 1 and 2, there is a glitch. If you don't know the pass code then all you have to do is press the 4 main buttons on and poff several times quickly. Hope this helps!!!!!!!!
you must call your t-mobile customer care and ask for the special unlock code but you must be a costomer for atleast 2-3 months. once you get the number you put the sim card that you want to be in there and its going to ask you for the special code. youenter the special code and it willconnect to the sever that you want
