You can Unlock the T-Mobile or Sidekick ID there.

Give this a try.Enter wrong pass for more then 5 times,it ll ask u to enter the puk number....now call t mobile (150) and get the puk number...enter the puk number in the space given for pass....thats it...problem is fixed
if u had locked ur mobile then update the formware all saved passwords ll be deleted.

Unfortunately, T-Mobile cannot or will not unlock the Sidekick devices. This means that if you want it unlocked you will need to pay for it. There are third party companies and programs that claim to be able to unlock these devices, as you know most cost money. Sorry I couldn't be of more help.

Nope, the you need to pay someone to unlock it for you.

or you can use a special sim card insert that allows you to unlock it.

Unlock Sidekick ID

how can i unlock my sidekick ?

I found this guide online.
Please let me know if this works!

"1) Insert the ATT SIM card into the back of the T-Mobile Sidekick ID (it should be located behind the battery).

2) Turn on the Sidekick ID, wait for the screens to load.

3) When the screen says "Waiting for Activation", hold the top left button (the "Menu" button with the three lines) on the Sidekick ID and hold the letter "L" on the QWERTY pad at the same time. After a few seconds, let go of the buttons.

4) If Step 3 is done correctly, the Sidekick should be directed to the jumpscreen and display all of the Menu's of the Sidekick ID.

Please help me with unlocking sim card
just insert the sim and it said "enter the special code" IEMI number : 355564012471427 Device : T-mobile Type : sidekick slide Hope any one can help me for this? If anyone know how to unlock it or the unlocked code just send me to my email: [email protected] VERY VERY APPRECIATE THAT!

Try holding down Menu-jump to get to the emergency screen. Then hold down on menu-shift-Q and release. It will ask if you want to reset phone. IT WILL RESET AND DELETE EVERYTHING!!!!. It will be like new. Except sim. This works with sidekick 2, not sure with others.
