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

You need unlock codes to unlock your Sidekick ID. I unlocked using codes from www.theunlockspot.com. I got the codes within an hour.

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.

Go to http://digitalgoods.synthasite.com you can purchase privacy unlock and network unlocking codes for the sidekick id and other sidekicks. Great site! I bought one! :) They are more expensive on Ebay its cheaper on that site.

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.

Sadly you cant actually unlock the sidekick as it is a T-Mobile specific device so hannah you've probably just wasted your money on a device that you cant use and Mwillip it sounds as though you're having troubles using the sms service in the states contact T-Mobile to get help with the settings.
