Sidekick 2 Iam trying to open a sidekick 2 so that i can put the sim card in .. how do i open it?? please help.

Your Sidekick operates on a GSM cellular network. Your Boost SIM card (and Boost Mobile phones) operate on an iDEN cellular system. You cannot use a Boost SIM card in a Sidekick. (FYI - SIM cards cannot be unlocked. Only cellphones phones can be unlocked.)

no ure done dude , unless you try to check main sim contact might be in there

go on google and look up WorldUnlock Code Calculator 4.4 and download it. it works on some phones i dunno about sidekicks. give it a try

Here is your solution: 
Now follow these steps to a "T" don't do any shortcuts etc, this is "across the board" for all sidekicks it worked on my Sidekick Slide and on my Sidekick 2008.

1. Remove battery and the SIM card from the devise.
2. Flip the sidekick open; press and hold the letter "r" on the keypad
3. While holding the letter "r", place the battery back in the device. DO NOT INSERT SIM CARD YET.
4. The Sidekick will restart itself twice. Please make sure not to let the letter "r" go until it has fully rebooted.
5. Once it has fully rebooted, remove the battery, reinstall the SIM card and battery.
6. Power up device.
7. Once the device has fully rebooted, all prior information should be erased from the device and it should be restored back to the default factory setting.

works for sk 3, slide and lx.
the video says only at&t in the U.S. but... i've seen it work for fones in europe.
try it.

I am having the same problem as of Saturday. T-Mobile can not help????? Something is going on with the east coast reception and after tech support had me do a few things my phone died. I am not sure what is happening but they are pushing me to upgrade at my own expense! Hmmm I am annoyed! If you get help will you please let me know! Thanks

Try to do a hard reset.


Flip open screen half way put pin or pen in the tiny hole and hold it in till it vibrate and turns off and on..


I hope it works

hello, hope these instructions help: 1. To expose the SIM card slot, peel back the bumper from the top-left edge of the device. (fig 1) 2. Insert the SIM into the slot with the gold contacts facing forward and the cut corner facing out. (fig 2) 3. When you release the SIM, make sure it is locked into position behind the catch so it will not spring out. 4. Replace the bumper and turn on the device. Any problems, let me know :) Si
