PLEASE HELP! i have a t mobile nokia phone, & was planning to purchase a sidekick 2 on ebay. can i use the sim card in my nokia phone in the sidekick 2?

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.)

press menu + L at the same time to bypass this screen. This will continue to come up every time you start the phone. by default, it wasn't the t-mobile sidekick data plan and always searches for it on start up

Let me start by saying I'm not an expert, but after going through a lot of gyrations I came up with a solution that worked for me. I'm sharing it here because I haven't seen a complete concise answer anywhere.
The activation problem with Sidekick Slides is common. Most of the time, people buy a Slide without realizing that you have to purchase a "sidekick plan" from T-Mobile to get it fully activated. These phones were build especially for T-Mobile, so they're designed so that you have to have a Sidekick rate plan first to get the phone activated. By the way, this applies to a new phone as well as a phone that's been activated before, but has been 'hard reset" (where you hold the R button while re-booting.. My advice, DON'T DO THIS! Because you have to re-activate the phone.
However, there's good news for all you non-T-mobile folks who bought a Slide on eBay (or from a friend etc.) only to find it needs activation. Here's the solution. If you search eBay for "sidekick activation" you can find folks selling prepaid activation kits for around $15. They include a sim card and about $10 worth of sidekick prepaid services. Buy the kit, install the sim, and go online to register your phone (registering by phone is a pain with T-Mobile). Online you have 3 plan choices: Pay By The Day, Pay As You Go, and Sidekick. Pick Sidekick, and then provide the requested registration information. When done, your phone should be ready to go and should activate within about 5 - 10 minutes. You'll be charged $1 a day and airtime for calls, so it's not cheap, but at least the phone won't go to the activation screen when you startup.
The next question is, how to unlock the phone for other networks? IF it's not unlocked you will be prompted for special code (this is different than the user-defined password that simply locks the phone against unauthorized users). It won't work on other networks until it's truly unlocked. Again, the trusty folks at eBay can help. I searched for Sidekick Slide Unlock Codes and found numerous vendors, ranging from $6 to $12, who provide permanent unlock codes for Slides. I found on that provides the code via email (others want to mail it to you) and got my code within 30 minutes. So now I can remove the T-mobile sim and put my ATT (or other) sim in and go. I should mention that some of the Sidekick features ONLY work if you have a sidekick plan, but that's T-Mobile's and Danger's devious attempt to make us miserable. Good Luck! Hope this helps! Rick

Hello.. I live in denmark and I just got the sidekick 2008.
I bought an Isim (ver. 2) on ebay. I payed $9.
Then I put It under my non tmobile sim card and powered it up and I could se my phonebook and other stuff from my sim. But it keept saying: emergency calls only.
Then you have to put it into a nother mobile phone to get signal. Then put it back in the SK with the Isim and then it works. Just remember to update the sim and phone with the settings from your current phone company by sms. Then it wont happen again.

It worked for me. so I hope it would help others...

I had the same problem with the sidekick i bought off of ebay , when you cal customer care just tell them you got it off ebay and you need the old users information deleted, they will give you step by step instructions on how to do so. Remember to not call on your sidekick becasue you will have to restart the phone.

you might want to try a soft restart by holding the "@" button, 1, and 0 all at once. it usually helps

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.

Yes you can, But you will have to get an unlock code to unlock the sidekick so you can use the sim card.

=).

1. Insert your non-TMobile sim card 2. The phone display says "Enter the code". 3. On your Sidkick, press the "X" button. 4. You will see the menu. 5. Choose the left-up angle button. 6. Choose "setting"--->"network"--->"scan and select manually". 7. The phone will search for your network. 8. When your Sidekick finds your network, you can use the phone to make calls

with other sim cards you cant use data services...t-mobile uses different type of connection from other companies

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
