Question about T-Mobile Sidekick® 3 Cellular Phone

1 Answer

I bought a sidekick 3 off ebay but it is still locked to the previous owner's sim card number

I bought a sidekick 3 and planned to use it on the at&t network with an at&t prepaid sim card. i know it works, ive seen it done, thats not what im asking. what im asking is how can i reset everything on the phone? like when it asks for the sim unlock code the correct code is the one he created but he won't message me back to tell me anything. the phone is programmed around his sim card i guess and even when i do a network search like your supposed to in order for it to choose your carrier, it picks up my at&t sim but says it can't connect. Does anyone know what could possibly be wrong or what to ask about when calling customer care? thanks!

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.

Bought a sharp sidekick2008 cell phone from ebay usa imported to the uk suppose to be locked to tmobile when i put my tmobile sim in it request a special code to enable the sim can u help


You can call T-Mobile and inform them that you want to use the phone in the UK on their system - with your T-Mobile SIM card and they will more than likely either unlock the phone or provide you the 'special' code to use it in the UK.

Your other alternative is to purchase an unlock code from eBay. The choice is really yours.

I just bought a sidekick 3 from ebay. when first turning my sidekick on there is a message saying the sim card is waiting for activation or something or another. i receive and send text with no problems...


To be able to send pictures and what not with the sidekick 3 you need to have the sidekick data plan. That is part of the error message you are getting when first turning it on.Without it, all you can do is text and phone

3 digit combination


I use a sidekick Lx for At&t that I unlocked myself. When you start up your sidekick it should ask you for a network unlock or ask you to enable your sim card just click the cancel key on the top right of your device. Now click the top left menu button and go into your settings, and go to 'sim center' it'll ask you to enable your sim card again just enter a random 4 digit number and it'll tell you its wrong but thats ok, click ok and just cancel it out :) it'll then show you "disable sim lock" "change sim pin" change your sim pin to a number you'll remember because the way im showing you you'll have to do this every time you restart your phone (my sim pin was by default 1111) you can enter the same pin number for the old sim pin, and new sim pin options. Once you do that a white phone icon should appear on your screen underneath your time and date. Now, go back into your settings and go to network options, scan and select your network manually, and there you go :) Sorry though with all unlocked phones you'll only be able to make calls and text. No picture messaging sadly :( You need a T-mobile sidekick plan for all that :(

Cant get my sidekick to activate


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

I have a question?..


theyre right. it wont work for Verizon to use the full features on the sidekick. because, verizon and sidekick plan are totally different from each other. and only thing it will works for you that you can use the sidekick are sms(text) and to make a phone calls with a verizon sim card in and that pretty much it. 
and also, because a sidekick is restricted to tmobile. of course, but only things differently about it is the sidekick plan is only will works great for a sidekick itself that will definitely benefit you better to have/use the full features such as email, mms, notes, and etc. 

i mean, are you trying to use a sidekick with your verzion sim card in it or what? if so, then pretty much just like i stated right above.
sorry. :[

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
