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 :(

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


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.

Sidekick 3


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
