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

Used Sidekick


Call your carrier and ask them to detach your device IMEI from the username locked in. Once that is done, hard reset without your SIM card inserted

My sidekick id


Try a master reset.

1. Remove the battery and the SIM card from the device.
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 THE 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, re-insert the SIM card and battery and power up the device.
6. Once the device has fully rebooted, all prior information should be erased from the device and it should be restored back to the default factoy settings.
