Incase you haven’t purchased your unlock code yet then CLICK HERE TO BUY YOUR SIDEKICK UNLOCK CODE
Else follow the instructions for the model you wish to unlock
For All SideKick Models :-
Insert a SIM card from a different network provider and turn on the Sidekick. A dialog screen comes up, prompting you for the code.
The box will say:
Title: Special Code Required
Dialog: Enter code to enable SIM
Box for Code: 1-8 digits
Options: Enable or Cancel
In the upper right hand corner, the SIM is flashing where the signal strength should be.
On entering the code, a dialog box comes up saying authenticating code. It’s unlocked. Enjoy.
In case you see the ‘Waiting for Activation Screen’, hit the menu key and the letter L key at the same time. The menu key is the top left key. By doing this, the waiting screen will go away and you will be able to make calls. For best results, hold down Menu and the L key until the Waiting for Activation screen disappears.
Please Note: You may have to repeat this procedure again if your phone is turned off or your SIM card is removed.
