Loading problem? I just a sidekick 3 unlocked brand new from a friend.. and when i put my att sim card in there.. its telling me it can take anywhere from 1 hour to 48 hours to load and activate the phone.. Is that what they all do? please someone let me know..

More than likely your contacts are still located in the old phone. Replace the Sim card back into the old phone and copy the contacts onto the Sim card, place back in your Sidekick and you then can locate your contacts.

try pressing menu (the three bars) and L at the same time. i had an at&t sim card too and that worked.

So an unlocked Sidekick on ATT will only be able to do text and phone. The other sidekick features require the t-mobiles sidekick data plan. It is hard coded to the phone

That is the only way to unlock the PUK,Just Call and tell them you need the PUK code and read the number off the sim card to the customer care person when they ask for it.

Your going to have to call customer service. Thats what my dad did and they unlocked his phone. (:

Go to att.com log in to your account and under phone devices there is a link to obtain a puk code but it has to be entered using Att phone. That was how I unlocked my sim card.

this is what you do:
you have to call at&t and tell them what you are doing they will give you a code for the fone, but you will not be able to send pictures, email, recieve pics or anything..well that is if the sidekick is compatible with the sim card, because on the box it says it is not..GOOD LUCK!!

I found this guide online.
Please let me know if this works!

"1) Insert the ATT SIM card into the back of the T-Mobile Sidekick ID (it should be located behind the battery).

2) Turn on the Sidekick ID, wait for the screens to load.

3) When the screen says "Waiting for Activation", hold the top left button (the "Menu" button with the three lines) on the Sidekick ID and hold the letter "L" on the QWERTY pad at the same time. After a few seconds, let go of the buttons.

4) If Step 3 is done correctly, the Sidekick should be directed to the jumpscreen and display all of the Menu's of the Sidekick ID.

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

ok the way to do it this jus lets u use text and calls i got cingular and i used my sidekick to txt and call here wat u gotta do

1. out sim card in
2. start phone
it will tell u sim card locked it needs special code(the code u get to pay for) juys exit outta that get to the main menu
3.hit the top letf menu button and go all the way down to sim center if u dont allready have a sim pin then enter a new one if u have one change it then ur phone should go from the big X to some bars and a hollow phone icon after you do that hit the menu button again and go to network options then go down and hit (SCAN AND SELECT MANULLY) then chose what ever carrier you have i have at&t so i chose it after a few seconds the hollowed out phone icone should be colored in and u can now text and call
