I have an at&t sim card...I put it in my (att&t or Verizon networks)sidekick, and I forgot how to unlock it. Shift L? Or top left button and L? I know its L and something!

If the phone is locked to a particular network you will need to get it 'unlocked'. Depending on how new your handset is most good phone repair shops will be able to unlock it for a small charge.

Hi, let me straight about the meaning of unlocked phone. If your phone already unlocked from verizon network using blackberry storm 9530 unlock code, you can use any sim card on that phone. Which mean you can access data service, internet service or everything else only from your sim card network provider. So if you use an att sim card on your mobile phone, there is no way to download verizon web browser and why you need verizon web browser? Why you just not to use att web browser? If you still insist to download verizon web browser you can replace your att sim card with verizon sim card, then you can download that web browser on your blackberry and what is the point you spend some of your money for blackberry unlock code if you still using verizon sim card?

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 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.

from the keyguard lock go to emergency calls.
after that press the:

1. menu key (top left hand corner)
2. shift
3. q

Try this

1. at the same time hold the menu button (top left) and the jump button (bottom left)
2. This will bring you to the emergency screen (it gives you the option to make an emergency call)
3. Open to the keypad and hold in the menu+shift+q buttons at the same time.
4. The phone will reset and clear/unlock the security code

This works on sk3 i'm not sure about the skII.

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

ok dis is wat u have to do (i only tested dis on cingular or at&t waveva u call it)

1.your sim needs a password
2.turn off ur sidekick 3
3.place ur cingular card in
4.turn on sidekick 3
5.itz gunna ask you for a special code ignore it
6. go to settings den sim center
7. if ur sim lock is disabled jus enable it
8.den change ur sin pin to wateva you want
9.once u change it you will signals bars go up
10.go 2 settings network options
11. press scan scan select manually
12. select ur network
13. and datz it your sim iz workin on sidekick 3

if u turn it off u will have 2 do da same process again

soon i will put a video of dis on youtube

an easy way to make the phone work, but you can't text or access you sim but can make and recieve calls until you can get an unlock code is when it asks for the code, hit the big X button to cancel it out, then hit the upper left three lines button to bring up the menu. Go to settings, then network options, then scroll down to scan and select network manually. let it do it's thing and then pick Cingular or ATT sometimes one or the other shows up. And you can make and recieve calls with your number, I am still working on how to get the texting to work
