Hey. I own a Sidekick and I'm from the Philippines and you actually can use it anywhere, I figured.

1. Place the SIM Card and open the phone. A window will immediately appear demanding for your SIM PIN. Just press CANCEL.
2. Press Options/Menu or whatever the 3-horizontal bars on the upper left of your phone's called. Go to SETTINGS, then SIM CENTER.
3. Press Unlock SIM CARD
4. If you have a SIM PIN Code, type it. If not, just type 1234. then ENABLE. T he code won't be accepted. Press CANCEL.
6. In the Old SIM PIN, type your PIN. If you don't have one, just type 1234 again. Type 1234 for the other 2 questions.
8. When "Waiting to register...." appears, all at once press OPTIONS, Letter L and that key on the lower right of your phone.
9. Exit
10. Go to settings again. then NETWORK OPTIONS
11. In the NETWORK SELECTION, press SCAN AND SELECT MANUALLY. Your phone will look for networks and when it's over, press DONE.

I dont know if this can help you but heres a simple tip. turn on your sklx with your sim inserted then wait for the phone to ask you for the special code. Cancel this twice.Then go to settings and sim center. go to change sim pin. put in a default number like 1234. then enable. you will see the emergency screen.. press menu then call and text. go to settingsthen network options. select network. Wait until your sklx find a suitable network for you then eneble.. I hope this can help you with your problem..

Phone request me to enter the sim code when i used Cambodia's SIM

not sure if this works with the 2008 but its something you can try, i put a sim card in my LX and was asking for a special code to unlock the phone, well right now tmobile isn't unlocking the sidekick, but you can trick the phone into using the sim card. First go to your settings, go to "SIM Center" and click on disable sim lock, enter in whatever your sim password is (if you dont know your sim password get your PUK (pin unblocking key) number which customer service will give you if you call 611, you can change that SIM pin by typing **05*PUKnumber*newpin*newpin#) now if you wanted to change it to "0123" if your puk was 9483992 its 7-9 digits you would type **05*9483992*0123*0123# now your sim pin is 0123. (trying not to make this super complicated) it will say sim pin not accepted click ok, now click change sim pin you can type the same sim pin 3 times if you want, 0123 0123 0123 now at the top of the screen bars will show up with a white phone beside it, go to Settings-Network Options-Scan and Select Manually, the SIM network should come up, click ok when it finds it and it will connect, now you can call and text on whatever sim you have in the phone

The special sim code for the sidekick lx

just ask the phone company provider for your PUK2 AND PUK codes.
when you get them go to the jump menu dial
the passcode is any 4-8 digits you'd like, that are NOT, AND I REPEAT N - O - T consecutive.
(for example 2736 is good whereas 1234 or 9876 is bad)
if it asks your for the code again put in the PUK2 then go to settings> network options goto the "scan and select manually" button and chose your carrier.
