I bought a T-mobile sidekick and im through AT&T. When i put in my SIM card(AT&T) The sidekick wont let me make calls or text, but it asks for a security code?? I heard you could unlock t-mobile phones and at&t phones vice versa?

Can anybody relate or help me out on this situation.
thanks.

you can unlock pretty much any phone that is GSM and you can flash any CDMA phone to another carrier(other than to sprint).

there is a way to unlock the sidekick, blackberry, etc. but you'll have to find out how. if you look on your local craigslist there are ppl that can do this for you at a small charge. i am one of them ppl but it's too complicated to describe here. you also risk killing your phone if you dont know what you're doing.

Call T-mobile Tech support and tell them that you are leaving for a foreign trip or something and you need the unlock code 4 the phone, At&t happily gives the codes too you, i think t-mobile will too. But be sure to ask tech support the question, and not any other representative... Hope this helps

Hi, yes i agree with you both AT&T and t-mobile locked phones can be unlocked and freely used with any GSM sim ...Your sidekick wont ask for security code it might ask network unlock code once you insert AT&T sim because your phone is already locked with t-mobile ..you can easily unlock your sidekick mobile with MobileUnlockSolutions.com this unlock provider helps you to unlock your phone with very reasonable cost.
