You can only do Voice and Text and Cingulars text packages suck.
Not sure how service is, do a personal coverage check

Everything but Vioce and text
the sidekick requires authentication with Danger's servers and without a T-Mobile account they wont do it. You can unlock any phone to work with voice, SMS and MMS but data is another story on this device
