    AT&T is on a GSM network which uses SIM cards, while Boost operates on Sprint's CDMA network, so the answer is NO.

    I had a similar question. i have an active boost account with walkie talkie feature which operates on sim card.
    Dont mind loosing the walkie talkie feature. . . . think theres any possibility?

    can a Pantech CrossOver w/att be flashed to work on boost sim?

    As far as I know, AT&T phones are not compatible with Boost/Sprint service...

    YUP. Never known anyone that has had one that's been converted. I have heard over and over that it cannot be done.

    AT&T is on the GSM band.

    Sprint is on the CDMA band.

    Completely incompatible. There are some CDMA phones that are GSM compatible... they are mostly sold by Verizon and marketed as "world phones". But you'll never be able to put a GSM only phone to CDMA.

    Your best bet? Get a sim from Straight Talk. When ordering make sure to mention that you want a AT&T chip. $45 a month "unlimited". Just dont overuse their data.

    Good luck.

    boost with no sim runs on CDMA I believe at 1800mhz

    boost with sim runs on iDEN and i believe is at 700mhz

    GSM is a completely different network, so sorry no go there.

    AT&T is a straight GSM network. Their phones are completely incompatible with the Sprint/Boost CDMA network. You could probably get it hooked up with the Wal-Mart T-Mobile Friends and Family service though.

    ThNks to all that posted.
    One last Q.
    Can verizon phones be flashed to boost?

    Not really... Most of the Sprint phones for Boost that you see on Ebay and other sites weren't cleanly flashed (clean E.S.N.'s, etc...) Technically, Boost doesn't allow flashed phones on their service, so it's highly unrecommended. Having a phone "legally" flashed to another carrier such as Metro or Cricket isn't always foolproof that all of the new carrier's services such as S.M.S., mobile internet, or M.M.S. will work on the phone either

    Too much headache. Not worth the trouble unless you find a forum that'll cater to the problems and suggest solutions. Since it's illegal that's kinda iffy too. You'll constantly run into problems and have to look into solutions. Just wait a bit longer and Boost will offer a fancy 4g phone soon. From what I hear/read July 2012.

    If that's too long of a wait then try Straight Talk. From your previous post it seems that you already have a AT&T phone. Ask for a AT&T sim from Straight Talk and put it in and go. $45 a month, unlimited. Their network also has a larger footprint than Sprint/Boost.
