I have a tmobile sim card and I'm wondering if it would work on an unlocked Galaxy S2 that's available from amazon. If not, would a boost mobile prepaid sim card work? I live in the U.S. by the way.

Yes, an unlocked phone will work with any carrier. The sim lock is something that limits the networks the phone can work with, not something that limits the phones the sim card can work with. It is usually just there so people don't get a dirt cheap subsidized phone and use it with another network, or so people don't get a new prepaid sim when in another country to avoid roaming charges.

Before you go out and buy this, I would do a search here. I have some recollection of reading that the SGS2 didn't work with T-Mobile in the US.

Until I read that, my understanding was the same as Baschi's but at least someone here doesn't agree so do have a look before taking the plunge.

[Edit]
Here is one post implying it won't work http://androidforums.com/samsung-galaxy-s2/366901-does-version-1700-2100-mhz-hsdpa-band-exist.html#post2898027 and here is another http://androidforums.com/samsung-galaxy-s2/365822-3g-4g.html#post2894817.

In short, I know naff all about who uses which part of the spectrum in the States, but if these posters are correct, I would excercise caution before buying.

T-Mo uses different 3G bands so I do not think you will get 3G services. Yes you will have phone and basic Internet but lack some speed on same.

My brother bought one. The phone will make calls, but internet connection is only Edge. Super slow. T-mobile said it's because of the band difference.

T-Mobile is AWS and there is no AWS band version of the phone I want it for Mobilicity here in Canada (T-Mobile uses same bands)
