Well, in most cases yes, as all 3G SIMs (USIM) I've seen have been valid GSM SIMs. i'd expect that to be some requirement even :)

OTOH there are carriers that are UMTS only (they don't have a GSM network), e.g. 3 in Austria.

I have a question about SIM cards.  If I have a 3G phone with its 3G
SIM, will I be able to put that SIM in the Neo?  My carrier is AT&T in
the US.

I think the answer is yes, because AT&T is having their old Cingular
customers upgrade to new 3G SIMs to put in their phones even if
they're 2G GSM phones (the 3G SIMs are supposed to be better at
choosing between Cingular and AT&T towers).  Can anyone confirm that
it'll work with the Neo?


"In science it often happens that scientists say, 'You know that's a
really good argument; my position is mistaken,' and then they would
actually change their minds and you never hear that old view from them
again. They really do it. It doesn't happen as often as it should,
because scientists are human and change is sometimes painful. But it
happens every day. I cannot recall the last time something like that
happened in politics or religion."
