Was wondering if any tmobile prepaid sim would give hspa plus to the galaxy Nexus?
Well that depends if your European version has 4G frequencies for AT&T or T-Mobile.
They arent the same, but then again it may have both, I dont know.
I havent taken the time to look up the technical specs on it, something you might try doing.
I know on both the Nexus One and Nexus S, there were both an AT&T and a T-Mobile version.
True, they were unlocked and would run on the other network, but would only run 2g, not 3g.
