[Q] 2g 3g 4g Speeds in the US with European SGS2

---

Hi folks
I just moved to the US (about a week ago) and was wondering why my mobile internet connection is so slow.
I have a SGS2 factory unlocked and i was fine with it in Germany (no problems with 2g or 3g speed)
Now I'm in the US with a t-mobile prepaid card which should give me 3g speeds , if not 3g at least EDGE Speed. But the only thing i get is the E-sign with 2 arrows which is friggin slow.
As far as i know t-mobile's 2g & 3g frequencies should be the same as in Europe.
So my question: Is my phone the problem or is it just that the 2g/3g coverage in San Diego is so bad ?
thx in advance

its normal...coz sgs2 does not support t-mobile 3g bands....but it does support at&t 3g bands....i am also using t-mobile prepaid plan...and dont use data that much...coz everywhere i go i have wifi....

ah ok thx for the reply
do you happen to know if an factory unlocked iphone (without sim lock bought directly from apple) will be able to use the US-3g bands as well as the European ones ?

as far as i know....it will be same as sgs2....only supports at&t 3g bands.....no t-mobile.....

Ok thx man.. Guess I gotta ask them directly then

Asking who directly? T-Mobile USA? You can ask, won't change the answer. If you want 3/4g in the US with either a European Galaxy S2 (GT-I9100) or an unlocked iPhone, you will need to be on AT&T.

T-Mobile doesn't use the frequencies that those two phones support.

E-sign = EDGE.
