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

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 ?

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.

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.

E-sign = EDGE.

USA uses different bands from the rest of the world because, well, idk
North America:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41

Rest of World:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
This might be the case here, i don't think its carriers fault but idk really.
