I have my phone unlocked but am trying to figure out was frequencies we can use for 3G on other carriers?
T-mo uses UMTS 1700 and 2100. But people who have unlocked and inserted a AT&T sim have been able to get 3G speed. Is the Vibrant able to get 850 and 1900 UTMS once unlocked?
It has 1900. In menu shows option for 850 also, but the hardware doesn't support it.

As said above, the Vibrant supports 1700/1900/2100 for 3G. AT&T uses 850 and 1900, so in 1900 areas, you can get 3G on AT&T.
In case anyone cares, the AT&T Captivate (AT&T's Galaxy S) supports 850 and 1900, so it will not receive 3G speeds on T-Mobile's US network.
The worst thing about t-mo network is that they require both 1700 AND 2100 to get 3g speed while ATT only needs one.

Not challenging you, just asking. How is TMO different than AT&T? I would guess that TMO is 1700 in some areas and 2100 in others, and so to get full coverage, you need both. Likewise, AT&T is 850 in some areas, and 1900 in some area, and to get full coverage, you need both.
Is this not actually the case?

No its not.
T-mo uses AWS(Advanced Wireless Services) which require both 1700 to upload and 2100 for download (or reverse).
On the other side of things... I would think that way of doing things (dual channel) would potentially be more effective

I think verizon would disagree on that.
Is it half duplex or full duplex? That would matter as far as having 2 channels for simultaneous upload and download.
The Nexus S supports these networks
Quad-band GSM: 850, 900, 1800, 1900 Tri-band HSPA: 900, 2100, 1700 HSPA type: HSDPA (7.2Mbps) HSUPA (5.76Mbps)

Telus supports 1900/850 MHz frequency bands. More detail at telusmobilityDOTcom/en/ON/network/about.shtm
BTW, AT&T and all other major Canadian providers use these bands.
Edge yes, 3G no
There are definitely a lot of people curious about whether they will release a rogers/AT&T band version. My guess is probably not, AT&T probably won't be interested in picking it up and it would be hard to justify it otherwise.
Ughh I really want to get one but no 3G on at&t is a dealbreaker

canada now has 3 providers using the AWS (1700) like T-Mobile. Wind, Mobilicity and (I may be wrong here) I believe Vidéotron
It will NOT work on Telus or Bell, period. It doesn't have the right 3G frequencies and Bellus doesn't have a GSM network.
Would anyone happen to know-
if I buy a Galaxy SII from Europe, would it work in the US? specifically with T-Mobile?
As I understand it, yes. But only with the EDGE network. 3G and 4G frequencies are probably different. Could be wrong.
This is the band T-Mobile USA uses: AWS, or UTMS. I don't think it would work, seeing the Galaxy S II's specs. I believe it has to be capable of both. I think best case scenario, it works like an unlocked iPhone and you can get Edge, but not 3G, much less "4G."
While the Galaxy S II supposedly works in both bands, I believe that in order to fully function with T-mobile USA's network it has to support both at the same time. Like I mentioned before, that's called AWS, and it seems to me it would have to be explicitly written in there as a supported band.
So what other carrier would support this device?
btw, thanks for the info!

At&t uses 850 & 1900 for data.
The SGS2 has 850, 900, 1900, and 2100.
It should work on t mobile, but I don't know the network bands off the top if my head.

I had to post because I saw alot of misinformation.
The GS II will certainly work in the United States.
It is a Quad Band GSM phone w/ EDGE data. It will also work on the 1900 WCDMA 3G band. At&t, Telus and Bell ALL function on the 1900 WCDMA band.
So yes the GS II will work with 3g on the 1900 WCDMA band here in the states and in Canada. You only need one 3g Band either 850 or 1900 will do. Best to have both so check your coverage area. I have a Galaxy S and have constant 3.5G HSPA signal with 1900 WCDMA only band.

I looked up the network bands. This is how it is:
Voice/calls/texts/etc. will work 100% fine on both of them.
As for 3G:
SGS2: 850, 900, 1900, 2100
AT&T uses 850 and 1900. 3G will work perfectly.
T-mobile uses 1700 and 2100. Apparently their network is retarded and you need both.
Sent from my Captivate.
Wrong again
T-Mobile uses 1700 paired with 2100 commonly referred to as 1700. A phone with 2100 will not work on T-Mobile... A phone must have 1700 to work on the T-Mobile USA 3G network anywhere in the USA. This phone will work on the 2G network and IF T-Mobile has any 1900 3G towers it could connect to those (I'm not aware of any at this time).
i know tmobile uses 1700/2100 depending on the area you are in and the galaxy s2 only supports 2100 out of those two. so my question is what frequency does tmobile use in nyc? or is it a combination of both?
Someone told me 1700 is for upload and 1900 is for down.
It supports the same bands the i9000 uses and that doesn't support 3g on tmobile

You need both. AWS uses 1700 to upload and 2100 to download.

not until t-mobile has completed refarming its 1900 frequency to HSPA+ ...at least for the international and AT&T models. im not sure about the Sprint version.
I heard that the Sprint variant of the S3 has a sim slot since its an international phone. All you have to do is root and unlock it and it should work on T-Mobile 4G.

That's not an accurate statement but it makes the point—non-T-Mobile GS3s won't work on T-Mobile's 3G/4G until they redeploy from 1700 to 1900 MHz.
T-Mobile hasn't put out a time table. AFAIK parts of downtown San Francisco (around the Moscone Center), parts of San Diego, and parts of Birmingham, Alabama (i.e. relatively nowhere) are the only places TMO has this configuration deployed.
That's not exactly true parts of Bellevue and Seattle Washington have been reformed too so I'm sure there's more areas

Look up t mobile 1900 mhz refarming. Thats ur best shot. Other than that right now signs are pointing to no hardware support for t mobiles currnt hspa bands. Basically, cross your fingers that tmobile changes to your frequency in your area with this phone. Tmobiles doin cuz they want to steal awayviphine users so they do have incentive. We'll be on that train too tho.

Yes, t-mobile uses the same tech, but is gimped as far as the 1900mhz band goes. Unfortunately there doesn't seem to be a definitive adviser as to when they will overhaul their services.

i'm a bit confused here.. maybe you, r3a1ist or someone can help. i called tmo and they said that the samsung galaxy s3 works on their 1700 - 2100 while at&t has 850 - 1900.
i'm really confused because on the tmo website, the specs for the SGS3 says that it works on the following bands:
tmo:
850 MHz;900 MHz;1800 MHz;1900 MHz;UMTS: Band I (2100);UMTS: Band IV (AWS);UMTS: Band V (850)
i got 4 questions:
1) what frequencies does the tmo version work on.
2) what are the frequencies that at&t uses for its SGS3.
3) what frequency does tmo use for its 4G (internet) network.
4) when LTE comes out next yr on tmo, will samsung release a new line of SGS3 specifically for tmo to work on its LTE?

Never, probably… I don't have a source (you can Google it) but T-Mobile does not have enough spectrum in NYC to do much shuffling.

The Sprint model apparently does not work. The AT&T may work later this year depending on your area. Are you asking whether you want to make a $500+ bet that it will? That's up to you—I wouldn't.

1) It works on the frequencies you posted. Let's rewrite that:
GSM/EDGE (aka 2G): 850, 900, 1800, 1900 Mhz
UMTS/HSPA+ (aka 3G/4G): 850, 1700 (aka AWS), 1900 MHz
Is it less confusing now?
2) AT&T uses 850 Mhz and 1900 MHz for their HSPA+ service.
3) TMO as of July 2012 uses 1700 MHz for most their HSPA+ service. T-Mobile will support HSPA+ on 1900 MHz in some parts of the USA by the end of the year. Very few areas (T-Mobile has only officially disclosed a tower near the Moscone Center, in San Francisco) do so now. Concrete details are sparse and nonspecific.
4) Next year is a long time—the SGS3 will be old by then, and the Galaxy Note 2 or SGS4 will have been announced. Nobody can predict the future. But, looking at the past, TMO released a new "4G" version of the Vibrant, so it's also likely they release new "LTE" versions of their phones.

one last question.. do you think that if i got the tmo version of the SGS3 and when LTE is released that the phone will no longer use HSPA? when LTE comes out, will the phone no longer use fast internet?

Yeah… that's a complicated question whose answer I don't yet understand myself.
TMO is doing their 1900 MHz refarming to free up 1700 MHz for use w/ LTE. Stuff I'm wondering:
What happens to older 3G/4G devices that don't support 1900 MHz? Do they lose their 3G/4G Internet? Note: the GS3 supports 1900 MHz, and does not have this problem.
How is TMO going to deploy in spectrum crunched areas (like NYC)? They don't have enough spectrum to move everyone over to 1900 MHz—does this mean 1700 MHz HSPA+ will be cut off when they bring 1700 MHz LTE online? Your non-LTE GS3 might lose 3G/4G Internet in this situation—but I doubt TMO would do this to anyone with a phone still in contract.
All in all, make your purchasing situation on the situation today. The next new thing is always around the corner.

It's simple, T mobile phone works on At&t HSPA but not LTE. At&t phone works on its own HSPA and LTE but not T moble 1700 HSPA. We've been trying to see if we can make it work on t mobiles 1700 hspa band, no luck yet. To make matters more uncertain. T mobile says they're refarming their 2g/edge spectrum to work on At&t's 1900 HSPA band. The At&t phone out of the box would be able to pick up this 1900 HSPA t mobile refarm. Although reports of this actually occuring are sporadic and they also fired the CEO who's plan it is a couple weeks ago. LoL. If you get that, that's the complete break down. So here you go:
T mobile phone - Supports both T mobile and At&t HSPA 4g speeds, no LTE of any kind.
At&t phone- Supports At&t LTE and HSPA only right now, t mobile HSPA "may" be available for it's antenna's in the future.
