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.
Does Tmobile Vibrant have 850 MHz 3G UTMS band?
Thank you very much!
I know Euegene has the band unlock on his R13/R14 roms.... so I would say yes, but I've never done it. I know this would allow you access to AT&Ts 3G.
I am with ATT now and would like to use Vibrant and its 850MHz 3G capability.
Euegene,
Could you comment?

No it doesn't. No one, not a single person has shown a Samsung Vibrant on 850MHz. It would be a shock of the Vibrant has bands it wasn't approved for by the FCC.
Id PM Eugene. He used to have the instructions posted on his thread. Check that thread also it may still be there. Oh wait Eugene said he's no longer giving support on XDA so you might go to his site which is linked in the Macnut thread.

There is an app for that. Download SGS Tools from the market. Select secret codes select band selection select gsm and 850 is an option.

Could someone confirm your Vibrant works on ATT 3G 850 MHz Band????
A screen shot would be appreciated!
I am about to buy this phone. Just need to know if 3G 850 MHz works with it.

I'm going to have a seizure... NO ONE can confirm that it works on 850MHz. It ONLY passed the FCC with 1900MHz 3G. People talking about "enabling" 850 have yet to show the phone ON 850MHz 3G.
This thread was started just an hour ago. It will take a little time for the few, admittedly if any, that can confirm to see this thread. I can only confirm that the 850 band is an option that can be selected. Whether this works or not I can't confirm.

One more day, please. I am delaying buying the vibrant for 1 more day.
Anyone out there got the 850 MHz 3G working on the vibrant?
Please prove it!!!!!!
I enabled the 850 MHz on my Vibrant just like Eugene's tutorial showed. I'm on a 850-ONLY 3G area. No 3G signal at all. Stuck on EDGE. Just like when it was disabled.
The 850 mhz band works on the Vibrant, but it is the 850 mhz gsm band not the 3g band.
^ pretty certain you get edge. I could have sworn eugene's thread said at&t 3G.... Because like some comments in here it made me sit back in my chair a bit and go, hmmmm

That's 850mhz 2G GSM. NOT WCDMA (which is 3g).
As heygrl stated, the Vibrant doesn't have the 850mhz 3g band. There are no FCC tests for it. There is no evidence that it actually works. The only reference to it is in that menu.
Really people, this has been discussed at great length.
Just search.
EDIT: you know, and I actually went back into my post history and dug up where I too believed that this phone had the 850mhz WCDMA Band.
In fact, I believe I was the first person to post about it in this forum waaayy back on July 28th.
http://forum.xda-developers.com/showpost.php?p=7382897&postcount=86
And as heygrl pointed out then - and after a very intense discussion - although the menu shows "enabled", the actual 850mhz 3g band never truly gets enabled.
Hello
I have the same problem here in Brazil. I bought a Vibrant from T-mobile and my carrier use 3G on 850 and 2100 Mhz.
If it's possible I would like to change the frequency on Vibrant or I'll change the carrier.

Can't say about Brazil but Hawaii
I did use att-3g on my phone in Hawaii and I did activate this. But, I do not know if my connection was because of this or not. But I do know that TMobile does not have 3g where I was.

Haev to agree, not to mention using a Vibrant to AT&T is dubious, anyways.
You can sell the Vibrant and come out at a profit by going to AT&T and getting a Captivate on contract. They're selling them for dirt cheap now - and you'll get better 3G and faster coverage (AT&T has upgraded almost all of its Network to HSPA+ as well, they just aren't advertising it).
I guess if you don't want a contract it can make some sense, or if for some odd reason you prefer the Vibrant build quality to the Captivate's (which is Superior).
But the Vibrant does not have that 3G band, and there was never a reason to put it in because T-Mobile does not Data Roam off of AT&T anyways (at least not anywhere around here).
I'm sorry if this is somewhere on the forum but I've searched here as well as do extensive searches on youtube and google and cannot get a solid answer.
My friend is stuck on AT&T with an iPhone 4 and wants to know if you unlock a MyTouch 4G can you get 3G speeds on it? The only reason we don't just get a full sim instead of micro and throw it in my Mytouch 4G is because he lives in an entirely different state.
any proof or just a solid answer with facts behind it would be appreciated, just trying to ditch an iPhone for Android.
MT4G supports:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
AT&T Network Provides:
AT&T’s 3G network listens for phones transmitting 3G traffic in the 850 MHz and 1900 MHz bands... so I'm thinking just 2G... the rest of the geniuses may provide more info...

With this info maybe you can find out what signal ATT 3G is using and get a match??
AT&T uses 850 and 1900 for 3g... which MT4G is programmed to use for 2G data... without some kind of radio rewrite or something way beyond my level you should only get 2g on AT&T.... same reason you had to get an AT&T nexus one to get 3g on AT&T
T-Mobile - Nexus 1
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
AT&T / Rodgers - Nexus 1
2G Network GSM 850 / 900 / 1800 / 1900
HSDPA 850 / 1900 / 2100
see the 850 and 1900 with HSDPA on AT&T and not on Tmo... that's why it no worky

this is what I don't understand, I've found video proof of the Samsung Vibrant running on AT&T 3G but it seems to have the same specs as the Mytouch 4G on the radio.
T-mobile Samsung Vibrant
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
I just don't understand how that works?

best way to find out is to go Nike on that beast.... (just do it)
Vibrant has 1900 band as well
so, you could get AT&T 3g in any areas that's using 1900
to my knowledge, the MyTouch4g doesn't have 1900 band
AFAIK, vibrant is only smart phone out right now that will do ATT and Tmo 3g
Sent from my HTC Glacier using XDA App
probably because samsung made the same phone 4 times... the two GSM phones probably have the same or very similar radio firmware.
Well guys, Im thinking about taking the plunge on this one. Im stuck on att right now and want a good android phone that has a flash camera so I have done my research and saw that the vibrant runs att 3g but lacks LED flash so im just going to take the plunge and get the mytouch and see what happens...
i can personally tell you that you wont be able to get 3g on the mytouch 4g. only edge (2g) via personal experience
the captivate will NOT use T-mo 3g the vibrant will use both....
and like i said i believe the vibrant is the ONLY smartphone (recently released) that will grab BOTH att and T-mo
d2 did you put up with the edge and use wifi as much as possible or go back to something else?

coming from tmobile's 4g to edge on att was KILLER. it was painfully slow. so i went back to tmobile.
yea thats what i figured, i have an iphone now on att and am used to being able to make calls on 3G and watch youtube videos, and if I get the mytouch all that goes away.
It won't work at all, you'll be stuck on Edge, and edge sucks, coming from a iPhone on T-Mobile with edge to the G2 then to the myTouch with HSDPA is like coming from a horse wagon to a Ferrari, and you're not going to like it at all.
Just come to the better data network and switch to t-mobile... maybe I'm spoiled I got a VZW and Sprint data stick in a cradlepoint router in my car and can do nav and WiFi calling when t-mo svc sucks...
Sent from my HTC Glacier using XDA App
T-Mobile's network has gotten so much better, its crazy to think how much the carrier race has flopped around. AT&T was at one point at the top of the list. Now they are the only network without 4G.
T-Mobile is the android network, we have the best phones and the best selection of phones. I agree with Eskimo you should make the switch.
switch?
Currently debating whether to make the switch over to tmobile. Going to purchase a mytouch 4g tomorrow for $250 new in box. Currently using a vibrant which was only $160, I unlocked it for a local carrier with 3g services. LOVE the screen! and the very very few custom roms. Coming from a nexus one I was spoiled with the roms.
Anyways stuck on this...Unlock the mytouch 4g and use it on my current plan, and sell the vibrant or go ahead and make the switch to tmobile.
Current plan:
500 minutes, unlimited text & data $55 with tax.... wife is on this carrier and majority of my minutes goto her.
Tmobile
500 mintues, unlimited text & data $59.99 plus 12% discount.....
pros 4g...and could drop internet service at home save $30 with 4g (can do simple browsing with 3g still)
cons...mintues to wife....
I don't even get 3g with my mt4g with tmobile where I live

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

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.

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?

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.

its much less confusing now. thank you so much. its looks like the tmo tech guy i called was ignorant and didnt know what he was talking about. again, thanks.
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.

hi tamasrepus... just to let you know, when i called the tmo rep like i told you in my previous post, he said that the SGS3 will use LTE.. but after your answers discredited him, i dont believe him. i guess we got to wait and see.

It did actually, AT&T and T-Mobile are gsm, while Verizon and sprint are cdma... completely different services. Your only choice is an AT&T, T-Mobile or a gsm international.

But LTE is a gsm technology, currently sprints/Verizons phone (Verizon razr maxx works on international/att networks after a recent update) is a hybrid, but they have weird lte frequencies, I've read that all US carriers will have incompatible freqs, but qualcom is building a chip that does them all plus European ones.

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.
Hey guys, I picked up this phone to test out a winphone a while ago and like it, but I'm having a huge issue.
I cannot get any network other than Edge to show up, and my speedtests are incredibly slow! On my Galaxy Nexus on Tmo's network I had to have the IMEI number updated somehow when I started my account, but it appears Tmo is closed today. Is there a way of doing this, or something else I need to do to get my Quantum to speed up, or is it hopeless?
It originally was an ATT phone that I unlocked to run on Tmo.

That's because AT&T and T-Mobile use different bands. AT&T phones are only compatible with T-Mobile 2G. If you're lucky, T-Mobile will be refarming spectrum in your area, so you can get 3G, but apparently this isn't the case for you.

Are you positive about that? I have a Galaxy Nexus that worked just fine once they updated the IMEI number, and now I have full use of Tmo's network on it. It was an ATT phone initially...

Galaxy Nexus: Supported Bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
LG Quantum: Supported Bands
UMTS/HSDPA Tri-band (850/1900/2100 MHz)
T-Mobile:
850 MHz/1900 MHz GSM/GPRS/EDGE/UMTS/HSPA 2G
1900 MHz GSM/GPRS/EDGE 2G
1700 MHz UMTS/HSPA/HSPA+ 3G/4G
1900 MHz UMTS/HSPA/HSPA+ 3G/4G
1700 MHz LTE
The Quantum supports the italicized bands.
The Nexus supports the bolded bands.
As you can see, the Quantum's supported bands are used for 2G.
That is unfortunate... so everyone else using this phone is using it on ATT's network, not Tmo's?
Also incredibly disappointing since I was told that the networks were the same and that a phone that worked properly on one would work on another...

Yes, most users are on AT&T. And as to your second point, I've never heard anybody say that...
I'll go ahead and bump this with one more question. With the announced merger between MetroPCS and T Mobile, is it safe to assume that MetroPCS' frequency spectrum will work with T Mobile phones? I believe I saw at least one band that the Quantum would be able to use.
I get Tmobile 3g on my Quantum, I'm in an area where they have 1900MHz coverage though.
