Hey guys does anyone know if the the new Nexus S will work on AT&T at 3G speeds? Thanks all
nope, it will work on Edge only
Maybe in the future like they did with the nexus one
Sent from my Nexus One using XDA App
as skunz said there is always a chance of an AT&T version, but for now T-Mobile 3G only.
They should... They did with the nexus one. I will wait, because i made the mistake of buying the tmobile one, then a couple weeks later the at&t 3g on was announced. haha
is ATT 3G better than TMO
I am currently on ATT with IPhone 4. Ready to dump the iPhone and get the Nexus S.
Should I wait for the ATT to come out? Is ATT 3G better than TMO? Why?
Thanks

Is your contract over? I'm guessing not You'll be stuck with EDGE (2G) on AT&T if you decide to get the Nexus. Wait a month or two, they should have an AT&T version in the works, hopefully

T-Mobile 3G is 4x faster than ATT 3G.
And wtf guys?
I'm pretty sure the Nexus S natively supports AT&T 3G:
Quad-band GSM: 850, 900, 1800, 1900
Tri-band HSPA: 900, 2100, 1700
http://www.google.com/nexus/#!/tech-specs
"AT&T uses the 850/1900 MHz frequency spectrum for 3G data"
"T-Mobile exclusively uses the AWS 1700/2100 MHz frequency-ban"
Here we have 850, 1900, 1700, and 2100.
This is full 3g for ANYTHING. Whether it's T-Mobile, AT&T, Europe.. blah.
Quad-band GSM applies to EDGE/Voice only. HSPA bands on the phone are what you need to be looking at when determining 3g capability.

Ah ic. Guess I'm wrong then. Facepalm.
It seems as though history might repeat itself. I would be willing to bet this phone will (or already does) exist in an AT&T flavor. I wouldn't mind taking a break from the iP4 for a bit, especially with this device. The reason I gave up my 3GS was for the N1, and it was groundbreaking and revolutionary. I don't know if I have the same thoughts on this device (because dual cores will probably be unveiled at CES '11), but nonetheless, this phone is and will be epic in it's own right, and always will be. I'm excited as hell for this device.
lets hope Sammy snuck the ATT 3G bands in like they did with the T-Mobile Vibrant
http://www.engadget.com/2010/08/22/confirmed-galaxy-s-unlock-codes-are-stored-in-your-phone-vibra/
That was the 1900Mhz bands, which AT&T USED to use for 3G. They're slowly phasing it out, and only some metros where they originally rolled out 3G still use those bands. They mainly use 850Mhz for 3G.

Am I right in thinking that if I see a letter H over my bars, that's faster than 3G. Like 3.5G or something?

I know the original vibrant was a pentaband phone, supporting AT&T's 850/1900 networks as well as t-mobiles 3g networks....
Can anyone confirm the 3g bands on the new Vibrant 4g?
Will there be fast 3g 21mbps for 850/1900 on the modem chip also? ( or 4g whatever you want to call it, in my book its just faster 3g..)
someone enter the debug screen and check which bands are available...

HSPA+ 21 only works with T-mobile, AT&T doesn't use an AWS band, in this case is 1700/2100Mhz.
Someone may have been able to 'trick' the vibrant into using a basic UMTS band on AT&T, but I never heard of it, let alone heard that the Vibrant supported AT&T 3G. The Vibrant has GSM.support for them (2G), I haven't seen anything else.
Where's the supporting documents that people have been getting At&t 3G with a T-Mobile Vibrant?

Trust me.... I'm using a vibrant on at&t with 3g. It does support the wcdma 1900 band. There is alot of evidence of this...heck engadget made a post about this... google it!
Edit: What I was trying to ask is if the galaxy s 4g supports the 1900 wcdma that the original vibrant supported....

That would work....hopefully the galaxy s 4g can be unlocked the same way the previous galaxy s phones could.
In my research I have found that 4G is not backwards compatable with 3G. Someware I read that companys are putting 3G and 4G chips on the new 4G phones to bridge the gap between the 3G chip ability to handle voice and the 4G chip being able to handle data. I can't say for sure if SGS4G has both chips. It's a know issue that the 3G SGS misses calls when connected to a laptop because It does not handle data well in combination with voice. That's why I upgraded to the 4G. I don't think Its going to make a lot of difference until TM gets their HW in place with a backbone that can support it.
Samsung Galaxy S 4G 1900 MHz WCDMA
I bought my Samsung Galaxy S 4G at a T-Mobile store in San Francisco. I subsequently upgraded it to the latest firmware provided by T-Mobile using Samsung Kies.
I usually use WCDMA only mode because GSM causes awful buzzing sound when I use it in my car (I have a FM transmitter connected to my phone).
Anyways, I was curious to see if I'd see AT&T, so I searched for network (still under WCDMA Only mode), and it found both AT&T and T-Mobile.
I pressed *#197328640# in the dialer, and then went to the debug screen/band selection to look at available bands, and it actually does have 1900 WCDMA.
It shows
GSM 850, 900, 1800, 1900, WCDMA 2100 (FDD I), WCDMA 1700 (FDD IV), WCDMA 1900(FDD II).
I don't know if AT&T SIM would work since my phone is locked but I can report back once I get it unlocked.
EDIT: Reading an old post of mine, I realized that my memory played a bad trick on me. My tests DID work on 1900 WCDMA and DID NOT work on 850 WCDMA, just opposite to what I wrote earlier in this post. --sorry

I don't think it would work. For reference, here is a side by side band comparison between my Vibrant (tested 3G on AT&T) and my coworker's SGS 4G (locked, untested).
The essential band here is the 850 1900 WCDMA, but the "overflow" 850 WCDMA is missing and I couldn't make it work anyways (I'm in Houston, maybe it is not switched on here).
My understanding is that AT&T usually uses 1900MHz for 3G, and in certain cities where they don't have enough bandwidth in 1900 MHz like NYC and SF, they use 850MHz.. so you could still get by with only 1900 MHz, no?

Yep, thats what I have heard as well. Now one thing of note. When I tested my Vibe, it only worked on the 850 1900 WCDMA band. Could not make it work on the 850 no matter how hard I tried. I'm in Houston for that matter and maybe this 850 WCDMA is not enabled here.

I'm currently unlocked on AT&T and i'm on 3G. I ALWAYS have an issue with upload speeds, but otherwise download speeds are just fine.
I attached four photos, of the available bands with my CURRENT galaxy S 4G unlocked on AT&T.
Also, a speed test I ran. That download speed is WAY higher than average because it was taken when the network was under the lightest usage possible, late at night.
Oh wow, over 5Mbps download on AT&T?
Are you on AT&T's 4G (HSPA+) or 3G?
I'm supposedly on T-Mobile 4G (my phone shows 4G when I download/upload), but I don't ever get 5Mbps. I get usually something around 2~3Mbps down and 1Mbps upload. I'm in the Bay Area.
I went into phone debug page, and one of the screens says HSDPA[0], HSUPA[0]. It also says network status: HSDPA (sorry I don't have the exact info on me right now).
Am I really just on HSDPA, not HSPA+? Is there a definite way to find out what my phone is using? Thank you.

Technically I'm on HSPA+, though this phone doesn't even cover all of the "necessary" bands.
Look, to edit what bands you're on go into the market and download SGS Tools.
Then, go into the first line (Secret Codes) and hit Band Selection.
I'm on AT&T so I'm not sure what bands you need, but you can manually select them in there.
To check the band you're on, go to GSM Status in the "Secret Codes" page again.

Oh I know I'm on 1700/2100 MHz because that's the only frequency (AWS) that T-Mobile uses for WCDMA/UMTS/4G/3G.
I downloaded Phono, and it says Network Type is HSDPA. Shouldn't it say HSPA+? I'm just wondering if there's an easy way to tell if I'm really on 4G (aka HSPA+) as opposed to 3G.
I actually messed around with debug settings last night so I'm worried that I screwed it up....
Thank you!

Which debug settings did you change?
And as for Phono (which I've never even heard of/used until now), my phone says HSDPA as well, which, quite frankly, makes no sense. I guess you can technically get speeds of around 5MBPS on HSDPA but it's not typical.
You should easily be able to tell whether you're on HSDPA or HSPA+ with the 4G/3G connectivity icon. in your status bar.
Now, I'm no expert, but hopefully that answers your question.
I played around with GCF settings. When I go into debug mode, there was something about choosing Rel.6 or Rel.5 or cancel settings.. And then also, if you do *#3214789#, you can enable/disable GCF Mode.. which I have no idea what it is about....
Thanks!

I put my friends att sim in my unlocked sgs4g to test and the 3g sign came up by the bars as well as the att operator logo didn't really test out speeds but im guessing that the 3g sign wouldn't have came up unless it was really picking up that frequency.

I regret to inform you that this isn't going to happen. You said you have an i9020t from WIND right? WIND uses the CDMA network. Rogers, telus, bell, (and many others) use a GSM network. If you put in the Sim your phone won't read it properly. I'm sorry but it looks like you need a new phone unless you want to risk swapping hardware and destroying your phone. Even if you did swap parts I don't think it would work ad well as you think .
As suggested sell your Nexus you'll get a fairly good price for it. You could buy a used i9020a after. Sometimes used ones can have problems though.. I say you should sell it and find a way to get a new one

Sprint is the only carrier that sells the CDMA Nexus. Wind uses AWS, which is 1700 MHz UMTS (3G GSM). The i9020t has AWS, as well as quad-band EDGE (2G GSM) for legacy networks.
As far as i can tell, if you want 3G, your only other choices are Mobilicity and Videotron. If those aren't available, Rogers is the only 2G GSM carrier I could find. Neither Bell nor Telus would be an option. They use CDMA for 2/3G and 1900 MHz for 3/3.5G.
This is, of course, assuming that your phone is SIM-unlocked.

From what I see here it looks like it only supports 900, 1800, and 1900 GSM frequencies. AT&T do use 1900 in some places, but 850 in most. So it looks like the phone isn't a great candidate for use on AT&T. T-mobile use 1900 so you might have better luck with them. However, it will only be 2G.

It saids LTE B1/2/3/4/5/7/8/12/17/18/19/25/26/28/38/39/40/41 from his listing.
But does tmobile use 1700/2100MHz is it band 4?
Just little afraid getting it from overseas in case no LTE with tmobile
Based on the supported bands it will work with most Tmobile bands except HSPA (3G) on the 1700 band. You will also not have WiFi calling or VoLTE on band 12 since it's not a certified device. You would be better off buying the tmobile note 5 N920T unless those things I mentioned don't matter to you.
