[Q] Anyone using the Omnia 7 in the US on AT&T

Is anyone using the Samsung Omnia 7 on AT&T? I know it has support for AT&T's 1900 band for 3G but wanted to know how the experience is. I'm in Germany this week and was hoping to see if I can pick one up [not really happy with any of the AT&T phones].
Also, with updates possibly being controlled by carriers what's the workaround for buying an unlocked device from overseas and using it in the US on AT&T?
Thx!

can't tell you about omnia on at&t, but as far as i'm aware if your phone is unlocked from carrier, i don't see any reason/possibility for them to delay an update being rolled to your phone.

Cool, thx.

You should be able to get updates via the Zune software.

I'm sorry. this is my first post for this forum. Im not educated on on the compatibility of the EU phones on US carriers....
But is this really possible? I really like the SS Omnia the best so far.
an unlocked ominia will work perfectly fine on AT&T?

it will work perfectly.. except for the lack of 3G. The omnia lacks the all important 850 band at&t uses... and the 1700 band tmobile uses.

An explanation for "The omnia lacks the all important 850 band at&t uses" would be useful as AT&T also supports 3G on the 1900 band that the Omnia 7 supports. So seems like it should work...

Thanks for that response. I really wanted to see if I could sneak away with the omnia as the focus isn't really as good

One advantage with the Focus is it has an SD card slot to extend storage.
If you use you phone for music,movies and games it's a big +.

lacking 850 is not a problem since only mayor citied like new york, san fran, dallas etc. have 850 and the majority of normal city only have 1900. so 1900 is fine given you don't have access to hsdpa and hsupa, only regular 3g. now if only i can find an unlock omnia 7 under $650.

There are maps available showing coverage for each AT&T 3G frequency band. I wouldn't dismiss one band over the other. It all depends on what city you live in.
Check into the coverage areas before you waste money on a phone that won't give you 3G coverage in your area.

Very interesting as I googled AT&T 850 vs. 1900 MHz Coverage and pulled up a very interesting map [can't post a link due to my post count].
Coverage of the two bands is almost identical. I didn't know that speed is something to give up on the 1900 band though.
Good info. Yeah, I'm in Europe this week and no one is offering it unlocked!

here's the maps.
http://www.cellularmaps.com/att_850_1900.shtml
my question would be though, which is the band they are going to expand going forward???

so what's the difference between these bands? the phone does both so you would be "covered" so to speak

I'll be asking at an AT&T store, perhaps they can shed some light...

i personally am not sure if all phones handle the varying bands straight from the OEMs. HTC lists what bands their phone supports to each region, but in saying that it would be good to know what would happen if you got a omnia to the US (or in my case if i somehow managed to get an unlocked focus to australia ).

I don't think the phone supports at&t's 850mhz band.

according to this it does
http://www.pdadb.net/index.php?m=pd...icially_confirmed_windows_phone_7_smartphones
and this
http://www.gsmarena.com/samsung_i8700_omnia_7-3537.php
GSM850, GSM900, GSM1800, GSM1900, UMTS900, UMTS1900, UMTS2100
CSD, GPRS, EDGE, UMTS, HSDPA, HSUPA
From what i've heard, ATT doesn't even really use the 850 spectrum much anymore...

Several people are selling this new on eBay for ~$600, but it does not support 3G. As per the one auction details:
* Works with AT&T and T-mobile EDGE but does not work with 3G networks in the USA
* Works with AT&T 1900Mhz 3G but not AT&T 850mhz 3G - Does not work with T-mobile 3G in the USA
I love the design of this phone too but is it worth paying all that money for a phone where you won't be able to take advantage of all its features? Edge is slow as Sh*t compared to 3g in my area. Just consider that if you really want this phone in the US.

[Q] Nexus S AT&T 3G?

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?

[Q] Samsung Vibrant 4G SPECIFICATIONS

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...
cheers!

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?

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 mean, if the phone is that messed up since you messed with that setting.

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.

It will work, but you won't get 3G... Only EDGE.

What is the status of this? If I remember correctly the G2x specs initially listed full compatibly with ATT's data networks, but attempts to make it work were fruitless.
Is there a chance (no matter how slim) that an updated baseband could enable ATT 3g data, or does the hardware truly not support it?

The hardware does not support it. T-Mobile said it was a mistake in the promotional materials but with so many shady things about the way the G2x has been handled, I wonder if it was done on purpose. Part of the reason why I went G2x was because it was AT&T compatible. I wouldn't have had to get a new phone should the merger get approved.

It seems to be an issue with the baseband chip. The 2X uses an Infineon baseband chip and it could have supported 850, 1700 and 2100 (tri-band 3G can be configured for any three bands - optional five band 3G version is available) but the top data speed is 7.2Mbps. On the G2X LG switched to a Qualcomm baseband chip that supports 1700 and 2100 but has a top data speed of 14.4Mbps (also supports quad-band 3G on 850, 900, 1900, 2100 but the AWS version needed for T-Mobile band support is only dual-band). Maybe initially they were going to use the 2X chip but T-Mobile said give us faster data so we can lie to our customers and call it 4G.
For geeks who want to know the 2X uses an Infineon X-GOLD 616 PMB9801 and the G2X uses the Qualcomm MDM6200 baseband chip.

Using mine on at&t...I don't pay for their outrageous data plan so I can't comment say if 3g works or not (I don't see any 3g notification on the phone), but it does work other wise. Who needs a data plan when you have wifi every where you go? I use a wifi app for texting so I'm not sure if the messaging/picture messaging works, but if someone really wants to know I will try a friends sim card....

You gotta be kiddying me man. Seriously you wanna put this phone on ATT and have all those limitations? Go with tmobile. Awesome service!

AT&T is buying T-mo spectrum to kill it and use it for LTE. They're keeping their 850/1900 for 2g/3g. The G2x won't work on their network for 3g, neither will 99% of the other T-mobile phones. They won't keep running the 1700/2100 T-mo 3g frequencies for any decent amount of time. Its in their best interest to have all customers running on one set of frequencies.

[Q] Intl XL and X ATT - are RUU & radio interchangeable?

Since this model isn't out yet, I suppose this is not yet considered a n00b question. I am, and I'm sure many of you are also, wondering if the international One XL and the US version One X on AT&T would be able to interchange radios via RUU updates. If radios are interchangeable by themselves, is it simply a matter of S-OFF?
Why am I asking this?
I'm on T-Mobile right now, planning to use AT&T model with TMo's HSPA+, but then I am moving to Europe in a few months - in Germany, they're using LTE on 2600 MHz whilst UK is rumoured to be using LTE on 1800 MHz (though LTE there is now up in the air again).
Safe!

ATT bands:
LTE CAT3 - DL 100 /UL 50
LTE: 700/AWS
WCDMA: 2100/1900/AWS/850
EDGE: 850/900/1800/1900
International bands:
HSPA/WCDMA:
Europe/Asia: 850/900/1900//2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
ATT lite band is 700/AWS. That will not work in England or Germany if you have stated the bands correctly. Both versions will work on 3G & 2G in either market.

Band compatibility is set in hardware, and cannot be changed by flashing a new radio, if that is what you are suggesting. So if you need a particular LTE band, the phone you buy needs to be compatible with that band when you buy it.

Thanks for quick responses, everyone.
If I buy the AT&T one but I'm on T-Mobile's (bulls*** fake 4G) HSPA+ which runs on AWS 1700/2100, I imagine that would work still? Or when it mentions 1700/2100 that is segregated for downlink and uplink? If that is so, then dammit, I will have to re-evalute my life!

I see. I brought up the question about radios because, as you probably already know - since it was on XDA headlines and that, TMo's SGS2 and ATT's Skyrocket + Galaxy Note were able to switch radios. Specifically, the Skyrocket was able to flash SGS2 HSPA+ radio and fully utilise its speeds.

The comparison of the Intl XL and X AT&T is making me assume that HSPA+ will work on T-Mo at least, since it supports both AWS 1700 and 1200. I guess the Intl XL only supports 2100, which continues to leave me a little confused (when comparing it to Skyrocket + TMo's HSPA+).

Safe!

You can probably flash XL and X ATT radios, but they will operate on the same bands as always.
I have a very strong feeling that the X ATT radios will be better if you are on AT&T though.

Its impossible to be 100% positive on the compatibility, since the phone is not even released yet.
But yes, the band T-Mobile uses (1700/2100) one is used for upload, and the other for download, also known as Band IV.
The 2100 band normally included on AT&T phones (for 3G international use) is Band I. So the One XL will probably not work on T-Mobs 3G network.
They have no reason to include T-Mobs band on an AT&T phone. But they do have motivation for including Band I for its international traveling customers, since this band is widely used in Europe, Asia, and other places.

Since there is no release yet, we're all speculating - which is okay.
I've been researching mobile frequencies and bands, and it seems that since there is WCDMA support listed on the specifications for frequencies: 850 / 1700 / 1900 / 2100, they fall into bands:
1 (2.1 @ DL 2110-2170, UL 1920-1980)
2 (PCS 1900 @ DL 1930-1990, UL 1850-1910)
4 (AWS @ DL 2110-2155, UL 1710-1755) could be band 10 (Extended AWS)
5 (850 MHz @ DL 869-894, UL 824-849)
The sole LTE band is:
17 (LTE700 @ DL 734-746, UL 704-716)
whilst 1700 and 2100 are also used for LTE.
DL = downlink range
UL = uplink range

The only thing that could prevent cross-compatibility (which, as mentioned, would favour AT&T) is having the LTE chipset separate from the HSDPA chipset. Though the case may not at all be for HTC, Samsung's Skyrocket (MSM8260) and Galaxy Note (MSM8660) have a single chipset that hosts LTE and HSDPA bands - thus their radios are interchangeable.
Do any of you know the specific radio chipset that is used in the One X for AT&T?
I'm assuming it's the radio on the listed SoC Qualcomm MSM8960 - which is also on the international One XL that is specified to simply host the 1800 / 2600 bands.

As I said, as this is all speculation, a development hack on the modem or straight compatibility, or non-compatibility, could be the case. I'm just going to keep my fingers crossed!
Thanks so far for all of your replies!

To contradict my previous post, HTC's website doesn't even list support for 1700 MHz for the AT&T version of the One XL.

I don't think it's possible. The chipsets between the XL and X are VASTLY different Qualcomm Snapdragon S4 vs. Nvidia Tegra 3.
The Skyrocket, AT&T LTE Note and T-Mo SGSII on the other hand all use the same Snapdragon S3 Qualcomm chipset.

Simply in pertinence to my usage of "X" has always been about the AT&T derivative of the original One XL. Sorry for the wording, I'm at my uni's library - scholar mode on!

They may not be interchangeable between one x and one xl but you might be able to do that between one x and one s

@ senkulpa
Lets hope for them to compatible. Are you contemplating switching to AT&T if they are not?

I'm stuck on contract until November with Terrible-Mobile.

I kind of have the inverse problem to this...
I'm in the UK currently, and hoping that EE's 1800MHz LTE network is given the green light for Q3/Q4 - I want a One X, but it won't be future-proof (i.e. LTE compatible), so a One XL would be great! Also I might be in the states quite a lot over the next couple of years, so it would be nice to have an AT&T LTE-ready phone.
Considering importing the One XL and using it over here - also have the benfit of S4 vs. Tegra 3...
Cheers,
Su

Wouldn't be surprised to see a carrier out their own One XL variant.
I have a feeling that the One XL is international, but will require region/carrier specific versions based upon radio bands. While you can roam on HSPA+, you're going to probably be tied down to specific carriers/countries for LTE service.
Of course, development-wise this only matters for radio firmware and RILs, so development efforts won't be carrier-specific if we get S-OFF.

They're the same radio and software, but physical antennas cannot be changed. Either it has it, or it doesn't.
