4g service question

Hey guys,
I am a little lost on this. I was looking on the Infuse and thought about getting it and unlocking it to use with tmobile and was wondering if i would get 4g speeds on it. Here is the bands i pulled off on AT&T's website for the phone:
GSM/EDGE:GSM/EDGE 850/900/1800/1900 3G - UMTS/HSDPAHSPA 850/1900/2100 4G*HSPA+ with enhanced backhaul
According to this, it should work. Am i mistaken?
Thanks

Um, why would you think it would work? Do you see UMTS1700 in there? I don't.

I thought it used 2100? I don't know much about the bands. Just started reading on who supported what.

tmobile uses mainly the 1700 band for 3g/4g. they also own the 700 band but i dont believe they use it. att is mostly on the 850 and 1900 bands. european and asian bands are typically 900 and 2100 so they dont really use those bands to keep unlocked phones off the network. the infuse does not work for 3g and 4g on tmobiles network, sorry.

ahh ok. that makes sense now. I've mainly stuck with tmobile phones, except tried an iphone a couple of times. but att has some cooler phones that i thougth i might want to try, but guess that won't happen now . I use the net on my phone alot, so it would be an issue.

Actually AT&T's weird bands have nothing to do with keeping unlocked phones off their network, just the fact that 2100 MHz wasn't available in the US for any carrier.
UMTS2100 is for international roaming, as it's the standard UMTS band in almost every other country.

T-Mobile uses 1700 and 2100, and you NEED both for 3G/4G to work.

i though the att bands were the same as rogers, bell, and telus use in canada? and the same as used in some other countries in the americas and in places like new zealand. i wouldnt exactly say att has the weird bands in this case.
maybe in a year or two att will merge networks with t-mo and you will have a huge selection of compatable phones.

its the same as rogers in canada, and telstra in australia. i belive bell and telus are cdma.

the bell vibrant is an i9000 and the telus fascinate is a t-mo vibrant, the modems all work on the captivate. trust me they are all gsm networks and fully compatable with att phones.

[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.

SGS2 & GNote: http://www.gsmarena.com/compare.php3?idPhone1=4129&idPhone2=4374
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.

Snapdragon S4 product brief
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.
http://www.htc.com/www/smartphones/htc-one-xl/#specs

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

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.

[Q] Unlocked For T-Mobile

Has anyone unlocked and used the HTC One X on T-Mobile? Does the 3G/4G work?

Are you talking about AWS band support on the One X, or the deployment of T-Mobile's 3G/4G network on the 1900 MHz band?
The AT&T version of the One X does not support the AWS band used by T-Mobile for HSPA+ (3G/4G) data. Some have theorized that the One X has AWS support in hardware, but its just not supported in software. As was the case for some other AT&T phones like the Note and a couple others (flashing a different radio enable AWS support). But nobody has gotten this working on the One X. Some folks have speculated that it might be possible if/when we get S-Off.
But also, T-Mobile has started deploying 3G/4G on the 1900 MHz band in some markets: http://androidandme.com/2012/09/carriers/t-mobile-one-city-closer-to-nationwide-4g-hspa-for-unlocked-and-att-phones/
If you are in one of those markets, you may get 3G/4G data speeds on the AT&T One X.

who's in Vegas with the international phone?

From what I hear the 1900mhz band for T-Mobile in Vegas gets 4g speeds. Wondering if anyone out there has an international phone model and can tell us about the speeds. I made the mistake about buying the International model, because it's black. I love this phone even though I lack 4g speeds currently, but I'm curious at what's coming.
Thank You

The international version and the T-Mo branded device have the same radios. They read the same frequencies. There would be NO difference in performance. What you can do it change your build.prop for T-Mo specifics or install a T-Mo based ROM. Either way, there should be no differences with 4G.

No they don't. Currently only the T-Mobile one S supports 4g speeds.

I've run us radios and eu radios... It's the same firmware for the same hardware. Any difference in performance is ROM based

Here's the deal:
Before refarm:
2G Network GSM 850 / 900 / 1800 / 1900
3G+/4G Network HSDPA 850 / 900 / 2100
After refarm:
2G Network GSM 850 / 900 / 1800
3G+/4G Network HSDPA 850 / 900 / 1900 / 2100
All depends on where you are (location/tower)

Btw the refarm in Las Vegas is done, so if you are in Vegas (as i am) and are not seeing "4g" speeds yet, you likely never will. I now get hspa+ speeds in some areas where i used to get edge speeds.

Does this unlocked LG G2 from Expansys work with AT&T LTE?

Please help me check out this http://www.expansys-usa.com/lg-g2-smartphone-32gb-black-unlocked-255286/? I'm looking to get it to use with AT&T. The specs doesn't talk about AT&T nor LTE. $499.99 is a great price if it can work with AT&T LTE. Thanks

It says D802 right on the page, so use that to see how it'll work on ATT.

Don't think D802 will work well on AT&T.. Doesn't have the 700MHz frequency which is the main LTE one on AT&T.. Should have no issues at all on T Mobile LTE..

If you aren't hung up on new, check out your local craigslist for a Verizon branded G2. They are usually listed pretty cheap where I am at (in the $225-325 range on average in excellent condition). They are unlocked, you can flash AT&T firmware on it, LTE works and best of all it has wireless charging built in as a bonus. I have been very happy with mine.

It says under Technical Details:
Network: 4G: 800/900/1800/2100/2600 MHz / 3G: 850/900/1900/2100 MHz / GSM: 850/900/1800/1900 MHz
So on AT&T you'll get 3G only. It's missing the 700 (primarily) and 1700 MHz (a few markets) bands for 4G.
On T-Mobile you'd get 2G and 3G only where T-Mobile has refarmed the 1700 MHz spectrum for LTE and moved the 3G to 1900 MHz.

I have a Net10 sim which runs on the AT&T network and I have HSPA+ only, no LTE, which is good enough for me

Of course I know what the thread is, but perhaps mentioning you were using the same phone would have been good. Just mentioning using a different MNVO made it sound like you were just using Net10, not necessarily the same phone.
