I'm actually a little embarrassed to even have to ask this question, I'm also pretty sure I know the answer but better safe than sorry. Can anyone confirm that the Tmobile version of the TP2 is able to access the ATT 3G network? I'm 99% sure it will but that weird Tmob band makes me nervous, any input would be appreciated.
No, it will not. However the ATT version shouldn't be too far behind the Tmo launch so don't worry too much
no offense but what is the basis for your statement, the Tmob version will have
850/900/1700/1800/1900/2100 bands which are basically the ATT bands plus 1700, why would the Wing II not work on the ATT network?

Please show me where you found this data? Tmobile USA 3g network doesn't use the 1900 band for 3g; they use the 1700 band which is why Tmobile has to have devices specifically made for their network and why the Tmobile USA version won't work on ATT USA.
Again to clarify:
Tmobile USA = 1700/2100 for upload/download for its 3G
ATT = 850/1900 for upload/download for its 3G
Now Tmobile USA does use the 1900mhz frequency but that its GSM frequency it is not related to the 3g frequency. Confusing i know, but you asked.
One of the images advertising it does state all those bands, but does not differentiate which are for gsm and which for 3G (which can be misleading and confusing, ergo the clarification by jim_0068 ^). Though if they share the 2100 I have no idea whether you can get limited functionality or if you HAVE to have both of them. *shrugs*

actually this is not entirely true either,
AT&T is using 850 and 1900 Mhz for their 3G network,
it was revealed recently that they are pushing the 3G network to the higher frequency (850) and plan to have the 3G completely on 850 by 2010.
if AT&T is using 2100, we would've been able to use the european HTC devices which has the 2100 band.

As far as I'm aware:
GSM: 850/900/1800/1900
UMTS:1700/2100
And therein lies the problem... While it supports all the bands that would be required, only a small subset actually apply to a 3G connection/signal...
Minimally, that would be the specs for it to work on T-Mobile, and quad-band GSM is just standard on 99% of phones these days...

You're correct and i edited my post it is 850/1900 for ATT US 3G
I gaurantee you that the T-Mobile Touch Pro2 will not work on ATT's 3G Network At All... the frequencies for ATT will only support the 2G Network and therefore only phone calls and text messaging will work.
let's not go that far, let's not forget gprs (same speed as dial-up) and more importantly EDGE (for some that's more than enough).
when I go into the phone settings -- band I have these options on the Tmobile TP2:
GSM (900+1800)+UMTS(900+2100)
GSM (1900+850)+UMTS(1900+850)
UMTS(2100+800)

hmm, now I think the T-Mobile Touch Pro2 works on ATT's 3G Network.
It should also work worldwide too.
oooh, European bands, "standard" North American bands (they're not really standardized, neither in the US nor Canada and Mexico is barely getting 3G into place), and no idea what the last one is for, sounds like cdma...

I think those numbers are for software only, in fact you probably don't have the hardware to support the frequencies of the wrong carrier.
seems that 800mhz is for Japan
and it doesn't allow for all of the North American bands (it's missing the 1700 one).
Could be just a software thing without hardware support, though that might be a tad odd, any way to check if it is?

My Xperia X1a shows UMTS (900) even when I check the settings... IN FACT only the X1i supports
It's very likely that the numbers you are seeing are actually all of the frequencies that are "summed up" and therefore the TP2 for T-mobile does not have the actual hardware.

Those options have been around with the custom ROMs, I have that too on my Fuze, if your hardware doesn't support it then it'll just be an eye candy.
Bottom line is this, if you want to utilize AT&T's 3G, then you'll need to wait for AT&T's Fortress because you need the 850 and 1900 band (UMTS band II). If you want to use T-mobile's 3G you still need a TP2 that has the 1700 and 2100 band (UMTS band IV), and no you cannot use european TP2 to access US T-mobile's 3G band because european's (and asia's) 3G utilizes UMTS band I, they are on a slightly different frequencies even though they are categorized both on 2100Mhz.

I'm new here and I enjoyed this site very much. I have one problem with my TP2. Somehow, 3G network is not working after I installed Hard-SPL and unlocked T-Mobile TP2 switch to AT&T sim card. Everything is working fine with AT&T's sim card I was able to made phone calls, received, SMS, and web browsing. ATT 's 3G network is available around my home, but I can not get 3G on TP2 instead a EDGE network. Can unlocked TP2 handle AT&T's 3G network? or a .cab file I can download to fix this?
idk for sure but i think t mobile uses a different frequency for 3g from at&t so if they are you are stuck with edge speeds on at&t man sorry
I have the tmobile TP2 and i can confirm from talking with ATT that the phone does support ATT BUT i was unable to use the phone on 3g. The phone DOES support the signals for 3g but am still unable to access the towers in my area. I think the phone may be hard set to look at tmobile towers, is there any way i could reset the device to open up its tower usage? Hopefully i can get an answer but no tmobile TP2 users arent screwed in the US we just need to find a fix
It was my understanding that the tmobile tp2 does NOT have 850/1900mhz 3g on it. It does have aws 1700 for sure. Not sure about 2100mhz though for overseas.
This issue has been covered many times in the numerous AT&T threads on this board.
I'm sorry to tell you that the T-Mobile TP2 hardware radio was limited to using 3G over the 1700/900Hz frequencies, while AT&T currently uses 1900/850Hz only. It's unlikely that any change can be made to the radio software wise to fix this issue.
Just to make things clear the issue has nothing to do with Hard SPL or custom roms.
T-Mobile UMTS 1700/2100 Mhz
T-Mobile 3G runs on UMTS 1700 up and 2100 down. Unless you have a device that runs on those specific frequencies, EDGE is the best you can do with T-Mobile if you opt to run on their service.
ATT offers UMTS or 3G using 850mhz(the old TDMA band) and 1900mhz. While T-mobile offers HSDPA (technically 3.5g part of the UMTS specification) using 1700MHz for uplink and 2100MHz downlink.
Because HSDPA is part of the UMTS spec, it’s backward compatable. However, you have the limiting factor beging that the frequencies the individual carriers use to transmit the data.
Europe and Asia’s 3G runs on 1900/2100mhz. North and south America is supposed to use the (AWS) 3G spec using 1700/2100mhz
ATT didn’t want to wait, like T-mobile is doing, for homeland security to vacate those frequencies and launched on 850/1900mhz instead

I heard that t-mobile did not have enough spectrum in many areas to launch 3g in its existing 1900mhz. At&t doesn't have that issue, or as bad.
Im gonna make this real easy for u. The tmobile tp2 will not work on at&t 3g. The 3g bands are different
Right now "officially" there are only the HTC HD7 and Dell Venue Pro available on TMobile USA.
Does anyone know which other phones would work (after unlocking) with 3G on TMO US?
er...none?
I think so far only these two WP7 devices supports AWS bands.
On other platforms is different, as in the case of latest High-End Nokia devices (but Symbian OS):

However it is a fact that the multi-band support, increases the cost. Is better to invest in features that do will be use
Best regards
Many WCDMA devices support the 1900 band, if you don't care the 1700 band.
but he asked about 3g...the phones don't offer 3g. Sure 2g works
3g nope
And consider 1700 AWS band with no longer be T-mo 3G after merger (AT&T needs the AWS band for LTE), you will be insane to spend $$$ on your own handset.
Even on AT&T side, there have been a lot of markets switched over to 850 band for 3G. So, even with a phone that support 1900 band 3G is no longer safe even on AT&T.

Depends where you live. I have Omnia 7 on AT&T so it only has 1900 band, and I don't even notice a difference in 3G from my last phone. I'm sure it's probably worse, but I get 3G almost everywhere.

In my area, all 3G towers were 1900. Then AT&T switched all of them to 850 last year. This year, they switched back to 1900 again. AT&T has indicated in the past that it intends to deploy more 850 band 3G to improve coverage.
I thought the 1900 towers would stay 1900, and new ones would be 850
Virtually all 3G-850 american handsets, also have 3G-1900 band. In other hand, the carriers such as Telstra (Australia) and Telcom New Zealand have also 3G-850, with 3G-2100 band (not 1900); but these last are a minority.
The AWS bands with WCDMA technology (3G), are only used by TMoUS (as we all know); and fatally these bands will be used by "new" Latin American carriers like Nextel Mexico and others like VTR and Nextel Chile.
No larger carrier exists than TMoUS, that use AWS bands, so that all developments in AWS bands, should be first implemented in TMoUS ...until now

That's true but most ppl who buy unlocked/unbranded handsets buy the European models which typically only come with 1900Mhz band 3G for NA. Those handsets rarely ever supports 850Mhz.
If I use unbranded ROMs on TMO I have gotten 4G on both my HD2 and 7.

On both my HD2 and HD7 I will get an "H" signal. I was talking to T-Mobile support and they told me that was 4G and I was getting it because of the ROM. I asked why they would restrict the 4G if the hardware would do it and they said it was to control the number of devices on each network. I can only get it with an unbranded ROM. I'm not arguing, just telling you what they said. HD7 according to T-Mobile is NOT a 4G capable phone but mine gets an "H" signal all the time.

HSPA --> 'H' indicator on your handset (with custom ROM)
HSPA+ --> what T-Mobile advertises as "4G"
The H does not mean 4G. It means you have HSPA. In the carrier-specific ROMs they overwrite the H bitmap with one that shows 3G instead, to "help" their customers and avoid confusing them.

[Q] Using T-Mobile Galaxy Note 2 on AT&T's LTE (Will It Work if I do the Following?)
Can't you flash an AT&T firmware on a T-Mobile Samsung Galaxy Note 2 handset to get the necessary AT&T LTE Frequencies since the LTE radios on both AT&T's and T-Mobile's Note 2's are the exact same? Or is unlocking the Note 2 via T-Mobile more than enough to take advantage of AT&T's LTE Network?
Tread carefully, I'm currently trying to get my phone out of a rather nasty bootloop/corrupt IMEI situation after trying just that earlier today.
But I did get it to work, even pulled 35 Mbps on a speedtest.
Things went to hell after trying to revert back to the T889V modem. (In case I needed the AWS HSPA, for proof of concept and also warranty purposes).
so our phone's LTE modem is compatible with AT&T LTE bands? sweet.
^^^ Did an LTE status show up when you ran the Speedtest; this was with an AT&T Sim, right? ?

Virgin Mobile Canada LTE SIM (previously confirmed working in an Galaxy S III), and yes the LTE icon showed up immediately, Speedtest says LTE too, and the speeds are way beyond what I had with HSPA in the same location.
Doesn't AT&T's LTE run on different frequencies; so will T-Mobile's Note 2 match with AT&T LTE Frequencies after flashing to AT&T's Firmware?

Tmobile's T889 supports LTE on AWS and 700 (band 17).
AT&T's i317 supports LTE on AWS, 700 (band 17) and also on 850 and 1900 (band 2).
So yes, our phone has the ability to work on SOME of AT&T's LTE network, but not all of it; it will just depend on which frequencies they're using in your area. I believe AWS and 700 are new for AT&T, so they're probably fewer and more between at the moment, whereas their current network is mostly 1900 and 850. Not sure what kind of upgrade they have to do to switch their old HSPA 1900 towers to LTE support.
Silly question, so is a tmobile note 2 capable of handling AT&T's LTE network on the 850 and 1900 bands; is this something controlled by software, or a hardware limitation, I thought the Qualcomm radios on the AT&T variant and tmobile variant were the same.

I live in America and was thinking about ordering the S4 GT-i9500 for Wolfson Audio chip reason. I wanted to use Tmobile because they have the best prices. I saw that the i9500 network is:
Network: 2.5G (GSM/ GPRS/ EDGE): 850 / 900 / 1800 / 1900 MHz; 3G (HSPA+ 42Mbps): 850 / 900 / 1900 / 2100 MHz
And from https://en.wikipedia.org/wiki/T-Mobile_US#HSPA.2FHSPA.2B_.224G.22_upgrade, I see that HSPA+ uses 1700/2100 Mhz. It also saids:
Band IV AWS consists of the 1700 / 2100 MHz band pair. Data is transmitted upstream on 1700 MHz and downstream on 2100 MHz. A device must support both frequencies to access T-Mobile's AWS data services.
I don't understand, but sellers on ebay are claiming i9500 will work with Tmobile's 4G in America. How would the i9500 work on the American Tmobile network if it doesn't use the 1700 frequency? What would be the draw back?
Tmobile is refarming its 1900Mhz band for hspa+. If you're in an area that has it you could get 4G with that and pretty good speeds. You won't get LTE and if you're in an area without the 1900 you'll get 2g speeds.
Here's a more technical explanation.
T-Mobile used to exclusively use the AWS (1700/2100) spectrum for DC-HSPA+42mbps. They are currently refarming this for LTE use.
HSPA+21mbps is being moved to the 1900mhz spectrum. So, in areas that have been refarmed, you will have HSPA+ access (NOTE, no 42mbps). In areas that are not refarmed, you'll be limited to EDGE service.
I have a Galaxy S2 GT-i9100, so I have the same limitation. I signed up with T-Mobile about 2 months ago and on a weekly basis, I'm seeing towers refarmed. They intend to have it nearly completed by end of 2013, thus limiting the areas you'll be on Edge only. Eventually, their entire 1900mhz network will be HSPA+ 21, with their AWS network being LTE.

Their HSPA+ network on 1900mhz is limited to 21mbps.
Basically, their network prior to refarming was:
1900mhz (PCS) - EDGE
1700/2100mhz (AWS) - DC-HSPA+ 42mbps
They have since acquired a TON of PCS and AWS spectrum from; failed AT&T merger, Verizon spectrum swap, and MetroPCS merger.
This will allow them to expand to new markets currently not served, as well as expand bandwidth in existing markets. So, their current plans are to refarm the network to;
1900mhz (PCS) - HSPA+ 21mbps
1700/2100mhz (AWS) - LTE
There will be some limited spectrum for the old EDGE (PCS) and DC-HSPA+ 42 (AWS) available for legacy devices, but that will eventually (at least 2020, most likely) go away. The goal is to have LTE over their core network by mid-2014, and HSPA+ 21mbps being the expanded fallback network. T-Mobile will also be taking part in the 600mhz auction in mid-2014. Their network plans will be made more clear (VoLTE, LTE-A) after that auction. Lower frequencies allow for better building penetration. T-Mobile is currently silently lobbying the FCC (through other groups) to remove Verizon and AT&T from that spectrum auction for the sake of competition.

so eventually you'll be able to access the 21mb range? Thus, if in a refarmed area, you could get 21mb with a i9500?
For explanatory purposes: Ever noticed how, if connected to a 100mbps LAN, you don't ever see 100mbps? That's link speed, not real world.
Applied here, HSPA+ has a top link speed of 21mbps (assuming both ends are compatible). DC-HSDPA has a top link speed of 42mbps. Real world performance will be 3-8mbps on the former, and 5-15mbps on the latter. I've seen spikes up around 12mbps and 25mbps, but those are incredibly rare. Bottom line is, do not expect LTE speeds. I currently have a phone that has 21mbps HSPA support on PCS (1900mhz), and on T-Mobile, I get 6-7mbps in most HSPA areas.
I hope that helps.

Wow, kind of considering the I9500 again. I live in Austin, Texas. How will I know if Tmobile converted here and if I can get the 6-7mpbs in HSPA where ever I am here? Also, right now I have a Nexus S with 3G. I have to admit that I only am able to get 3G(Tmobile) about 50% of the time and the rest is edge speed. Would HSPA consistency be this bad?

Also, right now I have a Nexus S with 3G. I have to admit that I only am able to get 3G(Tmobile) about 50% of the time and the rest is edge speed. Would HSPA consistency be this bad?

If you got the Nexus S model sold for T-Mobile, that has AWS support. That means that switching to a PCS 3G phone like the i9500 means that AT BEST you will have the same Edge/3G coverage ratio you have now, and at worse you'll have mostly Edge coverage. Your 3G data speeds will be faster in the areas you get it though. It will be a tradeoff.
EDIT: Here's a user-generated map of areas that have had 3G and HSPA+ refarmed to PCS. Looks like a few rowers directly in Austin have been refarmed. This is a massive project by T-Mobile and is nowhere near being complete. However, an areas HAS to be refarmed in order for them to launch LTE, so refarmed markets (that already offered 3G/4G AWS service) are the ones that are getting LTE eventually.
