Stupid Question - Tmobile TP2 radio on ATT 3G

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 had the same question but according to what i have found, T-mobile uses 1700/2100Mhz (need both) for their 4g frequencies and the htc one x is only compatible with 1900Mhz, 2100, 1800, and 850. there have supposedly been customer's reporting that have been using a 1900Mhz frequency on T-mobile but i have not been able to confirm that. I have heard that they are planning to use the 1900Mhz frequency to roll out their LTE late this year or next but to answer your question it would only get edge for now, (officially at least).

Yeah man, after bugging T-Mo USA's tech support and stalking confusing threads in T-Mo USA forums, I've grasped the concept... Mostly. You're 100% correct.
Yeah, you're right, we'll only get Edge. Very fast Edge, however, but still Edge. Now, the people in the USA who are getting 4G out of the X are the few people living in areas where T-Mo USA has released the 1900HSPA+. But, the roll out is just starting.
Also talking with Tech support, the guy was hinting that I should wait until summer if I don't see what I like then, wait until Christmas. I think I'll do exactly that.

T-Mobile 1900MHz HSPA+

According to www.airportal.de there is 1900MHz tower right next to me, but my GN does not want to connect to it, even when the overall signal is low. Is there a radio update that will allow me to use 1900MHz band?
I checked what tower my phone is connected to by entering *#*#4636#*#* and CID does not match to the one on the site.
My radio is UGLH1
Thank you.
EDIT: my sim card is one month old.

I was not aware that T-Mobile has different sim cards for iPhines (other than size)
My friend's iPhone 4S on T-Mobile has 7-8 Mbts speed standing right next to me, but I can only get 2-2.5 Mbts.

You don't need a microsim for it to work afaik. It will work on any "AT&T" phone. And it should work on the GN since it is pentaband.

SIM card size does not dictate frequency.

Even if 1900mhz is available, I'm sure that T-Mobile would prefer you stay on the surely more stable 1700/2100mhz combo at this point in time... likely a SIM issue though.

But his old SIM probably doesn't support 1900mhz HSPA. Yes, he doesn't need a Micro SIM just to get the frequency, but he likely does need one of T-Mobile's new SIM cards that's properly provisioned for the 1900mhz connection. I think people are just getting confused over the fact that T-Mobile is pushing the Micro (soon to be Nano also) SIMs w/ 1900mhz for unlocked iPhone customers. It doesn't mean they're only used for iPhones, it just means that it's the primary reason they're switching frequencies and offering these to those customers specifically.

"Better" how? And T-Mobile uses 1700/2100mhz combo, not just 1700mhz.
Most people would prefer 850mhz and 1900mhz because its interoperable with AT&T's frequencies, allowing a wider range of devices to be used on T-Mobile.

Lower the frequency better Penetration right.

But like I said, T-Mobile doesn't use just 1700mhz, it uses the combined 1700/2100mhz AWS frequencies.

To the OP: Do you have a phone without AWS that you can use to test and see if you are actually picking up that tower? Or a non-Nexus Samsung phone that can be restricted using the band select menu.

I don't think a SIM card needs to be re-provisioned just because the carrier has a new frequency. All the folks who started seeing 3G on their unlocked iPhones were using SIMs they'd had for years.

It's not a combo. In Europe they don't refer to the IMT band as 1900/2100 combo, they just call it 2100. And they don't refer to the DCS band as 1700/1800, just as 1800. It's one band, and for the purpose of North America, "1700" as a band unambiguously means AWS. In Japan though there is a different 1700 band.

Like he said, he has a friend with an iPhone right there that gets HSPA service w/ T-Mobile. My assumption would be that he needs a new SIM, but again I'm not sure if that's the case, I'm not intimately knowledgeable of how T-Mobile is doing their provisioning.

Just because its sometimes referred to as 1700 doesn't mean that it doesn't use both 1700 and 2100 as a combination.
"The AWS band uses microwave frequencies in two segments: from 1710 to 1755 MHz for uplink, and from 2110 to 2155 MHz for downlink." (Wikipedia)
This is why it's referred to as "1700/2100mhz", although often just "AWS"

I don't understand why a new sim is required. People using old sims in iPhone's have been reporting 3G being available as T-mobile has turned on new markets with the new band.

The problem is, even mentioning 2100 causes unnecessary confusion because for years before the band entered use, 2100 was already well established as referring to the 1900 up / 2100 down IMT band. It leads people - and you've seen them on the forums - to think that they can buy a device with IMT and use it on an AWS carrier.
So "1700" alone is actually less ambiguous.

Just as ambiguous. Pretty sure calling it "1700/2100mhz AWS" is pretty clear. Not sure how dropping the 2100 part helps the ambiguity problem.
Calling it 1700mhz gives off the wrong impression, implying that it'd be better building-penetration wise, even though half of the traffic goes over 2100mhz which performs worse at penetrating buildings.

Because you want to tell customers, when they are trying to figure out if a phone is compatible, to look for 1700. Not for 2100. If you even mention 2100 they will get led down the wrong path. 2100 already had a meaning in the mobile world way back when IMT was first used for 3G service overseas in the year 2002. And the established meaning of 2100 as a cellular band is something that is not operated anywhere in North America.

Or, you can just tell customers to look for both 1700 and 2100 (AWS), which is both unambiguous, and correct. Whereas calling it simply 1700 is misleading. Customers who are shopping in the US are not likely to have heard of the 2100 band used overseas anyway, so your point is moot.

Can I use unlocked ATT S3 on tmobile $30 monthly 4g?

I am reading it might work on edge only is that true?

Different Bands... no 4g, just E... Maybe someone know more than me but IMO you cant use 4g

You can use the phone but you will be restricted to Edge data speeds. ATT and Tmo use different freq bands for 3G/HSPA.
ATT uses 850/1900
Tmo uses 1700/2100
You may be able to get 3G/HSPA speeds once Tmo refarms its 2G bands as 3G, but who know when that will be.

You will only get EDGE in MOST areas, T-Mobile is "re-farming" the 1900mhz spectrum from 2g to 3g/HSPA. They are doing this in order to be able to use the iPhone on their network, but it would have the same effect for any unlocked phone. They say they'll have their entire network re-farmed by the end of next year. I haven't found an official map, but this has places where it has been sighted: http://www.airportal.de/

I tried this on my att S3 and got the sim card and was on the phone with tmobile tech for hours...it never worked and he was trying to tell me it was my phone....not...my phone works great with straight talk.

It definitely works on the AT&T phones. I unlocked mine and bought a tmobile prepaid sim the other day. Able to get 3g in San Jose but still only Edge where I live. Will be switching and dropping at&T once the refarm hits my area.

[Q] Should I get ATT or TMobile GS3

So I am looking to switch to T-Mobile from sprint and want to get the S3. I understand the T-Mobile GS3 works on HSPA+ and operates on the 1700 Band. I also see that the T-Mobile version does not have LTE. Now the ATT version operates on the 1900 Band and will only work on slower speeds until T-Mobile activates the 1900 Band here. Spoke to several reps and they state sometime this month. Will the ATT GS3 have the LTE that will work on T-Mobile when they activate it? So would it be better for me to get an ATT GS3 so that I have LTE when it becomes available? Thanks in advanced

I have Tmobile and it works ok, It depends on the service coverage cause where I live I don't get 4G on any carrier lol.

That's a tough question to answer. Is it a matter of want or need LTE on your mobile device?
Arguably, at&t has better service than t mobile. But since t mobile is still at the stage of refarming their antennas/towers, Tmo could be just the same as their counterpart after its done. I have t mobile and coverage has been excellent. Data speeds are speedy but not quite as fast as at&t's LTE.
On HSPA+, i get great to decent speeds that can get all of my mobile needs online. It would be a plus to have LTE but i don't need it.
Do you get what i trying to get at?
Sorry i had to write this quickly.

I say go for the Tmobile S3. T-mobile's LTE rollout won't be for a long while, and even when it does become available we don't know if it uses the same LTE band as ATT. My guess is that it won't. Tmobile's HSPA+ is plenty fast where I live for all my needs. You will only get EDGE (2G) speeds with TMobile on the ATT version of the S3 until Tmobile refarms their network. But even if they do refarm where you live by the end of the month, the many other places will still only be covered with the 1700 spectrum.

S3 on Edge is a pointless phone. Even with the 1900 mhz bands rolling out, your data will be spotty at BEST. Even in NYC Manhattan, the 1900 mhz bands are probably 20% complete. Go with the TMO version and you won't regret it.

I get up to 25mbps I average about 7-12 who cares about LTE? Go with T-Mo its cheaper and you will get faster speeds. At my home I get faster data speeds than my baby mama on ATT with her HoX soon to be OG Note
sent from my Samsung Gangster S III on the T-Mobile network

I also have the same dilemma.
If T-Mobile will use LTE on the same frequency as ATT currently does, won't using the ATT SGS3 future proof it for LTE on T-Mobile network?
Am I missing something or do these devices have same specs (except T-Mo having 1700) once 3G moves to 1900 on T-Mo?
OP, I suggest you test T-Mo's network for coverage and speed in your area. I will be doing the same.

Get the T-Mobile version if you value fast data speed.
Don't buy a phone and hoping that it will have the correct technology to work on a network that has not even start to build yet.
