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...

hmmm why is there 800 MHz?
Obviously this is some bull**** because it supports all of the 3G frequencies of worldwide carriers and american carriers.
I wouldn't trust this guy, he has 4 posts and he's obviously posting rumors.

Sorry for the horrible pictures, using a g1 to take them. I love watching people jump to conclusions.

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.

Help Please! Will the galaxy nexus work with Mobilicity?

Hey Everyone,
I recently pre-ordered the Galaxy Nexus from Bell on contract for three years thinking that Wind and Mobilicty are CDMA. (I know, I'm crazy). I have just figured out that they are in fact a GSM network. My question is that if I changed my order from bell from a three year contract to unlocked, will it work on Mobilicity's service? I know there probably won't be 4G speeds but if I can get a plan with unlimited calling and data for $17.50 per month instead of the 500mb and 200 minutes im getting with Bell for $50 a month, I'd rather get it unlocked.
Note: If you say it will work, please provide some evidence of some sort, e.g. some specs that state that the Galaxy Nexus will work with Mobilicity's network
Thanks so much everyone, and if you could reply as fast as possible it would be extremely appreciated as the promotion that they have for $17.50 might be over really soon so I'll buy it right away.
-Mosh

Galaxy Nexus is penta-band 3G phone...so the HSPA version will work on that network.
You're ok with it,enjoy the phone.

Are you sure? I don't mind having slow speeds (HSPA) but my budget is really low and I really want to make sure that the phone will work with Mobilicity out of the box

Yes it will work. Relax

Thanks again all

Even though you would have a hard time finding any GSM/UMTS/HSPA network it doesn't work on you could always check the list on Wikipedia.
http://en.wikipedia.org/wiki/List_of_UMTS_networks#Americas
It says Mobilicity uses the same frequencies as T-Mobile US, a frequency that is both listed in the official specs and is something some people is already using it on without issues.

Compared to HSPA+?
Edit: So the Galaxy Nexus works with 1700 band IV (AWS)? http://imgur.com/NJrCK
Edit2: So, according to http://www.gsmarena.com/samsung_galaxy_nexus-4219.php, the galaxy nexus has the following:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1700 / 1900 / 2100
So Mobilicity definitely supports this?
Edit 3: According to a Wikipedia page on Mobilicity:
"Network
The company also has a cell-site sharing agreement with Bell Mobility to share cell tower space in all Mobilicity zones[12]. The network uses the UMTS IV frequency band, also known as AWS, to provide UMTS (with HSPA) service[13]. Using this band, user equipment transmits at 1710–1755 MHz, and receives at 2110–2155 MHz. AWS is the same frequency as Wind Mobile and Videotron in Canada and T-Mobile USA. Like WIND, Mobilicity does not have a 2G, EDGE, GPRS GSM Network.
Mobilicity's network is compatible with the same handsets and devices as Wind Mobile and Videotron networks, and UMTS handsets and devices offered by T-Mobile USA.

So is the Galaxy Nexus a UMTS handset that works with T-Mobile USA?

I already said so, yes. Should be no problem. My mention of T-Mobile US was only if you wanted to know actual users who are already running it on those frequencies.
Yes, it's a UMTS handset that works with T-Mobile USA. I don't know how I can make it any clearer.
EDIT: Well, to clarify it a bit more I can say that HSPA (HSDPA and HSUPA) HSPA+ are improvements upon UMTS. In other words, every HSPA device is a UMTS device.

Perfect, thanks so much!Also, according to other websites it has UTMS 1700/2100 or HSDPA 850 / 900 / 1700 / 1900 / 2100 or Network (3G) HSDPA 850 / 900 / 1700 / 1900 / 2100 so basically it will work for sure right?
Sorry for repeatedly asking the same thing, I just want to be sure. One more yes, and I'm going to change the order from 3 year term to unlocked

How many different ways do we have to say this? It has quadband GSM and pentaband 3G, if you put in a North American SIM in the phone, it will work.

[Q] will this E975 work in USA (AT&T) ?

Greeting all,
please help me for those who live in USA or anyone know about this LG E975 unlock will work in USA AT&T for calls and data
I know 4g will not work but i'm asking 3g or H will work?
I found one has Operating Freq GSM - 850, 900, 1800, 1900; UMTS - 2100

It will work for calls and data but data will be 2G. AT&T uses 850/1900 frequencies for 3G and 3.5G and the E975 you found only supports 2100. So, to answer your question, 3G will simply not work.

[Q] LG G3 D855 4G LTE issues on T-Mobile USA

Hello everyone,
I just got my LG G3 today and I'm encountering an issue getting 4G LTE on my D855 (international version) on the T-Mobile US network. I looked around and searched the forums to find a solution to this 4G LTE problem specific to this phone. I tried going into the hidden menu (3485#*855#) and changing the bands and such, nothing works. I haven't rooted my phone or flashed anything yet, as I haven't found any tutorial in which doing so would resolve this issue for this specific model.
I do get HSPA on it, which gives me about 7mbps, much slower than I anticipated.
Does it mean that I won't get 4G LTE at all? I will be in Hong Kong for a few months and was wondering if I would get 4G LTE there on T-Mobile using this phone since it's the international version and they do offer 4G LTE over there. Anyone know if it works over there?
If there are no solutions, I might just sell the phone and get a different model that works.
I'm located in Southern California if that helps anyone.

@darkelfx, you need to check which LTE bands that model runs off of, and see if T-Mobile uses those. I work for tmo, and we did a lot of work on our network to make it more compatible with unlocked devices, however, I know that since there is a difference in the bands att uses, their devices do not pick up our LTE 90% of the time. They get HSPA+, just like you do.

These are the bands being used and my version is the international version (not the AT&T version).
2G Network: GSM 850 / 900 / 1800 / 1900
3G Network: HSDPA 850 / 900 / 1900 / 2100
4G Network: LTE 700 / 800 / 900 / 1800 / 2100 / 2300 / 2600
I do not get HSDPA+, I get the slower 3G speed, which is HSDPA.

for 3g you need to have 1700mhz as well
for 4g they use a combo 1700/2100 or AWS is the nickname.
Sorry to say but the D855 is NOT compatible with any U.S. LTE bands.

Yeah, I found this out as well researching the G3 before buying any of the variants for use on Tmo. None of the variants, outside of the 851, will work on Tmo's LTE. You'll get voice and 3G (HSPA), but not LTE connections with TMo.
As for getting LTE in HK, it won't be on Tmo's network, as Tmo does not have any networks in HK. You might get data roaming and all, but I haven't looked too much into that as I don't do much international travel. You would connect under a roaming partner there, if there are any under agreement.
Or you could swap in another SIM for use in HK.

This worked for me.
I had exactly the same problem.
Watch this video on YouTube for the G2, follow the instructions and it will work.

Hi, I use LG G3 D855 and looking for solution to get LTE on T-Mobile USA. After some research inside the forum, I decided to try to use CyanogenMod (CM 12.1) on my system.
It works well and now I can enjoy LTE on T-Mobile network, even though not pretty stable yet, but I am good with that since the OS still ongoing development.
You can try to download the OS on Cyanogen official website, and use the latest update available.
In order to confirm if you get LTE signal, beside check on your LTE sign, you can use LTE Discovery apps whenever you lost LTE connection and try to reconnect on an LTE signal.
Oh, forgot to mention, I am located in College Station, TX.

Using AT&T G3 in South Korea(LTE band & frequency question)

Hello, everyone.
So, I have a AT&T G3 with me and planning to go to South Korea and use Korea cellular carrier while I am staying there. With this, I have a question regarding whether my G3 will have LTE signal in South Korea
*(Information that I am going to write below is from both gsmarena and wikipedia)
For AT&T G3, its LTE band supports LTE 700 / 850 / 1700 / 1800 / 1900 / 2100 / 2600
The cellular company that I am planing to use is SK telecom and they support LTE band 1, 3, 5 and frequency of 850, 1800, 2100
(I will attach the screenshots of those information with this post)
With this information, would I able to use full LTE with my G3 while I am in Korea?
Appreciate your comments.

Its kinda hard to say. I thought there using lte-a
But your maybe lucky and 4g or lower but i wouldnt count on it.
It all depends on the bands. It doesnt mean because you 2100mhz to, that they use the same band to.
Just go over there sell yours if it doesnt work and buy a local g3
