It works on TMO, AT&T doesn't have WCDMA 1700, TMO version doesn't have LTE 850.
Im actually using it vice versa, AT&T on TMO G2.

If it's missing 1700 will I be missing anything running it on tmobile? Is that a frequency tmobile uses?
Edit:
Never mind, I realized tmobile uses that band for wide band audio calls so you lose hd voice.

I put my ATT D800 on a T-Mobile prepaid Sim a couple days ago. I get better speeds on TMO's LTE than I do on ATT's, in my home. Other location vary. Given i get more than enough speed, I am not concerning myself with 1700

Using unlocked Tmobile phone in Canada?

Does any one know if I can use the tmobile G2 with a canadian wireless plan if its unlocked. I have read about all that tri band stuff but its a little above my head.
Thanks!
T-mobile does not have the same 3G/4G bands as Canadian carriers (Bell, Rogers, etc)
You will only get EDGE. If you want 3G/4G go with an unlocked AT&T phone.
and if ive read correctly, you need to go to a carrier that uses gsm (because tmobile phones use gsm)
Umm, not sure what only getting edge means. Does that just mean no data, just voice and texts?

As of 2011 there are three levels of data speed that are used and the order goes like this:
4G
3G
EDGE
The speed decreases as you go from 4G to 3G, and EDGE being the slowest.
You will receive data, just not at blazing fast speeds.
From what I understand, T-Mobile uses AWS, of which three carriers here provide: Mobilicity, Wind Mobile, and Videotron.
It's not worth trying to get what EDGE you can from Rogers/Telus/Bell.
* Ontario biased *
I would recommend to get an unlocked ATT phone
So after some research, the G2 is a quad band gsm phone, which means it should work on any GSM based carrier. From what I've seen that would be mainly rogers and fido correct? Or are there cheaper alternatives?
Also I looked into the AWS but I'm not sure if my g2 is compatible with AWS. It seems as if tmobile uses both. Does that mean my phone is compatible with GSM and AWS? I'm wondering if you could confirm this Ariel?
Also I will be in the montreal area.
Yes. It will work but the G2 doesn't have the same 3G bands as Rogers. That means you'll only get EDGE which, by personal experience, sucks. I'm not sure about Fido, though.
k, what about an aws service like videotron? That should work as well correct?

[Q] Using LG G2 on StraightTalk T-mobile sim

I am currently on StraightTalk service using a t-mobile sim. I am interested in purchasing the LG G2 with my current sim. Before doing so, I wanted to see if anyone has any feedback with using the 4G LTE services with their T-mobile sim on Straighttalk?
Do you have any suggestions on where I can purchase a T-mobile compatible LG G2? I did find one on negri electronics but it did not mention that it was T-mobile compatible (The T-mobile site doesn't have an option to purchase the LG G2 unlocked currently).
I would appreciate any pointers in purchasing this phone unlocked, looks like an awesome phone!!

IIRC the tmobile, att, and international editions are the same hardware wise. I'd double check, but buying the ATT version unlocked is the cheapest way to do it.

I bought mine retail at the AT&T store and they gave me an unlock code over the phone the same day. I then tried my T-mobile SIM card in it and it worked fine (and I got LTE). But I don't know if the AT&T version has the 1700mhz band for T-mobile's non-LTE 4G. I am assuming it does not.
I just got an email notification today that the T-mobile version is available for purchase. You might look into just buying it form T-mobile. I assume they will have it in their store very shortly and that will surely have the 1700mhz band for if you do not live in a refarmed 1900mhz area.
Cheers,

Straight Talk has AT&T LTE now. That's what I am doing when my contract expires in a few months.
Did some more googling
"LTE 700 / 850 / 1700 / 1900
WCDMA 850 / 1700 / 1900 / 2100
GSM 850 / 900 / 1800 / 1900
AT&T version (D800) does not support WCDMA 1700 / T-Mobile version (D801) does not support LTE 850"
May or may not be a firmware thing.
Not much mention of the tmobile variant anywhere, everyone has the att version to test. However the tmobile press release did say 1700/2100

I wonder if the D801 has band 17 for AT&T LTE. That's 700mhz right?

The Snapdraon 800 chipset has built in LTE, and Qualcomm made a big fuss about it being "world LTE". On top of that the chipset is supposed to have a configurable radio, so my guess would be each version of the phone should support everything and it would be the firmware that enables or disables different frequencies.
the Snapdragon 800 includes “True 4G LTE World Mode” with LTE FDD, LTE TDD, WCDMA, CDMA1x, EV-DO, TD-SCDMA, and GSM 4G LTE with Carrier Aggregation.

Although I am no dev and I dont recommend just trying this, it would be interesting if a real developer could look to see if firmware could be cross flashed to enable a different radio band on this phone since it is all the same hardware and the chipset its self supports all of it.

Good information and a good idea. It's good to know that the hardware is there, so maybe if the need arose then a dev would look into this.

[Q] Unlocked G2 on T-mobile

Hi,
I am looking to buy a factory unlocked G2 and flashing custom rom on it like CM10.2, and use it on T-mobile. Just want to make sure I could get LTE speed, correct?
Currently on Nexus 4 on T-mobile monthly 4g, enjoying LTE 4G speed, so, just want to be sure...
I would suggest you still buy the T-Mobile version, depending on what's important to you. As far as I know, the AT&T version doesn't have 1700mhz AWS band for HSPA+ to fall back onto if you don't have LTE. The two devices (D800 and D801) both have the same LTE bands.
Which version are you considering? I don't know if any of the other versions work on T-Mobile's Band 4 LTE, but when I checked a few weeks back, they didn't. You may be stuck with a T-Mobile version.

Factory unlocked, e.g. : http://www.amazon.com/LG-G2-32GB-Un...qid=1382743380&sr=8-3&keywords=unlocked+lg+g2
The specs listed on that page for LTE are:
4G Network LTE 850 / 1800
Neither of those are T-Mobile bands in the US. Are you planning to use it in the US, or T-Mobile in another country like the UK? I think the UK uses 1800mhz, but I'm just speculating at this point. Sorry I can't be more help!

AT&T LG G2 unlocked to Tmobile. Can I get HSPA+?

I just bought an AT&T LG G2 plan on unlocking it for Tmobile/metropcs (they merged in my area) Will I be able to get full connections to everything once I unlock the phone for Tmobile network? I'd hate to realize I wont get any data or get very slow data after spending so much money.
Since MetroPCS uses Tmobiles system in my area but also still use their systems can I choose if I want to use a metropcs or a tmobile sim card? Or are they both on GSM towers and so there would be no difference? 4G for MetroPCS is available in my area but so is Tmobile HSPA+ which is better?
Not if you don't have the 1700 AWS band...

not sure what you're saying. 4G is 2100. but other than that if i leave 4G area i wont have any reception at all?
4G uses different bandwidths. Not all carries use the same... Still the same old "GSM/CDMA" scenario, just a bit more relaxed.

AT&T LG G2on Tmobile...no signal! HELP!

Just bought an AT&T Lg G2 and unlocked it for Tmobile/Metropcs use and after setting APN settings I still have no connection at all. Im unable to send a single text, get online or anything. Im sure im doing something simple wrong. Tmobile has 4G in my area so i should get great speeds. Anyone got any ideas?
I've entered APN for both 4G and non 4G
Did you reboot? Probably did but it already, right?
yup I've rebooted multiple times. Went into Networks searched networks it found AT&T Tmobile and MetroPCS and a few others. i've tried AT&T tmobile and Tmobile LTE and Metro PCs...all with no luck

I'm afraid that the AT&T D800 does not support AWS/UMTS Bands, which are T-Mobile's main frequencies. I've just pulled this list from Wikipedia:
AT&T - D800
GSM 850/900/1800/1900
UMTS 850/1900/2100
LTE 1900(2)/1700(4)/850(5)/700(17)
T-Mobile - D801
GSM 850/900/1800/1900
UMTS 850/1700/1900/2100
LTE 1900(2)/1700(4)/700(17)
Namely, you are missing UMTS band 1700 which manages about 50% of T-Mobile customers' HSPA+ connection. That being said, the fact that you cannot connect to T-Mobile's LTE band 1700 is weird. Also, UMTS band 1900 should also work.
Perhaps you're in an area with ONLY UMTS 1700 which would not work with the AT&T LG G2. Do you know if there's LTE coverage in your area?

Yes I am in DFW area which is one of the largest LTE areas Tmobile has. I'm unable to get a connection at all. It says phone is for "emergencies only" I cant make calls, text, or use web.
Sounds like the phone is not SIM unlocked. Need to verify it is SIM unlocked. Also where did you buy it. If the phone was bought from a person it could have been reported stolen or lost and blocked from T-Mobile.

I bought it off Swappa. Ill try the unlock code again but it said it was unlocked. it doesnt come up with any error when i put the new sim card in anymore.
You're likely in an area that does not have HSPA 1900 coverage; and since you're AT&T variant doesn't support the band, is showing no service. Locking onto LTE wouldn't help as HSPA is required for voice access.
I created a thread in the Q&A asking for ways to enable the missing AWS band on our AT&T / Canadian variant handsets. It was doable on Samsung and am hoping it can be done on our handsets.
turns out MetroPCS had to activate it. you cant just stick a sim into a new phone. they have to activate it on your account. $15 later (yeah i know...its BS) but the Lg G2 is up and running and getting 4G speeds
