[Q] Unlocked G2 on T-mobile - G2 Q&A, Help & Troubleshooting

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!

Why just not get T-Mobile's version?

Great idea but there are no TMo offers yet. They plan to put it in their stores around 8-15 May. So if there is no chance to unlock ATT one I'll wait for TMo.
I'd wait. With the AT&T version you'll only get 850mhz/1900mhz HSPA, whereas the LTE would work fine. You'd definitely want AWS HSPA+ if your on T-Mobile. Their 1900mhz refarming is very spotty and not matured.

Yes anyway I need HSPA+. I use ATT Note2 that supports it. But it is unknows if ATT GS4 supports it as well.
You should definitely wait. Or if you're buying outright full price, just get the international I9505.
Well thanks i9505 is too expensive
1-2 more weeks not a big deal then
If you live in Queens there are some T-Mobile stores launching the fone on the 1st... Actually only 3 stores in Queens launching on the 1st.
It does not support the AWS 1700 band, so wait for the TMobile version. The hardware is not there.
The ATT S3 and Note 2 did not support AWS HSPA out of the box, but a quick tweak using the Qualcomm software fixed this.
Perhaps the same fix applies to the new chipset in the S4?

On Note 2 AWS HSPA can be enabled through service menu so I've made. Do not know about GS3..
Tmobile or ATT version S4
Will T-mobile S4, which I am sure will come as locked, work on ATT network (3G/4G/LTE) once unlocked? It appears that ATT version lacks Tmobile's 1700 band for 3G/4G. But does Tmobile version S4 comes with 1700/1900/2100 plus LTE band that works at both carriers provided that it is unlocked? If not is there an S4 unlocked version that can be purchased so that it works at both carrier's 3G/4G/LTE?

4g lte shoukd work straight out of the box since tmobile uses the same lte band as at&t. and im pretty positive hspa should work too cause you dont need 3 bands all time. I have tmobile note 2 on att and i have all 2g hspa and lte.

Could you please provide a source for this? I've been looking but can't find any confirmation. I was thinking both phones would have the same hardware (cheaper to manufacture) but the modem firmware would simply disable some bands on the AT&T model.

Turns out the hardware is identical on both the AT&T and the T-Mobile models. More info on this post. Cross-referencing posts to avoid duplicating info, and in case someone is interested.
what about unlocking the phone(t-mobile version)? anything available besides buying the code?

[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.

Note3 AT&T VS T-Mobile

Hi, Does any know if its all vice versa?
NOTE3 AT&T and T-Mobile NOTE3 using it with a T-Mobile SIM, (vice versa) T-mobile & A&T NOTE3 using AT&T SIM?
(Both NOTE3 is unlocked & using in urban BIG city)
Will there be any difference speed LTE and speed 3G & 4G you receive?
Will the LTE signal not be as strong each other?
Will be any problem each other (vice versa)?
Do you think we can enable AWS on NOTE3 AT&T? (same like Note2 and S4 AT&T)
Which hardware Note3 AT&T or T-Mobile is better having multi-LTE or more compability network each other (freq band spectrum)?
I don't really know much about LTE signals between AT&T and T-Mobile, compatibility, etc. So, I was wondering if you can help me to decide which one are those? How long to get unlock code from the 1st day i purchased with full price NOTE3 AT&T and T-Mobile?
Please...please... help for answer & information. I'm very appreciate and thank you so much for explanation everything. :good::victory:
P.S. Sorry & apologize about my bad english
If S4 history repeats itself the ATT buyers will be stung with crappy locked bootloaders. Meanwhile the TMO device is pentaband and unlocked bootloader. Depending on battery life benchmarks the only sane decision is between TMO Note 3 and the international N3.
I posted a poll about carrier selection last week

Regarding your question, I opted for the T-Mobile version. Location will determine network performance...

But am i right?, Note3 International may not be able to use in T-Mobile LTE, right? thanks
Not to hijack the thread but does anyone know which one would be compatible for Wind/Mobilcity (Aws Canadian Market)?
Note 3 from At&Tor T-Mobile... in the past I believe T-Mobile phones are compatible because of 1700 and 2100 frequencies... however due to T-Mobile refarming (I have limited knowledge about it) and new frequencies.... would an At&t note 3 be modified to work on aws
????

To my knowledge, the international Note 3 does not have LTE radios. It has an octacore instead of quad but thats the trade off.

There are two models: one is the octa-core with no LTE. The other is Snapdragon 800 with LTE. However, both will only get HSPA+ on AT&T (anywhere) and HSPA+ on T-Mobile (in refarmed areas). The international LTE model won't get US LTE because we don't use the same LTE bands as they do in Europe.
In the US, if you're on a GSM network the best model to get is the T-Mobile model, even if you're on AT&T. It works 100% with AT&T and T-Mobile (refarmed areas or not) and has an unlocked bootloader.

I apologize to bring up an old thread, but I figured I'd ask it here as opposed to starting yet another thread.
Do you know if the Tmobile Note 3 is pentaband (i.e., like the Nexus 4/5)? I'm planning to use it outside of the US and just need to know if it can get 3G in European countries.
A poster above mentioned that the Tmobile Note 3 version is pentaband, but googling for the answer to this has yielded no solid results.
Thanks!
Here is the T-mo website:

here is the frequencies:

Yes. 850/900/1800/1900 on EDGE, and 850/[900 isn't mentioned but I assume it's there]/1700/1900/2100 for HSPA+. It should work fine.
EDIT: Confirmed 900 MHz is there. Look at the last post here: http://forum.xda-developers.com/showthread.php?t=2536817
Europe uses 900 and 2100 MHz for HSPA+ mainly. Both are supported. The AT&T version would also work fine, but the T-Mobile version is the best one to get because of the unlocked bootloader and additional AWS support (1700 MHz), which T-Mobile uses in the US. To me it's worth paying a little more for the T-Mobile version.

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

Trying to decide between ATT or Tmo version: How crucial will LTE band 5 (850mhz) be?

I am currently on ATT and was looking to purchase an off contract Moto X today but wasn't sure which one to get.
I've heard people say "Oh get the Tmobile version as it has bands for both and is unlocked"...
...but when I look at the specs for both I see the Tmobile version is missing LTE band 5 (850mhz)
Anyone here with technical knowledge of ATT LTE bands know how crucial 850mhz band 5 will be coverage wise?
Is it worth going with the ATT version to have that band for good LTE coverage long term?

its not the same, BUT
I think band 5 is not used in USA
Hard to say what AT&T will do in the future. From reading here there are a few places where AT&T is using band 5 for LTE service. AT&T would have had the choice of hardware when they decided to sell the Moto X and they chose the XT1058 and not the XT1053. Maybe they consider band 5 support important, maybe they just wanted a phone which didn't fully support Tmobile.
