Unlocked version of M8 from HTC - AT&T HTC One (M8)

Hello.. I am currently in Taiwan on business and was curious if I bought the unlocked version of the m8 from an HTC store here, would I be able to pick up the at&t LTE bands back in the US?
I'm pretty sure the hspa+ works but not sure about the lte.
Thanks!

LTE MIMO; GSM/EDGE: Quad-band (850/900/1800/1900 Hz), Class 12; UMTS: Tri-band (UMTS 850/1900/2100MHz), HSPA+Category 14xx (HSDPA 21Mbps/ EDCH 5.7 Mbps) this is what you would need for at&t LTE. I also have the developer edition but it came from HTC U.S.

Ok Thanks for the response.. I'll have to see if the version here has those spectrums on it

Gsm EVO 3d will it work on ATT 3g bands

Considering changing my inspire for the EVO 3d. Can anyone confirm it working in ATTs 3g bands.
Sent from my Desire HD using XDA Premium App
I assume 2g, gsm, will work because they use the same bands for that, 850 and 1900 but 3g, umts, they use different bands. Source
But don't take my word for it.

from what I can see the Euro version only has 900/1700/2100 MHz but Rogers is supposed to get it in Canada in August with 850/1900/2100 which is perfect for AT&T!

Sounds good. Will wait to see what Rogers gets. And get some hands on info. Played with a Sprint EVO 3d and was amazed really hope it supports ATT 3g bands.

Gt-I9300 international on U.S. T-mobile

Just curious, I have the international and I am on T-mobile in the U.S.
Will the I international ever be able to attain 4G Speeds on T-mobiles network? For instance once quad cores become the norm in phones (like they are on the verge of doing).
Or would I be better off selling and getting a T-mobile g3?
Thanks in advance.

well, as far as i know by end of this year we will be able to use 3g or hspa+ but for now i am sticking with 2g
or just change your mobile network, get straighttalk or att

Ok. 3g would be great. For the most part that is what is in most areas anyway. I just wasn't sure if it was our phone that didn't have the right radios or if it was T-mobile/other carriers that didn't have the right modems for our exynos.

International S3 does not have 4G chip in it
The max network speed that could be available with an international S3 is 21Mbps HSPA+

And is this based off of what's available now or what will be available in a year?

T mobile AWS Spectrum

So the AT&T LTE version of the One X+ has AWS 1700 MHz for LTE. Is it possible to flash a different radio and access the Tmobile 1700 HSPA+ network? The new Tmobile plans are certainly tempting.
Great question. I am thinking the same thing. ATT cost too much.
S-off is needed to flash radios if I remember correctly
Sent from my Viper One X+
Is anyone in one of the 8 Tmobile LTE launch markets? Their LTE is on 1700 I think, and the HTC page shows LTE frequencies being supported on 1700 for our phone. So even if we cant do HSPA+ 42, maybe we can get LTE? Im in atlanta so I cant test that.
Guess no one has tried

LTE on T-Mobile

Is there anyway to use T-Mobile 4g service on the Rezound once you have it globe?
Sent from my SGH-T889 using Tapatalk 2
Inherently, no. Our bands we use is 700 (LTE), 1800/1900 (CDMA) and 1900/2100 (for GSM I think).
most GSM networks run 850 for LTE and another MHz band for HUSPA+ that our phone doesn't run.
In other words, without the possibility of screwing up your radio, right now, all you would get is edge.

LG G2 Tmo or ATT: Which has more bands?

Hello,
ATT user here currently on Note 2. I'm planning on buying G2 off contract and I'm debating between ATT and Tmo. Verizon is out because although it has SIM card it won't access LTE on GSM.
I understand that Tmo has all the bands ATT does and more, is that true? Would that explain why it's $600 on Tmo site and $580 on ATT? I looked at their respective wiki's and product page but they don't provide consistent descriptions. If anyone can help it'd be greatly appreciated

I know the Moto X has more bands for Tmobile's version vs. AT&T. I wouldn't be surprised if the same is true for the LG G2 as well
From Wikipedia:
D800 ZNFD800 AT&T 850/1900/2100 LTE 2, 4, 5, 17
D801 ZNFD801 T-mobile 850/1700/1900/2100 LTE 2, 4, 17
TMO supports AWS, unlike AT&T. AT&T supports LTE band 5, unlike TMO.
this doesn't answer the OP's question, but, i have a sim unlocked att G2 and i can get 4G and 4G LTE service with my T-Mobile sim/account. coverage is not as good as at&t in my location.
Awesome, thanks Sacrosaint!
I went through the LTE wiki, it seems like 5 is not that prevalent. Seems like the Bahamas, South Korea, Belize...it seems to me that Tmo would be the better choice, no? What with its use of the AWS spectrum and all. I'm still on ATT for another year so I won't be jumping ship yet (by then I guess the G3 would be out...)
The only concern is whether ATT's LTE-A frequency can be grabbed by the Tmo version, whenever it launches...

I tried att lg g2 with my tmobile SIM it never gave me 4g/lte returned it back and got the new one from tmobile. Everything Is working fine on att I could only get 2g/edge and that is a known prob the att lg g2 does not have 1700 aws band for tmobile.

Hmm. So you have Tmo plan and the ATT model didn't get you any LTE at all?

Not sure of the truth to that. Verizon, T-mobile, and At&t all support LTE band 4 which is AWS 1700. It might be more likely a carrier lock that prevents you from getting full coverage?

LTE band 4 is AWS and supported by AT&T. The frequencies listed in the wiki are for 3G/UMTS coverage which AT&T doesn't support AWS.

I'm in AZ and actually purchased LG on day one that AT&T sold it. They did not want to sell out-right so I got a prepaid service and told them I would not activate until next month...Manager looked at me like I was a terrorist. Went outside and on my then GS4 went to an unlocker site and SIM UNLOCKED LG in about 25 mins. I tried two different APNs and one seems to be best as I have LTE mostly all over the valley!
SUMMERY
-Got phone before anyone else on TMObile
-Got phone at least $60+ cheaper W/taxes
-I can use the WIFI free hotspots of AT&T, always on the road...
-At work my LTE is 27-36mb down compared to 12on att co-workers, and Verizons 17MB on a different co-worker!
-At home my signal is a tiny bit spotty, oddly is only in my room ge 1-2 bars H+

Ah thank you for the clarification. So the Tmo version will get 3G coverage in areas the ATT version will not?
I called Tmo yesterday. They won't ask me a phone straight out, I have to buy a one month plan . Now I see why the prices on eBay are higher than the $600 listed. Just looking for a store that has the white model.

Oh I totally forgot about the wifi thing...is that an ATT service that works with our ATT plan, or will it know I'm using a Tmo phone and not let me connect? Not a big deal since I have 2 GB and always come under each month but itd be nice to have.

Well, since t-mobile's 3g/umts is predominantly on the AWS 1700 band, utilizing a t-mobile SIM on the at&t model will result in sparse coverage for 3g, short of roaming. I understand t-mobile has built out some of their 3g on 1900 as well so that would work for you. Based off of frequency support, I would say the t-mobile version is the better one to unlock and potentially use between at&t and t-mobile networks. LTE band 5 support doesn't buy you anything domestically.

Thank you everyone for your input . Guess Tmo it is.
Though...One wonders what their software support is like...I read that since they do wifi calling they're updates have to go through extra approval above and beyond the othercarriers because they have to deal with the FCC?

Here in the Bahamas we don't have LTE yet, but we're planning on covering the same spectrum as AT&T, bands as well.
no AT&T LTE on T-mo G2
I have an unlocked T-MO LG G2. I recently swithced to AT&T (which only benefit is greater coverage area bc HSPA+ is way slower than T-MO) however my phone is not showing 4G LTE only 4G. when i searched for networks the very first time it listed AT&T LTE but would not let me connect and now it doesn't even show up in the network search. Does the T-Mo variant block a certain frequency used for AT&T LTE ??

Incorrect. T-Mobile devices support ALL AT&T and T-Mobile bands, except LTE Band 5 (used by AT&T in a few rural areas). What's wrong is AT&T turns off LTE for non-AT&T devices. You have to call them up and give them the IMEI # of an AT&T-branded device (even if it's not yours and even if your SIM isn't in it/you don't plan on using it). They don't check after that.
