[Q] Question On Bands For HTC One

I am needing a phone that will support all bands in the UK and for ATT in the US.
Will any version of the HTC One have the capabilities of what I am needing?
If so, is there any software tweeks that are needed?
Thank you for your time,
Dustin

A developer edition or an AT&T phone should work just fine right out of the box. The AT&T phone may need unlocked to work overseas but that is cheap or free Search sieempi unlock

So the ATT one has all the capable bands needed for US and UK market?
2G capabilities- GSM 900, GSM 1800
3G capabilities- UMTS 900, UMTS 2100
4G capabilities- LTE 800, LTE 1800, LTE 2600
Just making sure before I buy one.
Thanks

Will the Z3C work on T-Mobile US?

Just curious if buying it unlocked and using it on T-Mobile would be an option? Wanting to know if it'll work with the proper bands here?

Xperia Z3 (D6616) is supposedly headed to T-Mobile US as per reports. Not sure of Z3C though. I'm almost certain that you will be able to use its 2G if you bought it unlocked. It is better to check with T-mobile what 3G bands they use and then you can look up the spec sheet of Z3C to see if that band is supported.
I had once bought the Samsung Wave unlocked from abroad and used with T-mobile. Only 2G worked flawlessly. 3G was not supported.

Z3C is shown as coming soon on their US website. I believe all T-Mobile bands are supported except for band 12 which is only on D6616.

That's not true, the D6616 which is the T-Mobile version of the Z3 was customized for T-Mobile and has additional memory. It also supports different LTE bands than the other Z3 models.
The international Z3 Compact should work with T-Mobile but it will not have Band 12 LTE, and probably not work with WiFi calling or VoLTE.

Well, if you have a better answer than by all means you can answer his question. I was just taking a stab at it based off of good assumptions.

I don't believe T-Mobile is getting the compact version, check this http://developer.sonymobile.com/tag/d5833/ and notice the tags at the bottom, no mention of a D5816 which should be the model of the compact TMO version, if there was one, based on D6616 being the standard size version.

It looks like this phone will be compatible up to HSPA 21Mbit, GSM and Edge on T-Mobile. It seems to be missing the 1700/2100 AWS required for T-Mobile's 42Mbit "4G"
From T-Mobile: http://support.t-mobile.com/docs/DOC-6991
In order to work on T-Mobile's network, the device must support one of the following frequencies:
850 MHz (2G)
1900 MHz (2G or 3G / 4G depending on location)
1700/2100 MHz (3G / 4G or LTE depending on location)

So you'd end up with EDGE, GSM, and HSPA 21Mbit. Wikipedia does list Band 2 LTE on 1900MHz and the D5803 variant does support Band 2 LTE but I'm not sure if that make it compatible

I think you may be mistaken. It supports the T-Mobile AWS bands, which are 1700/2100, at least on the D5803 model, which is what the UK retailers are supposedly selling. It shouldn't have a problem getting full 42mbps HSPA+ on T-Mobile's network.
Additionally, LTE Band 4 is the T-Mobile AWS LTE, so it supports that as well.
The only T-Moble frequency it doesn't support is the new 700Mhz stuff they bought from ATT (LTE Band 12), but they haven't done anything with that frequency, and likely won't for another year or so.

Yea I completely glossed over LTE Band 4, whoops. I thought to support 1700/2100 AWS UMTS the phone would have to support both 1700 Band 4 and 2100 Band 4 (which it only supports band 1 at this frequency), but I may be mistaken. And I appreciate you setting the record straight if I'm mistaken in that regard. :good:

I can understand the confusion.
Sony, and possibly other phone manufacturers, don't generally seem to list 2100MHz(IV) seperately, likely since it's "bundled" with 1700MHz(IV) for the purposes of the AWS compatibility. One without the other is largely pointless (I believe).
So by listing 1700MHz (IV), they're indicating that it also supports 2100MHz(IV). As an example of what I mean, look at the official frequency listing for the Xperia Z2, which is my current phone.
D6503
UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1700 (Band IV), 1900 (Band II), 2100 (Band I) MHz
GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
LTE (Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20)
Notice how it also omits 2100MHz(IV) frequency, but it definitely supports T-Mobile AWS.
Anyway, The Z3 Compact is absolutely going to support AWS.

Thank you for not only the answer but explanation, have a :good:

Thank you all for this info. Guys. I am really tempted to purchase the z3t over the z3 but I was really worried about using LTE connectivity. I have never owned a sony phone, just my galaxy s3 so this is definitely something new for me and I am ready to try something new. I was tempted to purchase from handtech but I think I will wait a week or 2 to make sure. It is said to be available in 2 days. I want LTE, this would be my first LTE experience.

No need to be concerned.
The Z3C definitely supports T-Mobile's LTE bands, except for the newly purchased 700Mhz stuff from ATT (LTE Band 12), but I wouldn't expect to see that rolled out anywhere sooner than 8 months to a year, and then it's probably going to be present only in very few areas.
Honestly, I don't think Band 12 will be a concern for another couple of years, based on the speed at which T-Mobile initially rolled out LTE.

I have a Z3C coming for use on T-Mo in the states (going from GS3 as well). I almost didn't get it because of the lack of compatibility with LTE Band 12, but then I saw where the Band 12 coverage will actually be. Frankly, it doesn't cover my area, so I decided since it is compatible with all the other LTE Bands to go for it.
There is a great map at TMoNews that shows you just where the Band 12 coverage will be, but I can't post links yet.

I cant wait. My z3c will be here tomorrow... thanks for all the info.

[Q] Does Pure Edition support Fido/Rogers 3G/LTE bands?

I'm thinking of getting the pure in the US and using it up in Canada. Wondering if it'll work. I've heard mixed things about the LTE bands and some saying that 3G won't work at all.
Much obliged.

It will work perfect, 100%

Telus sells the XT1097, your looking at the XT1095 out the US just don't pick the AT&T model as it has a locked boot loader that seems cant be unlocked at all..... The Telus model, supposed to have the quickest updates... well thats a lie.... there is no update as of today... and no indication of when either...

I was able to buy a XT1095. I still haven't received it but now all I can think about is "What if I need to use the warranty for some reason?". Did anyone in Canada have to go through that?

I asked a similar question (but for Telus) on howard forums. This is the response i received o0vL
"Moto X - Pure Edition (GSM Unlocked with T-Mo SIM - XT1095):
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
UMTS/HSPA+ (850, 900, 1700 (AWS), 1900, 2100 MHz)
4G LTE (2, 3, 4, 5, 7, 17)
Telus Moto X Specs
4G LTE: (Bands 2, 3, 4, 5, 7,17, 29)
4G (HSPA): 2100MHz (Band I) / 1900MHz (Band II) / 1700MHz (Band IV) / 850MHz (Band V) / 900MHz (Band VIII)
Seems like the Pure Edition is missing band 29, where its available on the Telus version. Not sure if it will affect the LTE connection"

On another thread on this site, someone mentioned that the hardware is the exact same on the canadian model as it is on the pure edition model, the only difference is the firmware. So it seems to me that a radio flash might be required in order to receive the proper bands. I'd love confirmation on this, as I plan on using motomaker in the US to build my phone.

You can't actually change the modem files, you must you the original meant for the phone. The XT1095 supports all of the 2G,3G and 4G bands that Rogers/Bell/Telus/Fido/Virgin/Koodo/Wind/Mobilicity use in Canada. You don't need to do anything but insert your nano sim and possibly program the APN to get network data.

thanks for the reply Steve, so the lack of band 29 shouldn't be an issue? LTE speeds should be achievable?

[Q] Will a Hong Kong Data Sim work?

My mom has a Droid Turbo, and I still have my Droid Maxx. We are wondering if the Hong Kong data sims will be plug and play (since it's sim unlocked from the factory), I really have no way of testing before we go to HK. My other option is to buy 3 Moto G's as backups in case they don't work, since they're on sale.
Planning to grab a sim from three.com.hk
Specific APN settings would help, maybe the techs at the shop can help us too.

Never been in Hong Kong question is are the HK carriers GSM? if yes then you won't have any issues (I don't have turbo but used many verizon phones in europe)
hope that helps!

check the frecuencies of the phone and the frecuencies by the carrier you want to use on china, if they match you can use it.

If it is a prepaid SIM and preloaded with funds and a GSM carrier with bands compatible with the DT then it will work but as you noted, you are going to have to know the APNs too if you want to use data. The DT is GSM SIM unlocked out of the box. The frequencies are here:
https://www.motorola.com/us/smartphones/droid-turbo/droid-turbo-pdp.html
Bands
LTE Cat 4 (Bands 2, 3, 4, 7, 13)
CDMA/EVDO Rev A (850, 1900 MHz)
UMTS/HSPA+ (850, 900, 1900, 2100 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)
Carrier Aggregation (B4+13)
So as you can see, the GSM bands are 850, 900, 1800 and 1900. Then for 3G data the bands are 850, 900, 1900, 2100 and for LTE the bands are 2, 3, 4, 7, 13.

That is entirely dependent on the carrier. None of us know what carrier you are planning on using.

I'm using turbo in hong kong and no problem with all carrier here. Lte can be functioned normally on turbo.
Sometimes it might get no signal for a few seconds because the turbo jump to search for cdma signal.

Very small different then in terms of bands.
THANK YOU!!!
It seems I can purchase either then
Hmm.... although now I see there's a N920 model as well. Probably different LTE bands as well.....

Yes, first the N920C did get the marshmallow update, also your going to get Samsung pay, but your going to get carrier bloat ware homever you can disable it with package disabler pro. Also you get better reception in USA and Canada. N930I comes without any Carrier bloat ware, you have better reception in Asia or Oceania . Also you may get a bit better battery life (a bit noticeable).

Hey,
Just doing a bit of research. Wanted to get an unlocked version either the N920C or N920I so I can use it on AT&T.. I would get the AT&T variant but I hate carrier branded/modified software and additional bloat.. From what I'm understanding, either should be fine but the C variant comes with bloat correct? I've seen a lot of people using the N920I model and have had no issues and says it works great.. What carrier are you on?
