LTE Band confusion. - X 2014 Q&A, Help & Troubleshooting

So I just got this phone this week, and I knew it wouldn't have band 20 support from every single info page there is on the web basically, including official Motorola pages.
I was even considering switching operators when buying this phone..
My old HTC One M7 had Band 8, 800mhz, but not 900Mhz, so I never had coverage outside any city or at home.
Band 20 is 900mhz, and is the only band Tele2 Sweden has long range LTE on, which is nonstandard, everyone else is using band 8 for this.
But imagine my surprise when I DO get maximum LTE coverage, literally everywhere I've been.
So I'm properly confused, what does this thing support? Or did I get ridiculously lucky and got an completely unlocked device or what?
The about page says I have the XT1092.

There is already a thread for that, no need to open a new one : http://forum.xda-developers.com/showthread.php?t=2884337

[Q] Is the htc one a world phone?

Idk if I'm using the term right, but I'm with t mobile and I know that they will offer the htc one. But that's rumored to be towards the end of march. But appearntly Europe will be getting it the first of march. So my question is: will all carriers be selling the same EXACT phone? Meaning can I get a euro version when it comes out and use it on t mobile, and still get 2g,3G,and 4g (hspa+,LTE) ? I'm very anxious to get a new phone. I'm down to the htc one and the xperia z.
Yeah it's a world phone, it won't be in the market before 15th march. As clove.co.uk states that. IMO Better to get from your carrier if you don't want to face any issues with network. But if you want fast updates, it's good to purchase from uk.

Yes for 2g and 3g, not really for LTE in selected countries... And then I am certain that the LTE band will be tied down to that network provider. I will be amazed if this is not the case because HTC always does this, with exception of the HTC J-Butterfly (only in Japan), the reason behind this is that Japan law requires the phones to have world network support. The Sony XZ defninately covers world support on 2g,3g & 4g
We are in the same boat!

We are in the same boat. I am with Tmobile and have Galaxy S3, but as soon as I saw the leaked image of HTC One, I was instantly fell in love with it and I am surely glad they kept the design. It is the kind of design and material I wanted for a long time. Anyway, cut to the point, I pre-ordered from Clove.co.uk and expansys-usa.com. Whichever can ship it first will have my money. The reason I pre-order instead of waiting is it looks like it will be cheaper this way since I am buying off-contract. Tmobile's phone usually have much higher price than other carriers like ATT. Of course you can buy att one and unlock it, but it is illegal in USA now so that complicates things. Only thing I am worrying about is the compatibility with Tmobile's upcoming LTE network. Since I am living in Houston, TX, it is only logical to think Tmobile's next LTE market will be somewhere in TX if not Houston. But, I saw their LTE band is not the one supported by HTC One. (I saw this in one of forum here. Don't have the link) Tmobile maybe make LTE version of this phone like galaxy note 2, but then that will now complicates the battery life. So I am not sure if I want to have LTE version of HTC One when the battery is not user replaceable. Besides I am more than content with current Tmobile's data speed as HSPA+ in houston area. So my point is if you are sure you will get this phone, pre-order seems the fastest one so far. I picked silver one BTW.
It might sound lazy but I'm actually really confused about the bands for the different networks in my country. I want to get an HTC One but I'm not sure if I will have 3g on my company "VTR", this company is from Chile in South America and I would be really thankful if anyone can give me a hand on this:
The website of the company is: http://www.vtr.com
Please, give me a hand on this as I'm really confused and I have been searching a lot to get more information. This is what I've found:
http://en.wikipedia.org/wiki/UMTS_frequency_bands
VTR is at the number IV AWS 1700
Also I found this:
http://www.telecompaper.com/news/vtr-nextel-win-3g-licences-in-chile--690358
VTR, Nextel win 3G licences in Chile
Chile's telecommunications regulator Subtel has granted mobile operators VTR and Nextel spectrum for provision of 3G services. The tender covered three blocks of 30 MHz in the 1700/2100 MHz frequency band. Nextel won two out of three blocks of spectrum up in the 1700/2100MHz frequency bands, while VTR won the remaining block. Nextel's total offer for spectrum blocks B and C reached USD 14.7 million, while VTR won block A with an offer of USD 3.02 million. The new licences aim to boost competition on the Chilean mobile telephony market, currently divided among Entel PCS, Movistar and Claro. The Chilean telecoms market currently reaches 15 million customers. According to Rene Cortazar, minister of transport and communications, the two licence winners have a maximum of one year – that is by the second half of 2010 – to complete their 3G networks deployment across the country.
VTR 3g frecuencies: 1700/2100
I currently have an HTC Desire HD, however, I'm unable to use 3g with my device. Please help me confirm that the ONE will work on this network, else, I will have to change my network
A little bit more information can be found here:
http://www.apecdoc.org/site/chile/2009/06/11/vtr-sets-up-vtr-movil-to-bid-for-3g-licence-chile/
Thank you very much for all your help
The phone doesn't have support for the 1700 band, but will work on the 2100 band offered by your provider. The biggest problem you face is what is the difference between bands for VTS, typically network providers will offer a faster network and or more coverage on one of their bands. If in Chile this is the 2100 band you are away laughing.
Just had a look at the specs of your HTC Desire HD and the news is bad.The new HTC one will the same as your previous phone on that network.
I don't understand what you are saying about your phone not on 3G, the 2100Mhz network is 3G, however it would seem that your provider is offering it's premium higher speed services on 1700Mhz.
I suggest you go to www.gsmarena.com then search for brands of phones that have 1700Mhz radios. So got to say HTC, and under bands select 1700 then filter, you will find only 13.
After checking this, scrub the above and only use it as a super rough guide. Because it states the Sony XZ as 1700Mhz, but no Sony website claims this that I can see.

Thanks a lot, I hope the phone gets 3g, however, I know that Entel (another company in my country) will offer the HTC One on the third or fourth trimester of this year and it might allow LTE connection. If that's the situation, I might consider changing my mobile provider
I really appreciate your answer.
Thank you
its not worth buying the international version anymore if the US carrier versions are the same as the international one..
LTE is moving forward and HSPA+ will stop development in a few years once T-Mobile switch to LTE
im sure the T-Mobile version will be the same as the rest with LTE ready
yes i think only small 4g lte variations

Not true, there is three LTE variants in the US depending on the band eg provider The best US is AT&T which covers all of US. It all comes down to what bands your country decides to go with on LTE.
So it is a toss up between AT&T or UK model depending on your LTE band requirements.
HSPA/WCDMA:
Europe/Asia: 850/900/1900/2100 MHz
GSM/GPRS/EDGE:
850/900/1800/1900 MHz
LTE:
EU: 800/1800/2600 MHz
US (AT&T): 700/850/AWS/1900 MHz
US (TMO): 700/AWS MHz
US (Sprint): 1900 MHz
Asia: 1800/2600 Mhz

No worries, it's my pleasure.
As I said before your current HTC phone should be 3G on your network provider because 2100mhz is 3G.
ANd most unfortunate for you in South America is that they use such a mix of LTE bands covering most of the LTE spectrum, in this case you are better off with the Sony Xperia Z, which covers almost all of the used LTE bands.
I have used Claro in South America which has great coverage, but bad customer service, but I guess you always get that with the big players.
Hi,
I'm on a Canadian provider that has a hard time with getting good phones. I'm on Wind mobile and actually those who are on Mobilicity are in the same boat. When HTC One X came out it wasn't available for Wind or Mobilicity, when HTC One X+ came out it wasn't available either. Only the cheaper versions of One S would work on it, other ones didn't support the bands. I can see that for Canada none of these providers are listed to carry HTC One. Does it support the bands that Wind and Mobilicity operate at? Will it work on it? They operate in AWS

Why don't you go back one page and read, I have posted all the bands supported by the phone. AT&T will be your best option for coverage
I've got a bit of a similar question about where this phone will work on a specific network. If I buy an unlocked CDMA version of the HTC one, can I just drop a Verizon sim card into it and use the phone on verizon's network?

There is no CDMA version, and cdma devices do not use sim cards.

only reason i bring that up because the ONE will be on sprint's network which is CDMA, along with the fact that i thought verizon 4g phones used sim cards ( my pantech marauder loner phone had one). thanks for the answer
Hello
Do you know if the European version of the HTC One will be compatible with the American 3G network (ie : AT&T)...
Because last summer I was in USA and with my old HTC (not compatible with AT&T 3G), I was only able to use 2G networks for internet and it was very very bad...
So I'm asking !
Many thanks in advance for the answer !!! :good:

[Q] Sony Xperia C6903, LTE on AT&T

I emailed GSM Nation to see when they would received the C6906 because I want to use LTE on AT&T. They sent me a reply saying that many of their customers use AT&T, and have been reporting LTE working.. Are they just blowing smoke up my ass? If not, is there a way to see what bands are active in each cities?

i'd be cautious about buying the C6903 and using it on AT&T in the U.S. I had the international version of the Z earlier in march C6603 and i never got LTE on that phone, only HSPA+. I used this phone in Minneapolis and never saw LTE. I also did a road trip from Pittsburg to Orlando and never saw LTE on the way anywhere. Also used in Miami without LTE.
I believe its important to have the 700 band if you want to see LTE on the AT&T network on a device.

You can use the 6903 model on AT&T, I'm using the Z1 on it right now. But to get LTE support you are correct, you need the 700Mhz band which is in the 6906 model.
Bleh, I had the same concern and called ATT and asked. The guy told me this.
ATT uses 700-1400mhz spectrum. meaning 700 though, not and. So any device that supports bands "in that range" will work fine. Was he misinformed, or is that right? When is the damn xxx6 model coming out anyway?
I'm using the xperia on ATT right now no LTE but I do get hspa+ which is fine (is a 50mbps connection REALLY needed for a phone?) Anyways there is a chance that LTE may work in the US because ATT is rolling out and already has the 1700mhz band in a bunch of cities: Phoenix, Raleigh, San Juan, Los Angeles, Las Vegas, Oklahoma City, Dallas, Chicago, Charlotte, Athens, GA and College Station, TX. The Nexus 4 people were reporting that it works but not sure about Z1. I'm not from any of these cities so i can't confirm if its working. Maybe someone can?

When it's been shown to give better battery life thanks to race to idle advantages? Absolutely.
http://www.anandtech.com/show/6330/the-iphone-5-review/13
>The non-LTE phones see a sharp drop in battery life. At least at 28nm the slower air interfaces simply have to remain active (and drawing power) for longer, which results in measurably worse battery life.
This doesn't work on slower LTE networks like verizon, but for us on ATT we can get better battery life while enjoying faster speeds. Note that in that graph anandtech measures HSPA+ as "3g", as it is 3g, despite ATT and verizon's marketing. I make this distinction to prevent people from thinking they are testing the older 1.4mbit or whatever network they used to use.
I'm probably going to get the Z1 without LTE functionality in my area anyway, because at the end of the day I'm without a smartphone right now (my HTC one got washed with my clothes and doesn't do much other than vibrate when it's plugged in now) and don't want to wait for Sony to stop being lazy and put out the model with 700mhz LTE.

The only reason it improves battery life is because its take you less time to download things which is a given. If you're constantly downloading extremely large files then maybe you need it, but for me not so much.

The answer is yes, they are blowing smoke up your ass. In order for a phone to get AT&T LTE, you need Band 17. That is their primary LTE band. They also supplementarily use Band 2, 4, and 5 in select cities where they don't have Band 17. Similar thread in the Z Ultra forums, which have similar models which might clarify this more if you need more details.

You did not read the source I linked I think. It shows web browsing, not downloading massive files. LTEs speed and therefore race to idle advantage applies to more than just downloading large files, it shows battery savings in normal day to day use, from things that drain quite a bit of battery like browsing to smaller things like syncing gmail accounts.

What speeds are you guys getting on ATT with the C6903? If the C6906 isn't shipping anywhere by midnext week I'm going to order the C6903, I've been android less for 2 weeks now, I'm going crazy. I don't use my phone as a hot spot or for file downloads, so I don't need crazy speeds which I don't even get anyway LTE wise in my area, usually 22mbps max and on average upper teens.

I'm getting 8.22 Mbps down and 1.13 Mbps up with full bars on AT&T right now. I'll do a few more tests to check for consistency.
EDIT: Just ran another test and I got 9.21 Mbps down and 1.13 Mbps up.
I'm full bars on my Lumia 920 here at work, only getting 5/0.6 on LTE so I guess C6903 would do just fine. I only ever get good LTE speeds at home, but I use my phone on my wifi connection there so it's not very useful. Thanks!
I received my Sony Xperia Z1 from GSM Nation yesterday and can vouch for the fact that the 6903 model will in fact NOT work with AT&T's 4G LTE network. I live in New York City too, if that means anything. I spent the entire afternoon trying to connect to the LTE network. Instead, I was able to connect to the 3G (HSPA+) network and that's it.
I am very unhappy about this and will be returning the phone to GSM Nation immediately. I love LTE speed and did not know that battery life was affected by it too (thanks for that youwonder!) so I'll patiently wait for the 6906 model to be released. Does anyone know when that might happen? I can live with my old Galaxy Note II for now I suppose. Agh!

Heres the message I got to the query, about at&t lte from GSM Nation, also asked them about 6906. Edited out private stuff.
"at&t's main frequency for LTE is 700 mhz so the 6903 working is really upto where in the US you live and that is unfortunately not information we would have. It is certainly limited markets for 1700's but these are just reports from customers from our followups.
Regardless we do not advertise it as compatible with at&t due to it being limited markets. And would advise that customers purchase it for use with at&t LTE at their own risk. The c6906 model traditionally comes to carriers first so that would be the safest bet at this time if your looking for at&t LTE. It should be available soon in the US."
seems pretty clear cut.
Sony Xperia ZL C6503 also no LTE

PMFJI. I own the C6506 (Sony branded, carrier unlocked) which support a wide range of bands including LTE IV and LTE XVII, both of which are used by AT&T. In addition, I get PCS 1900 which AT&T is rolling out.
I get NO LTE service and I was told this is by design. If you do not own an AT&T branded phone, the network will not permit you on the LTE network. I am provisioned for LTE but I cannot get even 4G.
This was not explained by anyone and it took me a number of support calls and escalations to learn this. I believe the only way to effect change on this rregressive policy is for people to complain. There is no reason to penalize BYOD customers who choose not to own an AT&T branded device.
My device specs for LTE: 4G Network LTE 700 / 850 / 1700 / 1900 / 2100 - C6506

will European z3c work fully on AT&T or should I wait for US version?

I see that the Sony mobile US site has the z3c listed as coming soon. Is it best to just wait for that to come out or will the European version fully support all of the AT&T bands? I'd hate to import a phone and not get the best reception/internet.
I know it was suggested in another thread that it would work with AT&T but then there was some confusion in another thread about the phone possibly missing 1 or 2 bands. Any help from an expert would be greatly appreciated.
mazyou tube
I know Sony's white papers have been wrong in the past (Z1 Compact with glass back, grrrr ) but the one for the Z3 Compact D5803 has 4G bands Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20.
I've had a hunt around for AT&T's 4G bands but this seems a but trickier as it seems dependent on region, going by wikipedia it looks like the main bands are 2, 4 and 17 which are all supported by the European version per the above. It probably doesn't help that I'm not from the US and I don't have enough posts to add the URLs, sorry.
I feel like I remember reading back in the day that some companies used bands of the same frequency that weren't cross compatible. It's always made me nervous about buying non US phones. However my info could be wrong.
When I was in the states, I got a AT&T sim card. My phone definitely says that it has the lte bands. Still, it only displayed h+ while I was there. I did not bother to go back to the store and check because the speed was very good anyway. So maybe it's because the bands are different or it was working on 4g but just not displaying it, I don't know.

AT&T must provision your sim for LTE otherwise you'll only receive 3G even if the phone is capable of 4G. Usually they do this based on the IMEI of your device and if it's a non AT&T phone then it won't appear in their database as LTE capable. There are ways for them to manually configure the sim for LTE by contacting support.
The UK model D5803 definitely supports AT&Ts LTE on bands 2, 4, and 17.
Does AT&T have more bands than 2,4,17?
I found when googling AT&T LTE bands that they apparently have also started to use band 5 (850mhz) but that's still supported by the Z3 compact. This was both on AT&T's forums and howardforums but I'm not sure if AT&T need to do something else to enable LTE support on that particular device. I think my own network (3 UK) has to do this as it took a few months for my unlocked Moto X to pick up their 4G network.

Refer to the manufacturer's website to verify your unlocked device works with a SIM card on an AT&T GSM network frequency:
• 3G UMTS network 850/1900MHz bands
• 4G LTE network AWS / 700 / 850 / 1900MHz bands

AWS (1700/2100MHz) is band 4 (Blocks A, B, C, D, E)
700MHz is band 17 (blocks B, C)
850MHz is band 5
1900MHz is band 2
The overwhelming majority of AT&T LTE is on band 17. Bands 2 and 4 are used for additional capacity in some markets and/or some rural/smaller market coverage. I'm not sure they've rolled anything out on band 5 yet, but even so the Z3c has that covered.
OK,
thank you very much for the additional research. It seemed like that was the case but I don't trust my own opinion since I haven't done any real looking into this type of stuff in like 4 years.

To answer your original question, as far as we know there is no US model of the Z3c, only the EU D5803 and Asia D5833. If Sony sells it unlocked in the US it will probably be the D5803.
In preparation, hopefully I'll have it in a week.

Subscribing since I'm very interested in this phone and my service provider is AT&T
Works great. I live in both NY and San Francisco, and I get LTE everywhere on AT&T.
I imported the D5803 (EU) model through Expansys.
Yes. Just make sure to get the d5803 model.

p7-L11 -- can anyone provide the specs?

Hi My telco Optus (here in Australia) is now advertising that this phone is capable of their full 4g band coverage: 700/1800/2300/2600MHz
I went in and had a look at the box, and see this phone is actually a new version the 'L11'. I can find brief mentions of the p7-L11 it online, but I can't find the exact specifications of it's 4g frequency reception anywhere. I want to confirm this before i buy it. can anyone help?
cheers,
Charlie
Ha I had the same question last night so I googled and could not find anything on the 700mhz band.
Purchased the phone today and I can confirm that it is running band 28 700mhz as that is the only 4g coverage I have at my place here in NZ.
I know optus uses band 28 aswell I can not comment on the other 4g bands yet.

No more 4G on T-mobile network on unlocked HTC One M7 (originally an AT&T phone)

Living in NYC area. Using an (AT&T) HTC One M7 unlocked on T-Mobile network. After almost 2 years of 4G capability wherever there is generally T-Mobile service capability (i.e. NYC area and some other metro areas, etc.), as of Sun/Mon July 9th/10th, I stopped getting 4G anywhere and everywhere. Since July 9th/10th, I've been in Queens, Manhattan, Brooklyn and maybe Nassau County. I've also been in the Fort Lee, NJ, Newark, NJ and Jersey Shore (i.e. Bradley Beach, Red Bank, etc.) areas as well as in between those areas as I've driven to all the areas listed above. I will add that call audio quality has been very poor with plenty of dropped calls, also since approximately July 10th.
T-Mobile has given me a back and forth and contradicted itself multiple times, but I gather the gist is that there are network updates that supposedly make this phone not be able to get 4G on T-Mobile anymore, at least for the time being if not forever. Any workarounds possible? For reference, I do not believe that the phone is rooted.
Same phone, similar issues....
I can't say for sure where you are, but for past 3-4 months in the San Antonio area, T-mob has been making a lot of changes to modify their towers to accommodate their new LTE Band 12 (900 MHz?). Unfortunately, our ATT m7s won't pick up this frequency, or the AWS 1700 freq. either. As I understand it, these 2 frequencies will be vital to T-mob's future network expansions.
Back in May, I finally took the plunge, and rooted my m7. Doing so allowed me to install the latest compatible T-mob radio, along with getting my Hotspot out of ATT jail. The AWS 1700 band IS available in our phones, but its deactivated in the ATT version. There was no LTE Band 12 when our phones were made, so that option is out. The One m9 is the first HTC One that is Band 12 capable.
Basically, if you're planning to stay with T-mob, your best option is the m9, or some "lesser" phone (LOL), which supports ALL of T-mob's frequencies.
