I've already preordered my Sony Xperia ZU from atgsm.com

Although it's backordered right now and I have to wait another week for it to arrive, ( SUCKS because I even got FedEx 2 Day Shipping! ): )

I can POSITIVELY and SURELY CONFIRM that:

C6833 Works on all networks INCLUDING 4G LTE for T-Mobile as this uses BAND 4

C6806 Works on all networks INCLUDING 4G LTE for T-Mobile and AT&T

C6802 Works on all networks EXCLUDING 4G LTE

Hope this clears up any confusion. The International version of the Xperia ZU will work on all networks that have 4G LTE as well EXCEPT AT&T'S, presumably because it does not have the supported band. (I cannot confirm but am 99% sure) The North American (US) version will be slightly cheaper by $20-$50 depending where you order it from. The only true benefit of this (besides saving money of course) is the ability to connect to AT&T's 4G LTE network. Other than that, they are both the same. (EXLCUDING C6802 which does NOT support ANY 4G LTE speeds)

If you don't want to wait until after October 14 like me, go ahead and get the international version. Some websites have good deals and you might be able to get it at an equal price OR cheaper compared to the C6806 if you look wisely and do your research.

Personally, the international version is the way to go if you aren't on AT&T's network because if you ever go somewhere outside of the US, you can still use prepaid phone plans or such and access the internet. For such an amazing device coming with a premium price tag, I'd like to be TRULY mobile with my phone!

PLEASE stay tuned as when my Xperia ZU arrives I'll do a live video of me taking off the Anti-Shatter Film as some of you wish to do so. (Same here) I'll also post up some pictures of the cases I have and screen protectors I'll be using (SPIGEN TEMPERED GLASS COMING SEPT. 30!) and various tests (NOT the usual ones you see of benchmarks and such, but rather more interesting ones like size and everyday practical use)

If you guys have any questions just feel free to ask, we're a community here so let's see what valuable knowledge we can offer!

[Sony Xperia Z Ultra] LordManhattan:
Correct. The C6833 has octaband LTE support. The bands on the Z Ultra (C6833) are 1, 2, 3, 4, 5, 7, 8 and 20. The big additions here are 2 and 4 which will open up the Z Ultra for broad use on major LTE networks in North America. AT&T have band 17, Verizon use band 13, Sprint use 25/27 and US Cellular operate on 12. Only T-Mobile have stayed ‘open’ on band 4. The other main carriers mentioned do also use bands 2 & 4, the unique bands allow them to lock down devices they sell to their own LTE networks, but 2 and 4 are open.
[Sony Xperia Z Ultra] ewatt74:
So that means you could'nt use the c6833 on At&t LTE network then.
[Sony Xperia Z Ultra] ij0rgei:
I can confirm this to be the case. I am currently running the C6833 on ATT and an unable to get the LTE to work. I have called them and checked and they have said by not having the 700 band, that is whats keeping me from accessing their LTE network. Right now all I am getting is HSPA+ on their network and it works pretty well. It has been a PITA getting all the network settings to work all at once but I think I have it all good now, so if anyone is trying to use ATT and having problems, I might be able to help.

One question I do have is that most LTE phones that are made specifically for ATT have LTE 700mhz band 17/2100. the C6833 has the 2100 band, so my question is why cant we access the LTE network using that band since we dont have the 700mhz?
[Sony Xperia Z Ultra] ewatt74:
I have the Sony Xperia Z Ultra 6802 and I'm useing it on At&t. But I will be getting the 6806 so I can have the benifit of LTE.
[Sony Xperia Z Ultra] UserDemos:
You can't use it on LTE because 2100 is Band 1. The US does not use Band 1 (2100) because Band 4 (1700+2100) uses the 2100 for its downlink, therefore it is already being occupied. Make sense? Band 1 (2100) is something one sees mostly in Europe/Asia.

AT&T uses Band 2 (1900), Band 4 (1700+2100), Band 5 (850), and Band 17 (700). The majority of their network currently runs on Band 17. Without Band 17, you will not be able to access their LTE network in most places (I can only think of 3-4 places where they are not using Band 17 due to spectrum constraints).
[Sony Xperia Z Ultra] djjoonie:
Can anyone confirm c6833 will work on tmobiles 4g lte? I am very confused now..
[Sony Xperia Z Ultra] clubtech:
Yes it works on T-Mobile LTE. Using it right now.
[Sony Xperia Z Ultra] nihal1983:
can you please explain how

I have the same but no lte shown.plain 4g
[Sony Xperia Z Ultra] Purple_Clouded:
Normally you will NOT see a LTE logo unless yo do some time of root or customization outside o the stock Sony UI and launcher that came with the phone. (I cannot confirm but so far with my recent phones, this has always been the case.) The only real possible way of proving that you're on LTE from T-Mobile is by getting an app and clocking your internet speeds.

Regardless, if you're satisfied with the speed of your data connection and the lightspeed of the Sony ZU, there's no need to bother. (Unless of course you feel conscious of shelling out the extra 50 or so dollars.)

Rest assured, my ZU C6833 will be coming in this Friday and I myself am on T-Mobile. I've heard time and time that everyone has been able to connect to their respective 4G LTE networks with ease, and combined with the speed and finesse of the phone it's a breeze to surf the web, play games, multitask etc. I hope that you're satisfied with what you have! It would be a shame if you device was faulty! (Let's hope not!)
[Sony Xperia Z Ultra] UserDemos:
Not sure what's confusing. Learn what bands your carrier uses and compare them on the spec. sheet.

T-Mobile uses Band 2 (1900) and Band 4 (1700+2100 or AWS) for HSPA+ (a.k.a. 4G) and uses Band 4 (1700+2100 or AWS) for LTE (a.k.a 4G LTE).

The c6833 according to Sony supports Band 5 (850), Band 7 (900), Band 4 (1700+2100 or AWS), Band 2 (1900), and Band 1 (2100) on HSPA+ and Band I (2100), Band 2 (1900), Band 3 (1800), Band 4 (1700+2100 or AWS), Band 5 (850), Band 7 (2600), band 8 (900), and Band 20 (800) on LTE.

Therefore, the 2 HSPA+ bands and the 1 LTE band you need for T-Mobile are on the c6833. It will also work great internationally. If you have AT&T though, you will not be able to get LTE and need the c6906 model.
[Sony Xperia Z Ultra] djjoonie:
Thank you for the confirmation.
[Sony Xperia Z Ultra] cholepuree1:
Just make sure the apn is set correctly. I get LTE on US T-Mobile.
[Sony Xperia Z Ultra] nihal1983:
Can you please share the apn and what do you see under the mobile networks.I see 4g cdma etc.
[Sony Xperia Z Ultra] cholepuree1:
Here you go!
[Sony Xperia Z Ultra] nihal1983:
I don't see the lte option in networks. I added the apn manually
[Sony Xperia Z Ultra] nihal1983:
4g not lte for me
[Sony Xperia Z Ultra] cholepuree1:
It's possible that it's a fremont thing. When I had my Note2, i rarely got LTE in fremont, but always did in Irvine. I'll be in fremont this weekend, and I'll check it out for you.
[Sony Xperia Z Ultra] nihal1983:
thanks

I have an t-mo s4 and i get lte, funny thing is i get lte speeds no logo shown or in the networks shows 4g not lte
[Sony Xperia Z Ultra] ruebenhejja:
I have the same APN settings on my c6833. I get LTE on T-Mobile in some areas (San Diego, California) but if I go somewhere there is no LTE, I get no data. It's like the phone doesn't want to switch to HSPA+ or anything else if there is no LTE. Do I need multiple APN's or does anyone know how to fix the data being either LTE or nothing?

Edit: I changed the "Bearer" to "Unspecified" instead of "LTE" and now it gets H+ but no LTE... Weird...
[Sony Xperia Z Ultra] nihal1983:
i had an epac apn

when i inserted my sim it downloaded an epac.tmobile.com apn, i manually entered the fast.t-mobile.com apn after seeing it from my dads note2. mine does switch from 4g to h+,h, if i dial and press *#*#4636#*#* it does show me that it indeed is lte
[Sony Xperia Z Ultra] SwayProductions:
im thinking of buying the c6802, anyone know how the speed would be on at&t? or should i just wait for the LTE version? im just really inpatient, i want this phone ASAP!
[Sony Xperia Z Ultra] Purple_Clouded:
Don't bother getting the C6802, there have been numerous issues I've read about for that specific version, although many of those problems could also occur to other models of the XZU, it's wise to go ahead and get the more recent and updated LTE one.

If you can't wait, just go ahead and grab the C6833, it can hop on AT&T's 4G network but NOT LTE, I repeat NOT LTE. The US LTE version that works on all the carrier's respective LTE should be coming out October 14, the wait is sure worth it especially if you're gonna pay big bucks for a phone like this, my C6833 is coming tomorrow and I thought long and hard before ordering the C6802, didn't want to get stuck with HSPA+ speeds on a phone that had the latest and greatest processor to offer lol. Hope you can make your decision soon and be happy with it!
[Sony Xperia Z Ultra] SwayProductions:
can you tell me about the issues? also, im probably gonna be on wifi most of the time since im at work most of the day, will the c6802 work on AT&T 4G?? i really appreciate it, im just really excited for this phone, been waiting since its been announced and i finally have the money!
[Sony Xperia Z Ultra] E90 Commie:
I have been a C6802 owner since the beginning of August and there has been no issues with it. It works perfectly.

Some users reported light bleed from the screen but it is just to replace the device if that would be the case.

Otherwise, the C6802 works great. In my case, I just don't care for LTE since I don't see any US data plans that are optimum for high quality streaming (the closest would be T-Mobile and their unlimited plan) and the HSPA+ speeds I have is more than satisfactory.

Without the ability to stream (because of data caps), I see no reason to get LTE yet. The lack of VoLTE is another reason.

On the other hand, for those buying the Ultra right now, it can be a good idea of getting the C6833 or C6806. When I bought mine, the only version was the C6802 and I decided not to wait almost two months for LTE (that I can't stream with because of the caps).
[Sony Xperia Z Ultra] SwayProductions:
Thanks for the info, but is there a difference between the c6833 and the c6802? im gonna be using it on at&t..
[Sony Xperia Z Ultra] E90 Commie:
The only difference between them is that C6833 has LTE and C6802 HSPA+.

Otherwise, it is the same device. Some C6802s are shipped with the MSM8274 without LTE radio or MSM8294 with LTE radio (but deactivated). The C6833 has the MSM8294 with LTE radio - always of obvious reasons.

Usually, devices undergo changes/improvements to their hardware during the production run but that doesn't mean that there are "worse" or "better" versions, i.e. that a C6833 would be "better" than a C6802 when it comes to quality etc. They are equal.

The difference is LTE/no LTE in this case. A C6802 or C6833 that is manufactured today has the same quality so there's no reason to be afraid of one or the other.
[Sony Xperia Z Ultra] UserDemos:
As discussed earlier in the thread, the C6833 will NOT get AT&T LTE, only the C6906.
[Sony Xperia Z Ultra] Spixe1:
Just to doubly confirm, in the original post the "international" version was mentioned a number of times. Is the C6802 the international version? I'm an American living in China, and they have one called the LX39H. As far as I can tell, it is the same as the C6802, but, well, how can I be 100%? I want to be able to put on custom ROMs, etc, just like the international version, which I assume is the C6802 (right?). Anyone able to find if theres a difference between C6802 and LX39H and/or International?
[Sony Xperia Z Ultra] golfinggino:
anyone know if the c6833 will get lte in Canada on Rogers ? i have the C6802 already but would be interested in getting the c6833 if lte works with rogers
[Sony Xperia Z Ultra] SUPERUSER:
After I left CM10.2 rom and went back to radioactive I can not activate LTE.. It is stuck on WCDMA preferred, can't change it it just jump back.

Tried to remove my APN and fill it in again..nada :( Help? ...i dunno if this is the right place or I should use the Q&A, anyways

edit: got it working in PA rom

C6833 with Verizon

Can anyone confirm that the C6833 will work on Verizon? I am in the Chicago, IL area.

Thank you
[Sony Xperia Z Ultra] Spectre51:
C6806 should be available from Sony on Sunday. Just picked up mine from my buddy and he confirmed that for me.

do u mean like a sony store in the US?
[Sony Xperia Z Ultra] Spectre51:
Yes sir.

[Sony Xperia Z Ultra] Purple_Clouded:
Just to clarify ANY misunderstandings of any of the versions released of the XZU..

Here it is:

C6806 - US VERSION - LTE on ALL networks AT LEAST IN AMERICA (if offered by carrier)

C6802 - INTERNATIONAL VERSION - NO LTE on ANY networks - HSPA+

C6833 (I own) - INTERNATIONAL VERSION - LTE on ALL NETWORKS (if offered by carriers) EXCEPT AT&T

PLEASE, and I repeat PLEASE double and triple check the bands on which phone you're going to get. You're already on this forum website and probably looking on others to see if the version you're planning to get will work on the network you want, so go the extra 10 feet and see if the bands on your phone match the bands on your carrier.

It would be a tragedy to see you get a C6802 when you're on T-Mobile's 4G LTE........

FEEL FREE TO ASK ANY QUESTIONS.
[Sony Xperia Z Ultra] dzeek:
I can't seem to locate information that is definitive about whether Verizon supports a band that will enable the C6833 or C6806 to work. Could you please point me to it?

Thank you
[Sony Xperia Z Ultra] SUPERUSER:
That would be the C6806 at band 13
[Sony Xperia Z Ultra] dzeek:
Thanks. Where is that documented?
[Sony Xperia Z Ultra] SUPERUSER:
Here

http://www-support-downloads.sonymobile.com/c6833/whitepaper_EN_c6802_c6806_c6833_c6843_xl39h_5.pdf

And here

LTE band: http://www.cdg.org/technology/product_pavilion/operator_detail_lte.asp?operatorid=52

I don't see the band 13 now when I check but It says it runs on 700MHz? ...Today I'm not fully awake :rolleyes:
[Sony Xperia Z Ultra] dzeek:
Yes. I don't see mention of band 13 in either the C6833 or C6806 whitepapers. Does that mean neither phone will work on Verizon LTE?
[Sony Xperia Z Ultra] poisonsushi319:
can anyone confirm if the 6806 model will be available to pickup at sony store on sunday? I called the one in new york and they didnt have a launch date for this phone.
[Sony Xperia Z Ultra] servantz:
I ordered a C6833 off the internet. As I understand it this model should work on Tmobile, which is my carrier. Is there anything apart from entering the APN information that I need to do to get this phone to work 100% with Tmobile? Someone in another thread who has a C6833 can't get MMS to work on Tmobile.
[Sony Xperia Z Ultra] plastikpyro:
I'm running C6833 on T-Mobile in Irvine California and MMS functions fine. Phone connects to both HSPA+ and LTE with no problems. In the settings under "Wireless & Network", tap on "Internet Settings" and it will automatically download the MMS settings. Then add the APN fast.tmobile.com for LTE
[Sony Xperia Z Ultra] servantz:
Good news! Thank you for taking the time to reply.
[Sony Xperia Z Ultra] UserDemos:
No. It will not work on Verizon (Band 13). The 700 band is divided into several blocks (Band 12, Band 13, and Band 17). Each is a different slice, therefore different bands. Verizon is also CDMA, so none of the models support that either.

Sony only develops for GSM carriers. The last CDMA device they made was the Xperia Play, IIRC.
[Sony Xperia Z Ultra] IAmBrock:
I hope I bought the right one to use t-mobiles 4g lte C6833. I really want lte seeing my phone does not support it only hpsa +.
[Sony Xperia Z Ultra] cailiting:
In China mainland, the official released version are XL39H which is an equivelant of C6802. However there are grey market units from Hong Kong which is LTE version (HK has LTE) C6833, when you buy it, making sure you are getting the LTE version C6833 from HongKong market(note that HK also sells C6802 version).

Hope this helps.
[Sony Xperia Z Ultra] Spixe1:
Thanks for the reply, though a bit late, having already bought it a week ago, I can confirm that the XL39H is 100% the C6802, there is nothing different at all, the phone itself does not even show XL39H in the software, firmware, or hardware info, basically "XL39H" is just a stamp on the box and has nothing to do with the unit itself, which is what my main concern was (thinking it could lead to ROM compatibility problems). In general, the XL39H label can just be completely ignored.
[Sony Xperia Z Ultra] Purple_Clouded:
For those of you who are wondering if the C6833 works on Tmobile and can connect to their LTE, trust me, it works. Now I'm not sure if you got a bad version of the phone, but so far it's been a flawless experience for me. ALL MMS and messaging services work, and the phone is on the latest .532 firmware. You will notice that the phone will switch from LTE to HSPA+ from time to time.. This is perfectly normal, I'm in Seattle, Washington and my LTE speeds are amazing. Now given that you've done your research to see if getting an LTE enabled phone will be worth the extra cash over a 3G version then you should be well off.

Last but not least, when trying to connect to the LTE network for Tmobil, it will sometimes fail and I'm not sure why, but there is no need to input any APN settings or such, I've never had to do that so just be patient and try to get to a better place to connect with bette reception. Thanks!

Feel free to ask any questions.

-Purple_Clouded
[Sony Xperia Z Ultra] IAmBrock:
Thank you!!! I can not wait to get my phone. Playing the waiting game is horrible.
[Sony Xperia Z Ultra] alias3800:
I actually want to add to this and ask a question too.

I'm on tmobile and have 4g LTE in my area. I, however, traded and got the 6802, knowing that it didn't have LTE. I figured the battery would be better and that the HSPA speeds here would be good. And lo and behold, they are. They're generally around 7-10 mbps and get the job done for streaming YouTube and Spotify, etc.

So if you do get the 6802 for tmobile, it isn't the end of the world - so long as you live in a metropolitan area that has decent HSPA speeds.

My question is: Does the battery on the 6833 drain that much more because of the LTE? Don't know if anyone would have the means of comparing, but just wondering. I'm considering buying one off of Negri, maybe in a different color and I might end up buying the 6833. Kinda waiting for the Nexus announcement before I make up my mind though lol
[Sony Xperia Z Ultra] Buddy Revell:
So the C6806 won't be able to utlize Verizon's LTE network for data like the Nexus 7 does?

C6802 on at&t

hi guys, is anyone using the C6802 on at&t? if so, can you please post the network speed?

i have a note 3 and someone is asking to trade with the C6802 and i want to make sure that the speed is adequate enough for daily use

thanks in advance
[Sony Xperia Z Ultra] Purple_Clouded:
Most likely the Note 3 would be a bit faster. It all of course boils down to your location/your carrier's consistency/condition of the phone etc. But the C6802 wasn't meant to be on 4G speeds or anything above that. At best, you'll probably get HSPA+ which is what it was intended for. I'm not familiar with your area so be expecting somewhere in the 3G-HSPA+ speeds for the C6802.

I could always be wrong but that's what your best guess would be. Again, it's always good to check first and test it out, a simple app that tests your network speeds and such should do the trick. Ran multiple times, should give you a pretty accurate outlook on what speeds you'll be dealing with. Don't of course go test it in a place that you normally don't go to. (A mall that you NEVER shop at)

Hope this helped you out, I hop you make the best decision for yourself! Feel free to ask any questions, keep the thread going because many people have benefit from this!

-Purple_Clouded
[Sony Xperia Z Ultra] Purple_Clouded:
Hey, you're absolutely right! Like I said, always check and make sure you get what is RIGHT for you.

The battery life on the C6833 (T-Mobile) is actually not that bad. It can for SURE get through a day with good usage even though the LTE and NAV are on in the background 100% of the time. I have my brightness set on high as well, I usually get around 4-5 hours of screen time befor I have to plug itin and call it a day. Now I use a custom ROM (Carbon) and some custom kernels to kill some background apps and increase performance without biting too much of my batter life. But in the end, the battery of the C6833 (T-Mobile) holds up great. If you're thinking that the LTE would lessen the battery, especially if it's always trying to grab that signal when you're in an area that doesn't hold up with LTE very well, yes.. it does drain the battery more than your C6802. But ever so slightly you would feel the difference in your day to day usage.

In reality, if you're not an ultra gamer (see what I did there hehe) and is just someone who watches YouTube vids/checks email/FB/IG/TWITTER/ whatever you do, it should no doubt last you. But as I've stated before, I do run some custom kernels/ROMs so my records could be different than yours, but not that far off.

If you have the money and the guts to go buy one (Purple would be nice!!!) I suggest go ahead and get it! It's honestly an amazing phone that is very well overlooked at, easily trumping over any HTC, Motorola or LG/Nexus (Aside from the G2 of course hehe)

Let US know if you guys have any other concerns!!! Thanks ad hope this helped out!

C6833 vs C6806 in Asia and Europe

Is there any benefits or weaknesses for using the unlocked C6833 vs C6806 in Asia and Europe?

Thanks in advance
[Sony Xperia Z Ultra] PR0XIDIAN:
The C6833 is only 500$ on amazon instead of 7-8 hundred, and I use T-Mobile USA. So that's the one I'm gonna buy I guess.
[Sony Xperia Z Ultra] pwcchen:
I recently sold my Nexus 5 because t-zone or phone first web data plan is blocked from using data on the N5, my old nexus 4 works just fine.

I am thinking about getting the Z ultra c6833, does anyone have either the t-zone or phone first web data plan that can confirm it works? And are you able to get LTE working if so with which APN?
[Sony Xperia Z Ultra] PR0XIDIAN:
I actually work for T-Mobile as Tech support. :o Our regular APN is epc.tmobile.com our LTE apn is fast.t-mobile.com. The T-Zone data plan was never designed to work with smartphones at all. The fact that it worked with your nexus 4 is mind blowing. You will probably have to change plans at some point mate.
[Sony Xperia Z Ultra] John W Wheeler:
I have the c6833 in purple and the battery life is epic! I also rooted and ROMed this raskle. However it was awesome on the stock ROM too which only lasted about a week. I have a hard time staying away from CyanogenMod 's ROM

i currently have the c6802 version running carbon rom which i really like but looking for faster connection when i am on the road - i do have an lte mobile hotspot with me at all times that i can connect to which is certainly faster then the c6902 hspa+ connection but i am really thinking of getting the lte version, i am located in Canada and i thought i read somewhere that the lte version the sony store sells is the c6806 model and that the bootloader is not unlockable - i have been searching now and cant find anything online on this - does anyone know ? i picked up a samsung note 3 today due to the fast lte speeds but it is really just too small to use after using this phone, thanks
[Sony Xperia Z Ultra] Buddy Revell:
I know it won't work for voice because Verizon uses CDMA, but has anyone tried to see if C6806 works on Verizon's LTE network like the Nexus 7 does?
