Engadget "When we reviewed the Sony Xperia Z Ultra, it was with the C6802, a HSPA+ model devoid of LTE bands. However, it seems that a speedy 4G version of the handset will arrive stateside soon, if this recent FCC listing is any indication. The document shows what is clearly the Sony Xperia Z Ultra, but with AT&T-compatible HSPA+ and LTE on board. This means it's likely the C6806, the handset's North American cousin, all set up to take advantage of Ma Bell's super-fast network. It doesn't look like there's too much else differentiating it from the international model however, so we'd take a gander at the review one more time to decide if it belongs on our wish list."
It would be very unfortunate with a branded Ultra since it would mean a crippled device with a crippled radio.
The C6806 standard edition offers both AT&T, T-Mobile and European bands (some slight differences there though, the 6806 has the 700 and the 6833 the 800 band).
So an unlocked C6806 is great but if Sony let a carrier fiddle with it, I guess that a couple of LTE bands will be removed (see what T-Mobile did with the Xperia Z C6606).
The best solution would be that Sony sells the Ultra unlocked through Sony Store - the C6806 that is. AT&T et al branding, bloatware and locked bootloader would destroy a magnificent device.
coming from a LTE ATT device to this, i can tell you, I DO NOT EVEN MISS LTE. for music,youtube,web,email,fb,cloud storage i do not see any difference
I was originally on the galaxy S3 with LTE, and switched over to a note 2 unlocked non LTE and sure, my speedtest scores aren't as high, and my downloads aren't as fast, but unless you're visiting some super graphic heavy site, it's not a huge diff. Plus LTE drains battery faster I believe. On a battery draining device such as the Ultra, you definitely won't want LTE constantly draining the battery. Especially if you're not on unlimited data.
I wish the C6806 was sold unlocked, but that's probably the Tmo version - which means they'll lock out a certain LTE band (700)

You know, Negri Electronics has the C6806 up for pre-order.

For what it's worth, Negri also had the Xperia Z NAM edition (6606) up for pre-order, and that is nowhere to be found except on T-Mobile.
I hope I'm wrong, but with Sony signing an agreement w/ TMo, I don't expect LTE devices to be sold unlocked by them in the US anytime soon.
The positive side is that if the C6806 is destroyed by a carrier, the C6833 will work in the US since it has the T-Mobile bands and can use AT&T albeit without the 700 band.
So an option in a worst case scenario is to get the C6833 imported for those that demand LTE.
Unlike the Xperia Z, the C6806 and C6833 are pentaband like the C6802 and offers LTE in addition. The C6833 should therefore be an adequate option for US customers if the C6806 is messed up.
I am still hoping that Sony will sell the C6806 unlocked in the Sony Store but the C6833 is a perfectly adequate option.
Personally, the lack of VoLTE made me skip the LTE versions in favor of the C6802. Streaming videos etc isn't really an option on US capped plans and the HSPA+ speeds I got on the 6802 is very adequate for browsing, navigation, picture uploads etc.
I dunno, with the cost of C6833, I'd like the ability to use LTE with ATT.
It's kind of a no-win situation, since the C6833 will be available unlocked but without the 700 band, and the C6806 will be available but gimped.

Sony sold the Xperia ZL LTE unlocked on their website, they might do the same for this phone as well, at least i hope that's going to be the case.

How do you know that? I wasn't under the impression that any US carriers were likely to pick this device up.

It's rumored that Tmo might pick it up, since they have a exclusivity deal with Sony. Just speculation.
so currently the device will work fine on both ATT & Tmobile with HSPA+ right?
just no LTE

Correct - I have a Lumia 1020 and the Ultra Z C6802 on ATT. Here's some speedtests for you:
Ultra Z in HSPA (not even HSPA+) is getting 6Mb down, 2 Mb up
1020 in LTE gets 15Mb down, 11 Mb up
Despite the desparity, I don't notice that much difference in surfing. - not to mention the Z feels the fastest of any device used since the original Moto Xoom overclocked to 2GHz
Hope this helps!
I ran a SpeedTest yesterday and got a download of 8.3 Mbit/s on the AT&T network with HSPA+ and Straight Talk. A few minutes before, I ran another SpeedTest on the new Motorola Droid Razr Ultra and got... 3.5 Mbit/s - that's on Verizon 4G LTE.
So I am certainly very happy with the speeds I got on the Ultra in the center of Manhattan (the tests has been made near Grand Central).

Great deal for sure. Anybody ever done any business with them? If not I'd probably be more comfortable buying from Negri.

That's interesting... Looks like the C6833 is MUCH more compatible with North American frequencies than the C6603 was.
C6603 (Euro LTE Xperia Z) lacked UMTS1700 and UMTS1900 support, which meant no 3G at all on T-Mo and 3G only where AT&T had UMTS850 service.

Sony took the decision to use a top notch LTE radio in order to overcome the old limitations that plagued LTE devices until now. The only thing I don't like is the lack of VoLTE and it is one of the reasons why I went with the C6802 instead of following the original C6833 plan.
The only band missing on the C6833 is the 700 one, otherwise it should work nicely in the US meaning that it is a great option if it would end badly for the C6806 (i.e. carrier branding, removed bands and locked bootloader).
So guys I have the opportunity to get this beautiful phone, but I did not understand the difference between the two models at my disposal.
I can get a c6802 model for 510€ (689 US$) or a c6833 model for 619€ (837 US$).
What I cannot understand is: what is the difference between the two models?
Concerns only the bands (one have LTE and other not) or I could have problems in the future with things like updates or modding?
Thank you guys for your help!! :victory:

Xperia Z Ultra LTE C6806 (LTE; Bands I, II, III, IV, V, VII, VIII, XX)
Xperia Z Ultra LTE C6833 (LTE; Bands I, II, IIII, V, VII, VIII, XVII)
Xperia Z Ultra HSPA+ C6802
Other than modems there is no difference.
At the moment the LTE models can not run on the new firmware. (well it can but LTE connectivity doesn't work) Other than that they seem to be the same. The firmware will work on either unit...
It comes down to if you want faster download/ upload speeds with mobile data.
- For me the extra money spent on the c6833 model wasn't worth it. Work and home have wireless, and the limited time I'm out and about HSPA+ is fine.
Do a quick visit to gsmarena.com.
To the upper right hand corner, you will see a search box.. just search for the ultra there.. you will see that the differences just lie on their network operating frequency (at least that's all i see :what
Other than that, it is pretty much the same...
I admit, the price difference between the LTE and hspa+ version is not worth it.
But here at my place, our network provider is pretty much forgetting their HSPA network and just dont want to fix issues anymore.. they are more focused in upgrading and stabilizing their LTE infrastructure so I'm just going to go with the flow and buy the LTE version..

Any T-Mobile USA owner now there, can you please confirm that with an active T-Mobile SIM, can you do Wi-Fi calling on this Sony Z Ultra? If so, was the Z Ultra a Sony version, or GPE? Thanks!

Tmobile wifi calling working only with Tmobile certified phones., which is on sale in tmobile stores.
Xperia Z Ultra and Z Ultra GPE don't have that future.
If you have a choice buy Sony version of Z Ultra. Why ? There is many posts about it.

Well...
Here is the thing, I have a MetroPCS Alcatel OneTouch Firece, I unlocked it, put my T-Mobile SIM into it, and I was able to make Wi-Fi calls.
Obviously, this phone is not a T-Mobile certified phone, it does not have any T-Mobile software on it, and, when I am in-door with no cell signal, the phone shows MetroPCS, so what gives?

I am considering purchasing a Z2. I am on AT&T. Can anyone confirm that they have a Z2 working on AT&T? It seems possible with the bands it has, to fully work on AT&T.
D6503 working 100% on AT&T. Just took the Sim out of my old phone (already had a previous AT&T LTE device) and put it in the Z2. No issues.

Hello,
I wanted to ask you one
one thing my Sony z Ultra (6802) shows MSM8974 processor. as per Qualcomm website MSM8974 has built in support for 4G LTE.
So can I flash my phone with firmware of Sony z Ultra 6833. For enjoying 4G LTE. If yes do provide me with the links for stock Sony z Ultra 6833 firmware.

seems good,
but I need to change variant of the phone in order to support it... Well I'll try these when it's out of warranty.
The other way I have heard is to unlock bootloader then again lock it when done.
And yes it is tricky
I don't wanted to mess up with firmware it might brick my cell...
* Actually I am new to these things *

MSM8974 can support LTE but C6802 doesn't. It doesn't matter what ROM you flash to C6802. I would suggest selling that phone and get another Z Ultra variant if LTE is important to you.
