T Mobile is the exclusive US carrier for Sony Xperia. That includes all the different phones with Xperia in the name including the Ultra. If T Mobile does not sell it, it will be in the Sony store. The phone will work on ATT as well although the version currently on sale outside the USA will only work on the 3G network.

The c6806 is already available, and is the LTE version for north America.
Take a look here http://negrielectronics.com/sony-xperia-z-ultra-c6806-unlocked-black.html from what I read on internet while looking which I need in Europe. People was saying that the LTE bands on this model are those for North America. ATT use 700 and 1700 bands and T-Mobile use 1700 only. Both of those bands are on the C6806 version.

It looks like that website still says "Preorder" instead of order.. looks like its still not out yet.
Hey guys
If I remember correctly, if the phones is compatible with ATT it usually runs well on Canada LTE's right?
Thanks for any input regarding Canada better model to chose ( Rogers for example )

T mobile v 10.some questions

What is the difference between the t-mobile variant and the international one accepted that the T Mobile version doesn't come with headphones?
Do I get updates from LG or need to wait for t-mobile to release it also like with a galaxy s6 edge on AT&T? That btw I waited forever!!
There's going to be an international variant to the us unlocked or only carriers?
Tmobile version update is provided through tmobile. But this is xda, I am sure can run international update at some point.
Tmobile version currently got unlocked bootloader.
If you wait a few more there should be some international varient unlocked to work with tmobile, but you wont see them being sold in store....ebay maybe amazon is best bet.

Us Cellular version to use with Verizon

So I just read and saw on line that the US Cellular version of the LG G6 is on $550 buy it out right. Would this version work with Verizon Wireless. It looks to have the same LTE bands. What would be the chance of buying and putting a Verizon sim in it and it works out the gate. Anyone have any ideas?

GSMarena doesn't currently list 3G bands for the US Cellular G6 (US997). However, I've seen the Verizon and US Cellular versions of phones differ on 3G bands before (see the Galaxy S7 USA, for example), so 3G might have problems if you just popped a Verizon SIM card into a US Cellular G6.
I'm wondering if there could be a similar method to the one that was discovered for the HTC 10 where you flash radio images from the Verizon variant onto another phone:

Is the us cellular version factory unlocked? It is the same model number as the unlocked version, us997. I'm looking to use on AT&T.
It looks like you have to pick up some kind of plan from them to get the $550 price. It's probably better to go the b&h route (or hope vzw does a mother's day week sale).
Update: Ended up buying a new us cellular us997 for cheap. Popped my straight talk/at&t sim in and it works flawlessly. I always use this site to check bands
https://www.frequencycheck.com/compatibility/0Dlph6Y/lg-us997-g6-lte-a/united-states
I have used that site several times and its always been accurate. From what im seeing, the us cellular model supports all of the bands needed for verizon. It doesnt support CDMA2000 1xEV-DO Rel. 0 but does support CDMA2000 1xEV-DO Rev A. So if 3G is a major concern, I'd check and see which one is used in your area. I personally wouldn't care about the 3G considering the price difference of the USC model and the fact that all LTE and voice bands are supported. Hope this helps

Galaxy S7 & S7 Plus 5g Bands Help

I Purchased the note 20 Ultra 5G in USA and shipped it to Australia.
I later found out that the US Note 20 Ultra 5G variant doesnt have band n78, which is the main band of Asutralias best 5g provider, Telstra.
I am wondering if anyone knows conclusively if the s7 5g or s7+ 5g has the n78 band, some websites denote it does, others say it doesnt, but i feel they might be reffing to the LTE version sometime which of course does not have n78 5G band. This is the US variant from Samsung.com website.
Thanks in advance

Question European S23U in US

Now when European S23 Ultra is using Snapdragon - will it provide better 5G connection capabilities in US - especially on TMobile network? Or is it still locked to the same (limited) bands as Exynos S22?
thanks
It's SM-S918B or SM-S918B/DS right?
It would partially get 5G specifically for TMo where areas have n41 (2500)
Only the SM-S918U or U1 has the mmWave antennas
These are what T-Mobile uses for 5G
n260 mmWave (39GHz)
n258 (24 GHz)
n261 mmWave (28GHz)
n71 (600)
n41 (2500)
SM-S918B/DS.
Ok - so it looks like it will not be better in US than S22 Ultra Exynos.
