Can some international versions work fully on AT&T? - HTC U Ultra Questions & Answers

I keep on seeing more and more eBay sellers and also on swappa, dual sim phones that supports AT&T.
Could that be?

Warning. Amazon international version does not have us lte. Seller misquoted bands.

So recently I bought the HTC U ultra International version from amazon(https://www.amazon.com/dp/B06X928N4G/ ). No Go. Its DOES NOT HAVE THE US or CANADIAN LTE BANDS 2, 4, 12 and 17. So anyone trying it buy it D O NOT buy it if you want to use it in the USA. Also the seller has misquoted the bands on the website. It is ALSO DUAL SIM.
The only one on Amazon that has the US LTE bands is the following. It is the SINGLE SIM MODEL. (https://www.amazon.com/dp/B01N35POJA). I asked the seller and IT WILL WORK. So anyone buying be careful and learn from my experience.
They also charged me a 20% restocking fee for the international version saying i did not verify the correct bands before buying. If your stated LTE bands are incorrect to begin with, how can you even make that argument? Guess ive my work cut out contesting that restock fee.

Inform amazon let them deal with it, very straight forward. Misinformation is not your fault, the cheek.
I've never had an issue getting a refund thru amazon uk.

Hope you get it sorted out.
I wonder if its truly a single sim model for the US market? I've got a Taiwanese model, and it is dual sim, but the second sim slot is a combo slot with microSD. since the "single" sim model also supports microsd, I wonder if the same components are actually there. would be interesting to see.
Hey OP. Not sure if you've sorted out the issue yet? I've got intl. version, with model as U-1u. Do you (or anyone else) know what the Single SIM version model number/name is?

Best place to buy Exynos version in US

Like the title says, what's the best place to buy unlocked international phones in US.
I also might have an option to buy while traveling to UK and looking for suggestions.
Will be using it on AT&T.
thanks!
The US has Snapdragon, the UK has Exynos

thanks for the eye opener, now back to my question "Best place to buy Exynos version in US"
In the past, I've had the best success with well rated ebay resellers. Having ebay back your purchase is important because they are so buyer centric. If there are any issues at all, they will force paypal to refund your money. The only downside to this, is that you'll likely pay a little more - especially if you purchase right at release time.
Wonda Mobile and Expansys are also great/reputable online resellers that will surely sell the S8 and S8+. You'll pay closer to the retail price of the device (no ebay fees, price gouging, etc) and their return policies are good. That said, YOU will pay return fees back to Korea if there are issues and you're 100% at their discretion for returns/replacements/restocking fees, etc.
Hope this helps.

I got my Galaxy S7 Edge (G935F) on Amazon and was going to get the NOTE 7 EXYNOS from https://www.bhphotovideo.com/
They are a good retailer - I am hoping we can get preorder from them - (they did offer a preorder for the NOTE but it never happened because batteries started exploding before the NOTE 7 Was released.
Silly question - but why would one prefer the Exynos version over the Snapdragon? Is there a noticeable difference in performance, or some other factor?
From what I hear, the performance on the Exynos variant is better than the Snapdragon variant. Also, the SnapDragon variant has been bootloader locked as of lately (Note 7, S7, and S7 Edge) while the Exynos variants have been unlocked.
So I pre-ordered a sim unlocked s8+ through samsung's UK site. not sure if they will ship to US though
Greetings from Canada,
Would anyone know which "soc" goes in the Canadian variant?
Thank you.

thats so naive from you..see the galaxy s7 exynos variant was unlock the past year where the s7 820 was not, what that means ?
basically means that you was not able to root any western device , but only exynos variant can... and root a device is crucial to open a lot of possibilitys like overclock
and responding to the question of this guy, basically in every latin country on america you can find the exynos variant, which is kind a weird cosidering that allways all america used the qualcomm variant in the past , and because a lot of mexicans carriers dont have the culture of wait until the oficial release of the smartphone i will expect some people to buyit long before

Canada is getting the snapdragon like the USA unfortunately.
Handtech and Clove are both reputable UK shops that many on this forum have used and recommend. Be aware if you're​ a first time buyer at either you may have to jump extra hoops to clear your credit card. This is normal and due to the high degree of fraud in international cell phone sales​.

BH has it listed now, but just to notify when available. It has it listed as SM-G955. It doesn't say whether or not it is SD or exynos though.

I know with the international S7, Samsung Pay would not work in the US. Not too worried about that, but are there any other drawbacks? Will it work on all the LTE bands for AT&T?
I think for those that really want the international version, you'll have to find overseas sites that ship to the US or get them from a reputable seller on eBay such as never-msrp. The downside, as always, to importing is a higher price and generally, no warranty. I generally get quarterly trade where if anything happens and no one fixes the phone, they'll just give a full refund of the phone price. Anyways, just make sure it says SM 950F or SM 955F. The F are the true international unlocked models. Samsung pay may now work in the US. Check out the S7 threads to see how they got pay to work in the US

The s7 had all AT&T and tmobile bands. Volte didn't work and wifi calling also didn't work on tmobile tho even though the s7 had band 12. It just would not connect. I now have att so that's no longer a concern with me

I contacted the UK samsung web page and the sim free version still need to make a 5 minut call in the uk first to be truly unlocked, as it has region locked.
Check out clove UK. They have the cheapest pricing for the S8 and the s8+ and you get the international model. Picking mine up Soon

You don't want them to ship it. The EU phones have region lock. To use a SIM from a country different from the phone's selling country you have to make a 5 minute call on a SIM native to the selling country on a network native to the selling country. That's why all the grey market phones on eBay are mostly from Asia.
Here's an article on it.

LTE on ATT works fine on the International Varients - the only thing missing is WIFI Calling and VOLTE - if those are big deals for you, yoiu need to stick with an ATT Phone. I haven't missed them - LTE speeds for me have always been great - I don't need WIFI Calling - and HD VOICE, well, I am not so sure it is everythign it is cracked up to be - call quality for me has been very good - so I personally am not missing anything.
I have wondered for a while if the snapdragon model in the US isn't something paid for by the NSA to be a the only US variant offered. Like more backdoors, etc built in to the Snapdragon variant. Unless there is some other obvious reason why the US gets only the Snapdragon variant.
It really doesn't matter for daily usable or noticeable performance however. Bet you'd never be able to tell which variant you were using if they were set up the same and you didn't check in the settings to cheat to see which variant it was.

"CN version" Available on ebay. Will it work in the US?

As stated the P10 plus is available on ebay, I am just wondering if I should wait or if the CN version would work on US cellular carriers? thanks!

You should look at the LTE Bands supported, compare it to the ones used by your US provider and make up your own opinion, no?
Actually no, because over the years of buying unlocked phones I have found that ebay listings tend to lack these facts or are not trustworthy, especially when they are written overseas. I will not drop >$800 on a phone until I know for sure. I posted here since I figured some may already have experience with the handset. Thank you
Then you should wait. If ebay listings are the only source you can find for technical information on the p10 plus then don't risk your money.
Even if bands work you could end up with a Chinese model like what I got when I ordered a P9 Plus and didn't pay attention to model numbers. It wasn't a big deal, just took some time to get Google play installed. And some apps and settings not in English
I have a mate 9 china version and it works in Canada on Telus and Rogers network. Just FYI.
A spec list from huawei Chinese website for P10 Plus:
LTE FDD:Band1/2/3/4/5/7/8/9/12/17/18/19/20/26
TD-LTE: Band38/39/40/41(100M)
UMTS(WCDMA)/HSPA+/DC-HSDPA:Band1/2/4/5/6/8/19
TD-SCDMA:Band34/39 (移动主频段)
CDMA(主副卡二选一):BC0( 800MHz);(仅限中国电信(中国大陆+澳门))
GSM/EDGE:850/900/1800/1900MHz

Awesome, I was crossing my fingers since I'm on T-Mobile as well.
Edit: Got my phone and went over to the T-Mobile store. Full coverage as soon as they put the nano sim in!

Oneplus variant (single/duam sim) from oneplus.com shipping in the states

Hi
I wonder whether or not the variant sold by oneplus.com website, when buying and sending the device in united states, will be single sim as in TMobile, or the regular, world wide variant with dual sim support as sold everywhere else?

The T-Mobile version is locked to T-Mobile so you can't use a second SIM.
I saw some pictures and it looks like the SIM doesn't have the second slot.
For the version listed at OnePLus, it has dual SIM support.

So far it's just the tray that doesn't have a second slot. Nobody has yet confirmed whether there is a second slot in the phone itself.

If you buy on OnePlus sure you'll have the regular phone. Only tmo sells the modified one
The tmo one has a tray with only one SIM case, and a modified firmware/modem. If you read the (too) many threads speaking of tmo you'll see the endlessly same questions and remarks about that.
Never buy a phone through a phone operator.
