Hi all,
I love to tinker and have been a regular on these forums since the early days of smartphones (long before android and ios)....suffice it to say I love to tinker with my tech.
Ok so here is the problem... After months of biding my time it looks like its time to get an HTC One.....and on research I've discovered my best option price wise was actually import it....and that the versions from Japan (Made in taiwan), China, and ?india? have Dual Sims, whereas those from HK, like those I could buy here in the shops in the UK take only one SIM.
Now it would seem a no-brainer that I should go for the dual sim option especially as I have two separate sims - one for work and one for play.
HOWEVER, I will want to root my phone immediately upon getting it and will DEFINATELY want to install custom firmwares in the near future.....
And so the question....never having owned a dual sim phone in the past.....Will these phones take the same firmware and then a little setting up with custom apps? Or will I need completely different custom firmwares? and if so is the CFW cooking scene as good for the dual sim version? (also I only read English and Spanish so I'm a little worried that I may not be able to read the pages where any dual sim firmwares might be posted).....
This would be a complete deal-breaker for me and I'd be forced to go with the single-sim option.
I've searched and cannot locate a clear answer to this question! All help much appreciated!!!
I have Dual Sim 802d version and its rock solid and all but the only problem I saw is non-availability of RUUs for the device (the Chinese ones caused radio problems for some fellow users with no signal and stuff) nor are their much custom roms for my device. After S-OFF I couldn't even flash Google Play Edition RUU as it bricked the device. Do a bit of research by browsing some of the threads. IMO if you aren't gonna customize your phone much like unlocking bootloaders, S-OFFing, etc.. HTC One Dual-Sim is a pristine device.
If you want more custom Rom and support don't go for dual sim
Smartphone and dual sim don't mix them battery sucker both ways
You will find your one SIM started problem in future not in network SIM not found like that
I have experienced with HTC desire v dual sim
from HTC One

If you do decide to go with the Dual SIM version getting custom ROM's might become a tricky situation.
Just for your reference for troubles that you may face see this: http://forum.xda-developers.com/showthread.php?t=2626054
If you want to use custom ROM's get the one SIM version, as for your dual SIM's the good thing is HTC One supports hot SIM swap so you can pop the SIM in and out with out having to switch the phone off
Good luck on your decision :good:
Single sim is the way to go!

Thanks for the advice all. Sadly then, as I had feared, my urge to tinker precludes my going for the dual SIM model!
A new cfw every 4 months or so is what stops me constantly wanting a new phone!

In that case...
You may also want to hold back on the purchase as HTC may rls a M8 Daul SIM version and I'm guessing if you buy the M7 at that time you're bound to get a better deal ?

Tempting - have been waiting for the price to drop ever since release and it just hasn't done it mind you! That said I can import it from as little as £200!!
whats the difference between the single sim and dual sim models?
do they receive the updates on the same day?
are there any potential custom rom issues with going for the dual sim?
I went with the dual sim as I really need that convenience.
When it comes to development, I'm sure it will be the same update schedule. Plus I see no reason why having a dual sim would hinder custom ROM support.
What's the reason that Samsung brings out 2 versions? Is it just a different SIM holder or are there more differences? I normally use 1 SIM. But might get another private one. And thus I also wonder if it will be needing different software when I decide to root it.
I have contacted Samsung. Their answer was that there is no hardware or ROM difference.
If this is correct. I expect double SIM bays to be sold soon by other suppliers.
Ordered the double SIM now. And will do the double SIM mod. As it only allows 2 SIM or 1 SIM + SD.
Since the second SIM slot can be used for microSD card, I don't understand why would anybody want the single SIM model... especially that it looks like the dual-SIM one is cheaper?! Here's an example of both models on the same site:
https://www.techmania.ch/Product/Detail/23991212?parnr=12833993 ==> single SIM = 1075 CHF
https://www.techmania.ch/Product/Detail/23309783?parnr=12833993 ==> dual SIM = 999 CHF
the problem that the brand version is single sim
DS have DUOS on the back I hate that part, but overall better for reselling and usage if you end up needing second SIM slot. I might move from 2 phones to 1 phone soon
The ROM is not entirely identical. In comparing the two I found that the dual SIM model has several libraries that are not present on the single SIM models, in addition to the obvious settings differences to let the phone know how many SIM cards to look for.
Dual SIM model here. But nothing mentioned on the rear.
I can think of at least two reasons they'd release a single SIM version:
1. Most network operators don't like users to have a second SIM from a different operator - it's easier for the user to switch operators
2. Companies have many reasons not to give their employees dual SIM phones. Also, they migh not agree with SD cards in their phones.
Just curious.
I wonder what Samsung does with the "extra" storage space that the second SIM would have occupied for a single SIM phone?
It can't be all about the SD card slot
Question: I've read that the dual sim is the "international" version, while the single sim is the official UK version, and that some manufacturers refuse to honour warranty claims for international versions of their phones that are often grey far east imports. Does this affect Samsung dual sim phones?
I know it's really early but i figured i'd put it out there.
Anybody know if the US Carrier's will allow and support Dual-Sim in their versions? I ask because i was hoping to use ATT's version to keep their Wifi Calling, HDVoice, etc as well as use Dual-Sim so i don't have to carry two phones around for work and personal.
I’m curious too.

No dual sim for US peeps. I hate it and do not understand why we can't have it.

Are you saying even the carrier unlocked us one won't have dual-sim... Damn
The color release is marketing and demand...they want to control the initial release. Sectioning colors to regions makes it easier to release...shortly after the high-demand release, we will probably see the other colors introduced. They have done this before with other devices. Sucks for those wanting to take advantage of pre-order deals. I wanted the deep blue but since it's going in a case, I got black and bought blue cases.
They don't sell dual in the US due to carrier pressure. Although slightly less so than a few years ago the vast majority of US phone sales are through carriers giving them the power to dictate product to some extent.
The U.S. Samsung web site is allowing pre-order of an unlocked variant; SM-N950UZVAXAA. The Best Buy web site shows this as a Snapdragon, dual-sim:
https://www.bestbuy.com/site/samsun...D=1&siteID=je6NUbpObpQ-05QPqugkIIKu.GTfe_wiOQ
I have asked Samsung support for verification as I need unlocked, dual sim.

A chat with Samsung online states no dual Sim for US unlocked phones.
Info: Thank you for choosing to chat with us. An agent will be with you shortly.
Info: You are now chatting with Srilatha R.
Srilatha R: Hi, thank you for reaching out to Samsung Technical Support. How may I assist you?
You: Hi, I'm interested in purchasing your Note 8. I am considering the unlocked version as I have lines with Sprint and Verizon. Will the US version of the unlocked phone offer dual SIM capability so that I can use one device for both carriers?
Srilatha R: No, US version phones are compatible with single sim feature
You: That's a shame but thank you for confirming. Is there any way to get a version that offers the dual sim capability?
Srilatha R: No, Due to product design of the phone all the US version samsung phones are compatible with only single sim
You: Got it. Thank you.
Srilatha R: But you can try with international version phones
You: How would I purchase an international version?
Srilatha R: You can purchase it from third party websites such as amazon
You: Ok, that makes sense. I owned the Note 7 and am eligible for the trade-in credit. How would I purchase through Amazon and then still get the credit?
Srilatha R: Well, if you choose to trade in then , that can only be done by Samsung.
Srilatha R: As trade in offer is not eligible for other stores or websites
You: Ok, thank you for your help today
Why you want dual sim peopole.
Its hybrid which means your 200 gb sd card will not work with the second sim card. That is coming from a dual sim samsung user..
That's good to know. I didn't understand that to be the case - probably due to the desire to have one device that would support lines from two different carriers. That's a shame though - many of us have personal devices and work devices that would, in an ideal world, be combined into a single device with the majority of needs met.

For average business user who do not need more than 64 gb of storage. The dual sim version will be a good choice.
Its hybrid sim thought meaning you chose either second sim or a an up to 256 gb sd card. You cannot use the 2nd sim with the sd card at same time.
You will have to order it from Amazon thought.
As a traveling person between 2 countries the dual sim is an advantage for me.

TL;DR - SM-N950UZKAXAA IS NOT DUAL SIM
Samsung Direct/USA or whatever you call it or whoever is being represented in Samsung.com/US has a listing during pre-ordering that the unlocked note 8 is dual sim. I even have a screenshot of that one.
However, same SKU - SM-N950UZKAXAA, is being sold in Best Buy. I did check both unlocked units in Black and Orchid Gray and as the store people have shown me, they aren't dual sim at all. Perhaps it was good riddance that the units are delayed in the shipping because I would be most likely returning that one eventually because there was some sort of deception on the item being sold. Now cancelled, perhaps I'll just get my Note 8 in few months time when the price is lower.
Hello,
I am willing to get the new Xperia 1 II. I am living abroad, and for many reasons, I kept my native country's sim to keep my line open. Currently, I own two phones to have both lines up. But this new Xperia seams to be released with a variant getting dual sim feature which is what I am looking for so I could replace my LG V20 and LG G8 for this amazing phone.
I read online that this phone comes with different variants:
XQ-AT51
XQ-AT52
XQ-AT72
SO-51A (NTT DoCoMo)
SOG01 (AU/Okinawa Cellular)
On this website https://www.xperiablog.net/2020/04/...eria-model-number-structure-for-2020-devices/ they tend to say that this XQ-AT52 model would be the dual sim variant, but I cannot find any online resources to confirm this.
Is there anybody who knows yet what is the dual sim variant so I don't get wrong while ordering?
(I really hope it's not only the korean version to get this dual sim variant...)
Thanks!
Hello,
I come back to you guys to have some updates about this topic since now they released the phone and preorders are available, maybe someone has some details about this feature.
I really want to know if the variant sold in Europe is supporting 2 sim.
On GSMArena, they list the phone as Hybrid Dual SIM (Nano-SIM, dual stand-by) but on sony.de, sony.fr, sony.it they list it as SIM NUMBER
Single SIM.
On B&H bhphotovideo, the phone is proposed as Sony Xperia 1 II Dual-SIM 256GB Smartphone (Unlocked).
Why would they sell a dual sim capable in America and a single sim in Europe?

The model selling in Taiwan is XQ-AT52 with dual sim ( 5G/4G compatible ).
If you put 2 sims, it runs in 4G mode, 5G is only working when only one sim card inserted.
5G I only works with 1 SIM card inserted? That's not very good design.
Also, can you please try to switch between SIM card for data, does it require a reboot to active? I used to own Sony phones and they all require reboot when switching between SIMs, which is very inconvenience.
I use other brand dual SIM phone now and they don't require reboot when switching between SIM.

Do you know if the only difference between the single sim and duel sim variations are the sim tray provided with the phone and the software installed. I am wondering if I got a single sim version, if I could flash the international firmware and replace the tray with a dual sim version

Normally it should work as previously it was like that.
but the SIM holder looks different to Xperia 1 dual Version
You don't need to reboot to change or swap sim, that's what i heard and that's why you don't need a pin to open the tray.. you just need to pull it.
I guess the tray for single sim is different but software is different too.. means software can handle dual sim..
I know some people with Samsung single sim model, they put 1 sim in tray and stick the second sim on the microsd. It becomes a dual sim with micro sd.
But you have to be very good to unstick the sim from original card and stick on the microsd without damaging your sim
HI all
has anyone found a way to keep both the Sims running even when the 1st has 5G on.. Like let the 2nd sim run at 4G or 3G atleast.. but why does the 2nd sim has to be off or go off when the first one runs at 5G.
I keep wanting to use 5G at all times on my first sim.. but why should my 2nd SIM stay off. this is mind boggling why would SONY implement this on a Premium Flagship while others Like Xiaomi and others have better sim management options even when 5G
this is the only thing stopping me from getting this phone although i love it.
on a separate note.
Also someone has any idea if the Special Frosted edition of this phone releasing in Japan with 12GB RAM will be dual or single sim ?
Is there a Dual SIM Snapdragon S21 Ultra model? If yes, what’s the model number?
The specs at GSMArena say:
Single SIM (Nano-SIM and/or eSIM) or Dual SIM (Nano-SIM and/or eSIM, dual stand-by)
So it looks like at least one of the models is dual sim (and it's mentioned in the description on the Samsung website) - but there's no indication which model it might be.
Samsung support said my unlocked 512gb will be dual sim - but it took a lot of time on the phone researching and calling other people for them to find that info. Not even sure if it’s true at this point. It’s very strange how this is so difficult to figure out
HK unit should have dual sim according to my supplier.

Why not? No carrier bloatware, dual sim's, unlocked bootloader, fast updates and the only call features you won't have are CA and 5G which at this time is more of a promotional gimmick than a useful feature.

What about the US unlocked version? I don't care about unlocked bootloader, I know how to remove/disable all bloatware. And, the speed of updates don't matter as much as they used to. This isn't 2012.
In India we have the dual sim exynos variant (Sim1 - PHY, Sim2 - PHY or esim) if you put in a physical Sim in the 2nd Sim position then esim gets disabled. If you use esim then the 2nd Sim is disabled.

Nope. I mean, I wasn't aware that it doesn't support dual physical SIM. But right on their website on the S21U page, it says that no US versions support eSIM. So I'm gonna go ahead and say that the answer is, unfortunately, no =/
But the good thing is that (probably with any unlocked version of the phone) you can just carry around both of your SIM cards and the sim pin tool in a really small, durable canister... You'd just have to turn off the phone and then swap the SIM cards whenever you wanted to change your service. It'd be slightly more annoying, but still doable!

from what I can gather, after a LOT of trying . . . there is no dual sim US version samsung phone. This from a lot of searching and phone conversations with several tech and sales personnel on the phone with Samsung. For this reason, I bought a non US version which broke the Samsung Health Monitor app and does not work for 5G within the USA. other than that it seems to be behaving nicely on the Tmobile US based network.

Ive tried that solution and its a lot more problematic than it might seem. I need the extra sim because I travel overseas and my US carrier starts complaining when my roaming data goes large (even tho they advertise "unlimited"). that means i would need to remember to turn off mobile data everytime i change the card. also the tool gets lost and bent and you can actually bend or break those sim trays after a lot of changing . . . not to mention losing sim cards on a bumpy train or taxi. I hate to invoke Murphy, but you can be assured that when a super important call is trying to come in it will not be on the line associated with the sim card currently installed. Sim swapping can also cause minor problems with messaging apps like whatsapp and telegram that could be a whole new thread. The only real viable solution for a frequent traveler is a dual sim phone with sim 2 used for mobile data in the locale physically present in. Second to that is carrying two phones. Least desireable (at least for me) is frequent sim swapping. That's my experience and humble opinion after years of very heavy international travel.
SM-G9980 has dual SIM fully working. I know for a fact because that's the version I have. }
I'm from Chile and the phone does everything I want it to do.
I have the 9980. It is fully dual sim but does not do 5G in the US. Occasionally I don't get data in some places in the US even when I have 5 bars. I'm guessing there are other bands this device misses. But that's rare. Everything is a compromise in life!
One good piece of news is that the T-MOBILE NOTE20 ULTRA now has it's esim activated. So if you are predominantly in the US this is the combo you need as it's dual sim and 5G in the US. The hope is that they do this with more devices including the s21.
