Correct, nobody has figured out a way to do it yet. It's possible we never will depending on if the X55 modem will ever play nicely. Nobody has been able to manage to boot the International 7T Pro ROM either, which could be a first step.

I have found people using dual SIMs on the OnePlus 7T. I think you just have to get SIM unlocked from T-Mobile then buy a dual SIM card tray.

Sadly, it's more involved than that. It normally involves switching to the international variant of OxygenOS. The problem: this device is a T-Mobile exclusive, which means there's no variant of the software that'll allow dual SIM without a custom ROM.

F/FD, Actual hardware differences between dual sim and standard?

Hey everyone.
Since Samsung's decision to unify all the devices sold to vendors into one unique device spread to all providers in the USA (the Snapdragon version) isn't it possible they did the same with the Exynos version and just changed the tray for the dual sim models, the hardware being in fact the same for both? (dual modem, dual sim reader, etc)
It would be nice if someone tried to fit a dual sim tray into a single sim S7/S7E. I've heard there are some S7e phones in the wild that do not have the DUOS name written on the back but are in fact the FD model.
Thoughts?
I'm in middleeast and yesterday i went to samsung store to buy one and store guy offered me the s7 edge 935f but as he said i can use either with two sims or one sim with memory I'm confused so i didn't buy it
Im not sure its the snapdragon or exynos
I think they only sell the Exynos outside of the USA

It would be very interesting.
dual sim tray into a single sim S7/S7E
I have the s7 edge single sim G935F but want the dual sim capability and wondered about whether it was just the tray, so i purchased a dual sim tray using just the one sim, i thought if i put it in the second slim slot it would still register but it didnt, so now i am considering trying to install the G935FD dual sim firmware. i have found threads where folks have done it the other way around, dont understand why but cant seem to find anyone that has tried changing from single to dual.
It will not work...
The G935FD has two IMEIs, one for each SIM slot. Even if you got a G935F to recognize both SIMs, the second SIM slot wouldn't have an IMEI, and you wouldn't be able to register it. There's no difference in G935F firmware and G935FD firmware at all. Its a matter of low level software and processes that recognize the SIM and assign the IMEI.

Is Dual Sim an option at all on the S7 Edge from AT&T? SM-G935A

HI!

Thank you,

I dont think dual sims are normally sold in the US. I purchased my from hongkong. Although i live in the UK i do like to use dual sims. However samsung s7 has one big problem. You can either use 2 sims or 1 sim and 1 sd card combination.

Yes I know dual sims is not big in US. This unit will be sent to my family in India hence the dual sim question. There is a hack to use 2 Sims plus microSD card but that's for later. Right now I want to know if there is a way to use two sims on my phone's model.
Thanks!

Single/Dual SIM versions?

I've read that the phone will come in two versions, one without the second SIM card slot (but still the uSD). Is there a way to know which version will ship in Europe? You can see the versions number on the official website: http://consumer.huawei.com/en/support/mobile-phones/huaweip10plus-en-sup.htm
VKY-L09 is single SIM
VKY-L29 is dual SIM
I don't get why they would remove this functionality for some parts of the world.
A lot of companies are backwards having this hybrid slot, giving you the choice of one (dual SIM) or the other (single SIM + expandable storage), although they are stuck in the 2013 bubble...some companies have actually moved on from there, but I'm surprised why this has not developed with major phone manufacturers.
RoOSTA
There is also the VKY-al00
VKY-AL00
Main SIM card:; LTE FDD: Bands 1/2/3/4/5/7/8/9/12/17/18/19/20; TD-LTE: Bands 38/39/40/41 (100M); UMTS (WCDMA) / HSPA+ / DC-HSDPA: Bands 1/2/4/5/6/8/19; TD-SCDMA: Bands 34/39; CDMA: BC0 (800 MHz), Only for China Telecom (China Mainland + Macao, China); GSM / EDGE: 850/900/1800/1900 MHz; ;
Secondary SIM card:; UMTS (WCDMA): Bands 1/2/4/5/6/8/19; CDMA: BC0 (800 MHz), Only for China Telecom (China Mainland + Macao, China); GSM: 850/900/1800/1900 MHz; ;

I received my pre-order yesterday, it's the VKY-L09 single SIM variant in the Netherlands, so I suppose the same is true for the rest of Europe.
I was speaking with a Huawei 'expert' at Carphone Warehouse yesterday, and asked about the dual/single situation in the UK. He said he has been told by an insider that a ROM flash wil be made available to enable the dual sim mode in single sim phones. He said the actual board and connector inside the phone are already in place, it's just the ROM that disables it and the sim tray that are different. He said his source said the ROM will be available in a month or two and the SIM trays will start popping up on eBay.....
Sounds like either the biggest marketing play ever to sell phones and hope no one really cares it doesn't happen, or Huawei realise the issue, and despite the UK networks not wanting it when they provde the phone to us, Huawei realise the potential of offereing a dual SIM option. I have to say he did not give me the hard sell at all, he said they only have a black phone in stock (and only one) and if I wanted white/gold (which I do) to wait a few days and try again. He had a P10 of his own, and was gushing about the P10 Plus like a schoolboy geek!
So there is hope yet!
Just been speaking to a senior manager at Huawei UK who picked up on this when I asked their Twitter account when the update would be available...
IT IS NOT TRUE the actual hardware is different with the single SIM version only having a single aerial so there's no way it can be flashed to make it duel SIM
WHy h why do sales people feel the need to say things that are not true!
Anyway my (probably single SIM) P10 Plus should be arriving today .....

Hi this is the reason I came here, the SIM tray for my VKY-L09 capable to put two SIM card, just the software not support. So maybe if Flash the dual SIM ROM can use as VKY-L29.

My SIM tray is capable to accept two SIM card with no user modification, that is why I though is only the software is different, but I already got answer here as the two model has two different hardware capabilites.

What I'm saying is people at any company will tell you anything to stop tampering with it both software and hardware. I have a dual SIM firmware on my l09 edition. If i can get a dual SIM tray or nodded tray I'll give it a go. Until both phones have been disassembled and had a look then all we can do is hope and try

its possible, Chimeratool .com does that, once you have the hardware hint in form of the second sim slot on most Huawei. Its the first hint possible conversion.

So that means Huawei lied to me? I guess possible..... not wanting single SIM to be easily changed to dual SIM.
So ALL we need is the SIM tray? The hardware definitely inside?
Wonder which country have the L29. UK only L09, I am thinking dual sim L29 as it will come in handy to have 2 sim if needed.

Hi all,
I've get my P10 Plus in UK couple of days ago. I was really disappointed that model doesn't support dual sim. Huawei Support also told me that my phone is single SIM only plus SD Card. But when I took a torch and flash inside SIM card slot I can easily see second set of sim card pins right upon empty space in tray. So I think it's highly possible to change ROM only and get Dual Sim Version. We need to wait couple weeks to release files for both devices and than check that
If you rebrand to a dual sim model, you can use both sims. Many people reported success already. Google for rebrand huawei p10 plus -- most success has been reported if you rebrand to VKY-L29C636 version.
Confirmed, i rebranded and flashed the VKY-L29C636 on my single sim and it worked, the only thing that i lost is the theme function. Somebody say how can i fix it?

One plus 8 pro dual sim solution?

Hello, just received my new 8pro but it is still not supporting dual sim. It's already September and I think it's ridiculous. Customer service is saying the same crap that it will be available it the next update.
Did anyone found solutions to fix the problem? Is there some kind of rom you can install to enable it?
Also Galaxy note 20 ultra is available in dual sim supposedly. The ATT version is locked as well. I don't understand why. I would go for ATT because they give up to $1000 off for trade in but again I really need that dual sim capability. It seems to me that both phones can be rooted and the issue will be fixed? Can anyone confirm that?
Any help will be appreciated.
It can be done with box and software modification, as all 8 Pro's share same hardware and modem/sim slot.
If you don't have any tool for unlocking/repair - just bring to local mobile phone repair shop.

the Android 11 dp4 allows for dual sim in the US.
Agree, 11DP4 is a good route to go...
Yup, I have one VZW SIM1 and my work TMO SIM2 and works great in DP4.

I had no issues taking the Sim out of my pixel 2 when I went to the Oneplus 7 pro. Then from the 7 pro to the 8 pro I had no issues either. Used the same SIM.
Open Beta has also recently came out today and isn't filled with bugs so I would recommend going that route.
Yes, Beta 1 should be a better route..
DP4 was pretty stable. I just installed Beta 1. Its only been a couple of hours but it seems to be pretty good.

Is it possible to convert T-mobile Single-Sim HD 1925 to Dual Sim ?

hi
Is it possible to convert T-mobile Single-Sim HD 1925 to Dual Sim ?
I would like to use say AT&T sim in slot 2 and Tmo sim in slot 1
I have no affinity for OxygenOS, any ROM should be fine... even Omni+microG is fine...
(just trying to understand the limits)
G
This has been discussed before, please search for details.
Nobody knows for sure that it's impossible, but there are no reports of it working with dual SIMs, and this phone is close to a year old now. The hardware on the 1925 is different (because of the 5G radio chip) so that Roms for other 7T variation models do not work at all.
Also the developer community is small. I would be personally surprised if it ever happened.
