Using dual SIM tray on unlocked T-Mobile 7T

Anybody used Dual SIM Tray (bought on Amazon, eBay, AliExpress) on unlocked T-Mobile OnePlus 7T? I am planning to buy phone from eBay and wanted to check if using dual SIM tray is possible...

Not possible without flashing the international firmware which I don't think the tool is out yet to do so. If you want dual SIM I'd suggest but the international version and NOT T-Mobile variant. Hope this helps.

The post on how to convert to International Firmware has been up for over a month. I used it and am now on International Firmware. I don't have the dual tray yet but it has been ordered. And I am confident that dual SIM will work as I can already see mention of it in certain apps. Apps that made no mention of it before the conversion.

Could you share the link where you bought and your feedback is good?

Short answer: yes, doing this now. Just grabbed the cheapest one on amazon (was $6 but the seller has since sold out).
Unless the tmobile variant you're buying is already bootloader unlocked, it's critical that it's permanently sim-unlocked. That should generally also mean that the phone was fully paid off (although not the case if unlock was obtained from mobbdeep here). Do also know that it will take 7 days to get your bootloader unlock bin after submitting the request.
All in all, unless it's a terrific deal and you can be sure / chance it being fully paid off, not reported stolen, permanently sim-unlocked, and you're capable of flashing to global firmware, you're probably better off getting the regular hd1905 variant.

So far I have not been able to actually insert it into the phone. The tray looks like it should fit but I can't seem to work it in. I gave it about 20 seconds and then went off on a different project. I will look at it again this weekend.

You are correct. And I did use Mobbdeep for my SIM Unlock. And, of course, the Bootloader unlock for International Firmware install from O+.

Were you able to insert the tray into the phone?

Please clarify if you have just an unlockted TMo OP7T with a dual SIM tray OR if you have flashed the phone to an international ROM?
If it is the former, I assume you are able to use both SIMs. Can you do voice, text and data on both SIMs?
PS: Please share a link/name from where you purchased the dual SIM tray. Thanks.

That's what I read and thought/knew. I guess the framing of the comment threw me off.
For those who have migrated the TMo phone to the Global ROM, please share if voice, text and data is functional on both SIMs. I have read WiFi calling and other stuff works but was not sure of data. Would be also helpful to find out where you purchased the dual SIM tray....just so I can buy from the same seller and be assured of the fit.

i flashed the international rom and bought the dual sim tray off amazon everything worked fine calls texts data at least for me

I am using TMO 7T unlocked rooted converted to Int'l OOS, using dual SIM (Tmo and ATT). Talk Text works on both no issue. VoLTE works on both. VoWiFi works on TMo, not sure for ATT since its Work SIM.

For those of you who have flashed international firmware, have any of you been able to relock your bootloader after the fact to get rid of the boot warning and to make protected apps (Google Pay, etc) work? Seems like, using a OnePlus image, this should work...

Msmtoolkit is the best and safest way to lock your booloader. However with magiskhide the apps you mentioned should work. Unless they are checking the bootloader status

I know this thread is getting old but yes. I unlocked the bootloader on T-Mobile varient, flashed international firmware, did an immediate OTA update and then relocked the bootloader. All is great. Using a dual SIM tray now and both SIM slot work fine...no issues.

G9860 (HK or TAIWAN) for use in the UK... questions

Hi, apologies for starting a new thread on this. I've asked the questions but can't get a definitive answer so hoping this will help me and other prospective buyers.
I have 2 options. Buy from wondamobile and get the HK version (TGY csc) or buy from T-dimension and get the Taiwan version (BRI csc)
Both are dual sim 128gb. However I want to be able to use both an sd card and a 5g sim. I'm seeing reports that even after the latest firmware update, you can only get 5g if you put the sim in sim slot 2. Is that true because I wouldn't get it if I can't add an sd card as 128gb is nowhere enough space and I don't like saving my pics to the cloud and my WhatsApp media folder just grows and grows as I like to keep old stuff.
So really:
1) can I use both sim slot and sd card and still get 5g here in the UK (EE). I've checked and the 5g band n78 is what ee use so it will pick up the 5g signal
2) does it matter which version I get, hk or taiwan?
3) even though wondamobile say volte and WiFi calling won't work, I think with the latest update they do work. Is that right?
4) is t-dimension OK to buy from?
Thanks!

So I bought from t-dimensions via eBay (G9860). They are based in HK so u assumed I would get the HK version, however I got the BRI version. As people have said in other threads, there's no option to select 5g on this model as there is no 5g in Taiwan yet.
I changed the CSC from BRI to TGY using Sankey using a guide on this forum - was relatively simple process and didn't wipe my phone - I can now select 5g for both sim 1 and sim 2 - whether I can actually get 5g I don't know. While passing through a 5g area, I didn't catch a 5g reception, only 4g plus (I'm on a Vodafone 5g tariff) so I'm not entirely sure. My Vodafone SIM was in sim 2 tray.
Also both Google pay and Samsung pay work. For Samsung pay, when signing up you have some Chinese writing, but after that it's all English and you can add UK cards to your account. You will see a Chinese banner with HK ads thou.
WiFi calling works for me, volte doesn't appear to despite it being selected.
Not really answered your questions, but hopefully my experience is helpful

That helps a lot! How was your experience with t-dimension in terms of delivery. I heard they also ask for ID which I'm hesitant to send to China lol.
Interesting about the 5g too. I'll need another person to share their experience in relation to it working. I know I read one guy on here say it only works in sim 2, but they never mentioned if the option was also there for sim slot 1 and that they selected it but didn't pick up anything. 5g can be dodgy so who knows.
Samsung pay and Google pay I don't use anyway so fine with that not working. I think the same guy mentioned volte worked on ee... Again I dunno which sim slot or if it matters, or if you need a base hk model like his. Is there any reason why you have yours in sim 2 by default?

So they didn't ask me for any ID - the only issue I had was that I ordered the cosmic black version and they messaged via eBay that they don't have it in stock and would I like either grey or white instead. I asked how long for the black and was advised they don't know so if I want black they would rather refund than hold the order... I decided to go for white - actually glad as it looks quite nice and not had a white phone before. It took a week to arrive - they used DPD. No tracking available until in the UK which got me abit worried, but as soon as it showed up in Manchester, DPD delivered it the next day. Btw I didn't have any customs or tax charges either.
From what I read on trustpilot it's sounded like they only asked for ID if your delivery address was different to your PayPal verified address. Again, I ordered via ebay and PayPal so maybe that's why I didn't get asked for ID.
My primary number is in sim 1 and sim 2 had my simo which I use for data. No other particular reason for that order, that's just how I had it in my last phone (OnePlus 5t).
Only other thing to add is that if 5g is selected for sim 2 and then try and select it in sim 1 I get the message ' if you change sim 1 to 5g, sim 1 will be used for mobile data' and then sim 2 changes to 4g - so you can only have 5g selected for either sim 1 or sim 2, not both at the same time.

Why not buy from a reputable store like The Carphone Warehouse?
Then you get a warranty, and know it will work on 5G
NO way would I buy from some foreign website or ebay for something that expensive, ebay you will lose your money if it breaks, and quite possibly with those online sites too, the wondamobile one already says they are unsealed because they had to activate them before shipping, I wouldn't be accepting a £1k device that had already been used / possibly refurbished, possibly IMEI stolen / blocked
Spend the little extra and buy from the UK, and not ebay/amazon, buy it new from a good rep store

So the eBay trader ID they used is 'skytrade19' but had all the blurb of t-dimensions. Also I got emailed a t-dimensions invoice afterwards with 'skytrade19' listed as sales agent. The item id was 153876284501 - I can see it in my transaction history, but looks like the listing has ended.
T-dimensions does have a store on eBay.com.au - item id 392790145906 will bring up the listing for the g9860 in white. Converting the price from AUD to GBP works about about £660. I'd message them and ask if they are willing to list on eBay UK if your keen on buying from them on eBay.
I haven't bought like this before but wanted the Snapdragon model like you. I liked the idea of ebay and PayPal protection together so took the gamble and bought it. I used PayPal credit as well so should have section 75 protection for my purchase (which I wouldn't have if I used PayPal with a credit card) - see mse forum for details on the section 75 stuff.
Anyway it worked out for me overall, that's all I can say.

No they haven't, mine is the Exynos version and it is fine, this last update fixed the only issue I had with it and that was a delay taking selfie photos with the front facing cam, now it's instant
I've been talking to a guy who exchanged his Exynos S20U for the Snapdragon version and he says the only improvement is it doesn't get as hot during game-play, but videos and selfie photos are worse
Don't listen to the SD owners hating on the Exynos, and likewise vice versa, and if I was going to import a SD model from anywhere it would be the US, not Asia

The last update that was released for BRI with July patch has also activated 5G so there is no need to change csc to TGY if it was originally BRI.

Does US variant come with dual sim active?

My phone shipped from Amazon today and due Monday. Does anyone know if the US unlocked variant shipp with both sims (nano and eSiM) active? Need dual SIMs for work so hoping it does.

I checked Motorola's site earlier today, in the specs section, down in the fine print notes, it states Dual-Sim capabilities will be introduced at a later date & may vary depending on carrier model.
At the minimum, sounds like you may have to wait for a software update to enable Dual-Sim capabilities.

Ordered mine from Motorola yesterday and hoping it comes with dual standby. However, I checked out a T-Mobile version yesterday and although it allowed to hot-swap swap from Nano to eSIM in the software it only had one IMEI number... Hoping the unlocked version maybe different but no software update can alter the missing IMEI. Fingers crossed but honestly not hopeful.

Mine is on the UPS truck for delivery this afternoon (unlocked version bought on Amazon) - earlier than expected so I will be able to report back after I have it. I'd read the info on the motorola website mentioned above and was hoping to get a definitive answer.

I got my unlocked Razr 5G (from Amazon) today. Box only shows 1 IMEI. Pretty sweet device - just working on setup but I can report that 1) both eSIM and the Nano SIM work BUT (and this is a really big BUT), only one can be active at a time. I started with my AT&T nano SIM in the device and it works great. I then switched to the eSIM and added my UK eSIM plan to the phone.
I was then able to go back & forth between the SIMs using the switch SIM menu option and it worked fine but only one can be Active at a time so when AT&T is active, no calls, etc on UK eSIM and vice-versa.
So, while it is technically a dual SIM phone, it does not behave as you would expect (or prefer) for a true dual active-dual sim phone. Given the box only shows 1 IMEI i'm doubtful the phone will ever be dual standby (which would require 2 IMEI's) so I'm not sure if I'll be able to use this as a daily driver or not.
Mine is the US version - nXT2071-3 - hopefully someone in the UK or elsewhere with a different model/firmware can confirm if another version is true dual SIM.

But... i have dual Sim smartphone, and it uses 2 nano-sims. I have them both activated and so the phone shows the two IMEI (from both carrier sims). My previous non chinese smartphone was an iPhone 11 and it had esim and a sim slot. So I used the first e-sim with my Canadian carrier and the sim card slot with my other canadian carrier. I could use both phone numbers on the same device but if one phone number rang on the phone I could not receive an inbound call on the second number.
Is that not how the Razr 5G works?

US variant (XT2071-3) that I got does not work like an iphone 11 (which i what I have now and,like you have one carrier using nano sim and another using eSIM) and both can send/receive calls and text - though like you said not at once- and it can do that because it has 2 unique IMEI and which allows it to register on 2 different networks. Moto XT2071-3 only have 1 IMEI - can only have 1 number on at a time and when one is on, the other is off - doesn't receive calls/texts when off.
EU variant XT2071-4 is supposed to come with 2 IMEI to work like your iphone 11 - both sims can be on and get calls/text. Very few have been shipped. i have one on order and will confirm when i get it. if that one works, i will keep it. The one i got from AMAZON is going to be returned since I can't use it.

I would guess that Dual SIM Dual Standby for 5G is coming with Android 11. It was the case with the OnePlus phones and perhaps that feature isn't available with Android 10. Are there any Dual SIM 5G phones with Android 10? This article helped explain the situation (along with the comments below) Android Authority Dual SIM 5G phones

Hopefully the wait for 11 isn't too long

I got a UK version XT2071-4 and can report it is a true dual sim phone. Box shows dual SIM’s and I was able to load my US ATT eSIM and my Starhub nano sim on the phone and it works. You can’t use 5G in dual sim mode - probably something about the modem but it works great in 4G LTE with both sims. The global version is missing a few US specific bands though, running on ATT, not missed very much. So far so good. While the build quality isn’t as good (more plastic) I like the smaller form factor over the z-flip and the close to vanilla Android is nice. Happy camper now with full dual sim model - the us model I got from Amazon is going back. Now I just need a decent case...

Question Dual Sim North American For OP Pro 9

The specs page says Pro 9 has dual Sim but all the press reviews say that the US Version will have only single sim. Does anyone know? If 9 Pro unlocked NA version is 1 sim I'm pretty bummed and pissed off, especially since my order tech sheet says dual sim.

I was just looking at the spec page on their website, and it says "Single nano-SIM slot". Fire up my VPN and go to the UK page, dual sim. Also, black version not available on US store.

I'm currently on the fence, mostly cause my current phone works and performs fine. But if I do, I'll post here.

I can report, I just got my US variant (AA) and the dual sim tray slot on the backside like normal had a plastic bar preventing the use of dual SIM...I wonder if it's also disabled in software as well if one were to get a dual sim card tray...

I just tried my dual SIM tray from my OnePlus 8 Pro and it will only recognize a SIM in the front slot. I assume the functionality is disabled in the rom.
BTW, the 8 Pro SIM tray doesn't quite go in all the way, it has a thicker red gasket for sealing than the 9 Pro does. It still works, just not flush with the body of the phone.

I tried this as well, same result. It is hard to remove the 8 Pro SIM tray from the 9 Pro if you push it in.
Is the international ROM available to flash? I want to see if flashing that will make it recognize the second SIM with the 8 Pro's SIM tray.

I am very interested in this as well. I pre-ordered this phone because it said it was Dual-SIM for the USA. The following day, they edited it back to single-SIM.
If this can be worked around via getting a dual-SIM tray and flashing the global ROM, maybe I won't have to return it after all.

I can't believe we even have to have this discussion with a $1000 phone from a brand that has always had dual sim functionality. Argggggg...... It's going to make my head explode!

Right? The whole reason I splashed out for a carrier-free "premium" phone was to not be held down by any idiotic restrictions- but lo and behold OnePlus bent over backwards for T-Mobile. The worst part is that it's literally the same hardware, we just got a single-slot SIM tray and software to lock us out of the second slot.
It boils my blood that you can see the second set of SIM contacts in there and can't use them without jumping through hoops.
Mine's sitting in the damn box still, because I'm not using it until I know I can utilize both SIMs I have on it.

I suspect it's Verizon's fault to forcing it as Single SIM on the software side. Verizon gimped previous Android models in a similar way previously. Pixel 3 eSIM was disabled on Verizon-sold models, and they forced OnePlus to make separate variants of the OnePlus 8 for both Verizon and Visible.
They knew OnePlus would want it certified for 5G mmWave, and that was probably Verizon's 'terms' for getting it cleared.

This is actually a very good point that I hadn't considered. I hate how anti-choice the US wireless market is.

carbondog said:
I am very interested in this as well. I pre-ordered this phone because it said it was Dual-SIM for the USA. The following day, they edited it back to single-SIM.
If this can be worked around via getting a dual-SIM tray and flashing the global ROM, maybe I won't have to return it after all.

the second sim does not even fit in the the sim slot, it kinda looks like a microSD can but I don't have one to try.
Yeah I was kinda upset about this too, b/c I used my OP7Pro for personal and work phone with 2 sims.

The tray has been deliberately rendered useless on the second side. I tried it with the tray from the 8 Pro which fits two SIMs properly, but the software won't recognize the second SIM.

So frustrating. US telcos need more consumer-friendly regulation so they can't engage in anti-competitive behavior like this.
I put mine back in the box. Offering it to my wife to use, and if she doesn't, this is going back for a refund. Ordered the exact same phone from Amazon Italy, that should have dual SIM. ETA Apr 1-2.

That's not a bad idea, I think I'll do the same since I know my wife doesn't need dual-SIM. She probably won't want it though, haha. Let us know how that works out, if it's smooth sailing then I might just do that as well. I wish I knew this before ordering from OP directly, I'd have just gone to Amazon first.

Just a heads up bro.
If you live in North America like me ordering the OnePlus 9 series from Amazon Italy makes no sense as their variant is UK version which misses many LTE & 5G bands that we need in USA & Canada! I almost put the order through before noticed that is a UK variant.

The bands are almost always different. I think they do it on purpose so people in North America are stunted if they do a gray market purchase.
Why does the North American models have 5G band 78 for the EU but they don't have 71 or n260, etc.. They do it on purpose to screw us over.

Damn, man- this got me thinking, so I threw together a quick comparison graphic of the bands, which are missing in their respective models. Top is from the US OP page, bottom is from Spain's.
I was planning on using mine with Verizon, looks like that might not be a good idea.
Looks like the NA version should work in EU with minimal problem, but the EU version is missing many NA bands. 100% due to carrier pressure, disgusting.
If anyone can manage to successfully enable the second SIM slot of a NA variant, that looks like the way to go.

I search around and found that iphone US version are also single sim and they are able to make it to dual sim only if they open the phone and replace the actualy sim inserted piece on the motherboard. I watched the tear apart video of oneplus 9 pro which the sim card piece on the motherboard is also detachable without remove the whole motherboard. I think the would work. Simply use a dual sim tray would not work.

Question E-sim support

Hello anyone have any updates as how will be able to have esim or second physical sim activated on 926w (Canada) bought direct from samsung ,all discussions seems to hit a dead end
I really need at least 2 sim on this phone and getting a international version is not an option anymore
Thanks for any input
Happy New Year !

If you are in the USA, its not enabled. Samsung has told several people that it will be, once One UI 4.0 hits. We shall see

I lost hope on esim support for the U1 variant. Paying 2k for a phone and not having the option made me jump to the pixel 6 pro so I only have to carry one phone. Still holding onto the fold though in case it comes later on. If so, id jump from the pixel back to my fold.

What exactly is esim?

What is an eSIM card? How will it impact you? | US Mobile
eSIM offers a new way to load carrier information onto your phone without using an external physical chip, enabling you to switch carriers on the spot.

As European customer with Dual-SIM and eSIM Fold3 I'm not familiar, how Samsung and US carriers deliver the Fold3 in the States. According to your post, your fold is a single SIM device, is that right? Or do you have a carrier, that delivers eSIM support only?

In the USA it is one sim slot only. No dual sim, no Esim. On all carriers. Even unlocked

My like is a like for you but is actually a dislike for the content because it's STUPID that US does not use eSIM more widely.
Where eSIM's are used more than anything else in the US is for Watches. I have a Gear Watch 3 (my Watch 4 is BT only) and it ONLY comes in eSIM and my carrier (T-Mobile) didn't even blink and just activated it. So the SUPPORT IS THERE, just too lazy for widespread adoption.
Get rid of the SIM slot and one less place for dust/water to get in!!

Ummm... this is AMERICA!! Where very company looks harder at the Bottom Line rather than do what's good for the customers or people...
Hell, all you have to do is look at our Medical Practices (Hospitals, insurance and most of all, Big Pharma) and you can CLEARLY see it's all about The Great Chase for the All Mighty Dollar...

But by not offering dual-SIM you loose dollars, because people buy iPhones and Pixels ...

Just got the second 4.0 update the Jan. Security update. Samsung still blocking US Esim support on the Fold 3

Scamscum still blocking E-SIM? Ughhh. Glad I swapped my phone out for the Mexican Model.

Interesting, I thought Canada and Mexico have the same version phone and I know Canada does not have eSIM ability.

This Samsung store near me sell only international phones I'm sure they would ship u one just make sure what you buy will run on your carrier
Samsung Store - Sunrise, FL
