Using dual SIM tray on unlocked T-Mobile 7T - OnePlus 7T Questions & Answers

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.

Read the thread. TMO firmware does not support dual sim.

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.

HTC Desire 526 Verizon

I bought an HTC Desire 526 from Verizon to use in the USA. Can I use this phone in Canada with Koodo instead? Is it only locked on the CDMA portion to Verizon or do I need to unlock it to work in Canada on a different carrier?
Usually 4G LTE verizon phones are already sim unlocked, just need to change the settings from CDMA to GSM.
Try to change the sim card and check if it got connected to your network.

Thanks, I did that and the SIM card with Fido worked for talk/text, but I couldn't get the data to work. Any thoughts?
For Data add your providers APN on network settings =)
So how is the phones performance? Is the snapdragon 210 good enough to make use of the 1.5gb of ram and multitask?
Antutu came out as 18757.
Could you give a real world impression? These phones can get whatever score on a benchmark and then still fail to perform like the S6 due to whatever multitasking/ram issue it had or might still have.
Sure thing, just need to get me one nano sim first.
finally found a real review that provided a good look into many aspects of the phone
https://www.youtube.com/watch?v=o6d7A5TXZEE
the 210 doesn't seem that much different from the 410 (really shouldn't be since I believe its only 100mhz difference between the two?) although it does look like I might need to spend some more for something faster.
I wonder if it can work on USA GSM ?

Ended up just paying extra for a Moto E (currently $100 on amazon, even cheaper on ebay) and called it a day since I need root access. Might be worth it now that best buy jacked the price back to $90, leaving walmart as the cheapest option at $80.
Thx. I wonder if this one can be rooted.

That's strange, I did it myself and it worked no problems, just have to skip the whole initial setup from verizon/htc, keep hitting skip or omit until you're on the home screen.
Also spent a hard time getting a micro sim cut to nano sim to recognize it, if you can, get an original nano size sim.
it detects my sim alright and i can even see the sim services in the home menu but no network coverage

Verizon SIM in CARRIER UNLOCKED T-Mobile s8+ not working

Hi
I have a carrier unlocked T-Mobile s8+ and need to use a Verizon SIM in it and am getting errors trying to use a verizon SIM. The Verizon SIM is from another phone and is already registered. I put the IMEI number of the phone into Verizons web portal to test compatibility and it failed. Does that mean there is no way to get this combination to work? Does the IMEI need to be in the VZW database for this to work? Will flashing XAA guarantee this to work? Thanks for any help and advice.

do u have a tmobile phone, it is different than the carrier unlocked phone, those are 2 different models,
the carrier unlocked.. the sim is unlocked..
the tmobile is not carrier unlocked, and by flashing the firmware of the unlocked version, will NOT unlock the sim.. u will need to device unlock app with the tmobile phone 1st... and usually tmobile will NOT unlock unless u have paid it off and using on their system for 40 days..
others like me had it unlocked with days of service, cause we are tmobile customers for years already... I on the other hand bought the phone on ebay from someone who bought it from Samsung and the imei was not added to tmobile system and I had to call tmobile to add the imei which took about 3 days, then to call back to request the sim unlock which took another 3 days, the device unlock app unlocked the phone instantly...
that was my process for me to get the sim unlock... but if urs it not unlocked and is paid off, another way to get it unlocked it to give it to someone u know, let them use it and call tmobile to start the above process...
Hope that sums up what must be done...

Hi thanks for the explanation, I am pretty familiar with the differences between carrier (SIM) unlock and unlocked firmware as I have flashed Android in the past. I had the phone carrier (SIM) unlocked by T-Mobile through their app and I was still not able to use the Verizon SIM in my phone (not registered error). It turns out (and I found this out by reading through the many messages in this forum) that T-Mobile firmware apparently disables some frequencies that other carriers may use. Once I flashed the XAA unlocked *firmware*, I popped in my Verizon SIM and it worked like a charm. I hope this info is useful to someone at some time and I thank all of you for your contributions to getting this working. KUDOS!

Good to know, but sound weird, thought T-Mobile phones work for all gsm Sims just needing to change apn,
But now cdma merging with gsm, that's so much better as far as phones go, use any phone now from any provider.
Look how the s8 plus is all the same software and the same hardware, just different carrier stuff..

I thought it was weird too. Busted my head for a couple of days trying to figure it out. Is Verizon still CDMA? *scratches head*
Yes, their 3g and 2g networks are CDMA.
If you insert Verizon sim into T-mobile phone, you'll get LTE data, but you won't be able to make calls. Only data will work. T-mobile firmware support band 2, 4 and 13, so you should have data, but not phone service. If you don't have data icon, you'll need add Verizon apn.
FYI
Flashing the phone with G955U1 firmware fixed this issue. I am now able to use this successfully on Verizon.

Anyone using this on Verizon yet?

Just want to verify this phone works appropriately with Verizon. I see nothing on this from Verizon's website and nothing more than a few mentions in press releases. Does the lte-a work correctly? Can we access Verizon features like video calling? Does Verizon staff give you problems trying to register the phone?
Can't wait to hear some first hand experience.
wondering the same thing actually

Looks good enough for me. I'm about to order one from clove, will update when it gets here if this thread still needs some answers. I hope volte works. Wifi calling would be a cherry on top.
Yup! Having it working on my XZ2 Compact. Didn't originally want to connect, so I flashed the OEM+OEM_Other.sin files from the US version and now I have Verizon working without a hitch. VoLTE is enabled for Verizon by default since it can only connect over LTE to begin with, but no WiFi calling. That being said and it being a dual SIM device, my secondary T-Mobile SIM has access to neither VoLTE or WiFi Calling. So I have calling set up for Verizon and Data over T-Mobile. You're able to do dual LTE standby on this device.
So now that this works with Verizon I should be able to buy the duel sim version and run both my personal At&t sim and my Verizon work sim card in this phone with duel standby? No flashing any software?

Does flashing these have any affect on DRM keys and such? I'm going to be getting a H813, but with UK software from clove so I'll need to do the same thing I'm guessing.

I believe so. H8324 is the Asian dual SIM and H8314 is the Western single sim. I wasn't checking all the bands but both phones have all three of Verizon's LTE bands supported

Just ordered the duel sim version and should have it by Wednesday. I currently have both an At&t personal phone and a Verizon work phone. Plan is to combine them both in this duel sim phone and only have to carry one haha. If it doesnt work out for whatever reason il just try google voice for my work number i suppose.

Having some issues with my XZ2 Compact Duel sim. With At&t I am only getting H and H+ connection and Verizon I cant seem to get anything to work. What APN did you pick for your Verizon sim, i have choices of CBS, FOTA, IMS and Internet.
So I have some more information that may help someone or may not. After talking with Verizon in depth about my issue with connecting to their service they have determined that the XZ2 Compact will not work on their service. Even with it being labeled as an Certified Open Market device on their own site and even being listed as Verizon Compatible on Bestbuys site and many others. They said noone there has any knowledge of the device coming to Verizon at all and were confused about it being posted on all the sites as being Certified. So i suppose it just wont be compatible lol. I guess im porting my 2nd # over to at&t and just not dealing with it because im sure as heck not going through the hassle of sending this phone and the chargers and cases back lol. If anyone has any success on getting this connected with Verizon please post, but im not hopeful lol.

I tried sending him a message but haven't heard back. I'm assuming perhaps he was mistaken about what phone this post was referring to.
I believe carol_vzw is a Verizon employee who maintains this list: https://community.verizonwireless.com/docs/DOC-2843
The H8314 is listed on here as officially supported, but H8324(dual SIM) is not. You could try messaging her on there to see if they can add the H8324, or find out why it's not compatible.
Edit: looks like you've already seen this based on the comments

Yea the crazy thing is while talking to Verizon support yesterday i referenced that post and also Bestbuy having it labeled as for Verizon as well as the phone being posted on their Showcase directly on the Verizon site lol. The support guy kept putting me on hold and said he was taking the info as I was giving it to him to another support team directly and that they were all baffled at this information as none of them had any knowledge of this phone let alone it supposedly being compatible with Verizon at all. After about an hour into the call a woman picked up the phone and directed me to attempt to put my new sim card (when i swapped to this phone i had a micro-sim from my old phone not a nano-sim which this phone needs) directly into someone elses phone that has Verizon and attempt to activate the sim card on their phone, then attempt to reinsert it back into my phone to see if the network picked up. I will be attempting this in about an hour when I see a friend who has Verizon. I will update on whether this works or not.

If its any hope, I had a similar situation when I was trying to activate my Nexus 5x on Verizon. The people in the store didn't know that it existed and had no instructions on what to do. Also my first nano SIM phone, and they couldn't get it to activate. That's when I learned to never go to their stores for technical help. But it was worth it that time because they let me keep the sim card and later I was able to get someone on their tech support number who was able to activate it remotely. It could just be that the phone is new and information hasn't gotten around internally. Verizon seems pretty bad about that.
My xz2c single sim package got lost on Wednesday by DHL ? but I'm going to be dealing with this soon
Well no luck trying to activate the Sim with another Verizon phone. It seems that the phone just isn't in the Verizon system yet.
I have a UK single sim that I'm having no service with Verizon. Not sure if it's due to the phone being from the UK or something else with Verizon maybe. Trying to flash the US firmware but having problems with Newflasher.
If I have any luck I'll post back here.
Just posting for others who may be curious; I was able to get the phone working on Verizon today. Using the sim from an already activated pixel 2 initially worked for data and calling, and sending text messages, but I could not receive text messages. I grabbed an updated sim (says 4G LTE on it) and activated it on the pixel 2, then moved it to the xz2c and currently have everything working. It's only been a few hours so we'll see if it stays like this or if it goes the way of the htc U11 and has problems every couple of weeks. I'm using the verizon approved H8314 single sim model, not the dual sim model.
Interesting, thanks for the update! I'm using an activated sim from my Pixel 2 as well. It says 4G LTE on the sim too and my model xz2 compact is the same H8314. So maybe it is the UK firmware in my case, I'm going to keep trying to figure out my drivers issue this weekend to flash US firmware and see if that helps.

Are there variants of the H8314 not compatible with Verizon?

Just got an H8314 model and verizon is unable to activate the phone. Are there multiple versions of the H8314 that I should know about. Shouldn't all of them be compatible with verizon?

Did Verizon offer to activate a new SIM in the device? Did you check the IMEI?
I took it to Verizon to get activated and it didn't work, nor did anything I tried. They punched in the IMEI several times and it never came up as working with their network.

Same thing happened to me today.
Last night the tier 2 tech guy told me I needed a new sim card.
Anyone else have any success activating it?
What's the trick?
The Verizon website says that its certified for use on it's network.

There are 2 versions of the H8314, one that works with Verizon and one that doesn't (international). Unfortunately, the international ones are easier to find online, if it says it doesn't work on Verizon/CDMA despite it being this version, then believe it. The American variant seems to be a bit more expensive than the international version.

Aren't the internal components the same?
Couldn't you just flash the US version of the firmware?

I don't know. My firmware flashing days are behind me to know this for sure.

Question Will we ever see dual-SIM enabled on the NA model?

We can finally order dual-SIM trays via eBay as of today. What are the odds of being able to enable that second slot?
It might need some time. I read from other post that oneplus 8 pro took a year before a low that feature. now oneplus 9 pro only have one sim tray so it might talk even a longer time for them to release that feature. I am more depending on the people who know how to customize the rom and add feature . So just stay tune at different forums.
OP9Pro normally comes with a dual SIM. Just flip over your sim tray and insert the second sim. Voila!

That's great news. I returned by OP9P NA variant, but don't have a global variant yet. Shouldn't it just work with the NA variant if we flash a global ROM on the same device? It looks like it has pins on both sides.

Not that simple I think. I already flash to EU tom but it does not second sim in the settings. I think it might need wire flash of all components including baseband

Oh no. Does OnePlus publish those components, or are we out of luck until someone figures out a way to get them? The EU variant I have on order doesn't support one AT&T LTE band, so would much rather use an NA variant with dual SIM enabled.
If the EU variant shows up at my door before someone figures out how to make dual SIM work on the NA variant, then I will just use it even with the missing LTE band.

I saw one guy on Reddit complaining of the same situation we're in- ordered the phone when it said dual-SIM and trying to return it afterward.
He claims OP customer service said dual-SIM would be enabled via update in the future. While I hope that's true, it's the first and only time I saw that said anywhere. Could've just been said to try and avoid return. Even if it does happen, it'd probably be a ways off.

I chatted with OnePlus customer service two different times. Both agents tried to talk me out of wanting Dual SIM, but were very clear that it is single slot only for the US. One even cited spouted some bull**** about doing that to optimize 5G performance on US networks.

I guess we have to wait to see if anyone can figure out how. At least, just upgrade to a newer version of EU tom does not work. Not sure if you for flash everything and reset from adb is the same
i have a bnib stellar black chinese version dual sim 8/256 oneplus 9 pro for sale. I am in SF bay area.
Will it work if i have a Dual Sim Oneplus 9 from Malaysia, install NA rom to open more BANDS ? The malaysia OnePlus 9 has the same 5G bands as in UK, but lack of some US 5G bands like n71. All CN variant do not have B13 band, therefore, not supporting Verizon LTE nicely. All ebay sellers who claimed dual sim with 12GB RAM and 256GB storage are mostly CN variant. I'm better off with EU/UK or MY. Hong Kong spec is the same as USA with dual sim. If anyone wants a dual sim and want mostly all US bands supported, Hong Kong Oneplus seems to be the right fit. Only if we can get it from HK

wait what?! both SIM fits in the same compartment ?
wouldn't that be too tight?
mine only has a slot for 1 SIM
The dual sim versions have 1 sim on each side of the tray.
Mine came with dual sim out of the box and is working perfectly.
I really like how I don't have carry around 2 phones anymore.

Do you have the US version?
I was very disappointed that the US version didn't come with a dual sim. I ordered mine at launch, when their website said that it had it.. Anyway, I finally figured out an acceptable replacement option for mine. I did have 1 sim for my personal number and a second sim for my work number (worked great on my OP 6T for a couple of years now). After playing around with things, I finally ended up porting my work number over to Google Voice (1 x $20 fee) and installed the Google Voice app on my phone. Now I essentially have 2 #'s on one phone, just like having a second SIM, but no cost to my carrier. I can receive calls and txt's for the # I ported to GV. Wasn't quite the solution I was hoping for, but now I no longer pay for that line.

I don't think is a US variant. As far as US Variant is concern, is single SIM. Anyone that is using Dual sim could be CN or EU/UK Variant. If it is indeed a US variant, then I'm interested to know where the source to get it then . Those variants have fewer 5G sub-bands compared to the US except HK. I just hope that Oneplus has the hardware embedded and is just a matter of software activation. Samsung Note20 new firmware patch also opens up their eSIM support.

You do know they make an app called second line right? So you don't need to pay for 2 plans
