exciting? wtf is so exciting about having a second sim haha. i never understood that. i'm not trying to be rude or dismissive... i'm sure my tone isn't coming across the right way. and i know everyone has a different use for a phone. but i've had dual sim with my op5 since release day and never even opened the slot after sticking my tmobile sim in there on day 1. i think i even had dual sim with the op3t but i can't remember. can't be bothered to google.
[OnePlus 6T  Guides, News, & Discussion] mang0:
Well, for people who have both business and personal phones/numbers, you could use dual SIM and only have to carry one device instead of two, while maintaining the ability to call and receive calls from both numbers. Or if you travel overseas a lot, you can put a local SIM into the second slot which might cost less than an international plan with your regular carrier. There are plenty of uses of dual sim, even if you don't personally use it!
[OnePlus 6T  Guides, News, & Discussion] djkinetic:
I meant exciting time in regards to development opening up for the T-Mobile variant.
[OnePlus 6T  Guides, News, & Discussion] kramer987:
i know. as i said, my intent wasn't to be rude or dismissive of the uses. but anyway, since we are here talking about the tmobile variant... i assume we are all on tmobile. and doesnt every tmobile plan have unlimited texting and data in like every country? i know that any country i've been to in the last 3 years i havent had to worry about those things. i know i know, some people like to make voice calls. but even tmobile's slow (free) international 2g data lets u make voicecalls over whatsapp or hangouts. but... i know i know. people like to call local numbers when abroad.
[OnePlus 6T  Guides, News, & Discussion] acmerw:
it's possible, just need to flash with msmdload tool full wipe mode, flash qcn and write two imeis with some box by diag mode. same was with s7 g930f, hardware was here, but second slot disabled by software and second imei was absent.
[OnePlus 6T  Guides, News, & Discussion] aznrmx1112:
Lets say we get the international rom installed....we get a sim tray that has 2 sim card slots, devs find a way to enable said 2nd sim slot,

Think we are SOL if OnePlus didnt assign a second imei even though the hardware is on the OP6T Tmo version?
[OnePlus 6T  Guides, News, & Discussion] djkinetic:
Assigning an imei privately I'm pretty sure it's illegal though.
[OnePlus 6T  Guides, News, & Discussion] pkadavid:
You answered all of your own objections about not needing a second SIM. I'm on TM but also have a second SIM when I'm in Europe. Additionally, people in the US can take advantage of dual-SIM phones so that they don't have to carry a personal and work phone at the same time, which was mentioned in a previous comment.

Dual sim support would be fantastic for when my wife and I go visit her family for a few months out of the year, and to teach English. We usually just get a basic phone while we are there, or I swap sim cards in the phone.
[OnePlus 6T  Guides, News, & Discussion] Krunk_Kracker:
dsds denotes international....

Edit

Whoa, wait. It's commented out. Can you remove the comment? It's the pound sign, or hash tag as you whippersnappers call it.

Who's the guy with the CM7 avatar, he has a rooted t-mobile op6t, he may be able to test.

Edit 2

Injust realized only the comment itself is commented out, not the actual config....

Its gonna take more than a build prop editing the kernel and MODEM is different from the intl model etc.

I know, but I was curious if it might turn something on in the settings. Not that it will work, just was hoping experiment
[OnePlus 6T  Guides, News, & Discussion] tech_head:
Oh, I know that, I just thought it interesting that it is there at all.
[OnePlus 6T  Guides, News, & Discussion] krabman:
The fact that the connectors are there does not mean that the modem suppoorts dual sim (as is) or that it has a 2nd IMEI. It would have them in any event because its a cheaper way to manufacture. An example would be cars which often have wiring installed for options that are not installed because its cheaper to manufacture that way despite the waste. I'm not raining on any parades here, just saying that there seems to be some belief that it is reasonably positive proof that dual sim is a rom away here and that isn't the case. I'm hopeful you guys get your goods but the carriers go to great lengths to control the wireless market and it would in no way surprise me if Tmo specifically requested and got a phone that does not have that 2nd IMEI. Again, I'm not fear mongering, I've no idea what the truth is here, I'm just saying I wouldn't be counting my chickens just yet.

An XDA user was able to flash the International ROM to his t-mobile 1+6T and confirmed that IMEI 2 shows up on his device. He was not able to fully test it though because his actual SIM tray only has a spot for one card.

How do you submit to OnePlus for the unlock bin?

---------- Post added at 11:40 PM ---------- Previous post was at 11:27 PM ----------

Hello all just looking for a little help. I called and tried to get unlocked. They said they could only do temp and not permanent. So I went to the app and requested temp and it went through. I restarted my phone and the app was still there with only the permanent option. Tried requesting permanent and no go. Left it at that and was happy with just temporary unlock. However now the app is gone unexpectedly and the oem unlock in Dev is still grayed out. When you are unlock shouldn't the oem unlock become selectable or do you have to fastboot for that?. How do we make this phone take OnePlus updates rather than waiting on TMobile? Thanks
[OnePlus 6T  Guides, News, & Discussion] d3vilskid:
It's not flush, the bottom edge sticks out a bit but Sim card one reads. I was the one that tired it and posted about it. I didn't take a picture though.
[OnePlus 6T  Guides, News, & Discussion] mang0:
There's a good guide here: https://www.xda-developers.com/oneplus-6t-unlock-bootloader-root/

Scroll down to the TMO part.

The OEM unlock in dev settings only becomes accessible once the device is permanently unlocked. Sounds like you are still temp unlocked. Although I'm not sure what's going all with your Unlock app.

I have 9.0.5 flashed, non-international (same IMEI for both), but used a TMo & Verizon SIM and both worked.

Where can I download the international ROM? Did we figure out how / if we need to flash criticals so OTA will work and essentially turn our TMo6Ts into normal 6Ts?
[OnePlus 6T  Guides, News, & Discussion] rootmaster96:
The OTA for local upgrade is located directly on OP site: https://www.oneplus.com/support/softwareupgrade

As for the criticals, check the thread that you linked. My suggestion is currently being tested and an answer to your question should be provided shortly

Hacked up my sim tray for two cards.

Both cards are seen as active.

Voice works on both.

SMS works on both.

MMS (and all data) only works on the default source.

Seems to be both active at the same time, which has me slightly concerned. Going to make a backup of my persist tomorrow and flash the persist from the global rom.

**NOTE** without knowing exactly how this works, you might be blacklisted by one or both carriers. The fact that both are active at the same time on both networks is typically not a good thing. This is working more like an active connection than a standby connection.
[OnePlus 6T  Guides, News, & Discussion] KOLIOSIS:
So,incoming & outgoing Voice/SMS works on either SIM,regardless of slot?

Also,are you prompted as to which number you use before placing an outgoing call/SMS?

Which SMS apps(s) have you used?
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Only tested incoming calls. I have a T-Mobile SIM in slot 1. AT&T in slot 2. Called/sms/mms from my laptop using Hangouts on my Google Voice number.

For out going calls one of the settings is to ask which number you want to use, or default to slot 1 or slot 2.

Used Google Messages for text. The send button is a SIM icon that you can hold to select a different number. There's also a smart reply in the SIM settings that will reply to calls and texts from the number was called or messaged.

MMS would only work on whatever sim I had set for default data. I would get a loading icon in the text thread that an mms was coming, but it wouldn't come until I swapped the data source. Tested over mobile only. Disconnected wifi while testing.

Since I was using my GV number. I was sending to two different numbers, but it was showing up in the 6t as one text thread. Under the messages it will say "from T-Mobile" or "from AT&T" and it would change my default response source to whatever number was texted last.

*Edit: clarified how smart reply works. If someone calls or texts your first or second number, it will automatically reply with that number, even if it's not the default.
[OnePlus 6T  Guides, News, & Discussion] tech_head:
You have described how an unlocked 6T works.

You can receive calls and texts on either number, send on either number.

MMS only on the line selected for data..
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Well now the question comes on what happens with the imei. I've been running this for a day and a half and haven't been blacklisted on T-Mobile or AT&T.

I have Digits for T-Mobile, so I might see what my account looks like when I have both sim cards in there. It's displaying only one imei in the settings (with two sim slots). AT&T is my work sim and I don't have account access, so I can't see what imei is being shown on the account.

To be safe I will use one sim card. Use it in one slot. See what imei is shown on the account. Then I'll pop the tray and swap and see what it says on slot 2.

I'll post my results later today. But so far I've gone all day with both sims and no issues.
[OnePlus 6T  Guides, News, & Discussion] infamousvincci:
I dont think theres a reason for them to black list you. It is "unlocked". They can see your imei but they wont see that that imei is being used by other network. Atleast from what i understand. Assuming you have the same imei on slot 1 and 2.

Like i said, att cant see that u use tmobile on that imei and vice versa.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
I was going to use my Digits SIM and look at my T-Mobile account and see what imei is listed for both numbers.

I'll instead just use one sim and switch slots and see what imei shows up in the account.
[OnePlus 6T  Guides, News, & Discussion] aznrmx1112:
Any update on this? I too have hacked up my sim tray to take two with no issues...same imei showing up as well for both sims but both appear to be working like your set up. Def. agree with you as well to err on the side of caution when using both sims on the same imei to avoid possible blacklisting.

Any other experts on this that can attest if we can use the second sim tray without any issues? AFAIK the int. OP6T has two dedicated IMEI #s and the TMobile flashed with int. 9.0.5 OOS only shows one/same imei and has not been shown to have two imei #s, atleast yet. ;D
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
Two days now. No blacklisting. Still haven't used two cards on the same network. Still didn't check the imei on the second slot to confirm it's really the same. Yes it tells us it's the same, but I haven't verified by checking my providers info yet.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
I don't think the IMEI numbers would matter unless both sims were from the same network.
[OnePlus 6T  Guides, News, & Discussion] aznrmx1112:
So ideally we are good to go as long as we don't use say to 2 sims/numbers from the same network? I personally just want the ability to use when I travel internationally so Im not worried about the day to day, but would be cool to use without any issues/blacklisting.

Hoping to get some more data points on this as would hate to hear if something only happened to [MENTION=1459374]hartleyshc[/MENTION]'s phone due to using two different sims on the TMO version variant.

Also thanks for your input [MENTION=4204048]Dark Nightmare[/MENTION]. That is what I was thinking too, just wanted to test the logic with others here. If the majority of us are on the same page, we must be right, right? XD
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
The IMEI is similar to an IP address in a way, as both networks are separate, I highly doubt there would be any conflict causing blacklisting, only cause I would see for them to be blacklisted would be networks like Verizon not wanting the devices on their network, which they seem ok with or two sim cards from the same network being in the device, hence the device would show up twice, which would look like the IMEI was cloned, which is clearly illegal, so blacklisting, though I have heard of people copying IMEI numbers for scamming purposes on t-mobile years ago and they didn't blacklist until the scammer reported the device lost. So yeah, my 2 cents.
[OnePlus 6T  Guides, News, & Discussion] aznrmx1112:
Appreciate the clarity on it all. As we have a lot of new people coming over from iPhones for the first time or people doing a bootloader unlock/flash a rom for the first time with these 6Ts, I personally think its awesome to try and provide the best help we can with warnings/clear instructions and correct info to have people make informed decisions. Def. agree with you and think its probably safe, just erring on the side of caution. :)
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
So I can officially confirm, the T-Mobile OnePlus 6T is a true dual sim device.

The T-Mobile variant has two different IMEIs even though only one is displayed in the settings.

I swapped my T-Mobile SIM to slot 2 and I got a different IMEI than my primary. My primary ends with an 8. This is slot 1 and is what's shown for both sims in settings and is what's printed on the phone/box.

The secondary SIM imei ends with a 0, the rest of the number is the same.

So yes, to answer the debate, the Tmo 6t technically has two IMEIs even though only one is shown at a time.
[OnePlus 6T  Guides, News, & Discussion] Dark Nightmare:
Maybe if we can flash criticals/persist the second IMEI will appear as normal?
[OnePlus 6T  Guides, News, & Discussion] matistight:
Fun fact, many phones have dual sim contacts but never support dual sims. For example, this is the same thing with the Nexus 6P, many US LG phones, and the Razer Phone (which doesn't even have a dual sim variant.) Like stated before, dual sim would require a dual IMEI as well. The annoying this is that you can't even put the sim card in the secondary slot, even if you're trying to read just one sim...annoying to me but really who cares.
[OnePlus 6T  Guides, News, & Discussion] hartleyshc:
The second slot for the Nexus 6p was never enabled.

Our second slot is enabled and fully active. All you have to do is flash the global rom to enable it. There's two sim slots and each one has an imei.

As for the SIM tray, an exacto knife and a small file can solve that problem for you. Or you can use a OP6 tray until 6T trays become available.
[OnePlus 6T  Guides, News, & Discussion] intrusdave:
I can confirm that the T-Mobile 6T is dual SIM. After flashing with the global rom and swapping the sim tray with my OnePlus 6 (Not a perfect fit) both sims are fully functional. I was able to call and text from both.
[OnePlus 6T  Guides, News, & Discussion] djkinetic:
Further comfirming the 6t for tmo is dual SIM enabled after flashing the full stock 9.0.0.5 global rom. The IMEI of the 2 slots is indeed different..checked my tmo account to see..the likely reason the os is reporting 1 sim is because we still have the tmo critical partition and not the global critical if we can flash the critical partitions later on then it's likely we will be able to completely convert our tmo variants to global..one thing I have noticed is some play store apps say incompatible device after switching to the global rom. Here's some screenshots.

Well... I ordered a op6 dual sim tray off aliexpress a week ago, so will just wait for that.

How many days later? Was it 2-3 weeks?

Edit - I am chatting with Jomark at the moment and he will not issue a dual sim tray.
[OnePlus 6T  Guides, News, & Discussion] kramer987:
they are giving me the same shpeal about he tmobile variant being a single sim tray phone. so i said my only alternative it to cut into the tiny tray and risk slicing my fingers haha. let's see if it gets approved.

edit: they put in the request. i'll find out in a few days or something whether it is approved. it seems like i'll definitely get something, but it is unclear whether they will send me a single or dual sim tray. i'll have to wait and see

edit 2: they also asked me for the variant of the phone -- midnight black or glass black or whatever.
[OnePlus 6T  Guides, News, & Discussion] ozzmanj1:
I am being honest and told him I was completely unlocked and running internation 6T software on mine and that both sim cards are active and users (did not say where online) are able to use both sim cards on their somewhat TMO unbranded 6T phone. Waiting to hear back from him.

Edit - And got shot down, saying they do not give out free dual sim trays or any sim trays for that matter. I am going to wait a bit and try again hopefully better luck with someone else
[OnePlus 6T  Guides, News, & Discussion] kramer987:

[OnePlus 6T  Guides, News, & Discussion] dhoang:
Just chatted with them. I was 100% honest. I told them that my phone is unlocked as well as its bootloader. I told them that i am running the international rom on my T-Mobile variant, which supports dual SIM. They asked for my address but will only give me a single sim tray not dual. Oh well...I tried.
[OnePlus 6T  Guides, News, & Discussion] kramer987:
so take the new sim tray that they will send you and use it as a test subject for attempting to convert it into a dual sim tray. aka, stab it with an xacto knife until you are able to cut out enough lol

I just tried as well,both on chat & phone,got shot down.

I offered to pay whatever (within reason,$20 tops sounds fair,considering it's new/etc...) & cover shipping/handling costs.

Just as w/others here,the conversations revolved around which model I have & they seemed willing to replace a Single SIM Tray,as I have the IMEI/etc...... as proof of ownership.

I'm not going to bug 'em much more about it,they'll pop-up on eBay & the like soon enough.

In the meantime,I ordered a Dual Tray for the OP6 from Amazon for less than $7.00 shipping included.(Reported to work,but,doesn't set perfectly flush)

It won't update with OTA. You'll have to manually flash it when an update comes. (a TMO > International conversion)
[OnePlus 6T  Guides, News, & Discussion] Nileshdd:

Not necessarily. You'd probably need to clear cache, but you could keep your data partition and install in place.
