OnePlus 6T Dual Sim Question - OnePlus 6T Questions & Answers

I am considering a OnePlus 6T so I can consolidate my two phones to one. I currently have Verizon and GoogleFi.
Will I be able to receive calls and text simultaneously on both numbers?

Yes.
Only one number controls data.
I use Verizon and T-Mobile.
You need to chat/call with Verizon and have CDMA_Less added as a feature to the line since there is no CDMA on the 6T.
It works great for me.

On the international version, you can switch data back and forth at will (there is a tile to do that quickly) but if you prefer, you can even enable dual 4G networks for both sim cards!
Cheers!

my understanding is that your Google fi Sim will default to T-Mobile only if you use it in a OnePlus 6t. you will lose the network switching benefit to Sprint and US Cellular that you get on a Google fi approved phone. So, effectively you'll have T-Mobile service on one sim and Verizon on the other.
I have heard that if you use a Google pixel with Google fi and have it set up as an esim, you can use a secondary Verizon sim in the open SIM tray. That would mean you'd have the full benefits of Google fi service as well as Verizon. As noted below, only one sim at a time can control data. Long and short, you need a pixel phone to do this because the OnePlus 6t cannot fully utilize Google fi service.
Take everything I said above with a grain of salt because I do not have a pixel phone. I am however using a OnePlus 6t with T-Mobile and XFinity mobile. The problem with my setup is that Xfinity mobile only gives me calling. I cannot receive text or use mobile data with my Xfinity Sim. This may change later once Xfinity approves "bring your own Android phone" to the service.

If this works exactly as you said it would be perfect because I don't care if my Fi sim ever connects to data, in fact I would like it to never connect since I have unlimited with Verizon and Fi costs me $10 per GB.

Thanks for bringing up that point it is very likely important to someone but for me my current Fi phone is on TMobile 99% of them anyway because sprint has very little coverage in my area. US cellular is non existent for me as well.
I have a Pixel 2 Xl now for Verizon and I thought about getting a Pixel 3 when they came out. I spent about an hour on the phone with Google about this subject and unfortunately according to Google (and a few threads here on XDA) the Pixel will not allow you do have both Esim and Sim active at the same time. So if I have my work number (Verizon) active, my old personal (Fi) will not receive calls or text and vice versa. You have to manually switch the service to use each.

I guess Gixel 3 allows using eSIM and normal SIM simultaneously with Android Q update. Bear in mind there's still a single radio so while call on one SIM is ongoing any calls on other SIM can't be known.

I have fi (tmo) and unreal (att) works perfect. Only thing is messages sometimes will fail to send. Using hangouts does fix it, only problem is that Android messages is a better app in general

works great on Tmo and ATT. using Google Messages, Google Dialer and data works fine. i have rooted converted TMo OP6t with dual sim tray. Tmo VoWifi/VoLTE works, but ATT only support VoLTE on OP6t.

Question while using Google messages. Do both of your phone numbers pop up everytime you try to type a message it's super annoying for me and the only reason I stopped using it..

Used to do that, but it stop doing it and just works. Not sure what i did. I forgot. sorry. Disabled the stock messages app and default to google messages.

I have ATT and picked up a Fi sim over the weekend. Took me a while to get it activated (had to pop it in my OP3T for it to actually work, the dual sim feature didn't play well with activation). ATT is primary and Fi is secondary for everything. I have dual 4g radios enabled but that only enables VOLTE for Fi, but the actual data is used through my primary sim (ATT). SMS messages were not received if hangouts was disabled for SMS and Fi was not set as the primary Sim for SMS. Aka SMS doesn't work unless you make Fi the primary SMS sim or use hangouts for SMS, which is fine but defeats the purpose of using the dual sim features in your default SMS app (tried this with both textra and google messages).
As someone else said already - android Q will bring dual sim dual standby to the pixel line.

And you need the dual sims tray from ebay or oneplus, since Tmo OP6T is only Single Sim tray

Just say no.
If you need dual SIM functionality, just but the international version.
Buying the T-Mobile version mead a pain to get it unlocked before the 40-50 days.
If you flash the International ROM before then you will need to flash back to stock to unlock the SIM.
Buy the right version from day one.

I did not have to wait 40-50 days to get my t-mobile variant unlock. I reached out to tmobile via twitter and paid 2 months of installment ahead of time and received a permanent unlock from tmobile. I currently have a verizon sim(Work) and tmobile sim(personal) in mine with the international rom.

That is hit or miss.
There is no guarantee that you can get an unlock.
So if you buy with the knowledge it may take 40-50 days for an unlock you can't be angry.

Yes, that's why I ended up getting it directly from oneplus.com website... Unlocked, no hassles, two sim cards.

T-Mobile Nexus 6 works on all carriers CONFIRMED

Hey guys,
I just purchased a nexus 6 from t-mobile and popped in a sim from att, sprint, and Verizon. I can confirm all 3 worked flawlessly with no problems.
At the device start up, i did skip the part where it tried to activate on the network the sim was from.
If anyone has any questions feel free to ask.

Are you seeing the issue of voice + data not working at the same time? When I'm on a call on Verizon, Wi-Fi works, but mobile data shuts off... is this just Verizon, or is this a "feature"?

But what I do want to know is if Verizon will whitelist the imei numbers . because I am soooo ready to pull the trigger to buy at a tmobile store. Did you have to activate the tmobile first? That's what the rep is telling me here

Unless something has changed with CDMA technology, the Verizon phones shouldn't be able to use data while on an active call. I know they are working to get that working with some new LTE standard but I haven't heard anything about it being here yet.

I'm considering switching to TMo anyway, so I picked up 30 days of pre-paid with the phone for 45$. I plan to try both carriers on my commute, see how signal is on both carriers on the train ride, downtown at work, etc. before making up my mind, and this device makes it as easy as swapping the SIM out!
The issue I had, was I didn't have a nano-SIM. Verizon rep at the store told me there was nothing they could do... I told them if he got me a nano-SIM, that customer support could active it... He gave me a SIM and let me use their phone to call Support to activate it. The support person did a "SIM swap" for my existing device, even though my Note3 obviously doesn't use a nano-SIM.. but that's all it took to activate the nano-SIM, and it works perfectly.
I may be misunderstanding your question... I believe the confusion is that you don't actually activate the phone... you activate the SIM IN the device. You should be able to take the phone out of the box, and drop in an already activated SIM and all will work fine...

I know it works. My question is. Would Verizon block the imei or device I.d.s later down the road to where it doesn't work and only the imei that's been sold on Google play works.

Good luck getting your answer. If the device suddenly stops working on Big Red, I'll post here (as soon as I've completed my switch to another carrier).

Lol. Yea that's what I was worried about. I didn't want to buy it then down the road oh yea this I.d. doesn't work anymore.
I did not register my device on T-Mobile at all. Just popped the other sims in.
What I'm told is that carriers only care about imei when activating for the first time. If you just put your own sim in there they just can't see the device type which really doesn't matter unless you're looking to call them for support.
T mobile store gave me **** about buying the phone out right. I had to get a friend to add me as an authorized user on his account to buy the phone OUTRIGHT. So stupid...
Also, at T-Mobile the phone out right was 649 where everyone else is like 50 or 40 bucks more which was also sweet.
I also did not get bloat Ware on the phone from the carriers.
The devices CDMA identifier (MEID??) needs to be in the carriers whitelist so if the OP didn't place a voice call over either the Sprint or Verizon networks itnis not "safe" to to say it works on all carriers.
This is supposed to be one model for all of the US with 4 SKUs for the variations, and it should work but there is still the question of whether the CDMA carrier. Allows the phone on their network.

I can confirm I've activated my nexus bought directly from moto on both sprint and T-Mobile. Both voice and data worked with each carrier. Sprint takes a little more when than just putting the Sim in. They need to activate the MEID in their system. You can't just put an active Sim from another phone in and have it work.
Interesting..
Other users have reported the exact opposite.

Yep, talking about Sprint. IIRC, there were multiple threads on here saying you can only activate on CDMA carriers if you buy from them or Google Play.

Buying from T-Mo living in a non-T-Mo area
Yes. I must be one of the only people on here in the U.S. not living in a T-Mo area.
I just ordered from T-Mo (64GB MB). After much conversation and clarification, I've learned that one can buy a Nexus 6 from them outright, which requires also buying a $10 SIM activation kit. Since I do not live in a T-Mo area, I will have to call and cancel my 'yet-to-be-activated' plan, which also required a $50 deposit. By utilizing T-Mo's "buyer's remorse", I will be able to keep the phone, since I bought it outright, but will be refunded my $50 deposit for the service, without ever having to activate it on T-Mo's network. From there, I will pop in my AT&T SIM card, and be on my way! The only thing I'll be out is the $10 SIM activation kit.
Also, the rep's did acknowledge that the Nexus 6 is one of the few phones they have that are already unlocked.
Please do critique this if you foresee any problems I'll have popping in my AT&T SIM and using my existing service with them.
EDIT: Yargh. T-Mo had zero 64GB phones, and have since called me back to tell me they are on back order. But hey... at least I have an order in now. Beats what I've accomplished so far on the Play store all to hell.

As far as I'm aware, Verizon comes under the same category. You should only be able to activate on Verizon if you buy the phone from Google Play or from Verizon.

I bought my device from T-Mobile, removed the T-Mobile sim it came with, put my Verizon sim card in, and it worked no problem. This happened with my phone on ATT as well. The guy next to me did the SAME EXACT THING on Sprint.
I am not BSing you guys in the least. I have no problem helping out in anyway I can. I'll even give you the number and the guy at the T Mobile store who watched us do it lol.

This is incorrect, it has been working for 3 years now. Data while on a phone call has been working since LTE came out. It worked on my Note 2, Note 3, and currently works on my Galaxy S5. Also works on my families HTC M7 and M8.
However, it no longer works on the Droid Turbo, and now I believe the N6.
But the original assumption was incorrect, data + voice has been working for years. They did something now that it is not working on new devices coming out.

VZW CDMA Compatability?

All,
It seems that the only way to get the XPE working on the Verizon network is to use an already activated SIM.
If I'm not mistaken, this is only for the LTE portion of the radio (since LTE is a GSM derivation).
To activate a phone on the CDMA network, I believe its IMEI has to be whitelisted.
So, my question is, can this phone use Verizon's CDMA network?
This is important because, while I do get some LTE service at work, the CDMA repeater network typically picks up my phone so that I can receive calls.
Thanks!
CDMA works fine. I don't get LTE at home, and my MXP works fine there.

Easiest way definetly is sim swap. That being said. Being that i wanted a fresh sim. Went to store. Official vzw. All that needs to be done
If you don't have a activated nano or want to cut your micro. Go to store and let them know you wish to activate new MXP. Have them call level 2 tech and they can take care of it pretty quickly. Activated in hand. Or call #202 and explain samething and they will send it. Either way mine is activated and everything works great.

I ran into trouble with Verizon activating my device. Apparently the IMEI wasn't white listed yet.
What I had them do is use and already activated S6 on my account (wifes device). To issue a nano sim. Then plugged into my device and that got it working.
Really not impressed with Verizon not having the devices white listed already. Not sure if it's because mine is custom (64gb/ leather). Either way, I'm activated.

I had LTE once I got a nano sim. They couldn't issue me a nano sim. I'm coming from a galaxy s4 so needed to get a nano sim. Took almost 1.5 hours, but this was the employee calling someone and trying to find a way for a while. Then after all that I suggested using wifes device imei (which is on same account and takes nano sim). Which that process took maybe 10min tops and plugged the nano sim in and worked instantly. On my account shows my device as "non Verizon device". Didn't even know it is the moto x pure

They used her devices imei to issue me a sim. They can't just give you a sim. Need an imei to assign it. They won't do a random imei or one off another account. Then they used a sim that was assigned the imei of my wife's device. Then the sim updated itself with my devices imei and everything.

Will this phone work on Verizon?

If you use this phone on Verizon, does it work properly? Did you need to do anything to the phone to make it work? Total noob here. Thanks for your help!
Sorry to post twice... The model I'm looking to use on Verizon is the 128GB global version.
I know Verizon can be a difficult carrier in terms of compatibility, so I thought it was worth asking. Thanks!

As long as the phone has proper band support and is unlocked, you can pop in your SIM card and be good to go. I checked the phone on the willmyphonework website, and it has all the bands for full Verizon support. So the global version will definitely work on Verizon. You just most likely won't have VoLTE or HD Voice calls.
Yes it works fine, including HD calls/VoLTE as long as VoLTE is configured properly in your Verizon account (this might occur automatically but I'm not sure).
1X and EvDO also work great and reception is very good.
I've attached a screenshot below with a Verizon prepaid SIM installed and VoLTE active in settings.
I don't think Verizon would activate a SIM with the Mi Note 2's IMEI(s) though...so you'll almost surely need a pre-activated SIM from a different Verizon-approved device.

do i just put my sim card on this phone

So i currently have an iphone xr on at&t and personally dont like this, so i will be buying this op6t soon. My question is can i just transfer the sim card and set up apn and thats it or do i need to take the phone to at&t to activate it ?

You might wanna give this thread a look,I'm sure someone on AT&T will be glad to assist you.
https://forum.xda-developers.com/oneplus-6t/help/att-verizon-volte-vowifi-calling-t3860031
If nothing else,it's a good read,as making sure the OP6T is a good choice & all the AT&T functions you want/need will work (WI-FI Calling/VoLTE/VVM,etc....).
Typically,you shouldn't have to do a thing as far as setting the APN.
However,I'm not sure about VoLTE/VVM/WI-FI Calling working,or,if it does,requires any account adjustments/account settings changes/etc..... by AT&T Customer Care.
I have cricket (owned and operated by at&t) and as far as I know service is basically the same. All I had to do was insert the Sim from my old phone and after about a minute everything was working.
I have AT&T and when my 6T arrived I inserted my sim and received service with no issues. For lack of a better phrase it should be plug and play. I did not have AT&T for anything.

That's what I figured, judging by the short time I used AT&T Prepaid a few years back.
What sux is, at least browsing their site as a non-customer, they (AT&T) aren't exactly clear on that.
They try to make it sound as if you need to order (buy) a new SIM Card to use in a different phone, whether it's one of theirs or, a BYOD.
Is Wi-Fi Calling/VoLTE/VVM working on your OP6T w/AT&T?

Nope. They don't allow it on unlocked devices except iPhones and a small selection of Android devices. I have tried a few of the suggestions in various forum posts but none work. It's not a big deal to me because I've always had unlocked devices since I switched to AT&T and I live in an area with for reception so I'm not really missing anything that I rely on.

You might wanna give this thread a look,I'm sure someone on AT&T will be glad to assist you.

Google Fi Carrier Switching?

I'm curious, I'm VERY new to the android world (My iPhone XS Max is still my primary)
I started with Androids about a year ago out of both boredom and a desire to learn.
So, I picked up a Pixel 2, then an LG V30, then S8, then S9, until I found the OnePlus 6. I was instantly hooked on the OnePlus 6, only replacing it with the 6T for the fingerprint reader in the screen. (I still have the 6 and 6T, all others were sold)
Anyway - Google Fi is intriguing to me, as I end up in areas were T-Mobile simply doesn't work. I would like the carrier switching, but I don't have a desire to switch back to a more expensive Pixel 3 XL, that really ONLY offers me the advantage of the carrier switching. Overall, I found the OnePlus 6/6T running Pie to be the cleanest experience.
So, my question - Does anyone feel that someone may be able to get the OnePlus phones to do the carrier switching? Or is this actually a hardware feature? I know nothing about how Fi works, so please excuse my ignorance.
Thank you in advance for any productive responses.
Alternatively, maybe I should just sell the 6 and 6T and pickup with 3XL?

I believe that automatic carrier switching is an integral part of Google Fi

Oops wrong. Only for fully supported phones.

Yes, I understand that. But the question was "Does anyone feel that someone may be able to get the OnePlus phones to do the carrier switching? Or is this actually a hardware feature?"
In other words, if the switching software based that may be able to be patched into the 6/6T, or is it a modem hardware feature exclusive to the official Fi devices?

I was hopping this would be fully functional as Fi announced support for non Fi devices, but apparently network swapping is not going to work or work so well. See the write up for the explanation.
https://www.xda-developers.com/project-fi-samsung-oneplus-lg-moto-iphones/
looks to me like the one plus 6 is on there, so, the T might work as well.
contact google directly, and ask them, thats the best way to find out
Ugh, is no one actually reading the question?
I'm not asking if the phone will work with Fi, I'm asking if the carrier switching is does in hardware or software, and if it is software do the devs here feel that they may be able to port the carrier switching to the other supported phones?
ok, now I understand..
asking questions here makes people assume you are discussing the 6T, NOT project fi/android in general..
good luck

Everything I read is that you would only be using T-Mobile. But since the 6t is dual SIM you can have dual service. I plan on getting a one plus 6t and using fi(TMO) for phone calls and texting and Unreal mobile (ATT) for Data. I am not sure if you can use VZW or Sprint for the second SIM but T-Mobile and AT&T is better in most cases than TMO and Sprint (no US Cellular in my area)

Alternatively you can get a pixel 2 or 3 and project fi esim and an alternate SIM. Although it's only one SIM at a time. That way though you do get essentially 3 carriers to choose from for service
So I found if I could dial a code in my dialer for fi, with the Google Fi app installed and activated, and get "cannot switch carrier", all I had to do was clear data on my app and the dialer switch would work
It's on their site. When you choose the 6t it shows what's supported and what's not. See attached image
To answer your question, yes it appears to be a hardware problem. It is either that we don't have the cdma radios needed for sprint or el goog is playing favorites and only wants certain hardware to work for carrier switching between tmobile and sprint. I am not familiar with the us cellular required radios but it is likely the same el goog restriction in this case as well. My vote is that el goog is trying to get people to buy the officially supported devices for full functionality, they are becoming more and more just like all other carriers now, huh?
Either way I think I am switching back to fi now that the 6t is at least officially compatible for use on tmobile and I am almost certain that wifi calling will work where service is poor. I am on tmobile now and wifi calling works just fine, I made a 30 minute wifi call last night and worked perfectly.
So it's a software problem. Google will not release the software as part of an update included with every android release or they won't work with the manufacturer to update the partition responsible

OnePlus 6T has full support for T-Mobile, AT&T, Verizon, and US Cellular. For Verizon and US Cellular, it also supports every CDMA Band.
For Sprint, it has every LTE Band and is missing one CDMA Band. Sprint doesn't allow unapproved devices on their network, and activation is tied to the device MEID unlike Verizon. There's no hardware reason why Fi can't allow at least LTE on both T-Mobile and Sprint. Perhaps the issue is that Sprint restricts them in some manner from using Fi on devices not in Sprint's database. Also Band 71 (T-Mobile) oddly doesn't work on Google Fi, so maybe it would lend credence to there being weird LTE Band restrictions for Fi's carrier agreements.
Well I am going back to tmobile, fi doesn't allow wifi calling and tmobile does so for me it is a no brainer. I still think that there is more going on here than just hardware issues but that's just my opinion. I mean, why is wifi calling not allowed on fi(tmobile) but it is on tmobile?
Not sure if you already switched back or if you are open to trying another service again, but i have been using Mint Mobile for a while now and love it. My monthly payment comes out to $24/Month with 5GB of data and an additional $10/1GB or $20/3GB.
Maybe https://play.google.com/store/apps/details?id=com.cheekydevs.fiswitch can help for OP users?

Does wifi-calling work with Mint Mobile??
Eta: Checked website and wifi calling is included, and 20 buck sale right now for 3 months 8gb a month...not bad for a test drive! I'm back on fi so I can pause it while I give it a go :

Awesome dude! It is definitely worth it considering you save at least $40 from any other major carrier. Only thing it doesn't have is the visual voicemail but i never use it anyway so it doesnt bother me.
Hope it is as good for you as it has been for me.

Visual voicemail is working for me with pixel experience ROM on project fi which shouldn't work on OnePlus 6T if I remember correctly.
You try that ROM yet with mint mobile?
