Has anybody tried the G950FD on T-Mobile and AT&T in the US? Ideally Tmo on SIM1 and ATT on sim2.
I know the S7 couldn't switch well between the two networks as a dual sim phone.
Also is WiFi calling working? B12? Is SIM2 3G on AT&T or still just 2G?
Thanks!

I've done some more searching so let me clean this up for future searchers...
Q1. At&t will not work well on SIM2 since they killed their 2g network. There does seem to be a 3g antenna in SIM2, but for some reason still requires a 2G network. Tmo works fine in SIM2.
2) Tmo WiFi calling is not working. Though there is hope that this will work in the future (with root). Not much hope for a native solution.
3). Volte (b12) does seem to work with certain country modems. But as of today, its not clear which countries.

thanks for info
I have international S8 SM-G950F.
Recently, I switched to Ultra Mobile and contacted them about using VOLTE because they advertised it.
Ultra Mobile is a MVNO of T-Mobile. The reason I contacted them is because you need to have a SIM that is provisioned for WiFi Calling before it will work. I tested this by going into Connections, then Data Usage, and finally Mobile data. (Turn switch off and then try using the phone or sending MMS. Mine worked. But remember I contacted the carrier after they advertised that they have WiFi Calling....
I have an unlocked Galaxy S7 Edge (SM-G935U). My carrier is Total Wireless (Verizon MVNO). I recently got a new office at work, and the Verizon coverage in this part of the building is terrible. I use wifi for data but cellular calling basically doesn't work at all.
I've been looking at other networks, and I'm leaning toward T-Mobile or MetroPCS, one of the reasons being they have wifi calling and the wifi at my office is plenty fast. I checked in settings to see the wifi calling option, but when I go to settings > connections > more connection settings, which is where the wifi calling setting is supposed to be, there's nothing about wifi calling.
I had a thought that maybe the wifi calling option isn't there because my current carrier doesn't support wifi calling, so I contacted Samsung support. I asked if I get a SIM from a carrier that supports wifi calling, would the wifi calling option be enabled. They said that unlocked phones don't support wifi calling at all.
This confuses me, because this thread mentions some people were able to use T-Mobile wifi calling on an unlocked S7/S7Edge. But that thread is older, so maybe for some reason wifi calling was removed from the unlocked S7 Edge with the Nougat update?
I suppose the only way to find out for sure is to get a T-Mobile or MetroPCS SIM and see what happens. But is anyone able to shed some light on if this is even worth trying? I suppose it's also worth trying out just to see if regular cellular calling on T-Mobile might be fine at my new desk, but hopefully there's some way to do wifi calling.
Unfortunately I think you need the sm-g935f to get t mobile wifi calling. Don't think it was ever achieved on the U models
I had an s7 edge from T-Mobile (SM-G935T) but I flashed the unlocked firmware essentially making it a SM-G935U and I had VoLTE and Wifi calling working with no issues. It was about a month ago, so it was on Nougat. I would expect no issues with an actual SM-G935U on T-Mobile.
Well, I answered my own question. I switched over to the T-Mobile 10 GB $50/month prepaid plan and when I changed SIMs the phone gave me a "reconfiguring your device for new SIM card" message. Wifi calling is now active.
Also, this is a list of phones that support T-Mobile wifi calling. I probably should've checked here first.

Hi all. Posting this for users looking for answers on VoLTE and WoWifi on the 6T on AT&T & Verizon. If users with access to the OP6T could please test and report, that would be very helpful. Since the pixel 3 now supports both VoLTE & VoWiFi (on AT&T) there is perhaps some hope that OnePlus will also support it.
1: On AT&T, is there an option for Voice over LTE and Wifi calling and does it work?
2: On Verizon, I know Voice over LTE will work, but what about Wifi Calling?
Screen shots welcome I will have my hands on the device as soon as its available and will report since I have all the carriers, but thought maybe someone might get their hands on one early and could report. It might make a big difference on whether or now some users buy the device.! Thanks guys!
Yeah, whether or not I get the OP6T depends entirely on whether VoLTE and VoWiFi work on AT&T.
Eagerly waiting for updates!

Same here!
AT&T & Verizon VoLTE and VoWiFi calling/texting thread
Same here. I’ve got a spot in SC where I got for holidays annually where, without Wi-Fi calling, my phone is a paperweight. I’ve always wanted to try a OnePlus but if there’s no Wi-Fi calling I’ll have to pass and stick with my XS Max.
I’ve already ordered but it’ll be a quick turnaround if that doesn’t work.

This question came up in the AMA with the OP team in their community forums last week, and Pei himself said VoWifi isn't supported at the moment.
Just got my device today so update time..
1: VoLTE works on Verizon by default as soon as you pop in the SIM. All the Verizon LTE bands seem to work fine.. in this area, 2,4,13, & 66. no option in the menu for wiFi calling, even though it works fine in my pixel 3 where my verizon SIM just was.
2: Neither VoLTE or VoWiFI work on AT&T by default. No option for either in the settings at all. So no change there from OP5/5T/6 ETC. However, if you go do the dialer, dial *#800# and hit enter, select oneplus logkit, scroll down to function switch and select it, and check the box for VoLTE switch and Vowifi switch and then reboot, it puts the VOLTE setting and VoWiFI setting in for both the Verizon and AT&T SIM. and while you can enable VoWIFI on both Verizon and AT&T, it DOES NOT work on either. On AT&T however, as long as you have a VOLTE capable/recognized IMEI on your AT&T account for your line, VoLTE/HD voice work just fine.
So, while it is amazing to have, for the first time ever a DUAL SIM phone that supports both VZW & AT&T at the same time, it is a too bad that VoWiFI does not work on either, Especially now that the Pixel 3 Supports it on both carriers.

Has anyone used the dialer code *#*#4636#*#* & try to toggle VoLTE &/OR VoWI-FI ?
Thanks for the info. I'm looking to get the 6T to use on AT&T. I've never used an unlocked/non-AT&T branded phone on my line. Are there any other limitations that AT&T implements on non-AT&T branded devices? Do they throttle data speeds? Any issues with SMS/MMS working like some Verizon users are experiencing? Would I need to contact AT&T to have any special provisioning just to get it to work? I appreciate any insight on this.

I'm not on AT&T so,I'm not gonna speculate.
Perhaps someone will chime-in soon for more definitive information.
My OnePlus 6t came in today. Took sim out of my Pixel 3 XL and popped it in. Everything is working except I can't SEND text messages. I can receive them and make calls, data is fine (actually amazing 44.5 mbps d/l, which is good for around here.)
I've tried chatting with Verizon, but after I told them what device, there was a long pause and then she asked if it was an iPhone
Here are my troubleshooting steps I've followed.
-deleted app cache and storage
-reset device
-factory reset device
-cleared cache partition in recovery
Any suggestions? I put the sim back in my Pixel and all the messages came through. I've tried both slots.
Mobile network state-Connected
Service state-In service
Mobile voice network type-4g
Mobile data network types-4g
EID-unknown (??)
There is another thread discussing why a lot of people using 6T on Verizon having problem receiving SMS and MMS. Something the phone being LTE only on Verizon. Maybe you are having the same problem? Worth reading that thread.

Yes. that would be best. I didn't need to do anything with mine, it just worked. However, I do have the latest version the the Verizon SIM card. Not sure if that matters. I was using a Pixel 3 before.

I have used AT&T for years on unlocked devices. I have tested everything Data speeds are just fine. no issues there. the OP6T supports all the bands on AT&T so coverage should be just fine for you. The limits are as follows:
1: built in visual voicemail will not work, you will need to use the AT&T visual Voicemail app from the store.
2: Wifi calling/texting will not work
3: VoLTE/HD Voice will only work with the above mentioned trickery. Root is NOT needed. just the *#800# thing
the only provisioning you may need is the AT&T imei for VoLTE (Easiest to do online) after installing your AT&T SIM in the OP6T, if VoLTE doesn't work after following the instruction in this thread, log into your AT&T account and update your IMEI to one of your past AT&T phones that support VoLTE and update, reboot you OP6T and bingo, it will work. No other provisioning or limitations that I know of. And if VoLTE/HD Voice isn't important to you, you can ignore all this. Your existing AT&T SIM just needs installed in your OP6T and your good to go!

The *#800# enables all those options. But it doesn't help anything on Verizon, and on AT&T it does work for VoLTE if a VOLTE enabled IMEI is on your AT&T account, but it doesn't work for wifi calling. I wish it was just illegal for the carriers to block services just because its a non branded phone

So glad that I found this post. I am coming from an AT&T branded Galaxy S8 to my new OnePlus 6T. The above instructions worked like a charm for AT&T. I ran some tests. The OnePlus displays "HD" when I call my wife on her phone on AT&T and VoLTE shows in the status bar. When I toggle it back off I lose "HD" on the phone call screen. Also, LTE stays on during calls with VoLTE turned on and I ran a speedtest with it on and off and I definitely get 4G speed with it on and it downgrades to HSPA+ with VoLTE off and speed goes way down. Hopefully VoWIFI will be supported soon but that's not a deal breaker for me as I get great reception most of the time where I live, work and travel.

I am on att had it all working on my unlocked NOTE 8. Now I can't even get volte cause it's all grayed out.
The service providers don't want you to buy unlocked phones. They make zero on them!! So that's why they block stuff. It's an antitrust lawsuit waiting to happen!! A$$h0!€$

I've got AT&T as my primary and Verizon as #2. I just got off the phone with Verizon, told them I needed to add the CDMA Less feature to fix my texting. He checked a box on his end and I got a flood of texts in...what was even better, it was a work phone on a business account. I didn't even have to provide any real information to him and he was able to fix me up. He was aware of the issue though, he'd asked if it was a 6T from T-Mobile...so someone sent out a bulletin somewhere that he had read.
Anyway, I left Verizon to go to AT&T specifically for this plan of having one phone to cover 2 lines while one being fully functional (AT&T), so far it's been working well switching between SIMs for texting and making phone calls.
What were you specifically looking to find out?
Edit: found what you're looking for...however I'm not sure where those settings are even at.
