Hello, a quick question.
I am trying to enable volte on Proximus, a Belgian network. I installed a rom that supports VOLTE, Alexndr's rom with PHN CSC.
But I don't see the volte option in Network Additional Settings. Am i missing something? Is there a way to force activate it?
Also, my provider says that they have enabled it only for the s7 for the moment. How can a network recognise a phone type? Via IMEI? And how can I make my phone pass from a g935f?
Thanks!
Many providers aren’t enabling advanced LTE options on older devices due to the hardware they use vs the stuff in the newer phones (such as the S7). That’s one of the downfalls of LTE (Long Term Evolution) or any aging cell technology really. If your Belgian carrier is only supporting the transceiver tech on the S7 and beyond, then youre kinda boned unless they dump a ton of money into upgrading their towers. We have the same issue here in the states with some carriers. Sounds like youre out of luck.
And yes, that’s even if your ROM supports VOLTE since the issue is hardware related
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.
I posted this ? on reddit as well; however, this device is on its last legs so there's not much interest for it. I've gotten some good answers here and there on this website, but a dedicated thread to gather all the good info might be more helpful.
I still use my AT&T H910 as I don't really do much gaming on it. Calling, texting, and YouTube is what I mostly utilize it for. I just heard about the whole VoLTE requirement on specific devices after 2022 for AT&T, and 2021 for T-Mobile.
I spoke to AT&T, and they re-assured that the H910 was going to be one of the devices supported after 2022; however, I've been thinking about changing to T-Mobile (my family has a great plan with them, and I always switch back and forth between carriers based on who gives me the best deal) but I can't seem to get a straight answer from T-Mobile about whether my unlocked H910 will work with them after 2021; some didn't even know about the 2021 specifics of it.
I know AT&T will have to allow devices to be used on their network after 2022 even if they're VoLTE capable already. By the looks of it, T-Mobile won't go to that extreme; however, does anyone know exactly how VoLTE works? Specially in regards to using the AT&T H910 model on T-Mobile? Does my H910 has the required Bands to utilize VoLTE on T-Mobile? Or is it one of those things like "Wi-Fi Calling" where T-Mobile Wi-Fi calling only works with the LG V20 model from T-Mobile, and AT&T Wi-Fi calling only works with the LG V20 model from AT&T?
You need band 12 support which H910 has. Also a rom with IMS services working so no AOSP roms.
Volte works by using IMS processes in the rom to route phone calls over IP. No volte = no phone calls. But the device will still "work".
In theory the ATT software will work, unlock it and borrow someone else's sim. In theory a partial cross flash (just system, no modem/aboot/etc) could work if it doesn't.

I was recommended to use an app called Network Mode Universal on reddit for VoLTE testing purposes, and after inserting a T-Mobile SIM card that I borrowed on my unlocked H910 and using the application, the Voice Network Type tab says "LTE". Which is supposed to be a sign that VoLTE might be working on the H910 using a T-Mobile SIM, but that's all I know; just what people tell me.
Update:
The person who recommended that Network Mode Universal app forgot to mention that you have to actually make a call to know whether the phone supports VoLTE with the SIM card in use. When actually making a call, the Voice Network Type tab changes from "LTE" to "UMTS". Which means the H910 is not VoLTE capable on T-Mobile.

Could also be how his sim is set up. Volte has to be enabled there and in the phone. My suggestion would be to force LTE only on the device as well. Does it use VOLTE on his phone?
Also look at IMS registration in the phone and see if it's registered.

The person I borrowed the T-Mobile SIM from uses an iPhone on iOS 13. According to him, the option for turning on/off VoLTE from the settings is gone. He used to be able to turn it on and off at will; not anymore after iOS 13. It should be enabled by default on an iPhone though, I don't see why it would be off. It's almost a necessity on an iPhone I would think.
The LG V20 seems to be more limited in that sense, as on my previous Samsung phone I could enable 2G, 4G, LTE, etc, individually to force only one. I don't see any of those settings on my H910. I don't see any IMS info either.
Either way, I doubt T-Mobile would bother servicing my AT&T branded H910 phone in case IMS needed to be registered; in the case that it wasn't already. I've had really bad luck in the past dealing with T-Mobile on phones that are not T-Mobile branded.

IMS has a phone component and a sim component.
you can check status in the service menu of IMS on the H910. Hope it works on my Tmo phone, getting my sim upgraded

It should work if it's a T-Mobile phone. The H918 is 40% more expensive, so it would be great if the H910 worked with T-Mobile; however, it's not looking good.

Eh, kinda. I'm having trouble too. My IMS services aren't connecting. Going to try a few different roms. I'm through an MVNO so still trying to get them to understand ISIM vs USIM.

Gotcha, I hope it works. I was mentioning to @C D which has helped me understand a lot about VoLTE, that I'm starting to give in to the system of using whatever carrier my phone supports, as long as I can keep using my H910. The removable battery & IR blaster era has come to an end, and I don't think I need another phone right now other than the V20. I might even consider going back to the AT&T MVNO I was using before.

Latest result: oreo works but not nougat.
IMS never registers. Maybe I can fix it. At least now OK sim-wise. Unfortunately doing the sim swap broke tethering.
Hi guys, I am sorry for reviving the old thread.
I too owned H990DS Sea version on latest nougat. It has volte option but just couldn't switch on.
Please take a look at this thread on LG G8
https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/
I tried on my H990DS using the above thread's method and it didn't work. I was informed that the mbn files are for LG G8. We need mbn files that are specific for LG V20. I have searched up and down and I couldn't find any.
So I hope that I have provided some insights and I hope any member/master/guru out there can help where to find the mbn file (collection of all international carriers mbn) and make volte works for H990DS.
