Dual SIM Verizon Wifi calling help - OnePlus 7 Pro Questions & Answers

Hey all,
Sorry if this is a duplicate post, I tried searching the form and following a couple of instructions to no avail.
I have a dual SIM 7 Pro with T-Mobile and Verizon. I have already added the 7 Pro to my Verizon account and everything seems to be working.
The only problem I have is that under SIM settings for my Verizon SIM, the option for Wifi calling is there, but it won't let me turn it on. When I select to have it call over wifi or won't let me change it.
I'm not sure if I'm doing something wrong, or if there might be a tutorial I can follow to get it working correctly.
Thanks all!

If I recall, wifi-calling only works on verizon branded devices.

[Completed] Simultaneous voice and data on verizon Note 5

I searched this but was unable to find any matching scenario. This is typical CDMA carrier's simultaneous voice and data issue. The phone (Galaxy Note 5) was bough from Verizon and gets 4glte fine when on Verizon SIM card... even simultaneously. I wanted to use the phone with a AT&T sim and after changing APN settings it does work fine, but NO simultaneous voice and data. When I make a call the 4glte signal on the top status bar changes to 1x and there is no data. Once the call ends it switches to 4glte. I have activated Advanced calling with Ver sim card on and when the ATT sim is in it does show HD calling enabled. So what's wrong with the device?? Did anyone face same issue ? Any suggestion will be greatly APPRECIATED. btw I am w/o any contract plan with Verizon

Volte how-to ?

So I call up my carrier and ask them to activate Volte on my sim number. Carrier verified that it's activated within 30 mins and once I switch it on in my phones menu it'll work.
Restarted phone but no change in the settings? No Volte option..
Searched a lil and found some mixed answers between flashing AL-00 and the US version to get the menu to show up.
I even installed shortcut master to get to the hidden sub menu but all I was able to find was wifi calling, no Volte..
Anyone in my situation that was able to get it to work? A friend of mine went as far as updating to a new sim to get Volte working on his iPhone... Could the sim be an issue? Could a software update/rebrand fix it for me?
I'd like to try everything from my side before paying for a new sim with no guarantee that it'll work..
Any help is much appreciated

Oneplus 7 Pro T-Mobile (GM1915) on verizon, is VoWIFI possible?

Hello,
I recently purchased a T-Mobile unlocked Oneplus 7 pro (GM1915, 8GB ram/256GB storage) on eBay to use on Verizon, and I can't seem to get wifi calling to work. We went through the setup with Verizon, and let them know it was a CDMA-less device, and everything works perfectly besides wifi calling. I do not have the option to turn on wifi calling in the settings of the phone or the log kit. When I dial *#*#4636#*#* in the phone app to get to the phone info, the VoLTE provisioned slider is enabled and able to be turned on and off, but the Video Calling, Wifi Calling, and EAB/Presence Provisioned sliders are all greyed out and disabled. I called Verizon to check on their end if it could be enabled, and he said it was enabled on my account, but it still wasn't working on my phone. He put in a ticket to verify the E911 address, but after reading a lot of threads on forcing VoWIFI on other models, I just wanted to see if it was even possible, as I saw next to no threads on my specific model of 7 pro. If anyone has any guidance for me on this issue, I would really appreciate some help.
Thank you!
Won't work. The phone is not a Verizon phone and will be refused access to the vowifi server. Only the pixel ever functioned. Sms over WiFi will work with the Verizon messages app or Google messages and rcs. You best option is Google voice for vowifi.
Welcome to Verizon where unlocked 5g phones don't work on 5g either.

How To Guide ASUS ROG Phone 5 working on Verizon (US)

tl;dr - I was able to get my ROG phone 5 working on Verizon in the US. I thought I'd let people know of my success and give a rough guide, but won't be able to support a lot of follow-up questions. Also, if this doesn't work for you, sorry - I'd not go out and buy this phone just on the basis of this post, but just relaying my success and saying that it's confirmed possible.
Rough steps:
Get a ROG 5 from US Store. Others might work, but the model I have is ASUS_1005DC
Add HD Voice and CDMA-Less Provisioning to your account either via Customer Service or VZW Corporate store.
Get a 5G SIM from a Verizon Corporate store
Provision the 5G SIM in something that the VZW system will accept, to get it associated with your account. (iPhones work great).
Set up your ROG 5 (both in the sense of Google, and then dial *#*#3642623344#*#* from your phone app's dialer and then going into settings and turning on WiFi calling and 4G Calling.
Insert (or pop-out-and-then-back-in) your SIM card (Slot1).
Hey all -
I'm posting here (after a bunch of lurking) to let people know that I got my ROG Phone 5 working on Verizon Wireless (VZW)- as far as I can tell everything works (except for Verizon video calling, haven't tried that yet), and I don't really mind since there are significantly more common ways to get this working.
These are the steps *I* went through to get my device working. They might not all be necessary. They might not be all-inclusive. =) I also mess around a lot to get my device up and running, so it's possible I didn't document something. Anyway, enough with the disclaimers:
I bought a ROG 5 directly from this link. (I don't know if any other models work, or any CN models with flashed ROMs work.). I purchased this one because I specifically wanted the one with all the bands in the US, and the Tencent one does not appear to have as many bands - and the specifications on many of the reseller sites are unclear (and flat incorrect). Note that there are many different variants. The part number that I ordered was ZS673KS-16G256G-BK, and the part number on the sticker on the device itself is ASUS_1005DC. My current OS version is 18.0840.2104.49.
Based on poking around here and reddit, I found that people had gotten non-CDMA devices to work on Verizon by having HD Voice and CDMA-less provisioning enabled on their accounts. (OnePlus 7 Pro was the reference device I used). Note that if you do not have BOTH of these enabled, weird stuff may happen. (No phone calls can be made, texts will go into /dev/null, texts might be sent but not received.)
You need a 5G SIM card. I had a 4G one from my previous (non-CDMA device), but just physically transferring did not work. (at least some combination of 4G sim card and not having the right flags provisioning enabled on my account). I just want to a Verizon corporate store on the advice of a Cust Service rep and they were able to help me out.
You need to have them provision the 5G SIM card to a device that the Verizon system will recognize, because if you try to provision the card and tell the VZW system that it's going into the RoG phone 5 (using the IMEI), it will fail horribly. The VZW person put it into an iPhone 12, associated the SIM with my account, and then I put it into my Rog 5 (Slot 1) and both the phone and device were happy.
You need to go through the normal google setup steps, and then type *#*#3642623344#*#* into the phone app to expose the calling via 4G and wifi calling options (and video options). I don't think this survives a reboot.
Enable 4G Calling: Settings->Network & Internet -> Mobile Network -> SIM1 -> 4G Calling. (I also turned on 5G and Auto 5G here, seems to work fine)
Enable WiFi calling: Settings->Network & Internet -> Call -> Wi-Fi Calling
Pop the card into the device (or remove-and-replace) to get the device to renegotiate the settings.

Phone calls, text, work (send-and-receive via Google Messages.)
This is great news and hopefully can be confirmed by others. I'm currently on the LG V60, but with LG leaving the market, this is about the only phone of interest to me (or perhaps the ROG 6 by the time I need to upgrade?). So far, the only other info I saw on this was a Reddit post that mentioned only getting data working but no voice calls.
Has anybody else tried this?
Thank you for the steps. I finally got the phone and can confirm It is working on Verizon. For me, I just did it with my previous 4G sim with no other steps other than enable the wifi calling. (I may have done the enable HD voice to activate ROG phone 1 on Verizon as an FYI). Either way, calls and text are going through the Verizon sim just fine.
EDIT: So, the phone part works for both inbound and outbound. Text is only outbound right now for me. One question though. If I reboot the phone, then I have to reinsert the sim after it boots in order for the voLTE to work again. Does this happen to you or did it happen? If so any fix?
EDIT(Final) : Everything works fine now. Used oneplus 6t to force verizon set the line properly then popped into the phone. Just need to redo the dial code after a reboot. Thankfully just turning off the sim and turning it back on works instead of having to take out and reinserting.
This is on the ROG phone 5 Ultimate that I purchased form ASUS USA store.

It works. Got it going on my 5s
This does work and even works with the 5S and pro model. The only caveat I've found is that every couple days I won't be getting messages outside of the chat feature in Google messages. So people who don't use that or have iPhones you won't receive their messages unless you remove the sim and put it back in. Not a big deal as every couple days I like to reboot my phone and I just remove the SIM card and put it back in while I'm at it. Then I go into SIM settings and disable then re-enable 4G calling and everything works perfectly
Can confirm these steps work on the RoG Phone 5S Pro (USA model). However 5G seems to not allow incoming texts through (will test that again later) so I have 5G turned off. Sim card removal is not needed though as @TheFerret09 mentioned. I just turn on airplane mode on and off for 5 seconds and the texts will come through. Haven't rebooted in over a week now.
If you are rebooting the phone, you will need to enter the code in step 5 again and disable and reenable 4G. Removing the sim card and putting it back in does the same thing as the code I guess?

After following the steps like putting in the code and re-enabling vo 4g after a reboot, occasionally I can't get messages to come through, but removing the sim did the trick. Next time it happens I'll have to try just putting it in airplane mode to see if that does it. Would be easier for sure.
But I'll randomly just not be getting incoming messages even though the volte icon is visible (for me that means everything is working). So that's when I will remove the sim. Hopefully airplane mode helps. Thanks for the heads up.

Ya see if that does the trick. How is your experience on 5G? I dont have any actual 5G in my area, just the nationwide crap. In my initial tests, the 4G in my area seems to be faster than 5G while connected to a tower that has both.

In my area 5g blows so I don't use it. 4g is far better and faster for the time being so I haven't had a good chance to try it out.
Does anyone know the correct code for the Rog Phone 5s (1005DC)? This one *#*#3642623344#*#* isn't working. Thanks!

It will appear as if its not working when you type it in but you should get the extra options in "Network & Internet" settings to complete the process.
After weeks of trying to get Verizon to place the phone on their DMD and enable CDMA-Less on my account, they just kept saying that the Asus_1005DC is not fully compartible with their network and will not activate it. That was unfortunate and I had to return the device.

Well, you weren't supposed to specifically ask them to add this phone on their DMD. You needed to follow the directions above more carefully. You should have placed a 5G sim card in a phone already in their DMD (borrow a friends phone or use your old one) and ask them to provision it as CDMA-less. Then you would transfer the sim into the RoG Phone 5.

How was I suppose to know what phones they have on the DMD? The only other phone I had was a verizon LG V60.

I would think its pretty obvious this one would not be on their DMD otherwise this thread would have no reason to exist.
This is an update:
Got an Asus_AI2201_D ROG Phone 6 Pro and tried this guide again. Got the phone working on VZ on day one.

I'm actually seeing this issue as well on my 6D Ultimate - for a while I assumed I was typing it wrong but I've quintuple checked at this point and I never see these extra options in my Network & Internet settings. I enter the code in the phone app and it clears itself out but the settings doesn't change. I've rebooted and checked this process many times. I've tried searching for this and other people use the same code so I'm not sure what's up.
I'm probably just going to give up and switch to Mint though - I live in a city so I'm not crazy worried about losing the coverage.
Edit to add: This is with Visible (which is a fragment of Verizon and the SIM even shows "Verizon" when inserted) so maybe the options don't show up if the SIM isn't like, the "right" SIM? Only thing I can think of.
The options are there. You need to enter on SIM 1 settings.
I have since switched from the phone 5s to the Phone 6 Pro (ASUS_AI2201_F)

Question Wifi-Calling?

Greetings everyone!
Just got my Pixel 6a, love it so far, but i have one problem: Wifi Call doesnt work.
Whenever i try do a wifi call, i just get the message "out of network call"
Im using a german sim card from o2 (telefonica) and the thing is: my prior phone
was a redmi note 10 5g and with this phone (same sim card) wifi calling just worked like a charm.
so my question is: is there any trick to make it work? any explanation why it doesnt work with the 6a?
its a real bummer to go from a cheap a... redmi where this function just works fine to a nice and not so cheap pixel
(love google phones by the way, its my 3rd one), just to realize that something doesnt work as excpected.
i also tried a different os (calyx os), still no wifi-call.
help?

I'm using the Pixel 6a in Germany with o2 too - I've no issues with VoWifi and VoLTE. Are you shure you've enabled WLAN call in the accordant settings?
I use Google Voice...there an easier way w/o picking up an additional phone #?
On AT&T in the US...which is prolly why...lol

i wrote that i used wifi calling with the redmi just fine, so i guess i know how to set it up, yes. so far i tried two o2 cards, no luck. question is, can you (you) really do phone calls by wifi or are you just using cellular without actually knowing. can you still do phone calls when airplane mode is on but wifi is enabled? do you see the wifi-icon onscreen (below number/name you're calling) when making a call?

Hi,
I'm having similar issues with my Pixel 6a, also in Germany. I use it with two SIM cards (o2/Telefonica physical SIM card and Vodafone eSIM). I have enabled Wifi Calling in the SIM card settings for both SIM Cards, but _most_ of the time, it doesn't work. The phone tries to use placing calls over cellular (my home office is in my basement, so cellular reception is pretty bad to non-existent, especially with Vodafone)
Most of the times, because sometimes it does work, then it shows up in the status bar and the wifi symbol is shown when placing a call. I couldn't yet figure out any correlation to when or why it works or doesn't, I have tried restarting the phone, putting it to airplane mode, deactivating and re-activating Wifi-calling - or just using one SIM card.
I'd say ~90% of the time it doesn't work.
btw I have used a Pixel 4a with the exact same setup / SIM cards before and didn't experience any issue whatsoever.
Do you have any workaround in the meantime?
Not sure if this helps any, but when entering *#*#4636#*#* on dialpad, going into 'Phone Information'
Is WIFI Calling Provisioned enabled like in my attachment?

Thanks for your answer. It is enabled for both sim cards indeed, though (WLAN-Anrufe eingerichtet is the option in German).

Very welcome.
I'm sorry, I wish I was able to help with this!
I have found the error - it's actually caused by Blokada. I'm not sure whether it's just after some update of Blokada (I have used Blokada v5 for quite some time and regularly update) or the combination of Pixel 6a with Blokada, though. But Wifi calling always does work, when I disable Blokada.
Than I found this thread and have subsequently added com.android.phone and com.android.providers.telephony as bypass nad it does seem to work until now. Somebody else suggested bypass of Carrier provisioning service, I haven't tested yet, since as said it does seem to work now.
Just wanted to share my findings, if somebody else stumbles upon this thread.
