No mobile data while making a phone call?

Both mine and my wife's 6p's are not able to access the internet while a call is in progress. My phone is unlocked & rooted, however my wife's is complete stock so I know that can't be the issue. I've also tried disabling the "enhanced" calling with LTE under cellular networks on both devices and this doesn't fix the issue, either. We're on Verizon, for what it's worth. Is anyone else experiencing this? If so what carrier are you on? Thanks!
EDIT: Fixed it for anyone else who comes across a similar issue: after going into my Verizon online and adding the Advanced calling 1.0 feature to my line, then rebooting my phone, and waiting a few minutes, things automagically started working.

Just bumping because I had the same issue and this fixed it.
Thanks

Hi, I'm having the same issue with a stock Nexus 6P on Verizon. However, I can't find Advanced Calling 1.0 anywhere. I found 'HD Voice' on Verizon and added it to my plan, and made sure the 'Enhanced 4G LTE Mode' is on and it still doesn't work. I've rebooted many times, no luck. Any ideas? I read somewhere that it may depend on what kind of tower you are on, does anyone have any more information about that or what I can do to make this work? I also still have unlimited data and I use my hotspot all the time, so this is a real problem. Thanks!

I am bumping this thread. I have unlimited data under the Verizon grandfathered plan. Does turning this feature on count as a change to my account and possibly mess with my unlimited data status?

Anyone else with a similar problem? I am also using an unlimited data plan under Verizon. I have the feature turned on and still have data dropout every time I am on a call. This has been present ever since the 6.0.1 update for me.....

Sim card disappears after 2-4 minutes when making calls with VoLTE enabled

My v20 drops all calls between 2 and 4 minutes in, and usually around the 3 minute mark. The call drops, signal goes to zero, and a moment later I get a toast message saying "Loading SIM card contacts..." and then I can immediately dial back in.
WiFi calling is disabled, though the setting being on or off doesn't seem to make a difference. I've cleaned the SIM card and added tape to the back to ensure good connectivity - no change. I also went to T-Mobile and they replaced my SIM on the spot but it immediately happened again in the store and in front of the clerk when we tried a call. They've suggested a warranty exchange.
One interesting thing I've found though is that disabling VoLTE calling fixes it entirely - it no longer drops calls, but of course there's no HD voice and I can't use band 12 and they're already cutting back on HSPA coverage.
Haven't found anything else useful via Google or XDA. Even with VoLTE enabled there are no data drops, VOIP calling via hangouts works fine. Anyone have any ideas short of a full exchange? Not rooted and while the LG backup app is pretty good, I really don't want to go through the day-long process of restoring everything if I can avoid it.

Hey there! I had the same issue, exchanged the phone for a new one, and STILL have the same isssue! Did you ever find another fix? This is so annoying and I cant believe a bigger deal isn't being made of it.

Something wrong with ur

Been owning V20 for about 5 weeks now. The first 3 weeks were pleasant until I started seeing dropped calls. Disabling VoLTE did not help. Changing sim card wouldn't help either.

I'm having similar issues H915 Freedom Mobile.
Was roaming on AT&T in the US when I first did the update. And everything was fine till I was home and on Freedom.
When Wi-Fi calling is enabled. It makes no difference if mobile preferred or VoWIFI preferred is selected. It enables either way after reboot or turning Wi-Fi adapter off and on again.
Incomming calls frequently don't come through regardless of whether vo wifi is on or off. Texts same problem. And persists sometimes on cellular and sometimes on VoWifi.
Get SIM errors, signal drop constantly. And have tried everything I can think of to rectify the issues with zero success.
Anyone with Freedom having similar issues? Or any suggestions I might not have thought of that may be the the cause?

G6 delayed calls/sms

I'm hoping this is the right place to ask, haven't posted here before, but I'm stumped. I recently upgraded to the LG G6, it's on Bell in Canada. Loving the phone, but having one big issue. When I'm connected to WiFi, I miss calls and texts, it's not consistent but often enough that it's a problem. As soon as I disconnect from WiFi I get any delayed texts and voicemail notifications for any calls I had missed. I'm just running stock, and these are the steps I've tried so far:
-changed sim, nope
-factory reset, nope
-tried sim in another new G6, nope
-turned off VoLTE in call settings, nope
-cannot find a WiFi calling setting or would have disabled as well
-checked with Bell and LG and both say they're unaware of any related issues and advised wait for patch.
Anyone have any other suggestions that may help? I really like the phone, not a Samsung fan and I'll wait for updates if need be, but maybe it's a quick fix in the settings somewhere. *fingers crossed*
Thanks!

WiFi calling setting is in the call option inside your system settings.
Could be your WiFi/router isn't good enough to handle that.

Sounds like a port forwarding issue quite honestly. Probably a Wi-Fi router issue more than the phone issue.

I don't have a WiFi calling option in my call settings, it should be directly under the volte toggle I thought, but can't find it anywhere. And happens on multiple WiFi networks. My home network itself is getting about 50mps download speed when I run speed test on my phone on WiFi.

That's very strange that you don't have a WiFi calling option. Is WiFi calling a region specific feature as well??

If I'm not mistaken, I think it's carrier and device specific. I checked through my Bell plan and I don't see it listed as a feature, but I know the G6 supports it. But I checked everywhere and can't find anything pertaining to it. Odd.

Maybe that is the issue. Perhaps the LG Software is trying to accept calls and texts through the WiFi signal but something that your carrier has done with the blocking off WiFi calling on their end is causing the bug. I'm not too savy with the way Android and it's coding works.

VoWiFi is carrier specific feature. though LG G6 supports it , carrier can disable the feature as you bought phone from him. you can go to hidden menu (277634#*# or *#546368#*872# , here 872 is the phone model , replace it with yours) and turn off VoWiFi.

Wifi calling - inconsistent with 8.1 Oreo - T-Mobile

I'm finding that WiFi calling stops working randomly. A reboot gets it to work properly again. I have my advanced call settings on Global and Wifi Preferred as my option.
Anyone else having this issue with Oreo 8.1 and T-Mobile?

I've had this issue since I upgraded to 8.1. I've been planning on doing a factory reset to see if it fixes the problem, but I really don't want to go through the hassle of setting everything up again.
I have no cell signal at my desk at work, so I use the WiFi calling often. However, I have noticed something rather strange. If I try to make a call or send a text, it will sometimes say something like "No WiFi network available". There have been a few times after it has done this that I have received a call on WiFi, and then it will work fine for a while. Otherwise, a restart fixes it.

Another thing that I noticed is that when on Wi-Fi calling, sometimes the phone will only ring once before a call goes to voicemail. Seems like there may be a delay in the call coming through. I generally have a good Wi-Fi connection, but like any Wi-Fi connection, it can come in and out occasionally.
I want to avoid a factory data reset as well.

I have the same problem Essential on Sprint

I am also experiencing this since the 8.1 upgrade, 8n T-mobile. Multiple networks that had WiFi calling pre-update are no longer functioning on either of our phones(wife and I both have them). I often work in a basement, so this is an important function for me.

Anyone else having issues with MMS on T-Mobile (international version)?

I ordered my OP8P directly from OnePlus, but my MMS doesn't seem to be working. Anyone else had the issue?
I actually got a message that the settings were not correct, and that the correct ones were being sent to my phone (had never seen that before). I looked at the APN info, and it seems to be correct... based on memory.

I'm on T-MOBILE also and received the same message. The phone had an update so I installed and rebooted the phone. All call,text, MMS, data worked like it's supposed to. Try rebooting?

I have issues when connected to WiFi, message comes in but doesn't download

I've tried rebooting. Things are a lot better, but I still have some issues with calling out (can't remember the message... will try and get a screenshot next time). If I immediately try again, the call will go out.
I'm also not seeing any wifi calling. The feature is enabled, but it doesn't seem to be working... even on the "wifi calling preferred" setting.

Just wanted to post an update.... still having issues. MMS pretty much never works with wifi on. For this reason, my wifi is off pretty much all day. It never fails that as soon as I turn it on, a picture or group message comes in.
Also, this does not affect SMS or RCS messages, which appear to come in over data somehow.... just MMS.
Need a fix bad.

I'm having the same issues with T-Mobile. I'm leaving wifi off in the meantime. Hope there is a fix soon.

That was supposedly fixed with the last update. What software version are you on?

Hi, not sure if it would make a difference but I'm using Google messages with the chat features enabled. I never noticed anything unusual though but I live in Louisiana. Sorry to hear that. I know there is an option for mobile and wifi (dual-channel network optimization) that I haven't been using. Anyway I hope this clears up for y'all.

I'm on 10.5.6. I just went to t mobile and got a new sim card.. It didn't resolve the issue.

Use Textra app, go into settings for Textra and it has option for TMobile WiFi, works great

You really, REALLY had my hopes up. It actually makes sense, but it doesn't work. I tried with both on and off... no luck. MMS messages (both inbound and outbound) are stuck until I turn off wifi.

I used to use the Textra app, but really prefer Google Messages for it's web app. I am on the PC all day, so it's aggravating to have to pick up the phone all the time. I've tried MS Your Phone, but it's not as easy to use, or as reliable.

I created a thread with a similar (but opposite) issue to what you're experiencing. A friend of mine with an international 8 Pro on TMO is having the exact issue you are.
https://forum.xda-developers.com/oneplus-8-pro/help/receive-mms-wifi-calling-tmobile-t4088673
Didn't get any help from that but you can try the APN trick for a temporary fix until it's patched for real. I also created a thread on Reddit for this and I think I found the solution. I use Textra, but that alone didn't help. Someone on Reddit told me to disable the stock messaging app, as well as revoke it's permissions to everything. Since doing that I'm no longer having issues. It's only been about a day so we'll see how it goes from here.
Hope I could help!

Duplicating the APN worked (of course, I did the whole thing then swiped back, thinking it would save, grr). I'm guessing it won't last long. It's just as easy to disable wifi for it to send... so weird that you're having the opposite problem.
**EDIT**
Nevermind... it didn't work. I was able to send out with wifi on (which I couldn't do before), but my wife's test message wouldn't download until I disabled wifi.
I had frozen the stock messaging app on day one, with tibu. I thawed it, revoked the permissions, and disabled it via settings this time. No luck "Not sent. Tap to try again".

Anyone find a fix for it yet? I thought 10.5.8 would help but I still can't receive or send MMS on WiFi.

Granted, I haven't done any extended testing yet, but I can send/receive MMS now with wifi connected. I upgraded about 4 hours ago, and this is probably the longest I've ever had wifi on.
Now that you've posted this, I'm skeptical it will last, though.
**EDIT**
Yep. MMS is still broken when on wifi. Geez....

The latest update seems to have fixed it for me. I was also having issues receiving calls. Callers would get a busy signal. The update fixed that as well. Maybe try taking your SIM out, reboot, then put it back in and reboot.

That didn't work. I'm finally getting notifications from my sports app after the 10.5.8 update. Just have to fix the wifi now.

Wifi still dies on me, but not with the ! on the icon. Just no traffic. I had to toggle it. But nowhere near as much as it used to. The MMS issue is the only reason I don't leave wifi on. I was really hoping it was fixed.

Same issue here even with most recent updates. MMS will work 1/10 times over wifi (sending & receiving) but not the other 9 times.
Since the update I've also noticed wifi issues - they may have been there before but didn't notice. Wifi seems to hang, I sometimes see a "!" next to the wifi symbol. In many cases I turn WiFi off and the connectivity issue in whichever app is resolved.
So at this point on TMobile there is no reason to keep wifi on, which is unfortunate because with their "5G" I actually get half the speeds of LTE. ?

Pretty much everything you said. I'm really upset and disappointed. I'm actually considering returning the phone and going back to the OP7P. Not even sure what the return policy with them is...
