Every couple days or so, my OnePlus 7 Pro loses its connection to Verizon.
Symptoms:
- VoLTE icon missing
- Mobile data works sometimes
- No SMS / MMS
- Cannot place or receive calls
- Incoming calls ring on caller's side
- Airplane mode and off doesn't fix
- Restart doesn't fix
Only a power off and power on fixes the issue.
Note:
- Verizon added CDMA-less to my account on day 1
- Oxygen OS 9.5.11.GM21AA
- Security patch level: August 1, 2019
What should I try next?
Upon further investigation, this happens after losing cell coverage. Again, the only workaround is power off and power on.
Did you give the airplane mode some time when switching? You should wait at least 10 sec between off and on. This way you force it to reconnect.
To solve this, try a new sim card.
I also got a very strange problem when I just got the device. When VoLTE is on I could not receive calls but I could call out... This was only happening whit one sim card. Long story short, I got myself a new one and my problems where over.

- Sometimes I can make incoming and outgoing calls
- Sometimes I can make or recieve calls but the person on the other end cannot hear me
- Sometimes the person trying to call me will hear 1-2 rings and then it will go straight to voicemail
- Sometimes the person will call me but the call will disconnect after a few seconds
I'm registered on my network and have a strong signal. What could the problem be? It only happens periodically which is so strange. If it was a constant issue I could better isolate the cause but at this point I'm completely lost.
I had the same problem - go to Settings - Mobile Networks Mode - Network Mode and select LTE/CDMA instead of Automatic
Hey Guys,
Hoping you can help me. Galaxy S7 930F running custom rom:
(https://forum.xda-developers.com/galaxy-s7/development/rom-galaxy-project-t3440314)
Ran it in December v8.13 with Android 6.0.1 and was getting the follow issue:
- Inbound and Outbound Calls Unable to connect
- SMS/MMS and data over 4g/3g good.
- Different carrier sim - All ok
- Sim in different phone - All ok.
Decided to update to v9 with Android 7, on a full wipe and format and still the same issue.
APN setting are good. copied from old to new, even tempted reentering to be sure. but still the same
Under SIM status shows as connected but still unable to connect.
1. When I make an outbound call I get nothing, just the sound of attempting to call, no ring and just silence.
2. Inbound calls get a 'The mobile phone you are calling is not accepting incoming calls'.
Anybody got any suggestions? Getting really confused now.
am facing a weird issue with my pixel 2. Whenever the phone is in idle state I dont receive any calls or sms.
For e.g. if I just made a call and kept the phone down. And there was nothing that I received for next 20 to 30 mins. The phone shows its switched off. I cant receive any calls or even sms. This resolves when i restart and then work for next 30 to 60 mins and problem reappears. Really frustrating.
I tried the sim in my samsung and it works great. So defn not a provider issue. Not sure if its a volte issue as i tried using an alternate sim and network wont detect in pixel 2. The network in same as original VOLTE enabled.
I reset my phone twice also reset the network settings. Tried using the 4636 menu to change radio mode. All of it works for 5 6 hrs and the problem returns.
I spoke to the google technician he seemed helpful but asked me to try all things which I already did. Any idea what it could be?
I am on the march patch smaller pixel 2.
Odd problem I'm trying to track down.
My outgoing calls are not working right The other end hears only static or silence, but if they call me, it's perfectly ok.
I've done the following
Rebooted
Toggled Airplane Mode
Toggled Enhanced 4G LTE
Reseated my SIM
Updated my ROM (LineageOS) to the latest (was on December 18 Build, now on Jan 03 Build)
Tried from multiple miles away to attempt to use different cell towers
My phone is a Oneplus 3T, and my carrier is Cricket Wireless.

The incoming calls working fine sounds very weird indeed. Try the SIM in another phone, and a different SIM in this phone, and see what happens.

I have to see if I can find anything to test with. I've had this phone + carrier + sim combination for over two years now. This just started last night.
The fact though that no incoming calls have this issue is what's really throwing me. It makes me think the issue may be some sort of carrier issue.
I'm rooted, so if this is still happening tonight, I'll see if I can also grab a logcat from the timespan in which I place a call.
My phone updated 5 days ago to Android 11.
Its a stock rom, not rooted yet.
Ever since then my phone will not allow any calls to get through,
The phone (sometimes) rings once and the caller gets put through to answer phone.
I then get a notification to state its a missed call.
its as if its stuck in DND.
So far i have missed 17 calls.
DND is off,
I have reset the cache,
Booted in to safe mode and it still does the same,
Callers in favorites do not get though,
Callers calling back twice straight away dont get through,
All apps are updated as of this morning as well and the issue is still happening.
I have a scheduled DND on from 06:00 to 13:00 (night worker) and 22:00 to 06:00 when im not on nights,
This has worked flawlessly since i have had the phone, and also on previous phones. I also turn DND on and off as and when required.
Now the issue is it appears to be stuck in DND, by that i mean EVERY call goes straight to voice mail.
DND shown as being off, in the pull down menu and the main settings menu.
Manually DND on - 1 ring straight to voicemail Manually DND off - 1 ring straight to voicemail
Auto DND exactly the same.
I only noticed this as i was waiting for a few important calls, and when i checked the phone saw a load of missed calls.
Now i have reset the phone, tried this in various different locations so its not signal strength related,
tried it with wifi calling on and off as well.
I've also checked the following as well.
Block unknown / private calls is off.
Caller ID/spam is off.
All call alerts are on. I have multiple ringtones assigned.
Auto answer is off. wifi calling is currently on. (still issues when not connected to wifi)
Call forwarding is off
call barring is off
Call waiting is on.
Fixed dialling is off.
Phone version is 12.1.02.12
Call version is 12.0.01.30
Latest versions are installed.
Phone is correct default app.
Any one else have the same issues and managed to fix it? any ideas?
Dont want to do a full reset yet as i dont have access to back up everything.
Cheers
Mac,
