I've about had it with this phone internationally unlocked HTC 10 here originally had Oreo on it I downgraded back to nougat properly with the 2.51 latest firmware and now Sim is working on nougat but any AOSP ROM I use voice over LTE never works. I don't absolutely need voice over LTE to work but my phone does not always switch the connection to 4G to receive incoming calls either sometimes it would just stay on LTE and then the caller will be pushed to voicemail immediately. I can make calls from my phone fine but receiving has been a huge problem. I even tried the leedroid nougat ROM and it is doing the same thing as I thought it was an AOSP problem but that can't be the case as it possibly something with my firmware? I just want this headache to go away and receive my calls properly again! Any help will be greatly appreciated
Carrier is tmobile
So I've discovered that volte does not work with AOSP ROMs but it seems when I get a call the LTE does not go down to 4G to let the call be received is there anything I can do

Type #*#*4636*#*# and change the phone frequency to your cell phone providers.
So I have used my S20 Ultra since March this year.
I've noticed that the cellular network just "sleeps" and doesn't receive calls/SMSes after some time of phone idling/usage on WiFi.
I tried googling and found many other users reporting similar issues, noticing also that it seems majority if not all are Exynos variant users (not based in US).
Personally, this is definitely not a telco provider issue as I have had this issue on my old SIM (which was working fine on my old phone) and new SIM that I recently got after switching providers to see if the issue went away.
For me, sometimes the calls come in a few minutes late, and then the phone rings but when picking up, the call just gets stuck because the other party is no longer calling.
This is particularly noticeable as due to mostly staying home during COVID-19.
Toggling flight mode to "wake" the cellular network makes the phone be able to receive calls again.

Lucky me. Didn't have this problem on my s20+ exynos

I also have this issue (S20+ exynos, dual sim). I use wifi at home/work and I had several missed calls and delayed text messages during this time.
Now I turned on the text alerts about the missed calls. At least when my phone connects again to the network I get these notifications.
I am also having this issue. People call and it rings out at their end but not at my end. Is there any fix?
Try switching the active number to slot 2. I tried it for a couple of days and I think it was better. I have switched back to slot 1 to monitor as I just got the ATE6 update and wanna see if it changed anything.
I had this issue and figured out what was causing it. You need to disable VoLTE if you are not registered to use this service on your carrier's network.

My sim cards are already registered to use VoLTE, my carrier notified me a few months ago about it.
I tried to disable VoLTE on both sim cards. It was OK for 2 weeks until now.
I got a new missed call notification text message and after 5 minutes a message from the caller.
Now I enabled VoLTE again for one sim card. Let's see if there will be more missed calls with this setting.
Hi everyone I was using LineageOS 17.1
I have 2 sim cards: One from JIO, a 4g only carrier and another from Vi (Vodafone) which has 2G/3G/4G. I flashed Lineageos first more than a year ago and everything was fine. But sometime around april this year SMS stopped working just for the JIO sim. Calling and Data work fine. I am not sure but i think I updated(17.1 -> 17.1) before this happened. Today i finally decided to investigate this. I tried the JIO SIM on another android phone as well as an iPhone and it works fine. but on my OP3T, it refuses to receive or send SMS. The Vi SIM doesn't seem to have any issues.
Another interesting sidenote is that if i remove the sim from the iPhone and put it in the OP3T, it doesn't work until i reboot the OP3T!
I tried updating to 18.1 today. It didn't solve the Issue. So currently I am on 18.1
Can someone help me figure out what the problem is?
Greetings,
I have got a Pixel 6P device from the UK Google Store.
Since then I had to move to Hungary and started using the device with local carrier T-mobile (Telekom Hungary) and using physical and esim also.
Both of the SIM cards has connectivity issues. The signal suddenly drops to zero, and I only get a carrier notification SMS for a missed call.
My network signal usually really bad. I also tried using 5G near a 5G tower but it just won't connect.
I tried to connect to VoLTE or Vowifi but both of them is disabled on the phone. However the carrier has enabled it for both SIM card and I have got the confirmation messages of it.
I tired factory reset and SIM card replecament with no luck, problem is still there. Carrier just said that that everything is fine at their side...
I have waited for the december update, and I did the update with ADB sideload.
Now the connectivity problem is still there, and I have got another big problem.
When I get a call, and pick it up I don't hear the caller and caller can't hear me neither.
If I put the phone to loud speaker and back to normal then I get voice in both sides, tried phone restart but it won't solve the issue.
Has anyone encouterd with this problems and managed to solve it?
By the way after the a December Update my battery life has been significantly better.
Thanks
