VoLTE not working in any custom ROM that SUPPORTS it. - Xiaomi Mi Max Questions & Answers

Hi, so the thing started less than about a month ago, I was using the official Xenon HD ROM and was using VoLTE just fine (Jio) but on day suddenly, VoLTE stopped working. I tried reinstalling the ROM, installing other ROMs and such stuff but had my exams so I just installed the official MIUI for the time being and VoLTE was working fine. I wanted to switch from MIUI so today I installed Resurrection Remix 5.8.5 and VoLTE didn't work. I tried installing the unofficial LineageOS 14.1 by Nijel8, VoLTE worked fine for a while, then I installed Magisk 14.0, rebooted and VoLTE stopped working yet again. I uninstalled Magisk, still no luck, then I clean flashed the same LineageOS ROM again but VoLTE remained broken.
I wanna ask, why can't I get VoLTE to work when the said ROMs have VoLTE support, with other users actually using it. Thanks, I don't wanna go bakc to MIUI

Never mind, I fixed it by adding ims in the APN type field in my APN settings as suggested by Room Danton

I have the same problem. Can you please tell me how to fix it?

could you explain yourself better, "how to" if possible? thank you

Sudden AOKP ROM problem ???

I had flashed AOKP 21/2 build. It was working great for a week with little overheat problem . Nothing serious though . But from today onwards it started restarting on its own. It happened couple of times and now all the bugs people have mentioned starting showing up. It makes that crackling sound when headphone is inserted and won't recognize it . Network won't come after the restart. That brightness fluctuation and almost everything. Does anyone has the same problem ? Cause for a week it was working great. even my video recording was fine.

Try AICP - https://forum.xda-developers.com/k5-plus/development/rom-k5-plus-t3536263
It is the most stable rom i found till now and VoLTE also works pretty well.

Why stock rom ?? VoLTE works on custom roms

The modem you have installed must have come from a stock om with volte support in order to continue to enjoy volte on your custom rom. the custom roms do not provide anny modem software and hence if your stock rom did not have volte you will not have it after flashing a custom rom.

My gps is not working. I tried flashing my room twice but still no use.

My gps is not working. Installed Resurrection remix room and then again tried with cm14.1 . But its still not working. The GPS stopped working since I started using fakegps and enabled mock gps. I already removed the app. And flashed the room twice.
Used gps status app to check and found orientation sensor is not working.
Can someone tell me if this can be solved?

Go back to stock ROM, and see if it starts to work again, then try Resurrection Remix or LOS 14.1 again.
I was having the same issue, and yes, going back to stock ROM did work for me. I HATE the last stock ROM though.. the apps, the email program is messed up.. which was what I was using, I love my rom, (slimfast 4.4) but it screwed the gps as well.
I then went back to the slimfast.. just last night.. and although the GPS is working again.. it will not LOCK.. it finds satalites and works.. but never locks.
I think it might be my kernel, but thats another thread.

Had a backup of my stock rom. Installed it. Gps worked. But wasn't accurate. Then I flashed with lineage os 14.1 and the GPS stopped working again.

Then it's a ROM issue, it's LineageOS issue not yours, you can make a bug report at Gerrit if it's official lineage, if not ask the developer to fix it and give him a logcat.
I suggest flashing a stock ROM as the stock ROM will return everything to stock, including modem software.

IMS Status : Not Registered { Volte not working }

Volte was working perfectly fine 15 days ago. Used many custom roms, worked perfectly. Suddenly, it stopped working. I tried different roms(it worked previously on these), no use. When I checked the IMS status, it says not registered. LTE is working fine , but volte doesn't. How do i get volte to work ??

Same here..!
the VoLTE was working fine with zui.. but with the custom roms in lost this feature..(using AEX and they do have VoLTE option)
i have attached a few screenshots here, Let me know if that helps someone in solving the problem..
Revert back to Stock rom!
I encountered the same problem and reverted back to stock rom.. There was a issue with baseband and it can be fixed in this way.. Now it's working fine in custom ROM too !!

Mobile Networks

Hi guys.. I unlocked the bootloader of my Z2 Plus a few days back and installed Resurrection Remix v6.0.0. The day I installed the rom, it was working great. Everything was working fine, but the next day, when I woke up and checked my phone, there was no network in either of the SIMs that I have (Jio and Airtel). Since then, I clean flashed resurrection remix several times, changed my baseband version to 1.70, but nothing worked. Is there a way to fix it?
P.S.: Both SIMs work fine as I have them installed on a different phone.
I think same question is being discussed at RR ROM thread page 49/50

maximum all ROMs have volte enabled. if you're in roaming then you need to set ims settings in access point. and if you're not in roaming then you need to flash volte enabler zip present for lenovo p2. just search it
Thanks I will look into that appreciate your help will update on my progress
4G VOLTE works for me on LineageOS 15.1.

Which RR ROM did you install mate? I'm finding LOS 14.1 performance is sluggish and I'm experiencing kernel wakelock battery drains as well.
Keen to move to another ROM and kernel if necessary.
