UPDATE AS OF 05/26:
After flashing a global or EEA firmware from here, backing up my modem in TWRP, flashing the 20.5.21 firmware, and then restoring the modem, VoLTE is now working normal, the only remaining issue is that wifi calling will only work and enable in airplane mode, whereas previously(on the global ROM) it was always enabled.
Greetings all,
I recently got a Mi Note 10 Pro as an upgrade from my Mi Max 3.
For context for my bug report, my Max 3 is running Xiaomi.eu 20.3.26, and was using the same SIM card that I'm using now.
I get good enough reception, am able to make and receive calls on both,but on the Max 3 earlier this year after switching sim cards from T-Mobile, my MMS messaging stopped working using the google messages app.
Though mms worked using the stock app, it wasn't ideal due to group text issues. I was eventually able to get it working after following this process https://www.reddit.com/r/GoogleFi/comments/f6zb57/a_fix_for_if_you_cant_send_mms_messages_because/.
As well, VoLTE was working on my Max phone after forcing it on with the dialer code, VoWiFi was not working however.
So now to my Note 10.
When I first got it it was running the global stable rom, I left it on this during the week I waited for my ability to unlock the phone. I observed the following while using this rom:
- The "stock" phone/contacts and messaging app were replaced by the google versions from the play store
- Google Messages worked completely fine, even offered on its own to enable RCS, group messaging and MMS functioned with no extra steps
- After forcing VoLTE and VoWiFi on through the dialer codes, both were working, calls connected with airplane mode on and only wifi enabled, and after I restored the call log to my eu rom install, the stock miui dialer shows those calls as VoWiFi
What's not working now that I'm on Xaiomi.eu:
- Google messages will not function, similar to how it broke on my Max 3 after the sim switch; MMS does not send, and since group messages are an MMS they don't work either. I can receive texts in a group message but responding gives the toast "Your network is not ready", and every time I open a group message after force closing messages, it says it needs my phone number, if I enter it from that prompt or in advanced, things still don't work, and rebooting/force closing messages results in the number being unset again.
- VoLTE and VoWiFi are not functioning at all
I've at this point tried changing APN settings and doing some reboots with the SIM card in and out as I did before to fix issues on my Max 3, but to no avail. Based on the fact that all these functions worked from the global rom, this seems like something that may be an issue of either Xioami.eu or maybe just the chinese beta, if it's clear it's the latter I'm more than happy to re-post this issue on the mi forums instead.
Thanks in advance, etc etc
