I know it is a long shot, any remote chance Xiaomi Redmi Note 7 will have Wifi Calling support activated?
I have tried a few things to get it working.
- Flashed Lineage OS (and other custom ROMs)
- Flashed the latest firmware and vendor files from the latest stock ROM.
- Using short codes *#*#4636#*#* shows
- VoLte Provisioned
- Video Calling Provisioned
- Wifi Calling Provisioned
IMS Status:
- IMS Registration: Not Registered
- Voice over LTE: Unavailable
- Voice over Wifi: Unavailable
- Video Calling: Unavailable
- UT Interface: Unavailable
So far no luck...
(correction) Meanwhile, I try an old Apple iPhone 4S, with a 2 degrees sim, and it works without any problem (that sim doesn't work on the Redmi Note 7 though). 🤦♂️
Since the Sure Signal boosters are being retired, we will have no cellphone reception at home at all after the 10th of December.
It would be nice to not have to buy an expensive new phone just to get wifi calling working, or a cellphone booster. 🙄
