Cannot call at several mobile phones

it may not be o.s. related. it may be eg25g firmware related and volte. so i recommend updating firmware either stock or partially open source firmware.

if stock firmware, i recommend 30.007.30.007 version.

i recommend these for both stock and partially open source, https://github.com/the-modem-distro/pine...ETTINGS.md .

Ok, thanks so much for your input. I'm researching on Mobian, trying to install the stock firmware recovery with fastboot, like they tell here:
https://github.com/Biktorgj/quectel_eg25_recovery
But finally it keeps on terminal telling <waiting for any device> without success.

I've keep on searching. I've opened an issue with this on github web. I'll tell you my progress.
