Hello,
I use Tello and an esim on a pixel 9. I am having a terrible time cell service dropping out all the time. I noticed this when I was trying to activate RCS which never completed. When I try to make a call the calls will drop. On my other android phone I have good service and no issues. Thought this might be a permission issue. Also tried to install carrier services. A reboot will sort it out for a bit. Not sure if this is a carrier issue or a config issue.
Any advice would be appreciated.
