I want to use my Pixel with GrapheneOS without a SIM relying on WiFi most of the time and use a mobile hotspot when I am away from home for calls, data, etc. I currently have Sipnetic setup with a VoIP.ms number and MySudo installed with a few numbers. My permanent number is on a separate phone I want to stop using. I want to port that number away from my carrier and just use multiple VoIP numbers for everything.
My problem is my phone not ringing when I get incoming calls with MySudo even with sandboxed play services running and if I let Sipnetic run in the background it annihilates my battery. Does anyone have any potential solutions? I am close to just bagging the idea of SIM free and living with the cell tower tracking and using my permanent number.
