Because you mentioned that you want to degoogle, you probably care about your privacy. Since SMS Messaging and ordinary telephony are an old and insecure technology and don't respect your privacy from your carrier, you should probably stick with end to end encrypted messaging. Best by using Signal messenger, since it is easy to setup and I understand that for some entering the world of privacy may mean a steep learning curve. Also look at VPN providers like Proton VPN, who can help with location tracking and help against geofencing. It is time to replace old standards with new, ones that respect us.
