You could install grapheneos and only use (pick the message app of the week) for e2ee while only connected to public networks away from your home. Or you could use Facebook messenger while connected to your home wifi.
Are you communicating with your family back home in the country ruled by an oppressive regime? Or are you chatting with Aunt Bertha about her haemorrhoids?
