Hook into SMS, do a key generation and agreement protocol, done. Lots of ways to use SMS and even voice, oob, internet, etc, to get or confirm a key. Crypted text over SMS not efficient or fast, but is possible, and easily put into a simple app. Even use one time pads, TOTP ratchets, cut and paste into SMS, etc. Old school still works. If user has IP on their phone, whether via telco or wifi, they can use anything they want over that. Just another motivation for users to drop the iOS/Android stack and try a Pinephone / Librem, or at least get a unix laptop and tether it. For those using phone provided browsers, even Firefox and even tor variations exist as alternatives... https://en.wikipedia.org/wiki/Firefox_for_Android https://en.wikipedia.org/wiki/Firefox_for_iOS https://www.torproject.org/download/ https://itunes.apple.com/us/app/onion-browser/id519296448 At least Firefox isn't Google, and accepts donations via Mozilla.
