After choosing Simple SMS as a replacement for the default Graphene SMS app, I started wondering: how do SMSs compare to other messenging methods in terms of 1: privacy; and 2: security...?

Specifically, does anyone know how to compare them to: Discord, Signal, WhatsApp? (ok I know at least enough not to ask about Facebook Messenger, Snapchat, Instagram and TikTok 😂)

Thanks!

    Well, for starters, Signal and Whatsapp have end-to-end encryption which makes it objectively more private/secure than SMS which is unencrypted and inherently un-private. (Signal is recommended between those two by the way to avoid obvious bad things, cough facebook/meta cough)
