For mass texting, aren't there online services you could access via Tor and pay with a virtual credit card or even in bitcoins?If you're using such a service from a carrier, once more, ensure you access a web proxy as a front behind which you're using Tor. Then depending on the level of introspection the carrier has, they either think you're a dude who wants to do mass texting, a dude who wants to be anonymous and wants to do mass texting, which is not exactly illegal, but they don't know that you *really* are an anonymous dude that wants to do mass texting and tracking or picking up server log files is a dead end.Protip: Either take the batteries out of your phones until usage and ensure they're charged, or else you pop them into a Faraday Bag (each one inside a smaller Faraday cage pouch). This makes cellular tracking and remote microphone activation completely impossible.Also: Look into steganography and the plausible deniability of pornography.
