I purchased, unfortunately BTC payment option isn't there, presumably to reduce piracy (each copy has a watermark which I guess is linked to your fiat payment method)
Still it's well worth $15 and goes into detail how to:
  • Purchase a pixel
  • Set up with Graphene and improve privacy settings
  • Make use of Twilio to run multiple numbers at low cost
  • Connecting Twilio with VOIP and SMS services
  • Lots of good opsec such as use of Faraday bags
  • Lots (and lots) of other great opsec and configuration tips
The parts I'd disagree with are in regards to putting an actual sim in your phone, but of course privacy / security is a spectrum.
The author is totally right that Pixel + Graphene is the ONLY good option these days for mobile comms.
One thing that was missing from the PDF was a mention of Simplex Chat, presumably because it's still fairly new. Being open source, self-hostable, and having had a security audit, probably somebody should brief the author about it!
