Nice guide. Just some other OPSEC stuff we have done for occasional problems in the field training human rights defenders and journalists (who needed specific solutions)... You can always use a call relay. So you can give people one phone number that relays to your own real number (for voice calls) - although an voice call is obviously more vulnerable than Signal call etc. Ditto, AFAIK there is the ability to setup a relay for SMS through an Android. I can't remember the app but basically people could SMS that number and it relays to you real number. Before people jump on me, yes I am aware of the weaknesses of both of the above but sometimes a specific type of threat model requires these two tricks. I recommend it unless you are aware of the trade offs.
