At the minimum, you should factory reset when crossing borders, and restore from an encrypted cloud backup. But the advice he gives is to use an entirely new phone (new number, new IMEI).

See my other comments, but in regards to authoritian regimes, that doesn’t go far enough. This isn’t buying drugs or breaking into a pipeline construction site. This directly threatening the economy and control of authoritarian nation states that have their economy almost completely reliant on oil that will imprison, torture, or kill someone in their way. Completely different game. World Cup vs your municipal league.
If you are a climate journalist or activist, just stay out of authoritarian places unless you are willing to be tortured or killed. Unless you have CIA/MI6/NSA/GCHQ level skills or whatever your country calls those things, you are in over your head.
