If you are a high value target, you should not carry normal phones made for normal people.
Its sad that none of the dumb phones were built with security in mind. Linux phones are the second best option, GrapheneOS and CalyxOS would be the least you should go.
Alot of people told me “No these old phones cannot do modern crypto” and I am like they managed to put in full 3d games for Nokia 5130c2 and 5300 such as “1916 Dogfight” and “Need for speed carbon” I am sure these phones have enough processing power to do all the modern crypto if someone tried to.
Modern crypto is often faster than old crypto. For example eliptic curve crypto in software is faster than AES in software

Cryptography is what you yourself first need. Also - depends for what, if we are not using hardware acceleration. Encrypting text - yeah. Voice - may be more problematic.
Also consumer hardware and software is generally not designed to protect high value targets.
It’s intended for protection against crooks and hooligans, which is necessary for businesses, which is an incentive for vendors.
Providing protection against nation states is something which may even be considered a bad thing.
Maby it would be problematic for real time communication like voice when it comes to encryption but these phones do not even try to do text encryption bugs me.
I think we should just feel okay to say “I dont know what advice to give you if you are targeted by a nation”
Me feeling left out.
