Lots of groups have used https://briarproject.org/ successfully in the past, I've heard. Assumes you're using Android though which if you're using a burner, you most likely are.
Successfully in terms of communication or in terms of security?
Successful communication is easy if you don't worry about security. Just post it on Instagram.
How do you know if your security is successful? How do you know if your messages were intercepted and read, your app was hacked, data was extracted from it, etc.? The attackers (authorities or otherwise) are not going to tell you.
I’d go as far as to assume there’s no evading surveillance in a strict sense.
If you attend, leave your phone home (atypical usage), go with other people / meet them there / other people you know are there (facial recognition / gait analysis / clothing preference) those are all good data points to predict with high probability where you are and what you’re up to, especially given your typical movements, data usage patterns, purchasing habits, friends / acquaintances / social media interactions are all in at least a few databases.
Take the security measures you’re willing to make the tradeoffs for.
If history is anything to go by, we’re only ever an election, or other political churn, away from your particular sets of beliefs / identifiers being persecuted, or at least your least favourite political prisoners being released and coming after you.
And, as you allude to, relying on the security practices of others has its own problems. Even Perfect Forward Secrecy etc etc provides little help against Rubber Hose Cryptography.
>If history is anything to go by, we’re only ever an election, or other political churn, away from your particular sets of beliefs / identifiers being persecuted, or at least your least favourite political prisoners being released and coming after you.
it goes other way around too - you are only one election cycle away to be pardoned.
And if the protest is succrssfull, you dont need a pardon anyway.

>A special law shields you? How does a law shield you from persecution?
We won, this is how.
>Being pardoned doesn't help much if you're dead.
There is an escalation ladder you need to climb to attain martyrdom. It takes effort and courage and not everybody can or should do it. It's okay to be on the part of the process that provides moral support to the more hardcore participants.
Depending upon which OS are on. If Android - Briar is the most famous and obvious choice. On iOS? There are not any options really but wasn't any usable one around a year back the last I had checked.
On iOS there are not many options for P2P w/o Internet (I assume that is what you meant - otherwise if you want P2P over Internet then there are some options although not really "truly" P2P of course - and of course if Internet is shut down or overwhelmed then it will be down). There's https://github.com/berty/berty (the last time I tried it was crashing incessantly but it might have improved). I do not know of anything else really (there might be few but I am not sure).
