I think this is where F-droid and Briar have a (short-lived in this instance) chance to shine. Since Briar allows communication between phones without access to the Internet, and F-droid allows to direct transmit apps between phones as well.
I wonder what similar solutions exist in the iOS ecosystem.
we tried briar during the recent mass protests in Serbia and the bluetooth connection never worked, it was unable to connect to any of the contacts that were previosly added using the normal 4G connection.
