1. Never ever have Signal installed on the phone during border crossing. The presence of the app itself may trigger them (speaking from first-hand experience).
2. Having an empty Telegram account may look suspicious. My recommendation is to have two separate Telegram accounts, with the "unpatriotic" one in the separate profile only.
3. Never ever use WhatsApp for anything "unpatriotic". It's way of deleting messages leaves traces ("This message has been deleted") which may rise suspicions.
As for email, I just don't have any email clients installed on my "patriotic" profile. They all go to the "unpatriotic" one.
