Nice thing about element is that it’s open-source, as well as the backend messaging system. Element is just a very popular Matrix front-end.
Can’t use Signal since I’m using it with my main number already.
I don't believe they are blocking VPN services, so may I also suggest express VPN or NordVPN. These are the two top dogs and they seem to trade back and forth which review says his number one and they're reasonable with wide coverage and everything else. Something to think about after you find somebody to help you get what you want lol
Element requires you to leave an email address with them at account registration. Session is better in that regard since it doesn't require an email address or phone number. Just created an account on both. I can't speak for Session's security and privacy measures in any other regard.
