*Then there's always the "Old Fashioned Way" by Telegram Sam
Telegram Messenger is a globally accessible
freemium,
encrypted,
cloud-based and
centralized instant messaging (IM) service.
The application also provides optional
end-to-end encrypted chats (popularly known as "secret chats") and
video calling,
VoIP, file sharing and several other features.
Telegram provides optional end-to-end encrypted chats.
Cloud chats and groups are encrypted between the client and the server, so that ISPs and other third-parties on the network cannot access data.
Users can send text and voice messages, make voice and video calls, and share an unlimited number of images, documents (2 GB per file), user locations, animated stickers, contacts, and audio files.
Telegram messages are heavily encrypted and can self-destruct.
Telegram's default messages are cloud-based and can be accessed on any of the user's connected devices.
Users can send messages to other users individually or in groups of up to 200,000 members.
Sent messages can be edited up to 48 hours after they have been sent and can be deleted at any time on both sides.
Messages in all chats, including groups and channels, can be set to auto-delete after 24 hours, 7 days or a month, although this will only apply to messages sent after the auto-delete timer is enabled.
Fast. Secure. Powerful.
