Sure. Messaging via Signal (or via any other modern mobile messaging app) is designed to be asynchronous and doesn't require all participants of a chat to be online at the same time.
- dependenttypes 7y agoSignal has perfect forward secrecy though. I am unsure how that could be achieved if phone 1 sends a message, the phone gets disconnected and then phone 2 connects to it.
