If I'm travelling for leisure, I would prefer things like Slack to stay as far away from me as possible. Preferably on my work machine that I left behind on my home continent. If I travel for work, or if my employer requires me to have Slack (or similar) on my device and with me at all times, then they can provide me with a dedicated device for that purpose and that purpose alone. It's then their problem to worry about operational security associated with having work comms on a device that might have to be compromised by a foreign government. Even the most basic android phone supports email and text (sms) out of the box. My country enjoys incredibly deep WhatsApp penetration, and subsequently it's become the default mode of communication for almost everyone. WhatsApp runs on almost anything. Back in the day they even had .jar files to download and install on your Symbian dumb phones. I'm talking here about a "burner" device as it's sometimes called. The minimum viable communicator that you can take with you so that you can keep in touch with friends and family and be reachable in the case of an emergency. But you make an interesting argument for not needing to go with a new device. A beat-up second-hand mid-ranger from a few years ago will probably work just as well. I have a drawer full of them, and if I don't have any, they can be had for very cheap.
