This is cheap enough to throw in the trash as you board for your flight home.
Connectivity is a slightly larger problem. In some places you can get a prepaid SIM card for less than a dollar, other places need some form of registration. Really depends on the country and local laws.
It's probably possible to go SIM-less and just hop between open hotspots.
Maybe you know this and it's just an expression, but just in case: never throw electronics in the trash. At the very least the battery is toxic and needs recycling, but other parts of it probably too.
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.
Probably being bad is a feature here, because you won't be tempted to use the phone that's infected.
However I found a much better use case is to keep your phone's os secure by putting all dodgy apps in "my knox". This way I could've had what's app and give it access to all my 1 contact I prepared for it etc.
These days I don't know if they still have "my knox" feature on the flagship models as, I decided to get a different phone.
However for going to an autocratic country I would just buy a burner phone (or not go there in the first place).
Does anyone else have any experience with this app?
This also seems like a great use case for privacy focused OSes for unlocked phones. I’ve been trying to get into CalyxOS or GrapheneOS for a while. Just waiting for either to come to the Pixel 7 Pro. I wouldn’t throw it afterwards, but probably wouldn’t connect it to any home networks without nuking it once or twice.
It seems like this would be good practice these days for any international travel.
