Of course, they are entirely within their right to just take your phone, and then never give it back. You "officially" have legal recourse to get it back, but in reality, you plain won't. If you _really_ care about this, travel without your phone, and travel with a minimal-account wiped laptop that runs, has some apps, and has zero work or personal data on it. Stick some steam games on it at most. Then get a burner phone once you're in the country you need to be in, let people you need to talk to know what your new temporary number is, and restore your data from a secure source that you can access using your laptop. Then when you leave, "burn" the phone and properly wipe your laptop again.
