I have used the AirAlo app to buy data-only eSIMs for so many international trips. It works well but I have only tried it on iPhones.

Did this yesterday on Android when arriving into Indonesia. While my wife waited in immigration, I used the Smart Gates. I downloaded an eSim via Airalo in just 90 seconds, providing me with enough data to send her a "good luck" message and let her know I'd see her at the hotel if she cleared immigration.
