 I downloaded the [Airalo][5] app before I left, which offers cheap international data plans using e-SIM cards. The app works great, no complaints there, but mixed feelings about having a working phone while on vacation -- it was cool to be able to send photos + make video calls, but my company's going through some tough times and I couldn't pull myself away from Slack and email.
