What to do for cellular data when traveling overseas? For a while, my answer was the app GigSky, but on a recent trip abroad, I had all sorts of problems, so I posted a plea for help on social media. Special thanks to Noah Kagan (@noahkagan) and everyone else who responded to my query in this Twitter thread. Airalo was extremely easy to use and did the trick. To avoid expensive roaming bills when traveling abroad and using data, you can install the Airalo app (iOS, Android) and buy a local eSIM. In minutes, you will have data at an affordable price. The app might be easiest, but I personally did something slightly different: I visited their website on my laptop and then took a pic of the QR code with my phone. Here’s the official description: “Airalo is the world’s first eSIM store that solves the pain of high roaming bills by giving you access to 200+ eSIMs (digital SIM cards) globally at affordable prices."
