Use Airalo to purchase a mobile phone data plan eSIM before your international trip

Many modern phones support eSIMs, which makes getting your phone onto a network in another country super easy (barely an inconvenience).

I used Airalo to buy a data plan for my recent trip to the UK. $10 for 3 GB of data (discounted to $7 with a coupon code).

The only trick to getting it to work: I had to turn ‘roaming’ on for the new data plan once I set it up. It's counterintuitive since the whole reason I wanted the in-country plan was to avoid roaming fees. Regardless, I simply disabled my primary USA SIM, and everything worked fine.
