I'm planning a trip and could use some advice about a first-time eSIM user travelling to Japan. What's the best way to handle this with a eSIM TopUp?

Great question! In short: install your eSIM on Wi-Fi before you travel, set it as your data line, and turn on Data Roaming (it never costs extra — the plan is prepaid). It activates automatically when you arrive, and you can top up in the app if you run low.
