Before you go to Japan and South Korea
What the plan covers, and what is worth sorting out before you fly.
One plan, every stop
Add a country and it joins this plan. No second eSIM to install, no second bill to reconcile, and the same number of profiles on your phone as when you started.
Pay for the data you need in the actual destinations you are going to
Pick a size, use it, top it up from the browser when you need more. Nothing renews on its own and nothing expires the day you land home.
Support in your language
A person, 24/7, in the language you booked in. Not a chatbot, and not a form that answers on Monday.
