Asia eSIM data plans — Japan, Korea & more

Asia is the region our travellers fly to most: a business week in Seoul, a family holiday in Thailand, a ski trip to Japan or a stopover in Singapore. Every plan below is a prepaid travel eSIM — you install it before departure, switch the line on when you land, and the data is live the moment the handset connects to a local network. No queue at the airport counter, no plastic card to lose.

Two kinds of plan are collected here. Single-country plans (Japan, South Korea, China, Malaysia, the Philippines, Vietnam and more) keep the price low when you stay in one place and put you on the local network you want. Multi-country bundles — Asia 4, Asia 8, Asia 20, Asia 30 — cover a list of countries with a single balance, which is the calmer and usually cheaper choice on a multi-stop route: one QR code, one expiry date, one top-up if you run out.

Your Mongolian number keeps working: the GlobalSIM eSIM is a data line, so calls and SMS still arrive on your regular number in the same phone. Plans are prepaid in MNT at the price shown on each card, with no hidden roaming charge, and extra data can be added from My GlobalSIM once the plan is active. Check your handset before buying — dial *#06# and if an EID appears, the phone supports eSIM.
