Buying a local SIM at arrivals usually means a passport, a form and a queue, in a language you may not read. An eSIM is already on the phone when the wheels touch down.


A multi-stop East Asia trip usually crosses three or four of these 11 destinations by short-haul flight, and one plan follows the whole route.

Choose a plan, scan the QR code that lands in your email, and switch the line on when you arrive. Install it on wi-fi before you travel - data only starts counting once you connect at the destination.

A long weekend and a month in Asia Lite need very different plans, so you choose the data and the days. Around 3GB covers a week of maps, messaging and a daily scroll; 10GB carries a fortnight with video calls home.
The QR code arrives by email seconds after payment. Scan it on wi-fi before you leave, and the Asia Lite line comes alive on its own once you land and switch it on.
Stuck on the install, or the line will not attach after landing? Message us and a person replies, whatever the hour is where you are.
Phones from the iPhone XS onward, and most Android flagships since 2019, carry an eSIM slot alongside the usual tray. Adding a travel plan writes it to that slot, and your everyday SIM stays where it is.
Scanning the code from your email writes the plan onto that handset. It installs once and stays there, so scan it on the phone you are actually travelling with.

Thailand, Vietnam, Malaysia, Singapore, Indonesia, the Philippines and Cambodia - the same eSIM switches between them automatically as you cross borders.
No, install the Asia Lite eSIM once before you fly and it works across all seven countries without reactivating at each stop.
Yes, it's a data-only eSIM, so your regular SIM stays active for calls and texts in the other slot throughout the region.
Top up the same eSIM from the Olysim app at any point, wherever in the seven countries you happen to be.
