One plan for a Southeast Asia circuit
The plan covers eight countries: Thailand, Vietnam, Indonesia, Malaysia, the Philippines, Cambodia, Laos and Timor-Leste. Singapore is not included, so if it is on your route you need a separate solution.
A regional plan is worth it when you join up, say, Thailand, Vietnam and Cambodia on one trip. You do not buy a SIM in each country or queue at an airport kiosk. The plan runs on local networks, for example in Thailand, Malaysia, Indonesia, Vietnam and the Philippines. There are fixed GB plans and daily plans, which suit heavy use of maps and ride apps.
In cities coverage is generally good. On islands, in the mountains and in national parks it varies and cannot be promised in advance, so download maps and your key tickets for offline use. Ride apps, maps, messaging apps and mobile payments work over data, but calls and texts are not part of the plan. If you stay in a single country, such as Thailand, that country's own plan may be the simplest choice.
