The questions everyone asks us
Using an eSIM in Southeast Asia
A Southeast Asia eSIM keeps you online across Thailand, Malaysia and Singapore on a single plan, ideal for a multi-country trip through the region. Install it before you fly and switch it on when you arrive, ready for Grab, maps and messaging.
Cities, islands and the crossings between
Coverage is generally strongest across the cities, from Bangkok and Kuala Lumpur to Singapore, and around the main tourist areas, so a trip taking in all three is easy on one plan. On the Thai and Malaysian islands, in the rainforest interiors and out on the water between islands, signal thins or drops away, so download offline maps before island-hopping. This plan covers the three named countries, so if your trip extends to other Southeast Asian countries, check the plan details or look for a wider regional plan.
How much data
A week or two of maps, Grab, messaging and photos across the three is often around 5-10GB for a week and 10-20GB for two, with more for heavy streaming or hotspot use. These are starting points, and actual use varies.
Travel eSIM FAQs
Top-up availability depends on the plan. Some eSIMs can be topped up, including certain unlimited plans, while others may require a new plan once the current one ends or runs out. Check the individual plan details for your selected option.
