Everything you need to know about your connection and 5G speeds

Does the SE Asia eSIM cover Thailand, Vietnam, and Indonesia?
Yes, our South East Asia regional plan provides seamless 4G/5G coverage across 8+ countries, including Thailand, Vietnam, Malaysia, Singapore, and Indonesia. You can travel from Bangkok to Bali without ever changing your eSIM or losing your connection.
Is the hotspot feature allowed for digital nomads in SE Asia?
Absolutely. All our SE Asia plans include full hotspot and tethering support. This is ideal for digital nomads working from cafes in Chiang Mai, Canggu, or Da Nang who need a reliable backup for their laptop.
Can I use the Grab app across all SE Asian countries with this eSIM?
Yes! Having stable data is vital for using Grab (the local Uber/Uber Eats) in cities like Hanoi, Manila, and Kuala Lumpur. Our eSIM ensures you can book rides and order food the moment you arrive.
Why choose a regional eSIM over local SIM cards in SE Asia?
