Why get a Thailand eSIM?
Whether you are eating your way through Bangkok's street markets, hopping between the Andaman and Gulf islands, or temple-hopping around Chiang Mai, staying connected makes Thailand far easier to travel.
A Thailand eSIM from Monsoon Travellers gets you online the moment you land. Buy before you travel, install over WiFi, and your data is ready as soon as you arrive. There are no airport SIM kiosks, no paperwork and no roaming bills.
Coverage and networks in Thailand
Our Thailand plans connect to AIS and DTAC, on 4G and 5G where your phone and location support it. Coverage reaches the cities and the main islands such as Phuket and Koh Samui. Coverage is strongest in major cities and popular tourist areas, and as with any mobile network it can be weaker in remote or rural places.
How much data do you need for Thailand?
It depends on how you travel. As a rough guide:
- Light use such as maps, messaging and the odd search needs about 1GB to 3GB for a short trip.
- Everyday use with daily social, photos and some calls is comfortable on 3GB to 10GB.
- Heavy use or longer stays with streaming, video calls or tethering suits 10GB or more, or a daily plan that refreshes each day.
How your Thailand eSIM works
Choose a plan and check out in under a minute. Your QR code arrives by email within minutes. Install it over WiFi before you fly by tapping the "Install eSIM" button or scanning the code. When you arrive in Thailand, switch on data roaming for the eSIM line and it connects automatically. You will need an eSIM-capable, carrier-unlocked phone.
Will my phone work with a Thailand eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Your phone also needs to be carrier-unlocked. If you are unsure, look for an "Add eSIM" or "Add Mobile Plan" option in your phone settings.
When does my plan start?
Validity begins on first use, when your eSIM first connects to a network in Thailand, not when you buy it. You can install it days ahead over WiFi and it will not start counting down until you arrive.
Does it cover the Thai islands?
Yes. AIS and DTAC reach the main islands like Phuket, Koh Samui and Koh Phi Phi as well as the cities. Signal can be weaker on small or remote islands and on boats between them.
Can I use it in other countries?
These plans are for Thailand only. If your trip covers more than one country, our Southeast Asia and Asia regional eSIMs work across multiple countries on a single plan.
