SIM Card and Internet in Thailand — How to Stay Connected

Physical SIM on Arrival

SIM kiosks at major airports offer tourist packages with data, usually in a quick process with your passport.

eSIM in Advance

For those whose device supports it — you can buy an eSIM in advance and arrive already connected, without swapping a physical card.

Local SIM or eSIM: How to Choose

A physical SIM from a kiosk at the airport is a convenient solution if you prefer to ask someone and sort everything out on the spot. A passport is required for registration when buying. Large providers such as AIS and True offer tourist packages for various periods. An eSIM has the advantage that you can install it before the flight and arrive connected, but you need a device that supports it and isn't locked to another provider.

Check whether the package includes data only or also calls, and how many days it's valid. It's always worth estimating the data volume according to your usage, because navigation, video and travel apps consume a lot.

Coverage, Speed and Remote Areas

Coverage in cities and tourist areas is usually good, but on small islands, in the mountains and in the jungle it can weaken. If you plan a trip to such places, download offline maps in advance. It's important to know that public networks in hotels and cafés aren't always secure, so consider using a VPN when logging in to bank accounts.

Apps Worth Installing Before Landing

A ride-hailing app like Grab is important from the first moment, so set it up in advance: see the Grab and Bolt guide. An offline map, a translation app and a messaging app are the basics. The LINE app is also widely used in Thailand. Before you land, download your booking confirmations to your device too.

Roaming, Monthly Plans and Remote Work

Roaming packages from your Israeli provider may be convenient but are usually more expensive than a local one, so compare prices before the trip. Anyone staying for a long period or working remotely should consider a monthly package and two sources of connection — details in remote work from Thailand. And for first-time travelers, the first-timer's guide summarizes what to arrange before the flight.

Common Problems and Solutions

If the new SIM doesn't work, start by restarting the device and checking that roaming and data are turned on. Sometimes you need to wait a few minutes after activation, because registration with your passport is carried out at the provider. If an eSIM won't install, check that the device is not locked and that you have a Wi-Fi connection during installation.

Keep your original Israeli card in a safe place, and consider leaving it active in a second slot if your device supports it, because some banks and verification services send SMS messages to the Israeli number. If you have a dual SIM, you can use local data and your Israeli number at the same time. And if the problem continues, go to the provider's kiosk, where they usually help quickly.
