After comparing the various plans available in this ever-popular destination, we share the best eSIM for travel in Thailand
Thailand has long been a favourite destination for travellers, backpackers and digital nomads alike. From the cafés of Chiang Mai to the beaches of Koh Lanta, it’s an easy place to settle into a rhythm of travel and remote work.
However, one thing we’ve learned over the years is that good internet can make or break a trip. Reliable data helps with everything from navigation and ride-hailing apps to uploading photos, checking emails and joining video calls.
In the past, staying connected abroad meant hunting down a local SIM card, queuing at airport kiosks or relying on unreliable hotel Wi-Fi. These days, eSIM technology offers a much simpler solution.
After using eSIMs extensively on our travels, we’ve found them to be one of the easiest ways to get online abroad. Below, we explain how they work, why they’re useful in Thailand and how Airalo compares with other popular providers.
What is an eSIM?
An eSIM (embedded SIM) is a digital version of a traditional SIM card built directly into your device. Instead of inserting a physical SIM, you simply download a mobile plan via QR code or an app.
Once installed, the eSIM connects your phone to local networks in the same way a regular SIM would.
For travellers, the advantages are obvious:
- No need to buy a SIM card at the airport
- You can install your plan before you travel
- Your primary SIM can remain in your phone
- You can switch between networks and countries easily
Adoption of eSIM technology has grown rapidly in recent years as more smartphones now support it and travellers look for cheaper alternatives to international roaming.
For digital nomads or remote workers, it’s particularly useful as it allows you to stay connected almost immediately after landing.
What is the best eSIM for travel in Thailand?
There are now dozens of travel eSIM providers available, but Airalo has become one of the most widely used.
Founded in 2019, the company offers eSIM plans for more than 200 destinations. Its Thailand packages are designed for travellers who want quick and affordable mobile data without needing to buy a local SIM card.
Here are a few reasons it works well for Thailand.
Simple setup: Airalo’s setup process is straightforward. After purchasing a plan through the website or app, you install the eSIM and activate it when you arrive in Thailand. The process typically takes only a few minutes.
Flexible plans: Thailand eSIM plans are available in a range of data allowances and durations, making them suitable for everything from short holidays to longer remote-work stays.
Reliable local networks: Airalo connects to major Thai networks, which generally provide strong coverage in cities such as Bangkok and Chiang Mai, as well as many popular island destinations.
No roaming surprises: Because the plans are prepaid, you know exactly how much data you’re buying in advance. That means no unexpected roaming charges when you get home.
