Traveling to Bangkok, Thailand, is an adventure waiting to happen. With its vibrant street life, awe-inspiring temples, and mouth-watering street food, it’s no surprise that millions of travelers flock to this Southeast Asian gem every year. But before you dive into exploring Bangkok’s buzzing markets or lounging on a Thai beach, there’s one essential item you need to sort out—how you’ll stay connected. Let’s dive into the best options for buying a SIM card and compare various data plans so you can stay online without breaking the bank.
Why You Need a SIM Card or eSIM in Thailand
Whether you’re navigating the busy streets of Bangkok, booking Grab rides, or sharing your latest adventure on Instagram, having reliable data is crucial. While many cafes, hotels, and restaurants offer free Wi-Fi, it’s not always dependable, and when you’re out exploring, public Wi-Fi can be scarce. That’s where having a local SIM or eSIM comes in handy. It provides not just convenience but also a more secure connection.
What is an eSIM?
Before we get into traditional SIM cards, let’s talk about eSIMs. An eSIM (embedded SIM) is a digital SIM that allows you to activate a cellular plan from your carrier without using a physical SIM card. You can easily purchase and activate an eSIM through your phone, and it’s becoming increasingly popular for travelers. With an eSIM, you won’t need to worry about swapping SIM cards or finding a local store—just download, activate, and you’re good to go.
Here’s why eSIMs are a fantastic option:
- Quick and easy setup: Activate it from your phone in minutes.
- No need to switch physical SIM cards: If you’re traveling between multiple countries, an eSIM can be much more convenient.
- Perfect for short trips: Most eSIM plans offer competitive short-term data options.
How to Buy an eSIM for Thailand
You can buy an eSIM before you leave for Thailand or after you arrive, but buying it in advance is often the best choice, so you don’t have to scramble upon arrival. At Superhero eSIM, we offer affordable plans specifically designed for travelers like you. Simply download our app and select a Thailand data plan. It’s as easy as that.
Steps to buy an eSIM with Superhero:
- Download the Superhero eSIM app or browse your favorite destinations on the web

Traditional SIM Cards: Where and How to Buy Them in Bangkok
For those who prefer a traditional SIM card, Bangkok makes it relatively easy. You can purchase a SIM at Bangkok Suvarnabhumi Airport (BKK) upon arrival or in various shops around the city. If you’re arriving at the airport, head to one of the mobile operator kiosks located right after you exit customs.
Top SIM Card Providers in Thailand:
- AIS
- TrueMove H
- DTAC
These are the three major mobile providers in Thailand, and they each offer tourist SIM cards. Here’s a quick rundown:
- AIS: AIS is one of Thailand’s largest mobile providers and offers excellent coverage, even in remote areas. Their tourist SIM options start with 3GB of data for about 299 THB (around $9 USD) and go up to unlimited data for around 999 THB (roughly $30 USD).
- TrueMove H: Another big player in Thailand, TrueMove H offers a 299 THB SIM with 3GB of data or a 599 THB plan with 8GB of data. TrueMove’s coverage is solid across cities and popular tourist areas.
- DTAC: DTAC provides similar options, with a basic 3GB SIM starting at 299 THB and an unlimited data plan for around 799 THB (approximately $24 USD). Like AIS and TrueMove, DTAC has good coverage in urban areas and popular destinations.
Where to Buy SIM Cards:
- Suvarnabhumi Airport: The easiest option, with SIM cards available right after you exit the arrival gate.

- Mobile Operator Stores: You’ll find branches of AIS, TrueMove H, and DTAC in all major shopping malls and markets.
What to Look For in a SIM Card or Data Plan
When choosing a SIM card or eSIM, consider the following:
- Data allowance: How much data do you need? Thailand has many SIM options ranging from 3GB for a quick trip to unlimited data for more extended stays.
- Duration: Most tourist SIM cards and eSIM plans are valid for 7, 15, or 30 days.
- Coverage: All three major providers offer good coverage in urban areas like Bangkok, but if you’re planning to venture into remote areas, check that your provider covers those spots.
- Speed: Thailand offers 4G LTE speeds in most places, but if you want to future-proof your experience, consider a provider that offers 5G where available.
Comparing eSIM and SIM Card Plans for Thailand
| Provider | Data Plan | Price | Validity | Type |
|---|---|---|---|---|

Choosing between a SIM card and an eSIM for your trip to Thailand comes down to personal preference. If you’re looking for a hassle-free option, an eSIM from Superhero eSIM is the way to go—download, activate, and you’re connected.
