You’ve just touched down at Bangkok’s Suvarnabhumi Airport (BKK), buzzing with excitement for your Thai adventure. The temples, the street food, the beaches—they’re all waiting. But first, the modern traveler’s essential first step: getting connected. You see the long queue snaking from the AIS, TrueMove, and DTAC kiosks. Do you wait, or is there a smarter way?
This is the classic dilemma for travelers in 2025: stick with the traditional local tourist SIM or embrace the future with an eSIM? This guide will break down the pros and cons of grabbing an AIS Tourist SIM versus activating an eSIM for Thailand before you even leave home. We’ll compare them on convenience, cost, and coverage so you can make the best choice for your trip.
The Traditional Route: Buying an AIS Tourist SIM
For years, the go-to move for travelers has been to buy a local SIM card upon arrival. In Thailand, AIS is one of the biggest players, known for its extensive network coverage across the country. The AIS Tourist SIM is a prepaid package specifically designed for visitors.
Pros:
- Reliable Network: AIS boasts one of the best and fastest networks in Thailand, from the bustling streets of Bangkok to the islands of Phuket and Koh Samui.
- Widely Available: You can find them easily at airports, official AIS stores, and thousands of convenience stores like 7-Eleven.
Cons:
- The Airport Queue: This is the biggest drawback. After a long flight, the last thing you want is to spend an hour or more in line.
- Passport Registration: You’ll need to present your passport for registration, which can add to the setup time.
- Physical Hassle: You have to physically swap out your home SIM card, risking losing the tiny chip.
- Fixed Packages: Tourist SIMs come in fixed data and day packages (e.g., 8 days, 15 days), which may not perfectly align with your travel itinerary.
The Modern Alternative: Using a Yoho Mobile eSIM for Thailand
An eSIM (embedded SIM) is a digital SIM card that’s already built into your smartphone. It allows you to activate a cellular plan from a provider without needing a physical SIM card. This technology is a game-changer for international travel.
With Yoho Mobile, you can buy and install your Thailand data plan from the comfort of your home.

Head-to-Head Comparison: AIS SIM vs. Yoho Mobile eSIM
Let’s break it down by the factors that matter most to travelers.
H3: Convenience & Speed of Setup
- AIS SIM: Expect to spend anywhere from 30 minutes to over an hour at the airport buying and registering your SIM. You’ll need to find your SIM ejector tool and carefully swap the cards.
- Yoho Mobile eSIM: The setup takes about two minutes online before you travel. You arrive, turn it on, and you’re online. It’s the definition of hassle-free travel.
H3: Cost & Value
- AIS SIM: Offers good value with packages like a 15-day unlimited data plan. However, if your trip is shorter or you’re a light data user, you might be paying for data you don’t need.
- Yoho Mobile eSIM: The value lies in flexibility. Our plans are often more cost-effective for trips that don’t fit standard tourist SIM durations. You only pay for what you need, giving you better control over your budget.
H3: Network Coverage & Reliability
- The Verdict: This is a tie. Yoho Mobile partners with premier local networks like AIS and DTAC in Thailand. This means you get the same high-speed, reliable 4G/5G coverage you would from a local SIM card, but with all the benefits of an eSIM.
H3: Staying Connected with Yoho Care
- AIS SIM: If you run out of data, you’ll need to find a top-up location (like a 7-Eleven or service center) or navigate a Thai-language app, which can be challenging.
- Yoho Mobile eSIM: Topping up is simple and can be done right in the Yoho Mobile app. Plus, with our unique Yoho Care service, you’re never truly disconnected. Even if your plan runs out, we provide a basic data connection to keep you online for essentials like maps and messaging until you can top up.
Frequently Asked Questions (FAQ)
Is it better to get an eSIM or local SIM in Thailand?
For most tourists, an eSIM is significantly better due to its convenience. You can set it up before your trip and have instant internet upon arrival, avoiding airport queues and the hassle of swapping physical SIM cards. A local SIM is only better if you need a local Thai phone number for specific services.
How much data do I need for a 2-week trip to Thailand?
A 10-20GB plan is usually sufficient for a two-week trip, covering navigation, social media, browsing, and occasional video streaming. With a flexible provider like Yoho Mobile, you can choose a plan that fits your usage and easily add more data if needed.
Can I use my home SIM and a Thailand eSIM at the same time?
Yes, that’s one of the biggest advantages of an eSIM. Most modern smartphones are dual-SIM capable, allowing you to keep your home SIM active for calls and texts while using your Thailand eSIM for affordable, high-speed mobile data.
What happens if I run out of data on my Yoho Mobile eSIM in Thailand?
You can easily purchase a new data package directly through the Yoho Mobile app. Even better, our Yoho Care service ensures you maintain a basic connection for essential apps, so you’re never left stranded without internet access.
