How to Get a Local SIM Card in Koh Samui: Stay Connected, Island-Style!
Picture this: You’ve just landed at Samui International Airport, the sea breeze is calling your name, and you’re itching to post your first photo from Chaweng Beach. But—oh no!—your phone’s as connected as a coconut in the jungle. Don’t worry, fellow explorer! Snagging a Thai SIM card in Koh Samui is as easy as ordering a pad thai, and I’m here to guide you through every step, with a few laughs and local secrets along the way.
Why Get a Local SIM Card?
Let’s be honest—roaming charges are scarier than a surprise monsoon. With a Thai SIM, you get fast 4G/5G data, cheap local calls, and instant access to Google Maps, Grab taxis, and the endless rabbit hole that is Thai food delivery. Trust me, you’ll thank yourself when you’re hunting for the best coconut ice cream near Fisherman’s Village.
Where to Buy Your SIM Card in Koh Samui
1. Right at the Airport: Convenience is King
The moment you walk out of baggage claim at Samui International Airport, you’ll spot the familiar kiosks for AIS, DTAC, and TrueMove—the holy trinity of Thai mobile networks. They’re impossible to miss (think bright neon signs and staff who greet you like an old friend). Prices are a tad higher here, but you get instant setup and help in English.
Tip: If you’re in a rush to hit Lamai Beach or catch the sunset at Big Buddha Temple, this is your fastest option.

2. Local Shops and 7-Eleven: The Savvy Traveler’s Choice
If you want to save a few baht and maybe make a new friend in the process, head to one of Koh Samui’s dozens of 7-Eleven or FamilyMart convenience stores. Nearly every major road from Chaweng to Maenam has one. Just ask the cashier for a SIM (“SIM ka?” if you want to impress them), and they’ll point you in the right direction.
For a more local vibe, pop into a mobile phone shop in the Chaweng Walking Street area. Staff are usually happy to help set up your new SIM, and you might get some insider tips on where to find the best mango sticky rice.

3. Mobile Network Shops: For the Undecided
If you want the royal treatment, visit a flagship store for AIS, DTAC, or TrueMove. These are dotted around main areas like Central Festival Samui, which is also the perfect place for an air-con break and a sneaky snack.

Which Network Should You Choose?
Honestly, AIS, DTAC, and TrueMove are all solid picks on Koh Samui. If you’re planning to explore off-the-beaten-path gems like Silver Beach or the Secret Buddha Garden, AIS tends to have the widest coverage. But for most beaches, restaurants, and temples, any of the big three will keep you Insta-ready.
What Do You Need to Buy a SIM?
Here’s the fun part: Thai law requires you to show your passport to buy a SIM card. The staff will take a quick photo or scan of it, and you’ll be good to go. Don’t worry, no one’s judging your passport photo (we’ve all been there).
How Much Will It Cost?
Prices change faster than the tides, but you can expect to pay around 200–400 THB ($6–$12 USD) for a tourist SIM with 15–30 days of high-speed data. The basic packages usually include heaps of data, some local call minutes, and maybe even a few international call credits to brag to folks back home.
Top Tip: If you’re staying longer, you can always top up your SIM at any 7-Eleven, FamilyMart, or online.
The Setup: Easier Than a Beach Hammock
The staff at shops and kiosks will usually pop the SIM in and activate it for you. In my experience, they’re speedy enough to have you back on TikTok before you can say “Sawadee kap!” If you’re DIY-ing it, just follow the instructions in the SIM pack—most come in English.
Staying Connected Beyond Koh Samui
Planning to island-hop to Koh Phangan for the Full Moon Party or explore the tranquil shores of Koh Tao? Good news: Your Thai SIM will keep you connected across the country. Just don’t drop your phone in the ocean (learn from my mistakes).
Final Thoughts: Your Ticket to Island Adventure
Getting a local SIM in Koh Samui is one of the best travel hacks out there—cheap, easy, and guaranteed to make your trip smoother. Whether you’re posting selfies at Wat Plai Laem, checking reviews for the freshest seafood at Bophut Fisherman’s Village, or navigating winding roads to Hin Ta & Hin Yai Rocks, you’ll be glad you’re always just a swipe away from your next adventure.
