If you’re planning a trip to Thailand, one of the first things you’ll want to sort out after landing is your internet connection. From booking taxis to navigating Bangkok’s busy streets, having reliable data is a game-changer. The good news? Getting a local SIM card in Thailand is quick and easy. Before I left I was convinced that I was going to get an eSim (and you can read all about why here). Instead I opted to take two phones, put the foreign SIM in one and hotspot from one to the other, mainly because I’d heard how changing the SIMs can affect TikTok reach. If you are a creator this is another thing to consider. Regardless, there are a few things you should know before you buy.

Where to Buy a SIM Card in Thailand

When you arrive at Bangkok (BKK) or Phuket (HKT) airport, you’ll immediately spot kiosks selling tourist SIM cards. They’re everywhere—sometimes even before baggage collection. Staff will set everything up for you, from inserting the SIM to configuring your phone.

👉 The catch? Airport SIM cards are much more expensive. You’re essentially paying for convenience and instant connectivity.

If you can wait, head to a 7-Eleven (there are thousands across the country) or an official mobile store once you’re in town. You’ll get the same SIM packages for a fraction of the price. For example, a package that costs 600–700 THB at the airport might be half that at a 7-Eleven.

⚠️ Important: If you’re buying a SIM card at a 7-Eleven, you must bring your passport. Thai law requires SIM registration, and the staff will take a photo of your passport to set it up for you. No passport, no SIM.

Which Network Should You Choose?

Thailand has three main providers: AIS, TrueMove, and DTAC.

• DTAC is often considered the best option for tourists thanks to reliable coverage, fast speeds, and affordable packages.
• AIS and TrueMove are also solid choices, but DTAC tends to perform better in rural areas and islands. When we arrived back in Thailand from Cambodia through our route, we were on a time crunch to find a SIM and the only one left at the 7/11 near Khao San Road was a TrueMove one. It was mostly fine but we didn’t have the best connectivity when we were in Koh Tao especially.

If you’re heading off the beaten track (think northern mountains or remote beaches), DTAC is your safest bet.

We paid £5 for 30GB for 30 days which was a fraction of the cost of the ones we were quoted at the airport! We actually managed to use free wifi at the airport and then out and about for basically an entire day until we got one 😅 #thailand #emilyvictoriatravels #backpacking#CapCut

How Much Does a SIM Card Cost in Thailand?

Prices vary depending on the package, but here’s a rough guide if you buy outside the airport:

• 7–15 days unlimited data: 150–300 THB
• 30 days unlimited data: 300–500 THB

At the airport, expect to pay double or even triple those prices.

Local SIM vs eSIM in Thailand

If your phone supports eSIM, you might want to skip the kiosks altogether.

• Cost: eSIM plans are usually more expensive than physical SIMs.
• Convenience: No need to swap out your current SIM card—just activate the eSIM with a QR code.
• Coverage: Many eSIM providers partner with major Thai networks (including DTAC), so you’ll often get the same signal. Just make sure before you purchase a plan that the provider is DTAC as some eSIM companies will use other networks.

👉 There are lots of different eSIM providers out there – personally I’ve only used Airalo once whilst on holiday in Turkey (you can use my code EMILYV3 for $3 off) and I don’t have anything negative to sat about it yet.

Quick Tips for Getting a SIM in Thailand

• Bring your passport – required for SIM registration at 7-Eleven and mobile shops.
• Decide based on need – if you need instant data for a Grab ride or to contact your hotel, grab an airport SIM. If not, wait until you’re in the city.
• Consider an eSIM – faster to set up, instant connectivity and often just as reliable (as long as you are on the best network).

Getting a local SIM card in Thailand is easy and affordable, especially if you wait until you reach a 7-Eleven or mobile shop instead of buying at the airport. For most travelers, DTAC offers the best balance of price and coverage. But if you want to skip the hassle altogether, an eSIM is the most convenient option.

Whichever route you take, staying connected in Thailand will make your trip smoother, safer, and way more enjoyable.

Enjoy Your Travels
