Where to Buy SIM Card in Bangkok, Phuket, and Chiang Mai (2025 Update)

Thailand is one of the most visited countries in the world, and staying connected here is easier than ever. Whether you’re exploring the bustling streets of Bangkok, relaxing on the beaches of Phuket, or enjoying the mountain views of Chiang Mai, having a local SIM card or eSIM is essential for navigation, bookings, and keeping in touch.

In this guide, we’ll show you where to buy a SIM card in Thailand and compare it to using eSIM for ultimate convenience.

Buying a SIM Card at the Airport

Pros:

• Immediate access to data after landing

• Staff available to help with setup

• Variety of plans for tourists

Cons:

• Prices may be slightly higher than in the city

• Longer queues during peak hours

Airports with SIM card counters:

• Bangkok Suvarnabhumi (BKK) – AIS, DTAC, TrueMove H booths in Arrivals Hall

• Bangkok Don Mueang (DMK) – Telecom counters after customs

• Phuket International Airport (HKT) – SIM card kiosks near baggage claim

• Chiang Mai International Airport (CNX) – Smaller selection, but still major providers available

Buying a SIM Card in the City

If you want cheaper prices or more data options, buying in the city is a good idea.

Best places:

• Official telecom stores (AIS, DTAC, TrueMove H) in malls like MBK Center (Bangkok), Central Festival (Phuket), or MAYA Mall (Chiang Mai)

• 7-Eleven and FamilyMart convenience stores (limited selection)

• Mobile phone shops in local markets

Tip: Bring your passport for registration, as required by Thai law.

Using eSIM Instead

For many travelers in 2025, eSIM has replaced the need to visit a shop entirely.

Benefits of eSIM:

• Buy and activate online before you arrive

• No passport registration in-store

• Instant connection upon landing

• Keep your home SIM for calls and SMS

Which Option Should You Choose?

• Short trip & want quick setup → Get eSIM before you travel

• Budget-conscious & okay with setup time → Buy SIM card in the city

• Landing late at night → eSIM is more convenient, as stores may be closed

Recommended eSIM for Thailand

Look for plans with:

• 5–15GB for short stays (under 8 days)

• Unlimited data for long stays (30 days)

• Network switching between AIS, DTAC, and TrueMove H for best coverage

Final Thoughts

Whether you buy a SIM card at the airport, in the city, or choose an eSIM, Thailand offers excellent connectivity for travelers. For most, buying an eSIM online before the trip saves time, avoids queues, and ensures you’re connected the moment you arrive.
