Thailand SIM Card for Indians 2026: I Tested Every Option So You Don’t Overpay

If you’re an Indian traveler landing in Thailand, the SIM card decision hits you immediately after immigration. I’ve been through Suvarnabhumi Airport six times and tested every option: physical tourist SIMs from all three Thai carriers, eSIMs from Airalo and Holafly, and even Airtel’s international roaming for one trip just to compare costs.
The difference in price, coverage, and convenience is significant — and Indian travelers have specific needs: WhatsApp video calls to family, Instagram uploads from Phuket beaches, and Google Maps navigation that works even on remote islands.
This guide breaks down the Thailand SIM card for Indian travelers with real 2026 prices in INR, coverage maps that matter for Indian itineraries, and the exact counter locations at Bangkok, Phuket, and Chiang Mai airports.

Airtel/Jio Roaming vs. Local SIM: The Cost Reality

Most Indian travelers instinctively enable international roaming before flying. I did this once. Never again.

Airtel International Roaming

Cost: ₹500–800/day

Data Allowance: Unlimited (throttled after 2GB/day)

Validity: Per day

Best For: Emergency only

Jio International Roaming

Cost: ₹575–1,000/day

Data Allowance: Unlimited (throttled after 1.5GB/day)

Validity: Per day

Best For: Emergency only

Thailand Tourist SIM (AIS)

Cost: ₹600–1,200 total

Data Allowance: 15–50GB

Validity: 8–30 days

Best For: All Indian travelers

Thailand eSIM (Airalo)

Cost: ₹800–1,500 total

Data Allowance: 10–20GB

Validity: 7–30 days

Best For: Tech-savvy, short trips

The Math for a 10-Day Trip:
  • Airtel roaming: ₹500 × 10 = ₹5,000
  • AIS 15-day tourist SIM: ₹900 one-time
  • Savings: ₹4,100
My Roaming Experience: I used Airtel roaming for a 3-day Bangkok business trip. The connection was reliable but WhatsApp video calls to my family in Mumbai stuttered constantly. On my next 10-day trip, I bought an AIS SIM at Suvarnabhumi. The difference was immediate — faster speeds, no throttling, and I saved over ₹4,000.
Exception: If you’re in Thailand for less than 48 hours (transit or layover), Airtel/Jio roaming is convenient. For anything longer, buy a local SIM.

Physical SIM vs. eSIM: Which Should Indians Choose?

Price

Physical Tourist SIM: ₹600–1,200

eSIM (Airalo/Holafly): ₹800–1,500

Setup Time

Physical Tourist SIM: 5–10 minutes at airport counter

eSIM (Airalo/Holafly): 2 minutes before landing

Phone Requirement

Physical Tourist SIM: Any unlocked phone

eSIM (Airalo/Holafly): iPhone XR or newer / Pixel 3 or newer

Dual SIM

Physical Tourist SIM: Replaces Indian SIM

eSIM (Airalo/Holafly): Keeps Indian SIM active

Coverage

Physical Tourist SIM: Full Thai carrier network

eSIM (Airalo/Holafly): Same network, sometimes throttled

Top-Up

Physical Tourist SIM: Easy at any 7-Eleven

eSIM (Airalo/Holafly): Limited; usually buy new plan

Customer Support

Physical Tourist SIM: Thai carrier counters

eSIM (Airalo/Holafly): English chat support

Best For

Physical Tourist SIM: Families, long stays, heavy data

eSIM (Airalo/Holafly): Solo travelers, short trips, business

My Take: If your phone supports eSIM and you’re traveling solo for under 10 days, buy an eSIM before you land. If you’re with family or staying longer, get a physical SIM at the airport — you can top up easily and the whole family can hotspot from one device.
Indian Phone Note: Most iPhones sold in India after the iPhone 11 support eSIM. Samsung Galaxy S20 and newer also support eSIM. Budget Xiaomi and Realme phones often do not. Check your phone settings before buying an eSIM.

The 3 Thai Carriers: AIS, DTAC & TrueMove H

Thailand has three major mobile networks. For Indian travelers, the choice matters because coverage varies dramatically between Bangkok and the islands.

AIS

Strength: Best nationwide coverage; works on remote islands and in northern mountains

Weakness: Slightly more expensive

Best For: Island hoppers, Chiang Mai, Krabi, long stays

TrueMove H

Strength: Fastest speeds in Bangkok; excellent 5G in cities

Weakness: Weaker on islands and rural areas

Best For: Bangkok-only trips, business travelers

DTAC

Strength: Good city coverage; competitive pricing

Weakness: Weakest on islands; spotty in Krabi

Best For: Budget travelers staying in Bangkok/Phuket city

My Speed Test Results (February 2026):

Sukhumvit, Bangkok

AIS: 85 Mbps

TrueMove H: 120 Mbps

DTAC: 75 Mbps

Patong Beach, Phuket

AIS: 45 Mbps

TrueMove H: 30 Mbps

DTAC: 25 Mbps

Phi Phi Islands

AIS: 35 Mbps

TrueMove H: 15 Mbps

DTAC: 10 Mbps

Ao Nang, Krabi

AIS: 40 Mbps

TrueMove H: 25 Mbps

DTAC: 20 Mbps

Old City, Chiang Mai

AIS: 55 Mbps

TrueMove H: 50 Mbps

DTAC: 40 Mbps

Doi Suthep Mountain

AIS: 20 Mbps

TrueMove H: 5 Mbps

DTAC: No signal

My Verdict: AIS wins for Indian travelers doing the classic Bangkok-Phuket-Krabi-Chiang Mai circuit. The extra ₹100–200 is worth it for coverage on boats, islands, and mountain roads.

Where to Buy: Airport Counters vs. City 7-Eleven

At the Airport (Recommended for First-Timers)

The Airport Process:

Suvarnabhumi (BKK)

AIS Counter Location: Arrivals Hall, Level 2, Gate 4–5 area

TrueMove H Counter Location: Arrivals Hall, Level 2, Gate 6–7 area

DTAC Counter Location: Arrivals Hall, Level 2, Gate 5–6 area

Hours: 24 hours

Don Mueang (DMK)

AIS Counter Location: Terminal 1 International Arrivals

TrueMove H Counter Location: Terminal 1 International Arrivals

DTAC Counter Location: Terminal 1 International Arrivals

Hours: 6 AM–12 AM

Phuket (HKT)

AIS Counter Location: International Arrivals Hall

TrueMove H Counter Location: International Arrivals Hall

DTAC Counter Location: International Arrivals Hall

Hours: 8 AM–10 PM

Chiang Mai (CNX)

AIS Counter Location: International Arrivals Hall

TrueMove H Counter Location: International Arrivals Hall

DTAC Counter Location: International Arrivals Hall

Hours: 8 AM–9 PM

  1. Walk to arrivals hall after collecting baggage
  2. Approach the carrier counter (all three are within 20 meters of each other)
  3. Show your passport (mandatory for SIM registration in Thailand)
  4. Pay cash or card
  5. Staff inserts SIM, configures APN, and confirms data is working
  6. Takes 5–10 minutes total
My Airport Tip: The AIS counter at Suvarnabhumi always has a queue of 3–5 people. TrueMove H and DTAC are usually empty. If you’re in a rush and staying mostly in Bangkok, TrueMove H is fine. If you need island coverage, wait the extra 5 minutes for AIS.

In the City (7-Eleven)

You can buy tourist SIMs at any 7-Eleven, but the process is slower:
  • Staff may not speak English
  • You must register the SIM yourself via SMS or app
  • Tourist plans are sometimes out of stock; only monthly plans available
My Advice: Buy at the airport. The ₹50–100 premium is worth the convenience and English-speaking support.

Coverage Reality: Bangkok vs. Islands vs. North Thailand

Indian travelers typically do the Bangkok-Phuket-Krabi-Chiang Mai circuit. Here’s where each carrier works:

Bangkok

AIS: Excellent

TrueMove H: Excellent

DTAC: Excellent

Indian Traveler Note: All carriers work. TrueMove H is fastest.

Phuket (Patong/Kata)

AIS: Excellent

TrueMove H: Good

DTAC: Good

Indian Traveler Note: AIS best for beach areas.

Phi Phi Islands

AIS: Good

TrueMove H: Poor

DTAC: Poor

Indian Traveler Note: AIS only reliable option.

Krabi (Ao Nang)

AIS: Excellent

TrueMove H: Moderate

DTAC: Moderate

Indian Traveler Note: AIS for island tours.

Railay Beach

AIS: Moderate

TrueMove H: Poor

DTAC: No signal

Indian Traveler Note: All carriers weak. AIS has basic signal.

Chiang Mai

AIS: Excellent

TrueMove H: Good

DTAC: Good

Indian Traveler Note: AIS best for Doi Suthep mountain.

Pai

AIS: Moderate

TrueMove H: Poor

DTAC: No signal

Indian Traveler Note: AIS only.

Koh Samui

Indian Traveler Note: AIS and TrueMove H work.

The Boat Reality: On longtail boats between islands, AIS maintains 3G/4G signal. TrueMove H and DTAC often drop to 2G or no signal. If you’re booking Grab boats or need maps during island hopping, AIS is essential.

How to Top Up & Check Balance

Check Balance (AIS)

How to Do It: Dial

Code/Method: *121#

Check Balance (TrueMove H)

How to Do It: Dial

Code/Method: *123#

Check Balance (DTAC)

How to Do It: Dial

Code/Method: *101#

Top Up at 7-Eleven

How to Do It: Buy top-up card, scratch code, dial

Code/Method: *100*#

Top Up Online

How to Do It: AIS/TrueMove H/DTAC app or website

Code/Method: Credit card or Thai bank

Buy Data Add-On

How to Do It: Carrier app or dial USSD code

Code/Method: ₹200–400 for 5–10GB

My Top-Up Tip: 7-Eleven staff understand “top up” and “SIM.” Show them your phone and say the carrier name. They’ll sell you a card and often dial the code for you.

  2. Receive QR code by email
  3. Scan QR code in phone settings (Settings → Mobile Data → Add eSIM)
  4. Activate upon landing in Thailand
  5. Keep Indian SIM active for OTPs and family calls
My eSIM Experience: I used Airalo’s 20GB plan on a solo trip. Activation took 2 minutes after landing. Speeds were identical to a physical AIS SIM. The only downside: I couldn’t top up easily when I ran out of data on day 12. I had to buy a second plan.

FAQ 

Q: Which SIM card is best for Indian travelers in Thailand?
A: AIS offers the best coverage nationwide, especially on islands and in northern Thailand. TrueMove H is fastest in Bangkok. For short trips, an eSIM from Airalo or Holafly is more convenient than a physical SIM.
Q: Can I use Airtel or Jio in Thailand?
A: Yes, but international roaming is expensive. Airtel charges ₹500–800 per day for unlimited data roaming. A local Thailand tourist SIM costs ₹600–1,200 for 8–15 days with better data allowances.
Q: Where can I buy a Thailand SIM card at Bangkok Airport?
A: AIS, DTAC, and TrueMove H counters are located in the arrivals hall at Suvarnabhumi Airport, immediately after customs. They are open 24 hours and accept cash and card.
Q: Do I need my passport to buy a SIM in Thailand?
A: Yes. Thai law requires passport registration for all SIM cards. You cannot buy a SIM without showing your passport, even at 7-Eleven.
Q: Can I use my Indian phone in Thailand?
A: Yes, if it is unlocked. Most phones sold in India are unlocked. If you bought your phone through a carrier contract, check with them before traveling. iPhones and Samsung Galaxy phones work perfectly.
Q: Will my WhatsApp work on a Thailand SIM?
A: Yes. WhatsApp works on any Thailand SIM. Your WhatsApp number remains your Indian number if you keep your Indian SIM active (eSIM users) or if you switch back later. Video calls to India use data, not international calling credit.
Q: How much data do I need for a 10-day Thailand trip?
A: 15GB is tight if you video-call family daily and post Instagram stories. 30GB is comfortable for most Indian travelers. I used 22GB on my last 10-day trip.
Q: Can I top up my Thailand SIM after the plan expires?
A: Yes, at any 7-Eleven or through the carrier’s app. Physical SIMs are easier to top up than eSIMs. eSIM users usually need to buy a new plan online.
