🇹🇭 Thailand Telecom Comparison
Find the perfect SIM or eSIM for your Thailand adventure
💡 Pro Tips
- Airport vs City: Airport SIM prices are often inflated. If you can wait, buy in the city for better rates.
- Test Before You Leave: Activate and test your SIM/eSIM at the airport before heading to your hotel.
- Google Maps Offline: Download offline maps before relying solely on mobile data in remote areas.
- Phuket/Samui: AIS has the strongest coverage. Good for beach clubs and boat trips.
- Koh Tao/Phi Phi: TrueMove H often performs better for diving and island hopping.
- Bangkok/Chiang Mai: All providers work well. Choose based on price.
Important Notes:
- Prices: Approximate and may vary. Always verify current rates with providers.
- Physical SIMs: Require pickup at airport booths or local stores. Bring your passport for registration.
- eSIMs: Activate instantly via QR code. Ensure your phone supports eSIM before purchasing.
- Island Coverage: Remote islands may have spotty coverage. AIS typically has the widest reach. TrueMove H is known for better signals on diving islands like Koh Tao.
- Top-ups: Physical SIMs can be topped up at 7-Eleven, Family Mart, or via provider apps. eSIM top-ups are app-only (credit card required).
- Speed Throttling: "Unlimited" eSIM plans may throttle speeds after daily limits (typically 1-2GB/day at full speed).
- WhatsApp Calls: Data-only eSIMs work fine for WhatsApp, LINE, or Skype calls - you just can't use regular phone calls.
- Dual SIM Strategy: Many travelers use a cheap eSIM for data + keep their home SIM for 2FA/important calls.
