# Does It Work in Thailand? (2026-11-11)

Thailand offers fast 5G tourist connectivity on AIS and True/DTAC, Grab ride-hailing with foreign cards, and Visa/Mastercard tap-to-pay on Bangkok MRT.

> **Quick take:** Skip the 220 THB Thai ATM fee by linking a Wise or Revolut card inside Grab and using contactless Visa/Mastercard on Bangkok MRT; install an AIS/DTAC eSIM before arrival.

## Service Compatibility Matrix

- **Thailand eSIM vs. Airport Tourist SIM** [works]: Pre-installed eSIMs connect at the gate without waiting at Suvarnabhumi passport registration queues; AIS provides the strongest island coverage. ([Guide](https://doesitworkin.com/thailand/esim-tourist-sim))
- **Grab Ride-Hailing & Food Delivery with Foreign Cards** [works]: Accepts foreign Visa, Mastercard, and Wise/Revolut debit cards; add your card before departure so 3D Secure SMS verification goes to your home SIM.
- **Thai PromptPay QR Codes for Tourists** [conditional]: Standard Thai bank PromptPay QR codes do not work with Western bank apps; tourists need TAGTHAi Pay&Tour or cash for street stalls.
