Thailand is one of the most popular destinations for Indian travelers — and one of the most confusing for mobile data. Suvarnabhumi Airport's SIM card queue is legendary (expect 45 minutes at peak times). Happy to Sim, DTAC Tourist SIM, AIS... the choices at the kiosk are overwhelming.
Here's the smarter approach: install your eSIM before you board, land connected, skip the queue entirely.
Thailand Networks: What You Need to Know
Thailand has three major carriers:
- AIS — Best overall coverage, 5G in Bangkok, most reliable for tourists
- True Move H — Good urban coverage, strong in Phuket
- DTAC — Budget option, coverage gaps outside major cities
Most travel eSIMs in Thailand run on AIS or True Move H networks.

Currency and Payments

- ATMs widely available; Kasikorn Bank has the best rates for foreign cards
- Most tourist areas accept cards; smaller vendors are cash-only
Frequently Asked Questions
Is eSIM supported on all phones in Thailand? Most phones released after 2019 support eSIM: iPhone XS+, Samsung Galaxy S21+, Google Pixel 4+, OnePlus 9+. Check your model before buying.
How fast is the internet in Thailand? Bangkok and major tourist areas have excellent 4G/5G coverage. Rural areas and islands may have weaker signal. Koh Samui, Krabi, and Phuket all have good coverage.
Can I use my travel eSIM for maps and navigation? Yes. Google Maps works perfectly on travel eSIM data. Download offline maps for areas with potentially weak coverage.
What's the cheapest way to get data in Thailand from India? Travel eSIM from Trovio (when launched) or Airalo currently offer the best INR-equivalent prices. Avoid Jio/Airtel roaming packs — they cost 2–3x more per GB.
Do I need to activate the eSIM before landing? Most eSIMs activate automatically on landing when your phone connects to a Thai network. Some require manual activation in your device settings.
