High-speed data, nothing to count

Priced per day — the longer you stay, the better the daily rate. Ideal for streaming, hotspot and longer trips where you'd rather not watch a data meter. A fair-use policy keeps speeds fast for everyone; see each plan for the detail.

  • Best for streaming, video calls & hotspot
  • Great for longer or open-ended trips
  • One price per day — no GB anxiety
By-the-GB plans
3GB10GB20GB

A set bundle, brilliant value

A fixed data allowance (say 3 GB or 10 GB) valid for your travel days. The best-value pick for lighter trips built around maps, messaging and a bit of browsing. Running low? Top up in a couple of taps — nothing to reinstall.

  • Best value for lighter, shorter trips
  • Clear allowance — pay only for what you need
  • Top up any time from your phone

Your guide to Ayutthaya

Ayutthaya eSIM: your local data guide.

Ayutthaya's UNESCO-listed ruins reward a full day of exploring - the Buddha head cradled in tree roots at Wat Mahathat, the Khmer-style prangs of Wat Chaiwatthanaram and the royal gardens of Bang Pa-In Palace. Cycling between temples, an Ayutthaya eSIM keeps maps, opening hours and your train back to Bangkok at your fingertips.

One eSIM for Ayutthaya and all of Thailand. It's the national Thailand eSIM — from $3.14/day with unlimited data, working the same in Ayutthaya as it does the moment you leave it.
Landing at Bangkok Don Muang (DMK), with Suvarnabhumi (BKK) also close by?

Install the QR at home, then switch the eSIM on as you taxi in — you're online before you reach the arrivals hall.
