Why Thailand is different
"Thailand is the biggest eSIM market in Southeast Asia by volume — but single-carrier plans miss the Koh Tao and Similan diving coasts entirely."
Thailand is one of Asia's most eSIM-friendly markets. Airport booths sell tourist SIMs easily, but the markup runs 3–4× wholesale, and you still lose time in the queue. Buy before you board and walk past the booths.
Our Thailand plans use AIS and TrueMove H. AIS is the dominant provider in Bangkok, Chiang Mai, and the main islands. TrueMove H has stronger coverage on the Andaman coast and remote diving spots.
Coverage you can actually measure.
We run Thailand on 2 carriers so your profile falls back automatically if one signal drops. Coverage figures are measured against our own uptime data, not carrier marketing claims.

Troubleshooting
- Koh Tao, Koh Phangan, and Similan Islands have patchy AIS — TrueMove fallback covers them.
- Full Moon Party nights on Koh Phangan overload all carriers — plan for connectivity gaps.
- Thai 5G is real but limited to central Bangkok, Phuket Town, and Chiang Mai city centre.
Who Thailand eSIM is built for.
Island-hopper
AIS + TrueMove failover keeps signal from Koh Samui to Koh Tao and Similan. Offline maps load before ferries.
Digital nomad (Chiang Mai)
Unlimited 30-day plan at nomad-friendly pricing. Hotspot allowed. Chiang Mai 5G is reliable enough to work from cafes.
Buddhist trail pilgrim
Temples in Chiang Rai, Ayutthaya, and Sukhothai have reliable 4G — navigate without a guide.
