Thailand eSIM on TrueMove H, from $8.90

TrueMove H, part of True Corporation (merged with dtac in 2023) — Thailand's largest operator group. Across Bangkok, Phuket, Chiang Mai and the main tourist routes, coverage is excellent and you shouldn't overthink the choice of network. The one honest exception: for remote islands like Koh Tao and Koh Phangan, AIS has a coverage edge. Most tourists spend their trip in the cities and main routes, where this makes almost no difference.

No — it's a native TrueMove H local profile, not an international roaming product. Most "Thailand eSIM" offers from global providers are a roaming line that simply connects to TrueMove H or AIS towers under a foreign agreement; this one is a real Thai subscriber profile issued directly on TrueMove H's own network, the same way a Thai resident's SIM would be. It installs before you fly — while you still have reliable home Wi-Fi to download the profile — and then sits dormant until your phone connects to TrueMove H on arrival, at which point it activates automatically with no dialing codes, in-store registration, or manual configuration needed.

Yes — free incoming calls and SMS are included on every plan, useful for hotel confirmations, ride-hailing apps and two-factor codes that call or text a local number. It's a receive-only number: you can't make outbound calls or texts from it, and there's no airtime top-up for that — data is the only thing you buy or renew.

All five plans are unlimited — there's no point where your data runs out. The 8-, 10-, 15- and 30-day plans run at full TrueMove H speed (the 10-day plan is a limited-time promotion from the network, so its terms may change when it ends). The 7-day plan gives you 35GB at full speed, then keeps going unlimited at a minimum speed of 1Mbps, which is enough for maps, messaging, social media and browsing. All plans run on TrueMove H's network, falling back to 4G automatically wherever 5G isn't available.

No — this is eSIM-only. Your phone needs to be eSIM-capable and carrier-unlocked. Keep your home SIM in the other slot for calls on your usual number; let this eSIM carry your Thailand data.
