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.

Data allowance depends on the plan length you choose — see the plans below for the exact GB on each, since shorter and longer trips are priced with different allowances rather than one fixed amount stretched across every duration. All plans run on TrueMove H's 5G network where available, falling back to 4G automatically in areas without 5G coverage, so you get the fastest available speed at your location without needing to configure anything. If you're unsure how much you'll need, a rough guide is that light use (maps, messaging, social media, some browsing) needs noticeably less than daily video streaming or heavy tethering — pick a plan with headroom rather than cutting it exactly to your expected use, since running out mid-trip means buying a second eSIM rather than simply topping up the same one.

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.
