Heading to rural areas or islands (Samui, Phangan)? AIS has the widest coverage. Staying around Bangkok? True/dtac is fast and reliable in cities. Many global eSIMs auto-select their partner network — if you'll travel widely, one that runs on AIS is the safe pick.
Since February 2025, Thailand requires foreign travelers to complete ID (passport) registration to use a SIM/eSIM. AIS's official eSIM requires passport eKYC before activation. Data eSIMs from global brands like Airalo and Holafly typically work without it — but rules can change, so check each official site for the latest.
Every AIS official plan includes a Thai phone number with call credit (100 THB). Among global brands, Airalo's dtac 50GB plan (100 call minutes) and Nomad's unlimited 15/30-day plans (Thai number) support voice. The rest are data-only — app calls like LINE and WhatsApp still work.
Many unlimited plans apply a fair-use policy (FUP) that can throttle speed after heavy use — check each provider's terms before buying. For reference, tourist SIMs start around 299 THB at Bangkok airport counters, but queues and opening hours are a hassle; set up an eSIM in advance and you're online the moment you land.
Connectivity basics to sort out before you land.
