Registration required to connect — look for the sign-in page after joining the network.
A local eSIM (Dialog or Mobitel, sold at arrivals or installable before landing via Airalo/Holafly) is the more dependable option than terminal Wi-Fi — Dialog in particular has solid coverage right at the airport and along the west coast.
Reports genuinely disagree on this one — some describe free sessions capped around 3–4 hours, others describe a paid voucher system with airport computers as the free fallback. Don't plan a long working session around it; treat a local eSIM as the backup, not an afterthought.
