SIM or eSIM

Physical tourist SIMs (Dialog, Mobitel, Hutch, Airtel) are sold at the airport arrivals hall and in cities, bring your passport to register (the plastic SIM itself costs about LKR 150, and the regulator caps you at five active connections per passport). eSIM options (Dialog eSIM or global providers like Airalo/Holafly) let you activate a data plan before you land, useful for arrival-day navigation and ride-hailing.

Local eSIMs need a quick online eKYC first: upload your passport scan and a selfie on the operator portal, then a QR code arrives by email. Global aggregators skip that step but charge a steep premium for the convenience: Airalo sells 20GB for about US$18 while Dialog's local portal sells 50GB for roughly US$7. Land on the aggregator, switch to a local pack for the trip.

Coverage

Coverage is strong in Colombo, the south coast and hill-country towns. Expect patchier signal in remote national parks, some east-coast stretches and mountain roads, download offline maps for those legs.

Wi-Fi

Most hotels, guesthouses and cafés in tourist areas offer free Wi-Fi; speeds vary, a local data SIM is more reliable for maps and ride-hailing on the move.
