Sri Lanka has excellent 4G coverage in tourist areas, and a local SIM card is the cheapest way to stay connected. The three main operators are Dialog, Mobitel, and Hutch — Dialog has the widest coverage.
Where to buy: SIMs are available at the airport arrivals hall, official operator stores, and most phone shops. You will need your passport for registration.
Cost: A tourist SIM with 30 GB of data, local minutes, and free WhatsApp costs around USD 5–10. Most plans are valid for 30 days.
Tip: Buy at the airport on arrival for the fastest setup. The kiosks in arrivals are official and offer tourist plans in English.
If you prefer not to switch SIMs, eSIM providers like Airalo also offer Sri Lanka data packages, though the local SIM is usually cheaper and faster.
