Bandaranaike International Colombo Airport

Official Languages: Sinhala, Tamil

English Works as a Link Language between Sinhala and Tamil Speakers and Is Common in Hotels, Tourism Services, and City Businesses. It Is Less Consistent in Rural Areas, so Simple, Clear Phrasing Usually Works Better than Slang

Mobile Network: Coverage Is Solid in Cities, Towns, and Main Travel Corridors, with 5G Opening across Major Cities from Late 2025 and 4G as the Everyday Standard. Coverage Thins in National Parks and Hill Country. Older 2G and 3G Still Run, so a Phone without 4G Still Gets Calls and Texts, but Data Can Be Slow or Unavailable outside 4G Areas

Roaming/SIM/eSIM: An eSIM Bought before You Fly Is Convenient, Working the Moment You Land with No Counter Queue. A Local SIM Usually Gives Better Value for a Longer Stay and Is Commonly Bought at the Airport or in City Shops against Your Passport. Roaming Suits a Very Short Trip Best. Whichever You Choose, a 4G-Capable Phone Gives the Most Reliable Data, since a Phone Limited to 2G or 3G May Struggle for Data outside the Main Areas

Cards Are Widely Accepted at Hotels, Larger Restaurants, Supermarkets, and Shops in Colombo and Main Tourist Areas. Cash Still Matters for Small Eateries, Markets, Tuk-Tuks, Rural Areas, and Some Guesthouses, so Carry Small Notes for Everyday Payments

Tipping Is Appreciated but Not Always Mandatory. Many Hotels and Restaurants Add a Service Charge, Often around 10 Percent, so Check the Bill First. If No Service Charge Is Included, Round Up or Leave about 5 to 10 Percent for Good Restaurant Service. Small Tips Are Typical for Hotel Porters, Drivers, Guides, and Housekeeping When Service Is Helpful
