What to sort out for Sri Lanka once the flight is booked.

Sri Lanka is one of the few destinations where the arrivals hall genuinely solves this for you. The main operators — Dialog, Mobitel, Hutch and Airtel Lanka — run tourist SIM desks inside the terminal at Bandaranaike, and a passport is all that is needed to register a prepaid connection. If you land during normal hours and do not mind a queue, a physical local SIM is a perfectly reasonable choice here.

The case for an eSIM instead is about the gap, not the price. You clear immigration, you need to message the driver, confirm a homestay, or pull up a map, and the SIM desk queue is between you and all of it. An eSIM you activate before boarding in India means data is live the second the aircraft doors open. It also leaves your Indian number reachable on the second slot for OTPs — which matters more than most people expect, because Indian banking, UPI and airline apps all still authenticate to that number.

International roaming from an Indian operator is the third option and the one worth checking rather than assuming. Because Sri Lanka is a short-haul destination, several Indian carriers bundle it into inexpensive regional day packs, and for a three-or-four-night trip that can be simpler than managing a second profile. The thing to watch is the fair-use data cap on those packs, which is usually generous for messaging and tight for navigation and video calls.

Wherever you buy, expect real coverage differences by geography. Colombo, Negombo, the southern coast from Bentota through Galle to Mirissa, and the Kandy corridor are well served. Ella, Haputale, Horton Plains, the Knuckles range and parts of the east are patchier, and the mountain train line drops signal repeatedly.

Travel insurance is not one product. A typical international policy bundles emergency medical treatment and hospitalisation abroad, medical evacuation or repatriation, trip cancellation and curtailment, delay, and baggage loss or delay. For Sri Lanka the medical and evacuation halves are the ones that earn their keep — private hospitals in Colombo will treat you well and will expect the bill settled, and the standard of care available outside Colombo and Kandy drops off quickly, which is what makes evacuation cover relevant rather than theoretical.

The Sri Lanka-specific risk is transport and water. Scooter and tuk-tuk hire is easy and lightly regulated, the coast road carries fast traffic, and surfing at Arugam Bay, Weligama and Hikkaduwa plus diving off Trincomalee are the reasons most travellers come. Those are precisely the activities a standard policy either excludes or covers only under an adventure-sports extension. Riding a two-wheeler without the licence class the policy requires is the most common way people find out their cover does not apply.

Whether insurance is a documented condition of entry is a separate question from whether it is a good idea, and the answer has moved. Sri Lanka has added and removed health-cover conditions on its entry authorisation more than once in recent years. Treat any blog or agent that tells you it is definitely required — or definitely not — as out of date, and check the Department of Immigration and Emigration before you buy.

Almost everyone arrives at Bandaranaike, and almost nobody's first night is next to it. The expressway link means central Colombo is a quick, predictable drive, and Negombo — where a lot of first nights are spent precisely because it is close — is closer still. The trip that catches people out is the run south to Bentota, Galle, Mirissa or Tangalle, or the climb inland to Kandy and Sigiriya. Those are proper road journeys, and arriving on a late flight to negotiate one at the rank is a bad start.

Your options from the terminal are the airport taxi counters, a metered ride-hailing pickup, or a transfer booked in advance at a fixed price. Pre-booking is worth most when the destination is far, when you are landing at night, when there are more bags than a sedan takes, or when you want a driver who will stop on the way — a lot of travellers turn the Galle run into a half-day with stops rather than a straight transfer.

For getting around after that, the Southern Expressway makes coastal hops fast, while the hill country is slow by design. Sri Lanka's intercity trains are the good kind of slow, and the coastal line south from Colombo is a genuinely pleasant way to move between beach towns without booking anything.

Sri Lanka rewards loose planning almost everywhere except on rails. The train seats are the exception that has to be handled from India; the rest of the country is small enough, and supply is deep enough, that a day or two of notice is usually plenty.

The other thing to fix early is the shape of the trip. Sri Lanka's classic loop — coast, hill country, cultural triangle — looks compact on a map and is not, because the roads are winding and the trains are unhurried. Booking activities against a realistic driving day, rather than an optimistic one, saves more of the holiday than any single reservation.

Sri Lanka runs an electronic travel authorisation system that visitors apply for before travel, and Indian passport holders are inside that system. What has changed repeatedly is the detail underneath it — which nationalities get a fee waiver, which portal is the official one, how long the authorisation is valid, and whether health cover is a stated condition. Several unofficial sites present themselves as the authorisation portal, so start from the government department rather than from a search result.

The standard supporting expectations are the ordinary ones: a passport with sufficient remaining validity, a confirmed return or onward ticket, an address for your first nights, and the means to support yourself. None of that is exotic, but immigration can ask for any of it.

Verify the current rules before you book anything non-refundable. Nothing on this page is an entry guarantee, and an authorisation is permission to travel, not a promise of admission — the officer at the border makes that decision.
