Mobile data is cheap and coverage is good along the main tourist routes, though it can be patchy in national parks and deep in the hills. A local SIM is the easiest way to use maps, ride-hailing apps and messaging.
Buying at the airport
The two biggest networks have counters in the arrival lobby at Bandaranaike International Airport, after customs. You need your passport; SIM cards must be registered to the buyer under the national regulations, and the staff do this for you. Both networks also sell eSIMs.
