Costa RicaBest eSIM for Costa Rica in 2026

Connectivity Guide for Costa Rica

Costa Rica has three mobile operators: Kölbi (the state-owned operator run by ICE — the largest by subscriber count and the clear leader in rural and coastal coverage), Liberty (formerly Movistar before Liberty Latin America's acquisition — strong in urban areas), and Claro Costa Rica (smallest, with competitive pricing). Most travel eSIMs route through Kölbi or Liberty. 4G/LTE covers nearly all populated areas; 5G is live in San José, Heredia, Liberia, and a growing list of mid-sized cities.

San José and the Central Valley (Alajuela, Heredia, Cartago) have full 4G/5G coverage across every neighborhood and along Highway 1. La Fortuna and the Arenal Volcano area have excellent Kölbi 4G in town, at most hotels, and at the hot springs resorts (Tabacón, Baldi, Eco Termales). Monteverde has reliable coverage in Santa Elena and along the main road but gaps in the cloud forest itself — both Monteverde Cloud Forest Reserve and Selvatura have signal at the entrances and along the main suspension bridges, but not deep on the back trails.

Pacific coast tourism towns — Tamarindo, Nosara, Santa Teresa, Manuel Antonio, Jacó, Dominical, Uvita — all have solid 4G in town and at most beach access points. Guanacaste resorts (Papagayo Peninsula, Conchal, Flamingo) have full coverage. The Osa Peninsula and Corcovado National Park are the biggest connectivity exception in the country — Drake Bay and Puerto Jiménez have Kölbi 4G in town, but deep Corcovado has essentially no signal anywhere. Tortuguero is similar — coverage in the village, none in the canals or on turtle-spotting night walks.

Data is essential in Costa Rica for Uber and DiDi in San José, Google Maps offline downloads (the road network gets unreliable in the rainy season and many shortcuts simply don't exist), Sinpe Móvil (the local instant-payment system — though most tourists use cards or USD), and the various park-ticket apps for Manuel Antonio and other reservation-only parks. Many remote eco-lodges and surf hostels use WhatsApp for booking confirmation. Costa Rica is generally cashless-friendly — Visa, Mastercard, and Apple/Google Pay work almost everywhere outside the deepest jungle.
