Which Networks Does eSIM Use in Costa Rica?

Costa Rica has three mobile operators. Coverage and quality differ significantly between them.

ICE (Kolbi)

ICE (Instituto Costarricense de Electricidad) is the state-owned telecom and has by far the widest coverage in Costa Rica. It covers approximately 90% of populated areas with 4G/LTE and is the only carrier with meaningful coverage in remote and mountainous regions. Most travel eSIM plans use ICE as their primary network.

Claro Costa Rica

Claro is the second-largest carrier. It offers strong 4G coverage in the Central Valley (San Jose, Alajuela, Heredia), Pacific coast towns, and major tourist corridors. Coverage thins out in rural areas and Caribbean lowlands compared to ICE.

Movistar Costa Rica

Movistar (owned by Liberty Latin America since 2021) has the smallest footprint of the three. It covers urban areas and main highways well but has notable gaps in rural tourism areas. Few travel eSIMs use Movistar.

How Is Coverage at Major Costa Rica Destinations?

San Jose & Central Valley

Excellent coverage from all three carriers. 4G/LTE everywhere, including the Juan Santamaria International Airport (SJO), downtown San Jose, Escazu, Santa Ana, and surrounding cities. You will have full connectivity from the moment you land.

Coverage rating: 9/10

Manuel Antonio / Quepos

Manuel Antonio National Park and the adjacent town of Quepos have good 4G coverage on ICE and Claro. You will have signal at the park entrance, on the main trails, and at beachfront hotels. Signal weakens on some interior forest trails inside the park.

Coverage rating: 8/10

Arenal / La Fortuna

La Fortuna town has reliable 4G from ICE and moderate coverage from Claro. The Arenal Volcano area, hot springs resorts, and main roads have usable signal. Coverage drops on the hanging bridges trails and remote adventure tour locations. Arenal Observatory Lodge and similar remote properties may rely on their own WiFi.

Coverage rating: 7/10

Monteverde Cloud Forest

This is where coverage gets challenging. The town of Santa Elena has moderate 4G coverage on ICE. The Monteverde Cloud Forest Reserve and surrounding reserves have very limited to no cellular signal. The thick cloud forest canopy and mountainous terrain block signals effectively.

Coverage rating: 4/10

Tortuguero

Tortuguero National Park on the Caribbean coast is accessible only by boat or small plane. Cellular coverage in the village is limited to weak 3G on ICE. Inside the park’s canal system and rainforest, there is no coverage. Lodges in Tortuguero provide WiFi via satellite connections, which tend to be slow.

Coverage rating: 2/10

Guanacaste Beaches (Tamarindo, Playa Flamingo, Nosara)

The major beach towns of Guanacaste have good 4G coverage from ICE and Claro. Tamarindo, Playa del Coco, Playa Flamingo, and Papagayo Peninsula have reliable service. More remote surf towns like Nosara and Santa Teresa have moderate coverage in town centers but signal drops between towns.

Coverage rating: 7/10

Osa Peninsula / Corcovado

The Osa Peninsula is one of the most biodiverse places on Earth and also one of the least connected. Puerto Jimenez has moderate 3G/4G on ICE. Drake Bay has weak and intermittent service. Corcovado National Park has zero cellular coverage on any network.

Coverage rating: 2/10

Do I Need Offline Maps for Costa Rica?

Yes. Costa Rica’s mountainous terrain and dense rainforest create many dead zones, even in popular tourist areas. Before your trip:

• Google Maps: Download offline maps for each region you will visit
• Waze: Download Costa Rica for offline use (Waze is popular with locals and handles Costa Rica’s address system better than Google Maps)
• Maps.me: Good alternative with hiking trails marked
• AllTrails: Download trail maps for national parks

Costa Rica does not use a traditional street address system. Many locations are described by landmarks (“200 meters north of the church”). GPS coordinates and offline maps are more reliable than typed addresses.

How Much Data Do I Need for Costa Rica?

Light traveler: 200-400 MB/day = 3 GB for two weeks.

Moderate traveler: 500 MB-1 GB/day = 5-10 GB for two weeks.

Heavy user: 1-2 GB/day = 10 GB+ for two weeks.

Keep in mind that many eco-lodges and hotels in Costa Rica have WiFi. You can offload photo uploads and video calls to hotel WiFi and use mobile data primarily for navigation and messaging while out.

Does Uber Work in Costa Rica?

Yes. Uber operates throughout the Central Valley (San Jose, airport transfers, Escazu, Heredia) and in some Pacific coast towns. It requires an active data connection. DiDi also operates in Costa Rica and sometimes offers lower prices.

Outside the Central Valley, Uber availability drops significantly. In beach towns and rural areas, you will rely on local taxis or private transfers. Having your eSIM active for calling or messaging local taxi services is important.

How Do I Set Up an eSIM for Costa Rica?

1. Check device compatibility at compatible devices.

eSIM vs Buying a Kolbi SIM at the Airport

Local Kolbi SIMs are slightly cheaper in raw data cost, but the eSIM saves time and hassle. You arrive connected, skip the airport line, and keep your home number active. For most travelers, the convenience is worth the small price premium.

What About a Regional Latin America eSIM?

If you are visiting multiple Central American countries (Costa Rica + Panama, or Costa Rica + Nicaragua), a regional Latin America eSIM plan may save money versus buying individual country plans. Check regional plans for pricing and country coverage.
