Kölbi vs Claro vs Movistar
A travel eSIM for Costa Rica rides on one of three networks: Kölbi, Claro, or the Liberty-Movistar network, or switches between them. In San Jose or a main beach town the choice barely matters; all are fast and reliable. On a back road to a cloud forest or a remote stretch of Guanacaste, the choice can decide whether you have a map. This guide explains what separates them, so you can read a product page and know whether the network behind it fits your route.
The operator your eSIM uses is the most underweighted factor in choosing a Costa Rica plan. Price gets the attention; coverage off the tourist track is what you will actually feel.
The three networks at a glance
Costa Rica's mobile market is led by Kölbi, the operator of the state utility ICE, which opened to competition over a decade ago. Kölbi retains the widest reach as the heritage national operator. Claro, the regional América Móvil brand, is a strong competitor across the cities and main routes. The third network operates under Liberty, which absorbed the former Movistar operation, and is well built in the populated areas. For a traveler, the meaningful contrast is Kölbi's rural reach against the others' strong but more urban-focused footprints.
| Factor | Kölbi | Claro | Liberty-Movistar |
|---|---|---|---|
| Overall reach | The widest, strong rural. | Strong in cities and main routes. | Strong in populated areas. |
| Rural & forest reach | The best of the three. | Thinner off the main routes. | Thinner off the main routes. |
| City speed | Fast. | Fast. | Fast. |
| Best for | Rural routes, forests, back roads. | City and main-corridor trips. | City and main-corridor trips. |
Where the difference actually shows up
In San Jose, the Central Valley, or a popular beach town like Tamarindo or Manuel Antonio, all three networks deliver good service and the choice is close to irrelevant. The gap opens when you head somewhere less commercial: a winding road to Monteverde, a small town in the Guanacaste interior, or the approaches to a remote lodge. There, Kölbi's heritage coverage often reaches where the others are weaker, which matters precisely on the routes that make a Costa Rica trip special.
Because the networks have different gaps in different places, the most resilient option for a Costa Rica trip that leaves the main hubs is a multi-network eSIM that connects to whichever has signal where you are. Instead of betting on one network's rural map, you get the broadest combined coverage. For a stay in San Jose and the popular beaches the advantage is small, since any network works, but for the forests, back roads and remote regions it meaningfully improves your odds of a signal.
Speed: a non-issue between them
On raw speed in well-covered areas, the three networks all deliver more than enough for any traveler's needs. Nobody chooses between them on speed; the deciding factor is reach. The relevant question in Costa Rica is whether you will have any signal at a forest lodge or on a mountain road, and that is about which network has built towers there, which is most often Kölbi.
How to tell which network your eSIM uses
A well-documented Costa Rica eSIM product page states the network or networks it connects to. For Costa Rica specifically, a Kölbi-based or multi-network option is usually the better choice for any trip beyond the Central Valley and main beaches, given how much the rural reach varies between operators.
- Kölbi-based or multi-network. The best choice for forest, back-road and remote-region itineraries thanks to the widest reach.
- Claro or Liberty-Movistar based. Perfectly fine for a city and main-beach trip.
- Unspecified. If a product page does not say which network it uses, ask before buying, particularly for a rural or forest-heavy trip.
If your trip is San Jose plus a popular Pacific beach, the network question is largely academic. All three will serve you well. Save the analysis for trips that genuinely leave the main hubs into the cloud forests, the Osa Peninsula and the rural interior, where the network actually changes your experience.
Where we land
For the broadest reliability across any Costa Rica itinerary, a Kölbi-based or multi-network plan is the safer default, because it covers the cities and beaches just as well while also reaching the rural and forest areas the others miss. A Claro or Liberty-Movistar based plan is fine for a city and main-beach trip. Our Costa Rica plans are built to ride the strongest available network for a given location, which is exactly what a country with this much off-grid terrain calls for.

FAQ
Is Kölbi, Claro or Movistar best for a traveler in Costa Rica?
Kölbi, the state utility operator, has the widest reach, especially in rural and forest areas, making it the safer overall choice. Claro and the Liberty-Movistar network are strong in the cities and main tourist routes but thinner off them. For a city and main-beach trip any network works well; for the cloud forests, the Osa Peninsula and rural routes, a Kölbi-based or multi-network eSIM pulls clearly ahead.
What happened to Movistar in Costa Rica?
The former Movistar operation in Costa Rica was absorbed under Liberty, so the third major network now operates under that umbrella. For a traveler it remains a well-built network in the populated areas. The meaningful coverage contrast in Costa Rica is between Kölbi's wide rural reach and the strong but more urban-focused footprints of the other operators.
Does it matter which network my Costa Rica eSIM uses?
It depends on your route. In San Jose, the Central Valley and the popular beach towns, all three networks deliver good service and the choice is close to irrelevant. The further you travel into the cloud forests, the Osa Peninsula, Guanacaste's interior or the back roads, the more a Kölbi-based or multi-network plan matters for staying connected.
What is a multi-network eSIM and is it worth it for Costa Rica?
A multi-network eSIM can connect to more than one Costa Rican operator and selects the strongest available signal. For Costa Rica it is the smart default on any trip beyond the main hubs, because the networks have different rural gaps and a multi-network plan gives you the broadest combined coverage. For a stay in San Jose and the popular beaches the advantage is small, since any network works.
How do I know which network a Costa Rica plan uses before I buy?
A well-documented eSIM product page states the network it connects to, whether Kölbi, Claro, the Liberty-Movistar network, or multiple. If the page does not specify, ask the provider before purchasing, especially for a forest or rural-heavy trip where the network choice changes your coverage. For city and main-beach trips the information matters less because all networks perform well.
