Best eSIM for Costa Rica 2026: 14 Providers Compared

Kolbi, Claro and Liberty cover San José, the Central Valley and the Guanacaste beaches in 4G, with 5G spreading, but Monteverde's cloud forest and the Osa Peninsula around Corcovado are where Costa Rica's signal gets thin. Costa Rica runs on connection. Whether you are navigating the winding roads from San Jose to La Fortuna, coordinating a zip-line booking above the Monteverde cloud forest, checking surf reports for Tamarindo, or translating a soda menu at a roadside stop, your trip depends on a mobile signal that actually holds up. An eSIM is the cleanest way to get one: install it before you fly, land at Juan Santamaria or Liberia International, and you are online the moment your phone finds a network. No SIM tray, no queue at a carrier kiosk, no passport photocopies for a prepaid registration.

Claro, Liberty or Kölbi: speeds and 5G in 2026

Costa Rica has three national mobile networks: Kölbi, run by the state utility ICE, Claro, and Liberty, which took over Movistar's network. In the nPerf 2026 barometer, covering April 2025 to March 2026, Claro ranks first with 72,349 nPoints and an average download speed of 79.6 Mbps, well ahead of Liberty (53,723 nPoints, 23.7 Mbps) and Kölbi (49,179 nPoints, 21.5 Mbps).

5G is still a city story. Claro and Liberty won 5G spectrum in the January 2025 auction, and the regulator Sutel's field tests between January 5 and June 30, 2026 measured Claro's 5G at 186.6 Mbps on average against 34.1 Mbps for Liberty, as reported by DPL News in September 2026. Sutel found no Liberty 5G signal in Cartago, Guanacaste, Puntarenas or Limón, and Kölbi does not yet sell 5G commercially. Outside the Central Valley, plan on 4G whichever network your eSIM uses; the networks for each Simsima plan are listed in its details.

Kölbi's chip turista and other local SIMs

Kölbi sells a chip turista, a prepaid tourist SIM with a Costa Rican number, and Claro and Liberty have their own prepaid SIMs. All three require your passport, because prepaid lines are registered to the buyer's identity. You buy them at operator stores and authorized sellers, including at the airports, and the line is active once the registration is done.

A local SIM makes sense if you need a Costa Rican number for SINPE Móvil payments or for a landlord who only texts. For a two-week trip of driving, tours and hotel stays, a travel eSIM installed at home is already working when you pick up the rental car. The tables below show what travel eSIM providers charge for Costa Rica, so you can compare them with the price quoted at the counter.

Signal from Arenal to the Osa Peninsula

San José, Heredia, Alajuela and Cartago have dense 4G, and the route from Juan Santamaría into the capital is well covered. On the Pacific side, Liberia, Tamarindo, Playas del Coco, Nosara and Sámara get reliable 4G near the town centers, as do Quepos and Manuel Antonio, with occasional drops on the jungle trails inside the national park. La Fortuna has strong 4G in town and along the main hotel road toward Arenal Volcano.

The weak spots are where the roads end. Monteverde and Santa Elena have signal in the villages and near the reserve entrance, but rarely on the hanging bridges or inside the cloud forest. The Osa Peninsula has basic coverage in Puerto Jiménez and very little inside Corcovado National Park. The gravel roads of the Nicoya Peninsula between Sámara, Malpaís and Santa Teresa, and the shortcut around Lake Arenal to Monteverde, are where most drivers first lose service.

Costa Rica eSIM Plans Compared (2026)

Here is a comparison of the main Costa Rica eSIM plans against the leading international providers. Simsima offers plans on the local networks, with transparent pricing.

Unlimited data plans

Capped data plans

These prices move with the market, so check the row that matches your itinerary. A Simsima Costa Rica plan installs before departure and activates on arrival, when it first connects to a Costa Rican network.

Data for ten days: San José, La Fortuna, Monteverde and Guanacaste

A classic first loop: one night in San José, three nights in La Fortuna for Arenal and the hot springs, two in Monteverde for the cloud forest, then four on a Guanacaste beach such as Tamarindo or Playas del Coco before flying home from Liberia.

• Waze or Google Maps for about 10 hours of driving across the loop, plus searches for sodas and tours on the way: 1 to 2 GB
• WhatsApp with tour operators, shuttles and the rental car company, plus photos and stories from the volcano and the beach: 2 to 3 GB
• Video calls and some streaming in the evenings, when lodge Wi-Fi in Monteverde or on the beach is slow: 2 to 3 GB

That totals around 5 to 8 GB, which fits the larger capped plans in the table. Remote workers in Santa Teresa or Nosara, or a group sharing one phone as a hotspot in the rental car, should look at the unlimited plans instead.

How to install your Costa Rica eSIM

Installation takes about three minutes and is best done at home on Wi-Fi, before you fly. After purchase, Simsima sends a QR code and manual installation details by email. The eSIM then activates on its own when it first connects to a Costa Rican network, so its validity does not start until you land.

1. Buy your Costa Rica eSIM on Simsima before you fly
2. Open the email on another screen, such as a laptop, so you can scan the QR code with your phone
3. On iPhone, go to Settings, then Cellular, then Add eSIM; on Android, go to Settings, Connections, SIM manager, Add eSIM
4. Label the new line Costa Rica, set it as your data line and turn on data roaming for that line only
5. Keep your home line for calls and SMS codes, and turn off roaming on it to avoid charges
6. Land at Juan Santamaría or Liberia and check that the Costa Rica line shows signal

What if the eSIM doesn't activate on landing?

If your line shows No Service after landing, run through this checklist before contacting support. First, confirm the Costa Rica line is toggled ON in your cellular settings and set as the data line. Second, enable data roaming for that specific line, this is required on most travel eSIMs even though you are physically in the destination country. Third, restart the phone: a reboot forces a fresh network scan and resolves most first-connection failures. Fourth, in Settings, manually select a network operator (Kolbi, Claro or Liberty) instead of Automatic. If none of that works, contact Simsima support rather than deleting the profile: a deleted eSIM cannot be reinstalled on your own.

Waze, SINPE Móvil and the apps Ticos use

• Waze is the local favorite for driving, especially for traffic on Ruta 27 to the Pacific and on the Interamericana through Guanacaste
• WhatsApp is how tour operators, shuttles, hotels and rental car companies confirm pickups and changes
• Uber and DiDi work in San José and parts of the Central Valley; outside the capital, red licensed taxis and hotel shuttles are the norm
• The national weather institute IMN publishes rainfall alerts that matter in the green season, from May to November
• SINAC's online ticketing is how you book entry to parks such as Manuel Antonio and Poás
• SINPE Móvil, the instant payment system many small businesses use, needs a Costa Rican bank account and phone number, so visitors pay by card or cash instead

What an eSIM won't solve in Costa Rica

• It is data only, with no Costa Rican number, so SINPE Móvil and any service that sends a code to a local number are out of reach; WhatsApp calls cover the rest
• Inside Corcovado, on the Monteverde hanging bridges and on the Nicoya gravel roads, no network holds a steady signal, eSIM or not
• 5G is limited to parts of the Central Valley, so most of your trip runs on 4G
• Hotspot sharing with travel companions depends on the plan, and your phone must support eSIM and be carrier-unlocked

Crossing into Panama or Nicaragua by road

Overland trips often continue south to Bocas del Toro through the Sixaola border or to Panama via Paso Canoas, or north to Granada through Peñas Blancas. A Costa Rica plan stops working once your phone attaches to a Panamanian or Nicaraguan tower. For a short add-on, a second country plan works; for a longer route through Central America, the Latin America guide below compares multi-country options.
