Summary
The best Costa Rica eSIM for 2026 gives you Kölbi/Claro data from ~US$5, live before you land at Juan Santamaría (SJO) and far cheaper than US roaming. Costa Rica remains one of the most-visited nature destinations in the Americas, and a local eSIM keeps maps, rideshare, and WhatsApp working from Arenal to Guanacaste.
Why an eSIM beats roaming in Costa Rica
Costa Rica's mobile market is led by Kölbi (the ICE state carrier) and Claro, which cover San José, the Central Valley, Arenal/La Fortuna, Monteverde, Manuel Antonio, and the Guanacaste beaches. A travel eSIM rides those local networks, so you get the same signal a Costa Rican phone would — without the US$10–15 per day US carriers charge to roam. You install the eSIM from an emailed QR code on Wi-Fi before departure, and it connects automatically on arrival.
Keep your home SIM in the phone with roaming off for calls and bank codes, and let the eSIM carry data. For side trips, see our Mexico and Colombia guides.

FAQ
QHow much does a Costa Rica eSIM cost in 2026?
ACosta Rica travel eSIMs start around US$5 for 1 GB and run to roughly US$20–25 for 20 GB over 30 days. For a typical 7–10 day trip, 3–5 GB (about US$9–13) covers maps, WhatsApp, rideshare, and daily uploads. That is far cheaper than US carrier roaming at US$10–15 per day.
QWhich network does a Costa Rica eSIM use?
ATravel eSIMs run on Kölbi (ICE) and Claro, Costa Rica's leading networks. Kölbi has the widest reach into the Central Valley, Arenal, Monteverde, and Guanacaste; coverage thins on remote jungle roads and parts of the Osa Peninsula, so download offline maps for those legs.
QCan I keep my home number in Costa Rica?
AYes. The eSIM is a data-only second line. Keep your home SIM in the phone with data roaming turned off and your number still receives calls, texts, and bank verification codes over Wi-Fi while the eSIM handles cheap local data.
QWhen should I install the Costa Rica eSIM?
AInstall and activate on home Wi-Fi a day before you fly, following the emailed QR code. It connects automatically when you land at Juan Santamaría (SJO) or Liberia (LIR), so you have maps and rideshare working the moment you clear customs.
Bottom line
For Costa Rica in 2026, a Kölbi/Claro-backed eSIM from US$5 is the cheapest, simplest way to stay online — install on Wi-Fi before you fly, keep your home SIM for your number, and land with maps and rideshare ready. Pick 5 GB for a standard week or 10–20 GB if you hotspot a laptop.
