Summary

The best Costa Rica eSIM for 2026 gives you Claro data from a few dollars, 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.

Hotspot and tethering are allowed on every plan we sell. Plans are data-only unless the plan page states otherwise — only selected plans carry calls or SMS. IP breakout is where your traffic exits the network, which is not always the country you are visiting. Prices and networks are read from the same catalogue that powers our machine-readable pricing file, so this table cannot go stale against checkout.

Why an eSIM beats roaming in Costa Rica

Costa Rica's mobile market is led by Kölbi(the ICE state carrier), which has the deepest rural footprint but supplies no travel eSIM brand — you can only get it on a local SIM bought in-store with your passport. YonoSIM routes on Claro, which covers San José, the Central Valley, Arenal/La Fortuna, Monteverde, Manuel Antonio, and the Guanacaste beaches. You get local-network signal — 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.

Networks are each brand's own published figure. Prices, plan counts, and data sizes via esimDB, checked 20 August 2026. Holafly publishes neither a per-country carrier nor plans on esimDB, so it cannot be scored on price or range here. Plan range is counted in distinct data sizes, not plan count.

Which one to pick

  • Coverage: YonoSIM and Airalo publish the same number of networks here (1); ours are Claro (4G).
  • Cheapest data is Nomad at $1.55/GB — YonoSIM is $3.20. If price is the only thing you are optimising, buy theirs.
  • Want an unusual data size? Nomad & Saily offer the most granular ladder (8 distinct sizes).
  • Want the data back if you don’t use it? YonoSIM refunds unused data automatically after 30 days; the others require you to ask. Check each brand’s current terms before you buy.

FAQ

QHow much does a Costa Rica eSIM cost in 2026?

ACosta Rica travel eSIMs start at a few dollars 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$4–13) 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?

AKölbi (the ICE state carrier) has the widest reach into the Central Valley, Arenal, Monteverde, and Guanacaste, but it supplies no travel eSIM brand — you can only get it on a local SIM bought in-store with your passport. YonoSIM routes on Claro, which is strong in San José, the Central Valley, and the main tourist towns. 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 Claro-backed eSIM 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.
