その他Most trips to Costa Rica start at San José or Liberia and quickly head out to Arenal, Monteverde, Manuel Antonio or the Guanacaste beaches. That usually means a rental car, a navigation app and a string of lodge bookings, all of which depend on data. An eSIM Costa Rica gets you online the moment you clear customs, with no airport queue and no roaming pass. Purchase the Costa Rica eSIM online, scan the QR code before you fly, and it connects to Telefonica Costa Rica automatically while your own number stays active on your primary SIM.
The plan connects to Telefonica Costa Rica, one of the country’s main mobile operators. Coverage is strong in San José and the Central Valley, in Liberia and along the Pacific beach towns from Tamarindo to Jacó and Quepos, and on the main highways between them. In the cloud forest around Monteverde, inside the national parks, on the Osa Peninsula and on the Caribbean side around Puerto Viejo, signal is weaker and can drop out in valleys or under dense canopy. That is true of every network here, so plan for offline moments on hikes and save your route before you leave a town.
The Costa Rica eSIM prepaid data plan starts from $4 for 1GB, and you can also choose 2GB, 3GB, 5GB, 10GB, 15GB or 20GB. Validity matches the size: 7 days for 1GB, 10 days for 2GB, 14 days for 3GB, 21 days for 5GB, and 30 days for 10GB, 15GB and 20GB. A week of surfing and sunsets in one beach town needs little more than 3GB. A two-week road trip with constant navigation, lodge check-ins and wildlife photos going to the cloud is happier at 5GB to 10GB, and a longer stay with a laptop tethered to the phone belongs on 15GB or 20GB. Your validity starts only when the device first joins a supported network in Costa Rica, so install early with no wasted days.
Driving is the norm here, and a live navigation app is far better than paper maps for unmarked turns, river crossings and roadworks. Lodges and eco-hotels often have Wi-Fi only in the reception area, and it is shared with everyone, so your own data is the reliable option for video calls home. Tour operators, shuttle companies and small hotels reply on WhatsApp, which keeps working on your primary SIM. Weather changes fast on both coasts, and a quick radar check before a hike or a boat trip is worth the few megabytes.
Want to phone a lodge in Drake Bay, call the rental company about a flat tire, or receive SMS verification codes on the road? Add a voice-minutes bundle (+100, +200 or +300 minutes) and the eSIM Costa Rica comes with a dedicated international phone number, US +1 or UK +44, for calls and SMS. Data-only plans do not include calling, but messaging apps continue to work as normal.
Transparent pricing paid once, instant delivery by email, Telefonica Costa Rica coverage, hotspot support and an optional real phone number. Works with carrier-unlocked eSIM phones including iPhone 11 and later, Samsung Galaxy S20 and later, and Google Pixel.

Everything worked well and seamless. The coverage in some rural areas was poor, which is why I selected 4 stars.
