Summary
For a Costa Rica mission trip, a Kölbi/Claro-backed travel eSIM from ~US$5 gives your team local data across San José, the Central Valley, and the coasts while your US number stays live for family and emergencies. Costa Rica is a common first-time short-term mission field, and the US State Department advises travelers to stay reachable — this setup does that for a fraction of US roaming.
Connectivity for a Costa Rica mission team
Costa Rica's mobile networks are led by Kölbi, the mobile brand of the state utility ICE, alongside Claro and Liberty. Kölbi has the deepest rural footprint, covering most of the Central Valley, Guanacaste, and the Caribbean lowlands. A travel eSIM rides those networks, so your team gets the same local signal a Costa Rican phone would use — far more reliable in remote ministry areas than a US roaming partner.
Keep your US SIM in the phone with roaming off, and add the Costa Rica eSIM as the data line. Your US number still rings for a worried parent or your sending church; all data — WhatsApp, maps, photo uploads — runs on the cheap local plan. See the mission-trip eSIM hub for the full team setup.

FAQ
QHow much data does a Costa Rica mission trip need?
AFor a 7–10 day trip, 3–5 GB covers WhatsApp coordination, offline map downloads, photos, and a nightly check-in home. Teams that livestream or hotspot a laptop for reports should pick 10 GB. Plans start at ~US$5 and run on Kölbi (ICE) or Claro, Costa Rica's strongest networks.
QWhich carrier has the best coverage in rural Costa Rica?
AKölbi (state carrier ICE) has the widest reach, including much of the Central Valley, Guanacaste, and the Caribbean side, with Claro strong in towns. A travel eSIM connects to whichever local network has signal. Coverage thins on remote jungle and mountain routes, so download offline maps for your specific ministry sites before you go.
QCan I keep my US number while serving in Costa Rica?
AYes. The eSIM is a second line for data only. Keep your US carrier SIM in the phone with data roaming turned off, and your US number still receives calls, texts, and bank verification codes over Wi-Fi or your home line while the eSIM handles cheap local data.
QShould the team leader buy all the eSIMs?
AIt is the simplest approach. One leader buys a Costa Rica plan per volunteer, emails each person their QR code, and everyone installs on home Wi-Fi before the flight. No one hunts for a SIM kiosk after landing at Juan Santamaría (SJO) or Liberia (LIR) airport.
Bottom line
For a Costa Rica mission team, buy a Kölbi/Claro-backed eSIM per volunteer (from US$5), install on Wi-Fi before you fly, and keep your US SIM in the phone for your number. Your team lands coordinated on WhatsApp, families can reach you, and the money you save on roaming goes to the work instead. See the full mission-trip eSIM guide for the team checklist.
