Kolbi offers the state operator with the widest reach including rural and coastal areas.
Costa Rica has dependable 4G across San Jose, the Central Valley and the main tourist regions, with 5G beginning to appear in the largest centres. Kolbi carries the widest coverage, including most of the popular Pacific and Caribbean coasts and the volcano regions. The realistic weak spots are the dense rainforest interior, remote national parks such as Corcovado, and the more isolated beach and mountain roads, where signal thins between towns. For the main tourist routes, connectivity is reliable.
Typical local SIM: $10-25. Usually sold at Kolbi stores, supermarkets and pharmacies; airport counters at San Jose and Liberia. Costa Rican SIMs are easy to buy at the airport with a passport, but for a short eco trip a travel eSIM avoids the queue and works the moment you land. Remember that remote national parks have little signal on any network.
For the typical one to two week nature trip a travel eSIM is the easiest choice. For a long stay a local Kolbi SIM is cheaper per gigabyte.

The decision section compares the practical trade-offs. A travel eSIM is usually simpler for a short visit; a local SIM can make sense when you need a local number, longer service or local pricing. Check the current conditions before deciding.
