Quick verdict: which Costa Rica eSIM to buy

Costa Rica coverage: what to expect outside San José
Kolbi (the state telecom, ICE) and Claro provide the widest coverage across Costa Rica's varied terrain. San José and the Central Valley have solid 4G/5G. Coverage thins in specific pockets worth knowing about before you go.
- Arenal Volcano (La Fortuna): solid 4G in town and at the main viewpoints — hot springs resorts and hanging bridge parks are all covered.
- Monteverde cloud forest: 4G in Santa Elena town and at the reserve entrance; the hanging bridges trails themselves have patchy 3G/4G.
- Manuel Antonio: 4G at the town and national park entrance; interior trails vary with proximity to the coast.
- Nicoya Peninsula (Tamarindo, Nosara, Santa Teresa): 4G on main roads and in town centers; more remote beach-access tracks may drop to 3G.
- Corcovado National Park (Osa Peninsula): 4G at Puerto Jiménez gateway town; the park interior is largely offline — download maps first.
- Tortuguero: 4G in the village (boat-access only); the turtle-nesting beach itself is offline.
Is it worth getting an eSIM for Costa Rica, or buying a local SIM?
For most travelers, yes. Costa Rica doesn't have the same airport tourist-SIM culture as somewhere like Thailand — Kolbi and Claro counters exist at Juan Santamaría (SJO) but queues and passport requirements make it slower than installing an eSIM on Wi-Fi before you fly. An eSIM also means you land already connected for your rental car GPS or ride-share pickup.
Frequently asked questions
What is the best eSIM for Costa Rica?
For most trips, a fixed-data Flysimio plan (5–10 GB) offers the best value — Costa Rica's networks are fast enough that unlimited plans are rarely necessary. Flysimio's 20 GB tier ($85.00) even undercuts Airalo's unlimited 30-day plan ($89.00) for travelers who want plenty of headroom without paying an unlimited premium.
Does the eSIM work at Arenal Volcano and La Fortuna?
Yes. La Fortuna town and the main Arenal viewpoints have solid 4G on Kolbi and Claro. Hot springs resorts and hanging bridge parks near La Fortuna are all covered.
Is there coverage in Monteverde cloud forest?
Yes in Santa Elena town and at the Monteverde Cloud Forest Reserve entrance. The hanging bridges trails themselves have patchy 3G/4G — download offline maps before entering.
How much data do I need for two weeks in Costa Rica?
For typical use — maps, messaging, and social media — 5 GB is comfortable for one to two weeks. If you're covering more ground (Arenal, Monteverde, Manuel Antonio, and the Nicoya beaches) or streaming occasionally, size up to 10 GB.
Does the eSIM work at Manuel Antonio beach?
Yes. Manuel Antonio town and the national park entrance have 4G. Interior trail coverage varies with proximity to the coast.
Is Costa Rica eSIM cheaper than Airalo?
For fixed-data plans, yes — Flysimio is typically cheaper per GB. If you specifically want unlimited data, compare Flysimio's 20 GB tier ($85.00) against Airalo's unlimited 30-day plan ($89.00); the gap is small, so pick based on whether you'll actually use more than 20 GB.
Do I need to activate before I fly to Costa Rica?
No. You have six months from purchase to activate — the validity period only starts counting down when your eSIM first connects to a network in Costa Rica.
