Networks and coverage in Costa Rica
Costa Rica-specific plans in the catalog run on Claro (10 plans). A further 11 multi-country plans also cover Costa Rica — useful when the trip crosses borders, and shown in the table above with their country count. Each plan's network is stated on the plans page before checkout.
How we picked the best eSIM for Costa Rica
- Price per gigabyte on the plan sizes travellers actually buy (3–20GB over 7–30 days), from live catalog prices — not the headline "from" price.
- Network: which local operator the plan connects to, taken from the plan data, not marketing copy.
- Fit for the trip: validity that outlasts the stay, coverage that matches the route (single-country versus multi-country).
- No surprises: prepaid, no contract, no roaming fees, hotspot allowed, validity that starts on first connection rather than at purchase.
We do not quote other providers' prices on this page because they change without notice; compare on the same four points and the answer is usually clear.
Travel tips: staying connected in Costa Rica
- Waze is the national navigation app — Costa Rican drivers, hotels and tour operators all give directions in Waze pins, and it needs live data.
- Manuel Antonio and Corcovado parks now require advance online tickets — book before travel days; park-gate connectivity can't be relied on.
- Monteverde's cloud-forest roads and the Osa Peninsula have real dead zones on every network — download offline maps before leaving San José.
Costa Rica eSIM — frequently asked questions
Which networks do Costa Rica eSIMs use?
esimbloom's Costa Rica-only plans connect to Claro; the South America multi-country plans that list Costa Rica roam onto their own partner network. Each plan states its network on the plans page before checkout.
Do I need data for national park visits?
Yes for booking — Manuel Antonio and others sell timed tickets online only. Book on data the day before; signal at remote park entrances is unreliable.
Is there signal in Monteverde and on the Osa Peninsula?
Monteverde town has coverage with gaps on forest roads; the Osa (Corcovado area) is Costa Rica's emptiest coverage map — treat Drake Bay legs as mostly offline.
How much does an eSIM for Costa Rica cost?
esimbloom Costa Rica plans start from $1.92 for 500MB over 1 day, with 21 plans up to 20GB. There are no roaming fees and no contracts — you pay once for the plan you pick.
Is there an unlimited data eSIM for Costa Rica?
Not at the moment. The largest Costa Rica plan in the catalog is 20GB for 30 days at $81.60 ($4.08/GB) with full-speed data and hotspot — for most travellers that beats a throttled 'unlimited' plan.
When does a Costa Rica eSIM activate — should I install it before I travel?
Install it at home on Wi-Fi as soon as the QR code arrives; validity only starts when the eSIM first connects to a network in Costa Rica. Keep the line switched off until you land, then enable it and turn on data roaming for that line only.
