eSIM for Costa Rica

Costa Rica moves at the pace of a sloth and rewards you for slowing down too. You'll zipline through Monteverde's cloud forest, soak in the Tabacon hot springs below Arenal, surf Playa Guiones in Nosara, and count quetzals in San Gerardo de Dota. Uber works in San Jose and most of the Central Valley, and data is handy for booking Interbus shuttles, checking surf reports on Surfline, and translating menus full of casados and gallo pinto.

How to install your Costa Rica eSIM in 3 steps

Setting up your eSIM before you fly means you can land in San José or Liberia with data already active, no counter queue required.

1. Buy and receive your QR code. Pick a data plan sized to your trip and get the eSIM QR code delivered straight to your email or account, ready to install before you leave home.
2. Install the eSIM profile. On a compatible phone, open your mobile network settings, choose to add a new eSIM or cellular plan, and scan the QR code (or enter the manual install details if scanning isn't possible). This works over any Wi-Fi connection, so it's done before you even pack.
3. Land and switch on data roaming. Once you touch down, activate the new eSIM line and enable data roaming for it. Your phone should pick up a Kölbi, Liberty or Claro signal shortly afterwards and you're ready to go.

Coverage in Costa Rica

Costa Rica's mobile network is shared between three operators: Kölbi (run by state operator ICE), Liberty and Claro. Kölbi's 4G footprint reaches across much of the country and is generally the strongest option in rural areas and close to national park entrances. Liberty and Claro both have broad 4G reach and are strongest across the more populated Central Valley and coastal towns. All three run nationwide 3G/4G, while 5G is still a limited rollout rather than a nationwide standard.

5G has gone live in parts of the Central Valley - San José, Alajuela, Heredia and Cartago - as well as in Guanacaste, the Central Pacific and the Northern Zone, with Liberty and Claro leading the rollout. Coverage there is best described as urban and suburban rather than continuous, so don't expect 5G once you're off the main roads.

Tourist corridors are generally well served: the Pan-American Highway and the routes between major towns carry a reliable signal, and popular bases like La Fortuna/Arenal, Tamarindo, Manuel Antonio and Puerto Viejo all have decent 4G for day-to-day use. The gaps show up in eco-tourism territory - deep inside Corcovado, Tortuguero and the Monteverde cloud forest, signal drops off quickly beyond the entrances, mountain roads can lose a stable connection for stretches, and remote parts of the Osa Peninsula and smaller rural villages may have no tower coverage at all. Tortuguero, reachable only by boat or small plane, is a particular case where you should expect very limited signal throughout your stay.

How much data do you actually need?

Match your Costa Rica eSIM plan to how you'll actually use your phone, rather than buying the biggest bundle out of caution.

Usage level	Typical daily use	Suggested plan
Light - maps, messaging, occasional browsing	around 300MB/day	1GB (7-day) for a short trip, or 3GB (30-day) for a full month
Moderate - social media, music streaming, video calls	around 750MB/day	10GB (30-day), comfortable for two to three weeks
Heavy - video streaming, hotspot use, frequent calls	1.5GB/day or more	20GB (30-day), built for longer stays or several devices

eSIM vs. roaming vs. a local SIM in Costa Rica

How you get online depends on how long you're staying and how much you value avoiding paperwork.

	eSIM	Home network roaming	Local prepaid SIM
Setup	Install online before you travel, no registration needed	Works automatically on arrival, no setup	Bought at airports, operator stores or convenience shops; passport required, plus mandatory SUTEL registration (only takes a few minutes)
Typical cost	Fixed price known in advance, from £2.75 for 1GB	Varies widely: some US carriers charge from around £4/day for a small allowance, others £8-£9+/day, or monthly roaming add-ons from around £23 up to £75+ depending on data allowance; UK/EU providers often charge similar daily rates or passes from around £8	Local retail price for the SIM itself
Watch out for	None beyond your chosen plan	Pay-as-you-go rates without a bundle can run around £1-£2 per minute of calls plus steep per-MB data charges	Maximum five prepaid SIMs allowed per passport
Best for	Most visitors who want data working on arrival	Very short trips where convenience matters more than cost	Travellers settling in for an extended stay who also want a local number

Practical connectivity tips for Costa Rica

Costa Rica is one of the region's leading digital-nomad destinations, and it shows: San José and other major cities have fast fibre internet and a growing number of coworking spaces, with hubs in Tamarindo and Santa Teresa popular with remote workers who pair a laptop connection with a mobile eSIM as backup.

Download offline maps before heading into Corcovado, Tortuguero or the Monteverde cloud forest - signal thins out fast once you're past the entrance, and Tortuguero in particular is only reachable by boat or small plane, so don't rely on being able to call ahead once you're there. Mountain roads can also drop your connection for a stretch even on a main route, so let anyone expecting to hear from you know that gaps are normal in these areas.

If something urgent comes up, 911 is the verified nationwide emergency number for police, fire and medical help, with bilingual operators available around the clock; the fire brigade, Red Cross and police also have their own direct lines (118, 128 and 117) as alternatives. Keep your accommodation's address written down, since data can be patchy right at the point you need it most in remote areas.
