Best eSIM for Costa Rica (2026): Prices, Networks and Which Plan to Buy for San José, Guanacaste and the Osa

The best eSIM for Costa Rica on price is Wayfarro, at every plan size we could compare. A week of unlimited data costs $16 with Wayfarro against $36.50 with Airalo, and 5GB for 30 days costs $12 against $19 with Nomad. Wayfarro's prices come straight from its store; Nomad's and Airalo's were checked in October 2026. Nomad is the one to look at if you want a plan that names Kölbi, the network with the widest rural reach.

Costa Rica is a driving country, and that shapes the plan you need. You'll be on Waze for hours between La Fortuna, Monteverde and the Guanacaste beaches, messaging hosts and shuttle drivers on WhatsApp, and then spending a day or two somewhere with no signal at all. The plan to buy is one sized for the road days, plus a habit of downloading maps before you leave town.

How to read this table: Wayfarro is the cheapest of the three on every row where there's something to compare, and the gap is widest on unlimited plans. Nomad's fixed plans cost more than Wayfarro's at every size. Airalo's Costa Rica page showed only unlimited plans; it also sells fixed-data plans, so check its site for those. Wayfarro is the only one with a 1-day unlimited plan and with 2GB, 50GB and 100GB plans. A dash means the provider doesn't sell that exact plan, or we couldn't confirm its US-dollar price.

Wayfarro's unlimited rows are its Unlimited Lite plans: 1GB a day at full speed, then 512 kbps until the next day. It also sells Unlimited Essential (1GB a day, then 1.25 Mbps) and Unlimited Plus (2GB a day, then 2 Mbps). Seven days costs $19 on Essential and $38 on Plus. Nomad and Airalo don't publish a daily high-speed allowance for their Costa Rica unlimited plans. Nomad says its eSIMs support hotspot.

Which is the best eSIM for Costa Rica for your trip?

Pick by how many days you'll be driving and how remote you're going:

• Long weekend in San José and one beach (3–4 days): 1GB at $5 covers Waze, WhatsApp and a few photos if you lean on hotel Wi-Fi. For a weekend of posting, the 3-day unlimited at $8 is well under Airalo's $19.50.
• One week, the classic loop (Arenal, Monteverde, Manuel Antonio): 5GB at $12 is enough for navigation and messaging. If you'll upload video from every waterfall, the 7-day unlimited at $16 is less than half Airalo's price.
• Ten days, Guanacaste beaches and a surf camp: 10GB at $17 or the 10-day unlimited at $22, both cheaper than Nomad's $25 and $35.
• Two to four weeks, Caribbean side and the Osa: 20GB at $27 covers a month of normal use, and the days in Tortuguero and Corcovado will use almost none of it. For a month of heavy use, the 30-day unlimited is $64 against Airalo's $89.
• Working remotely from Tamarindo or Santa Teresa: 50GB at $56 if you'll hotspot a laptop, or the Plus tier at $154 for 2GB a day before the slowdown.
• A single day between flights: The 1-day unlimited at $5.

Networks and coverage in Costa Rica

The best eSIM for Costa Rica is only as good as its network, and Costa Rica has three: Kölbi, Claro and Liberty. Kölbi is the brand of ICE, the state-owned utility, and is generally credited with the broadest coverage, especially in rural areas. Claro works well in towns and tourist areas and switched on 5G in populated areas in 2025. Liberty, which used to be Movistar, is strong in cities and the main tourist hubs, with 5G expanding in Guanacaste, the Central Pacific and the Northern Zone, and thinner coverage in some rural spots.

Nomad names Kölbi ICE and Liberty for its Costa Rica eSIM, and Airalo names Liberty. Wayfarro's plan page doesn't name its partner network, so if Kölbi specifically matters to you, buy a plan that names it.

What to expect on the ground:

• San José, Alajuela, Heredia: Dense 4G and growing 5G. Fine on every network.
• La Fortuna and Arenal: Good in town. The trails around the volcano are where to expect gaps, so cache the map first.
• Monteverde: Signal in Santa Elena town. Inside the cloud-forest reserves, expect little or none, so download the trail map first.
• Guanacaste (Tamarindo, Nosara, Sámara): Good in the coast towns, where Liberty's 5G is expanding. The dirt roads between them are rural roads, with the gaps that implies.
• Mountain roads: Signal drops on mountain and rural roads, including the climb to Monteverde. Have the route cached in Waze or Google Maps before you set off.
• Tortuguero and the Osa Peninsula: The villages have coverage. No carrier covers the canals, the deep forest or much of the Osa well, and streaming anything from Corcovado National Park isn't realistic.

A local tip that's worth repeating: if one carrier has a dead zone, another sometimes has a tower there, so ask your host which network works at a remote lodge before you count on any of them.

How to set up an eSIM for Costa Rica

Install at home, turn it on when you land. It takes about two minutes:

1. Check your phone isn't carrier-locked and supports eSIM. iPhone XS and later, Google Pixel 3 and later, and most recent Samsung Galaxy phones do.
2. Install over Wi-Fi before you fly. Scan the QR code or use the one-tap install link. Step-by-step install guide.
3. Label it "Costa Rica" so it's easy to pick in settings.
4. When you land, set the Costa Rica eSIM as your mobile-data line and turn on Data Roaming for it. Travel eSIMs technically roam, so data won't connect without this setting.
5. Keep your home SIM on for calls and texts (turn its data roaming off to avoid charges) so you still get bank verification codes.

With Wayfarro, your plan's validity starts when the eSIM first connects in Costa Rica, not when you install it. Buying a week before you fly costs you nothing.

Arriving at SJO or Liberia: what's changed

Buying a local SIM on arrival is harder than it used to be. Juan Santamaría International Airport (SJO) sits in Alajuela, about 20 km northwest of downtown San José, and handled around 6.7 million passengers in 2025. The carrier desks there and at Guanacaste Airport in Liberia (LIR) have closed or open irregularly, and the small airport shops may or may not stock SIMs. A prepaid line also has to be registered to an ID, which for visitors means a passport in a carrier store; the nearest cluster to SJO is City Mall in Alajuela, five minutes away, and in Liberia all three carriers have stores downtown.

That's the practical case for an eSIM here. You install it on your sofa, it connects as the plane doors open, and your home SIM stays in the phone. From SJO there's a 24-hour bus into San José roughly every 10 minutes during working hours, and licensed taxis take both colones and US dollars, so you can be on Waze in the taxi rather than in a queue.

Two more habits that save data and trouble: turn off automatic app updates and photo backups on mobile data, and save big uploads for hotel Wi-Fi. A 5GB plan goes a long way when the phone isn't quietly syncing a day of beach photos over 4G.

Waze, WhatsApp and the apps you'll actually use

Waze is the navigation app of choice in Costa Rica. It's popular enough that Kölbi's own tourist SIM bundles extra data for Waze and WhatsApp. Addresses here are often descriptions ("200 metres south of the church"), so hosts send a pin on WhatsApp and you follow it. Both apps are light on data, but they need a connection to recalculate when a river crossing or a landslide closes the road, which is exactly when offline maps earn their keep.

If you're crossing into Panama for Bocas del Toro or coming down from Nicaragua, a Costa Rica plan stops at the border. The Central America eSIM covers Mexico, Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama on one eSIM.

Bottom line

Wayfarro is the best eSIM for Costa Rica on price in this comparison, cheapest at every size, and by a wide margin on unlimited plans. Nomad costs more but names Kölbi, which matters if you're heading somewhere remote. Airalo's unlimited plans on Liberty cost roughly double Wayfarro's for the same days. Whichever you choose, download your maps before you leave the city. See Wayfarro's Costa Rica eSIM plans, or compare the wider region in our best eSIM for Latin America guide.
