Best SIM and eSIM for Costa Rica: data plans, Wi-Fi and phone tips
For most trips, an eSIM you install before landing is the best option for Costa Rica: you get data the moment you clear SJO, no shop queue and no passport errand. Buy a local Kölbi, Claro or Liberty SIM only if you need a +506 number for calls or a longer stay. Coverage thins in Osa, Tortuguero and some mountain valleys, so download offline maps either way.

Summary: eSIM vs local SIM vs roaming
Three workable routes. Pick by how long you stay, whether you need a Costa Rican phone number, and how much you care about setting things up before you fly.
| Option | Best for | Setup | Cost (2026 estimate) | Watch out for |
|---|---|---|---|---|
| Travel eSIM | Trips of 3–14 days, arriving late or on a tight transfer | Buy online, scan QR, activate on landing | US$5–30 for 1–10 GB (check) | Data-only: no +506 number; check your phone is eSIM-capable and unlocked |
| Local prepaid SIM | Stays over two weeks, need a local number for calls or deliveries | Buy at SJO or an operator shop; passport required | Plan-dependent; check current prepaid bundles | Shop queues at the airport; top-ups and registration in Spanish |
| Home-carrier roaming | Short trips, business travellers who need their own number | Nothing to do | Usually the most expensive per GB (check your plan) | Daily caps and throttling; check before you rely on it |
Step by step
Before you fly: confirm your phone is unlocked and supports eSIM (most recent iPhones, Samsung Galaxy and Pixel models do; check your exact model). Buy the eSIM for the days you actually need, install it at home on Wi-Fi, and leave it switched off until you land. Screenshot the QR code and the activation instructions in case you have no data on arrival.
On landing at Juan Santamaría (SJO) or Daniel Oduber (LIR): turn the eSIM line on and disable data roaming on your home line so you are not billed for background traffic. If you prefer a local SIM, Kölbi, Claro and Liberty sell prepaid SIMs at SJO and in towns, and you will need your passport for registration.
In the country: keep your home number active for bank and airline codes if you need it, and use the eSIM for maps and messaging. WhatsApp is how shuttle drivers, tour operators and hosts usually reach you, so make sure it is installed and your number is reachable.
Before remote legs: download offline maps for Osa, Tortuguero and any mountain valley you plan to cross, and save your accommodation's phone number and coordinates. Signal can drop for long stretches on those routes.
Coverage and Wi-Fi
Coverage is good along the Central Valley, the Guanacaste beaches and around La Fortuna, and it thins in the Osa Peninsula, Tortuguero and some mountain valleys. That is a coverage gap, not a plan problem, so no eSIM or local SIM fixes it — plan offline maps and downloaded tickets instead.
Wi-Fi is common in hotels, hostels, cafés and many sodas, but speed and reliability vary by area and by how many guests are online. Treat it as a bonus rather than your main connection: use it for big uploads and video calls, and keep mobile data for maps and messages on the road.
| Area | Mobile data | Wi-Fi |
|---|---|---|
| San José and Central Valley | Good | Widely available |
| Guanacaste beaches | Good in towns and resorts | Common in hotels and cafés |
| La Fortuna / Arenal | Good | Common in lodges and town |
| Osa Peninsula | Thin, gaps on the road | Limited outside lodges (check) |
| Tortuguero | Thin | Usually lodge-only (check) |
| Mountain valleys | Patchy | Varies by property (check) |
Notes
Costa Rica uses the +506 country code with 8-digit numbers. Cards and contactless payments are accepted almost everywhere, and SINPE Móvil is the local transfer app that Costa Ricans use between themselves — as a visitor you will rarely need it.
For driving, Waze is the standard app in Costa Rica, and Uber works in the San José area; WhatsApp is the default channel for shuttles and tours. If you are buying park tickets, SINAC's online services are the official route, so make sure you have data or Wi-Fi when you book.
Two practical cautions. First, eSIMs are data-only: if you need a Costa Rican number for calls, take a local prepaid SIM instead. Second, if you decline the rental company's collision cover, a deposit of US$1,000–5,000 is blocked on a credit card — check your limit before you travel.
FAQ
Questions people ask
What is the best eSIM for Costa Rica?
Any reputable travel eSIM that covers Costa Rica and fits your trip length works; the differences are price per GB, validity and whether support is in your language. Buy before you fly, install on Wi-Fi, and activate on landing at SJO. Expect US$5–30 for 1–10 GB (2026 estimate, check current plans).
Does my phone work in Costa Rica?
Yes, if it is unlocked and supports the local networks. Most recent iPhones, Samsung Galaxy and Pixel models do, and most also support eSIM. Check your exact model before buying, and remember that coverage thins in Osa, Tortuguero and some mountain valleys.
Is Wi-Fi easy to find in Costa Rica?
Hotels, hostels, cafés and many sodas offer Wi-Fi, and it is common in tourist areas. Speed and reliability vary, and remote lodges may be the only option in places like Tortuguero or the Osa. Treat Wi-Fi as a bonus and keep mobile data for maps and messages.
Can I buy a SIM card at San José airport?
Kölbi, Claro and Liberty sell prepaid SIMs at SJO and in towns, and you need your passport for registration. Airport shops can have queues at peak arrival times, so an eSIM bought in advance is faster if you only need data.
Do I need a Costa Rican phone number?
Only if you need to make local calls, receive verification codes or deal with deliveries. For maps, WhatsApp and bookings, a data-only eSIM is enough, and most shuttle and tour operators contact you through WhatsApp.
How much data should I buy for Costa Rica?
For a one-week trip with maps, messaging and light browsing, 3–5 GB is usually enough; add more if you stream video or work remotely. Download offline maps for remote areas so a coverage gap does not eat your plan.
