Staying connected in Costa Rica is easy once you know the options — and choosing the right one matters more than you'd think. Between physical SIM cards, travel eSIMs and your home carrier's roaming, the difference can be $60 on your trip budget and hours of hassle at the airport.
This guide covers everything: the carriers that actually operate in Costa Rica, where to buy a SIM card (including the Claro stand at San José airport), what coverage is really like by region, and the newer option most travelers now prefer — a travel eSIM you install before your flight.
Cellular Carriers in Costa Rica (2026)
Costa Rica has three main mobile carriers:
- Kölbi (ICE) — the state-owned carrier with by far the widest coverage, including rural areas, cloud forests and peninsulas where other networks drop out. If you're heading off the beaten path, Kölbi is the network that reaches.
- Claro — strong 4G speeds and competitive prices, with a SIM stand right at San José International Airport (SJO). The go-to for most arriving travelers.
- Liberty — absorbed the old Movistar network and is strong in the Central Valley, San José and the main tourist zones of Guanacaste and the central Pacific.
A note if you've read older guides: Movistar no longer exists as a brand in Costa Rica — Liberty took over its network. Articles still listing Movistar, Tuyo Móvil or "five carriers" are outdated.
eSIM for Costa Rica: the Easiest Option for Most Travelers
An eSIM is a digital SIM card: instead of queueing at a kiosk with your passport, you buy online, scan a QR code, and your phone is connected — often before you even land. For Costa Rica specifically, the travel eSIM we recommend is Holafly's Costa Rica eSIM, and it has become the default choice for most of our travelers.
Why it works well here:
- Unlimited data — no counting gigabytes, no running out mid-trip. Plans run on local networks (Claro) so coverage matches a physical SIM
- Buy before you fly — set it up at home on hotel Wi-Fi; it activates when you land in Costa Rica
- Flexible duration — choose anywhere from a few days to 90 days to match your trip, and the per-day price drops the longer you stay
- Keeps your WhatsApp number — your regular SIM stays in the phone, so calls and texts to your normal number still work. This matters in Costa Rica, where everything runs on WhatsApp — tours, shuttle drivers, hotels, restaurants
- Hotspot sharing included (about 1 GB/day) — useful for a laptop or a travel partner's phone
Pricing varies with trip length, but as a reference: shorter plans run around $19–35, and a full month lands in the $50–60 range — comparable to or cheaper than a month of local prepaid data, with zero effort. Check current Holafly Costa Rica prices and plans here.
Honest limitations: an eSIM is data-only — it doesn't come with a Costa Rican phone number for local calls (WhatsApp covers 95% of what travelers need anyway). Hotspot sharing is capped. And your phone must be carrier-unlocked and eSIM-compatible (iPhone XS/XR or newer, most recent Android flagships).
eSIM vs Physical SIM Card: Which Should You Choose?
Both get you online. The right choice depends on your trip:
- Choose an eSIM if: you want zero hassle, you land outside business hours, you're only using data and WhatsApp, or you're visiting multiple destinations and don't want to think about it again after setup. Get the Holafly Costa Rica eSIM here.
- Choose a physical SIM if: you're staying a month or more, you need a local Costa Rican phone number (rare for travelers — for example, if local businesses will call you), your phone doesn't support eSIM, or you're absolutely minimizing cost on a long stay.
For a one- to three-week vacation — which is most of our readers — the eSIM wins on convenience and the price gap has narrowed to nearly nothing.
Physical SIM Cards: Where and How to Buy
If you go the physical SIM route, here's what to expect.
Option 1: Claro at San José International Airport (SJO)
The easiest physical option. After immigration and baggage claim, there's a Claro stand — historically the only SIM vendor inside the airport. Bring your passport; plans for a month of data (with unlimited WhatsApp) have typically run around $20, card or cash. Staff install and activate the SIM for you on the spot.
To top up later, look for any shop advertising "recargas Claro" — supermarkets, kiosks and phone accessory stores everywhere. Give them your number and the amount, pay cash, done.
Option 2: Kölbi, Claro or Liberty stores in town
In Quepos and every sizable town, you'll find carrier stores and kiosks with visible signage. Bring your passport. Kölbi is the one to ask for if your itinerary includes remote areas — its rural coverage is the reason it survives as the state carrier.
What you need
- Your passport (required for registration — Costa Rica requires ID for SIM purchases)
- Cash or card (small vendors may prefer cash)
- An unlocked GSM phone (if bought in the US, verify it's unlocked before traveling)
Coverage in Costa Rica: What to Expect by Region
Coverage is good where tourists go and thinner where almost nobody goes. A realistic map:
- San José and the Central Valley: excellent coverage on all networks, 5G available in parts of the metro area
- Pacific coast (Guanacaste, Manuel Antonio, Uvita, Dominical): good coverage in towns and most beaches; some gaps on remote stretches
- Monteverde and the northern mountains: good in town, weak on back roads
- Caribbean (Puerto Viejo, Cahuita): decent in town, inconsistent south toward Manzanillo
- Osa Peninsula and Drake Bay: the thinnest coverage in the country — treat connectivity as a bonus, download offline maps first
If remote destinations are on your itinerary, Kölbi has the edge. For the standard tourist circuit, any of the three networks — or a travel eSIM — will serve you fine.
Tips for Staying Connected in Costa Rica
- Download offline Google Maps for your destinations before heading into rural areas — the app works with GPS even without signal. Maps.me is a good offline alternative too
- Use WhatsApp for everything. Tours, shuttle drivers, hotels, restaurants — Costa Rica runs on WhatsApp, and messages go through even on weak data
- Save hotel Wi-Fi for heavy lifting. Streaming and big uploads on Wi-Fi, maps and messages on mobile data
- Bookmark your confirmations offline. Shuttles, tours and park tickets — screenshot or save PDFs in case signal drops exactly when you need them
- Check your home carrier's roaming price first. Some US carriers include free Mexico/Canada but charge $10+/day for Central America — an eSIM is almost always cheaper than that

Frequently Asked Questions
For most trips, yes. You install it before flying, it activates when you land, and unlimited data means you never think about top-ups. The main trade-off: eSIMs are data-only, with no local phone number — but since nearly everything in Costa Rica runs on WhatsApp, that rarely matters.
Kölbi (state-owned ICE) has the widest coverage, especially in rural and mountainous areas. Claro and Liberty are strong in cities and tourist zones. For the typical tourist circuit — San José, La Fortuna, Manuel Antonio, Guanacaste — all three work well.
Yes. Claro operates a stand inside SJO after immigration and baggage claim. Bring your passport; plans with data and unlimited WhatsApp have typically cost around $20 for a month. Note it's the only SIM vendor in the airport.
If it's carrier-unlocked and supports GSM 850/1800 MHz (virtually all smartphones from the last several years), yes. For eSIMs, you need an eSIM-compatible device — iPhone XS/XR or newer, or a recent Android flagship.
Local prepaid SIMs with data have typically run around $20/month including unlimited WhatsApp. Travel eSIMs for Costa Rica range from about $19 for a short trip to $50–60 for a month of unlimited data. Roaming through your home carrier is usually the most expensive option.
Almost never. WhatsApp is the standard way tours, shuttles, hotels and restaurants communicate with travelers — and WhatsApp works over data with your existing number.
5G rollout is underway, led by Liberty, Claro and Kölbi in parts of San José and other urban centers. Don't plan around it — 4G/LTE is widespread and plenty fast for maps, WhatsApp and streaming.
Final Thoughts: Staying Connected in Costa Rica
For most travelers in 2026, the cleanest setup is a Holafly travel eSIM installed the night before your flight: unlimited data, your own WhatsApp number untouched, and zero paperwork. If you're staying long-term or heading deep off-grid, add a local Kölbi SIM for its rural reach.
