Where to buy a SIM card at Costa Rica airports

Claro at Guanacaste Airport (LIR)
Guanacaste Airport, officially Daniel Oduber Quirós International Airport, includes Claro in its online list of terminal stores. This is the strongest official evidence of an airport mobile operator at either of Costa Rica’s two main international gateways.
Important details remain unpublished. The directory does not state whether the Claro outlet is before or after security, whether arriving passengers can reach it after customs, or what hours it follows. It also does not publish tourist packages, SIM-card fees, activation charges, accepted payment methods or a complete airport price.
Treat the counter as a possible convenience rather than a guaranteed arrival solution. Ask the employee to explain the complete amount before payment, including the physical SIM, package balance and any activation or retailer fee. Also confirm how much data is included, when it expires and whether the package contains national calls or SMS.
Airport staff may be able to install and test the SIM, but activation assistance is not officially promised. Your phone must be unlocked and support a removable SIM for a physical card.
Juan Santamaría International Airport (SJO)
SJO’s official shopping directory does not currently identify a Claro, Liberty or kölbi operator counter. It lists duty-free, souvenir, pharmacy, technology and convenience businesses, including an IMAS store between immigration and baggage claim, but none is presented as a verified mobile-SIM seller.
Some general airport retailers may occasionally carry prepaid products, but this cannot be treated as reliable availability. A shop selling chargers, adapters or other technology does not necessarily sell registered Costa Rican SIM cards.
Passengers landing at SJO should therefore avoid planning around an airport purchase unless they receive current confirmation directly from the airport or operator. Use airport WiFi to contact your accommodation or driver, then buy from an official city store if you require a local number.
Airport SIM packages and current prices
Costa Rican operators publish domestic prepaid tariffs, but an official tariff is not automatically the amount charged at an airport. An airport retailer can add a physical-card cost, activation service or dealer margin.
The clearest current tourist-oriented offer is the kölbi SIM Turista. The official published tariff checked on July 26, 2026 is ₡12,095, approximately US$27 using a recent reference rate of about ₡455 per US dollar. It includes 5GB of general internet, 5GB for selected apps, 100 minutes for national calls and 30 SMS.
That is an official operator price, not a verified SJO or LIR airport total. There is no reliable evidence that the tourist SIM is sold at either terminal for ₡12,095. Airport stock, card fees and retailer charges could differ.
Claro’s LIR packages and prices are not published by the airport. Current airport price not reliably published.
Before paying for any physical SIM, request a written or screen-displayed breakdown covering:
-
The SIM or starter-card charge.
-
The selected prepaid package.
-
Any activation or service fee.
-
The total amount payable.
-
The package expiration date.
Do not assume a low advertised recharge or add-on price includes a new SIM. Many prepaid offers are designed for customers who already have an active Costa Rican number.
Registration, activation and payment
Costa Rican prepaid telephone lines must be registered to their users. SUTEL, the national telecom regulator, provides a prepaid-line registration service and directs users to register their personal details.
Bring your original passport when buying a physical tourist SIM. The seller may need to record your identity details before the line becomes fully usable. Purchasing an unregistered card from an informal seller can create activation problems later.
Ask staff to complete these checks before you leave:
-
Confirm that mobile data works with WiFi switched off.
-
Make a test call when the package includes national minutes.
-
Check the remaining balance and package expiration.
-
Confirm the Costa Rican telephone number.
-
Verify that the line has been registered correctly.
Payment information is not reliably published for the LIR Claro outlet. Carry a payment card and some Costa Rican colones rather than relying exclusively on foreign cash. The merchant’s exchange rate can differ from the banking reference rate when paying in US dollars.
A Roafly eSIM does not provide a Costa Rican phone number and does not replace a local SIM when traditional national calls or SMS are essential. It avoids the airport retail and prepaid-line registration process because it is a travel data plan rather than a new local voice line.
Airport SIM vs city store vs Roafly eSIM
A city store is the better physical-SIM environment because employees can explain prepaid packages, register the number and troubleshoot activation. However, it should not automatically be described as cheaper than LIR: no verified airport total is published, so a direct price comparison is not possible.
The trade-off is time. SJO is in Alajuela rather than central San José, and travelers heading directly to another region may not want to divert to an operator shop. LIR arrivals often continue toward beach destinations where store locations and opening hours may be less convenient than in Liberia.
Roafly is generally the practical option for visitors who need data as soon as they land. You can install the eSIM before departure, keep your primary physical SIM in the phone and use the purchased data allowance for hotspot sharing. The supplied Costa Rica network is ICE kölbi. For broader planning, see Best eSIM for Costa Rica and How to Get Internet in Costa Rica.
A local physical SIM remains preferable when you specifically need a +506 number, national calling, conventional SMS or a longer-term prepaid arrangement.
Airport WiFi
SJO WiFi
Juan Santamaría International Airport advertises free wireless internet throughout the airport under the network name “SJO Free WiFi.” One official service page also references access around boarding gate 17, while the airport homepage describes WiFi as available throughout the terminal. No official session duration, speed guarantee or international-number verification requirement is clearly published.
Use the connection to message a driver, download an eSIM, retrieve reservation details or check directions. Do not depend on it for continuous connectivity after leaving the terminal.
LIR WiFi
Guanacaste Airport offers free, unlimited WiFi throughout the terminal. Select the “VINCI Airports Wifi” network and follow the connection steps shown on the login page.
The airport does not state that the connection continues outside the terminal or into ground-transport areas. Complete essential downloads before walking toward your shuttle, bus or rental car.
Best option by arrival situation
Landing at SJO and continuing directly to San José: Use airport WiFi on arrival, then visit an official operator store if you need a Costa Rican number. Choose Roafly when you need navigation or messaging immediately.
Landing at SJO and transferring outside the Central Valley: Set up the Roafly eSIM before flying. Searching for a physical SIM after landing may delay your onward journey.
Landing at LIR during normal retail hours: Check the airport’s Claro outlet, but ask for the complete price and package validity before paying. Keep a digital alternative ready because its hours and stock are not published.
Arriving at LIR late or on a tight transfer: Do not rely on the Claro counter being open. Activate your eSIM before departure or while connected to terminal WiFi.
Staying several weeks or requiring local calls: Use an official kölbi, Claro or Liberty store after arrival. Bring your passport and have staff register and test the line.
Using a dual-SIM phone: Keep your home SIM active for incoming messages where roaming conditions permit and use Roafly for Costa Rican mobile data.
FAQs
Can I buy a SIM card at SJO Airport?
No mobile operator or confirmed SIM-card counter is currently identified in SJO’s official shopping directory. Availability through a general retailer may vary, so a physical airport SIM should not be considered guaranteed.
Is there a SIM-card shop at LIR Airport?
Yes. Guanacaste Airport officially lists Claro among its stores. However, the airport does not publish the shop’s exact location, opening hours, packages or prices.
How much does a Costa Rica airport SIM cost?
Current airport prices are not reliably published for either SJO or LIR. The official kölbi SIM Turista tariff is ₡12,095, approximately US$27, but this is not a verified airport-counter total.
Do I need a passport to buy a Costa Rica SIM?
Plan to present your original passport. Costa Rican prepaid lines must be registered, and the seller needs identifying information to complete that process.
Does a Costa Rican physical SIM include a local number?
A properly activated local prepaid SIM normally provides a Costa Rican number. Confirm the number and included calling balance with the seller before leaving.
Is airport WiFi free?
Yes. Both airports advertise free WiFi. LIR specifically describes its “VINCI Airports Wifi” connection as free and unlimited throughout the terminal.
Can I activate a Roafly eSIM using airport WiFi?
You can download or finish setting up an eSIM while connected to WiFi, but installing it before departure is safer. This avoids depending on an airport login page or troubleshooting after a long flight.
Can I use the Roafly eSIM as a hotspot?
Yes. Hotspot use draws from the same data allowance you purchased; there is no separate hotspot quota.
Should I buy at the airport or in the city?
Choose a city operator store when you need a local number, calls, SMS or in-person registration help. Choose Roafly when immediate data and avoiding airport stock uncertainty matter more.
Final recommendation
For SJO, do not rely on finding a physical SIM in arrivals because the airport’s official directory does not confirm an operator seller. For LIR, the listed Claro store makes an airport purchase possible, but unpublished prices, hours and package details mean it should still be treated as uncertain.
The most predictable setup is to install a Roafly Costa Rica eSIM before departure and use ICE kölbi data from arrival. Travelers who need national calls or a Costa Rican telephone number can use the eSIM initially, then purchase and register a physical prepaid SIM at an official city store.
