The local chip route, priced honestly
Costa Rica SIM cards
A prepaid Costa Rican SIM is cheap, gets you a +506 number, and reaches places no travel eSIM can. It also costs you a shop visit and your passport. Here is the whole trade.
Three operators, and only one of them is a real decision Kölbi, Claro, Liberty
| Operator | Owned by | Strength | Buy it if |
|---|---|---|---|
| Kölbi | ICE, the state utility | Widest coverage in the country, Opensignal's Coverage Experience leader for Costa Rica in April 2026 | You are going rural. This is the only reason to buy a physical SIM at all. |
| Claro | América Móvil | Fastest average 4G in SUTEL's 2025 road tests, 5G in larger towns | You want speed in the Central Valley. But your travel eSIM already reaches Claro. |
| Liberty | Liberty Latin America, formerly Movistar | Strong in San José, the Central Valley and the Guanacaste resorts | Rarely worth a shop visit. Your travel eSIM probably defaults to this network anyway. |
That table contains the entire argument. Every travel eSIM sold for Costa Rica already runs on Claro and Liberty, so buying a physical Claro or Liberty SIM gets you the same towers with more paperwork. Kölbi is the only local SIM that buys you something an eSIM cannot. If you are going to make the shop trip, make it a Kölbi trip. The Kölbi page has the detail.
You cannot buy a SIM card at the airport any more SJO and LIR in 2026
This is the single most out-of-date piece of Costa Rica travel advice still circulating, and it matters because arrival is exactly when you need data: to call a ride, to find the rental desk, to message the hotel that your flight was late.
The two workable answers. Either install a travel eSIM at home so you land connected and buy a local chip later at leisure, or accept being offline for the first hour and drive to a shop. For an SJO arrival that means City Mall in Alajuela, five minutes away, with all three operators inside. For LIR it means downtown Liberia, ten to fifteen minutes out.
Where to buy a Costa Rica SIM card ranked by likelihood of success
Bring your passport. Prepaid (prepago) needs nothing else. Postpaid (postpago) requires a cédula or DIMEX residency card and is closed to visitors.
| Where you are going | Network to prefer | What to expect |
|---|---|---|
| Best options near the airports | ||
| City Mall, Alajuela | 5 min from SJO | Kölbi, Claro and Liberty storefronts under one roof, staff who will set the phone up and test it. The most reliable stop in the country for an arriving traveler. |
| Downtown Liberia | 10–15 min from LIR | All three operators have shops in the town centre. Worth the detour before heading to the Guanacaste beaches or south to Nicoya. |
| Around the country | ||
| ICE offices | most larger towns | ICE is the state utility and Kölbi is its mobile arm. White, blue and yellow buildings. Locals also pay electricity bills here, so expect a queue. |
| Kölbi storefronts | La Fortuna, Huacas, Limón and others | La Fortuna is downtown across from the Cruz Roja; Huacas sits on the road to Tamarindo and Flamingo; Limón is across from the post office. Most other storefronts are in the Central Valley. |
| Claro and Liberty retail stores | widespread | More numerous than Kölbi shops and present in most tourist towns. Useful, but remember you are buying networks your eSIM already has. |
| Only if you speak Spanish | ||
| Supermarkets (Más x Menos and similar) | chip only, at the till | They sell the chip and will not help you activate it. Instructions in Spanish. Fine for a second SIM, painful as your first. |

What a Costa Rica prepaid SIM actually costs in colones, then dollars
| Item | Colones | ≈ USD | Notes |
|---|---|---|---|
| Prepaid chip | ₡500–1,000 | $1–2 | Includes a +506 number |
| Kölbi tourist bundle | ₡12,095 | $24 | 5GB data, 5GB for WhatsApp, Instagram, Facebook and Waze, 100 national minutes, tax included |
| Light top-up | ₡5,000 | $10 | Goes a long way on maps and messaging |
| Heavier top-up | ₡10,000 | $20 | Comfortable for a couple of weeks of ordinary use |
Colón prices from published operator tariffs; dollar figures converted at the September 2026 rate and rounded. Exchange rates move, colón prices move less.
Call it $25 to $26 for a Kölbi line with a real tourist bundle on it. That undercuts Airalo's 10GB at $34.00 and lands close to Yesim's $24.35. On pure price the local chip is competitive. What it costs you is time, a passport, and being offline until you find a shop.
Topping up afterwards is easy in a way that surprises people: most supermarkets and mini-supers can add balance at the register. Ask for Kölbi, Claro or Liberty by name. Kölbi users check their balance by dialling *888*1*1#.
Local SIM card or travel eSIM? the trade in one table
| Local prepaid SIM | Travel eSIM | |
|---|---|---|
| Cost for ~10GB | ≈$25 with the Kölbi bundle | $24.35–$36.99 |
| Networks available | All three, including Kölbi | Claro and Liberty only |
| Connected on landing | no, shop visit first | yes, installed at home |
| Costa Rican number | yes, +506 | only Airalo's Hot Telecom+ packages |
| Keeps your home number active | only on a dual-SIM phone | yes, always |
| Paperwork | passport at the counter | none |
| Works on a locked phone | no (unless dual-SIM second slot) | no |
| Refunds if it fails | argue in Spanish at the shop | support ticket, documented |
The honest summary: for most travelers the eSIM wins on convenience and ties on price, and the local SIM wins the one row that decides rural trips. Which is why our recommendation for self-drivers going south is both, for about $58 total.
If you are not going deep rural, the shop visit buys you nothing your eSIM does not already have. Airalo names its networks at $34.00 for 10GB; Yesim is $24.35 with a Trustpilot caveat we spell out.
See Airalo plans See Yesim plans Or read the Kölbi caseSetting up a Costa Rican SIM card what happens at the counter
- Hand over your passport and ask for prepago. Say the operator by name. At an ICE office, Kölbi is the only option and that is fine.
- The staff install and test it. They will put the chip in, register the line and confirm data works before you leave. Do not walk out until you have loaded a web page.
- Save the number they give you. It is your +506 line, and Costa Rican businesses will use it on WhatsApp rather than calling.
- Top up at any supermarket. Ask for the operator by name at the register. Kölbi balance check: *888*1*1#. Running it alongside an eSIM is covered here.
Costa Rica SIM card questions answered straight
Can I buy a SIM card at San José airport?
Not reliably. The Kölbi desks at SJO and LIR closed. A Claro counter in SJO baggage claim opens irregularly. The nearest dependable option for an SJO arrival is City Mall in Alajuela, about five minutes away, where all three operators have shops.
How much is a prepaid SIM card in Costa Rica?
The chip itself is ₡500 to ₡1,000, about $1 to $2. What you actually pay for is the bundle on top: Kölbi's tourist package with 5GB of data, 5GB more for WhatsApp, Instagram, Facebook and Waze, and 100 national minutes costs ₡12,095 including tax, roughly $24.
Which SIM card is best for tourists in Costa Rica?
Kölbi, and only Kölbi, because it is the one network no travel eSIM can reach. Buying a physical Claro or Liberty SIM gets you the same towers your eSIM already uses, with a shop visit attached. If you are not going rural, skip the SIM entirely and use an eSIM.
Do I need my passport to buy a SIM in Costa Rica?
Yes for prepaid, and that is all you need. Postpaid contracts require a cédula or DIMEX residency card, so they are not available to visitors.
Will a Costa Rican SIM work in my phone?
Only if the phone is unlocked, or if you are putting it in the second slot of a dual-SIM phone, which is unlocked by default. A carrier-locked single-SIM phone will reject the chip. Check with your carrier before you fly, because this is the most common failure people hit.
Can I use a Costa Rican SIM in Panama or Nicaragua?
Not on a domestic prepaid plan. It stops at the border. For a two-country trip, either buy a local plan in each country or use a Latin America regional eSIM. We compare the two approaches here.
Land connected, buy the chip later
The airport desks are gone, so the first hour is the problem a travel eSIM solves. Install one at home, then decide about a Kölbi chip once you know your route needs it.
