eSIM Costa Rica: Mobile Data Without a Card to Pick Up
An eSIM Costa Rica plan from Anosim gives your phone mobile data on a local network, with nothing to fetch at the airport and no contract to sign. You add the eSIM at home, switch it on in Costa Rica and leave your regular SIM card where it is. Read on for the towns with named coverage, a phone checklist, the steps on arrival and a way to handle SMS codes for bookings. More destinations are waiting on the eSIM overview.
A Costa Rica eSIM card that is not a card
Many people search for a Costa Rica eSIM card, but there is no plastic involved. An eSIM is a chip built into your phone, and the plan arrives as a digital profile that you load with a QR code. Nothing gets posted to you, and nothing needs to be swapped in the SIM tray.
The Costa Rica eSIM from Anosim is a pure data plan. Maps, messengers, translation apps and WhatsApp calls run over it, while it has no phone number of its own and no voice minutes.
Eight towns with named coverage
Coverage is named for these places and for other cities:
- Central Valley: San José, Alajuela, Heredia and Cartago
- Guanacaste in the northwest: Liberia
- Pacific coast: Puntarenas
- Caribbean coast: Puerto Limón
- The south: Buenos Aires, a Costa Rican town that shares its name with the Argentine capital
Rainforest lodges, volcano trails and remote beaches are not on this list. Plan for patchy or no signal there, and save offline maps and booking confirmations before you leave a town. Depending on the network operator and the location, the eSIM uses 3G, 4G/LTE or 5G, and the operator may slow speeds under its fair-use rule.
Phone checklist before you pack
Five minutes with your phone now saves an hour of trouble later:
eSIM support
Open the mobile or SIM section of your settings. If there is an option to add an eSIM, the phone can take one.
No carrier lock
A phone tied to one carrier with a SIM lock will refuse the profile. Ask your carrier to unlock it before the trip. Note that certain iPhone versions from mainland China, Hong Kong and Macau were built without eSIM.
Wi-Fi at hand
The QR code can only be scanned while the phone is online, so install it at home or wherever you have reliable Wi-Fi.
Keep the profile
After installation, leave the eSIM profile on the phone. The QR code is single-use; deleting the profile or scanning the code again will not give you a second installation, so talk to support instead.
Ordering and installing at home
Open the eSIM page, search for Costa Rica and pick a data plan. Log in and pay from your Anosim balance, which you can fill with cryptocurrency or a bank transfer. Nobody asks you for a passport or ID. You end up with a prepaid eSIM for Costa Rica: no contract, no monthly charge.
The QR code shows up straight after payment, and the plan is stored under My eSIM Plans in your account. Scan it, then switch the new line off until you arrive. You have 180 days from the purchase to make the first connection, and the plan's validity only begins with that connection in Costa Rica.
Landing at the airport near San José or in Liberia
Most international flights arrive at the airport near San José or in Liberia. Once you are through to the arrivals area, turn the eSIM on, choose it as the line for mobile data and enable data roaming for it. Expect a local network within one or two minutes.
Nothing yet? A reboot, a quick round of airplane mode and automatic network selection usually solve it. Our support is reachable at any hour through Telegram, the website chat and email.
Group tours, shared rides and hotspot
On a guided tour or a shared shuttle, it is tempting to give the whole group your connection. Whether the Costa Rica plan allows hotspot depends on the network operator, so it is safer if every traveller with an eSIM phone has their own plan.
Whichever offer you consider the best eSIM for Costa Rica, two things stay the same with Anosim: your regular SIM remains in the phone, so your usual number is still reachable on WhatsApp, and Costa Rica sits outside the EU roaming rules, so a data plan of your own makes sense if you travel from Europe.
Booking codes by SMS: add a number
Tour operators, rental cars and payment apps sometimes confirm a booking or login with an SMS code. The eSIM cannot receive it because it has no number. An Anosim number fills that gap:
- Activation is enough for a one-off confirmation.
- Rent Service keeps a number tied to a single service for repeat checks.
- Rent Number gives you a complete number for all services while you rent it.
If a number is virtual, it is labelled as such in the provider selection.
Frequently asked questions
Does the eSIM work in Liberia and Puntarenas?
Yes, both are on the coverage list, together with San José, Alajuela, Heredia, Cartago, Puerto Limón, Buenos Aires and other cities.
Is a physical card involved at all?
No. The eSIM is a digital profile that you install by scanning a QR code. There is nothing to collect or insert.
Is the Buenos Aires in the coverage list the one in Argentina?
No. It is a town in southern Costa Rica with the same name.
When should I add the eSIM to my phone?
Ideally a few days before you fly, while you are on your home Wi-Fi. Leave it off for the flight and turn it on once you are in Costa Rica.
Will my Costa Rica plan start when I buy it?
No. It starts with the first connection to a supported network in Costa Rica. That first connection has to happen within 180 days of the purchase.
Can I run a laptop on the eSIM data?
Only if hotspot is possible, and that depends on the network operator in Costa Rica.
Can a tour operator text me on the eSIM?
It cannot, because there is no number on the eSIM. Texts still reach your regular SIM, and for verification codes you can use an Anosim number.
