A Costa Rica SIM card for tourists can mean either a domestic prepaid line purchased locally or a travel eSIM arranged before departure. The better choice depends mainly on whether you need a Costa Rican telephone number, how long you are staying and whether your phone supports eSIM.
Quick answer: Choose a travel eSIM for a short trip when mobile data, maps and app-based communication are enough. Choose a local prepaid SIM when a Costa Rican number or a domestic long-stay package is important. Before buying either, confirm that the phone is unlocked; for an eSIM, also verify support on the exact regional model.

When a travel eSIM is the practical choice
A travel eSIM avoids searching for a shop after a flight. You can install the profile on reliable Wi-Fi at home, keep the physical SIM in place and use data after landing. This is useful for opening a map, contacting accommodation or checking onward transport immediately.
NoveSIM Costa Rica plans are data-only unless the exact product states otherwise. They do not provide a local number, conventional calls or SMS. WhatsApp, Signal, FaceTime, email and other internet services can use the data connection. Existing app accounts normally keep their registered number; installing a data eSIM does not require changing it.
An eSIM is not automatically the best option for every remote route. It connects through the local partner access available to the selected plan, so it cannot create coverage inside a radio dead zone. Compare the itinerary using the Costa Rica coverage guide, not only the headline package size.
When a local prepaid SIM makes more sense
A domestic SIM is worth considering when a business, landlord or local contact expects a Costa Rican number. It may also suit a longer stay when a renewable domestic bundle is more useful than a fixed travel package, or when the phone has no eSIM capability.
Purchase from an authorised outlet and follow the provider’s current registration rules. Bring the identification requested by the seller. Do not assume that every airport, border point or small town has stock, or that a kiosk will be open when a late flight arrives. If connectivity is needed for the first transfer, arrange a temporary option before relying on a local purchase.
Removing the home SIM can interrupt calls and verification texts. Store it safely and know how the device handles two lines. A phone with one physical slot and eSIM support can often keep both the home number and a travel data line available without swapping tiny cards.
Check the phone before spending money
Both options require an unlocked handset. A carrier lock can prevent a foreign physical SIM and a travel eSIM from registering. Confirm status with the original carrier or in the device settings before departure.
For eSIM, check the exact model number and regional version. An “Add eSIM,” “Add Mobile Plan” or “Download SIM” option is useful evidence, but corporate device policy can still block installation. Do not buy solely because another phone from the same model family supports eSIM.
Coverage matters more than the SIM format
A physical SIM and an eSIM are simply different ways to provision service. Real coverage depends on the network available to the plan, the handset’s bands, terrain, buildings and congestion. San José and established beach towns generally present fewer problems than forest reserves, mountain roads and remote peninsulas.
La Fortuna town may be connected while nearby trails are not. Santa Elena and the Monteverde reserves can behave differently. Tortuguero, Corcovado and remote parts of the Osa Peninsula require offline preparation regardless of how much data the package contains.
How to compare the total cost
Compare more than the advertised price. Include transport to a seller, registration time, validity, full-speed allowance, top-up method and hotspot rules. For a short visit, paying slightly more for data ready on arrival may be rational. For a long stay, the ability to renew a domestic plan can outweigh the initial inconvenience.
Estimate usage before choosing a package. Maps and messages are light; video, cloud backups and tethering are heavy. The Costa Rica data guide helps translate activities into an allowance. Buying extra gigabytes will not improve rural reception.
Safe dual-SIM settings
- Label each line clearly, for example “Home” and “Costa Rica.”
- Select the Costa Rica line for Mobile Data.
- Enable Data Roaming on a travel eSIM when its instructions require it.
- Turn data roaming off on the home SIM.
- Disable automatic mobile-data switching.
- Check which line is selected for calls and messages before using them.
Keeping the home number active does not make roaming free. The original carrier may charge for calls, voicemail and SMS even while the Costa Rica line supplies data. Review those prices separately.
Buying after arrival without losing connectivity
If you plan to buy locally, save the seller location, opening hours, accommodation address and first transfer route offline. Airport Wi-Fi can help, but it is not a substitute for data once the journey continues. Ask staff to confirm an official Wi-Fi network name before joining it.
After a physical SIM is activated, test mobile data, an outgoing call if included and the displayed number before leaving the shop. Keep the receipt and package details. For an eSIM, install on stable Wi-Fi, keep the QR code private and do not delete the profile as an early troubleshooting step.
FAQ
Can tourists buy a prepaid SIM card in Costa Rica?
Yes, subject to the seller’s current availability, identification and registration procedure. Buying from an authorised outlet gives you the clearest activation and support path.
Is an eSIM better than a local SIM in Costa Rica?
An eSIM is usually more convenient for a short data-focused trip. A local SIM can be better for a long stay or when a Costa Rican number is essential. Coverage depends on the plan’s network access, not whether the SIM is digital or physical.
Will a Costa Rica travel eSIM include calls and SMS?
NoveSIM Costa Rica plans are data-only unless the product explicitly says otherwise. Calls and messages through internet apps can use the data connection, but a local telephone number is not included.
Can I keep my home SIM while using a Costa Rica eSIM?
Usually yes on a compatible dual-SIM phone. Select the eSIM for data, disable data switching and check the home carrier’s charges before using calls, voicemail or SMS abroad.
Final Recommendation
For a typical short holiday, a Costa Rica SIM card for tourists does not have to be physical: use a travel eSIM when the phone is compatible and a local number is unnecessary. For a long stay or genuine local-calling requirement, buy a domestic prepaid SIM from an authorised seller.
Choose by itinerary and communication needs, not by SIM format alone. Confirm unlock status, compare the exact plan terms and keep offline maps for the parts of Costa Rica where neither an eSIM nor a physical SIM can overcome missing coverage. If an installed eSIM has a problem, keep the profile and contact support rather than deleting it prematurely; use data.esim only when NoveSIM manual APN entry is required. See the Costa Rica mobile internet guide for the wider comparison.
