Top eSIM Providers for Costa Rica

Several reputable providers offer coverage in Costa Rica. They all use local networks like Kölbi, ICE, and Movistar, which cover the country well, including remote areas. Here are the top choices:

• Airalo – Popular for regional plans. Offers Costa Rica-specific packages like 1GB for 7 days or 5GB for 30 days.
• Airalo – Wait, avoid repetition. Let's correct.

Let me write a proper list:

• Airalo – Offers flexible Costa Rica data packs. Sizes range from 1GB to 10GB, valid 7 to 30 days. Prices are competitive.
• Holafly – Famous for unlimited data plans. Their Costa Rica plan gives you unlimited data with fair usage policy.
• eSIM Flux – Our own recommended plans for Costa Rica, with transparent pricing and 24/7 support. Check out our Costa Rica eSIM plans.

Each provider uses the same networks, so coverage is similar. The difference lies in data limits, price, and customer service. Always check plan details for fair usage policies, especially on “unlimited” plans.

Costa Rica's Mobile Networks and Coverage

Costa Rica has three main carriers: Kölbi (state-run), Movistar, and Liberty (formerly Claro). All provide LTE and 5G in urban areas. In remote rainforests or mountain regions, 4G LTE is common, but you may drop to 3G in very isolated spots. Your eSIM automatically connects to the best available network. For specifics, read our Costa Rica travel guide.

How to Set Up an eSIM for Costa Rica

Setting up an eSIM is straightforward. Follow these steps:

1. Check compatibility – Make sure your phone is unlocked and eSIM-compatible. Recent models from Apple, Samsung, Google, and others work. See our device compatibility list.
2. Purchase a plan – Choose from a provider, like our data plans that include Costa Rica.
3. Receive your QR code – You'll get a QR code via email after purchase.
4. Scan and install – Go to Settings > Cellular > Add Cellular Plan on iPhone, or Settings > Connections > SIM manager on Android. Scan the QR code and follow the prompts.
5. Activate on arrival – Your eSIM activates either immediately or when you land, depending on the plan. Ensure your data roaming is on for that eSIM.

If you have trouble, most providers offer setup guides. In true emergencies, you can find local SIM at Juan Santamaría International Airport (SJO).

Activation and APN Settings

Usually, an eSIM works automatically. However, some devices or providers require manual APN settings. For example, if you use an eSIM from eSIM Flux, you may need to set the APN to “esimflux”. Here’s how:

1. Go to Settings > Cellular > Cellular Data Network.
2. Enter the APN provided by your carrier (e.g., “esimflux” or “airalo”).
3. Save and restart your phone if prompted.

If you encounter issues like no internet or slow speed, check that your cellular data is turned on for the eSIM line, not your home line. For detailed steps, check our installation guide.

Data Usage Tips for Costa Rica

To make your data last, keep these tips in mind:

• Download offline maps before your trip – Google Maps allows offline downloads.
• Connect to Wi-Fi at hotels, restaurants, and cafes when possible.
• Monitor background app refresh – disable for non-essential apps.
• Use data-saving mode on apps like WhatsApp and Facebook.
• Stream videos only on Wi-Fi; video streaming eats data quickly.

Cost Comparison: What to Expect

eSIM plans for Costa Rica typically range from $4 for 1GB (7 days) to $30 for 10GB (30 days). Unlimited plans go for $20–$50, often with throttling after 1GB per day. Local SIM cards can be cheaper per GB, but you have to find a store and may need a passport for registration. International roaming charges from your home carrier are usually the most expensive, often $2–$5 per MB or $10+/day roaming packages. For a 7-day trip, an eSIM might cost you $10–$20, versus $70+ with roaming.

Importance of eSIM for Travel in Costa Rica

Frequently Asked Questions (FAQ)

Is eSIM coverage good in Costa Rica?

Yes, eSIM coverage is excellent in urban and tourist areas. Providers use local networks like Kölbi, which cover most of the country, including popular destinations like San José, Guanacaste, and Arenal. In remote rural areas, you might get slower speeds, but you'll still have signal in most places.

Can I use an eSIM with my current phone?

Most modern smartphones (iPhone XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer) support eSIM. However, your phone must be factory-unlocked or unlocked by your carrier. Check the device Compatibility before purchasing.

Do I need to buy an eSIM before I travel?

Yes, it's best to purchase and install before you leave. You'll have the QR code ready, and it often activates immediately after you land, so you don't need to look for Wi-Fi.

Can I keep my WhatsApp number with an eSIM?

Absolutely. Your eSIM only affects your data. You can keep your home SIM for calls and texts, or use Wi-Fi calling. WhatsApp uses data, so as long as you have an internet connection, you can use WhatsApp with your regular number.

What happens if I run out of data?

You can usually purchase a top-up data pack from your eSIM provider's website or app, even if you're abroad. Alternatively, you can buy a local SIM at a store, though it's less convenient.

Will I be charged for incoming calls while using an eSIM?

No, because you are not using your home carrier's network for cellular calls. However, if you use your home SIM for calls, your regular roaming charges may apply. It’s best to use data-only eSIM and make calls over WhatsApp or FaceTime.
