You arrive at San José airport, step out for your first coffee, and discover your phone has no signal. With an eSIM Costa Rica, that moment simply doesn't exist: you land with active data and start moving from minute one. In this guide, we tell you how to get reliable internet in the land of pura vida without paying absurd roaming fees from your operator, what coverage to expect between volcanoes and beaches, and how many gigabytes you need depending on your route.
Why you need data in Costa Rica
Costa Rica is a destination best experienced on the move: today a volcano, tomorrow a Pacific beach, and the day after a Caribbean national park. That freedom depends on one very specific thing: having internet in your pocket. Without data, booking a last-minute canopy tour, finding the right turn-off to your lodge, or paying for parking at a park via an app become minor odysseys.
Hotel and cafe Wi-Fi exists, yes, but it is irregular and slow once you leave the major tourist areas. In jungle lodges, you often only get a signal at reception, and it disappears completely as soon as you venture onto the trails. Therefore, relying solely on Wi-Fi ties you to specific locations precisely when the good stuff is elsewhere.
With an eSIM, you have your own connection from the moment you land: Google Maps to drive without getting lost, WhatsApp to coordinate transfers, your bank app to pay, and your camera always ready to upload your photos. It's the difference between adapting your trip to where there's Wi-Fi and designing your trip your way. When the time comes, you can choose your eSIM and land already connected.
Coverage and networks: Kölbi, Claro, and Movistar
The country has three main operators. Kölbi, from the state-owned ICE, has the widest geographical reach, especially in rural, mountainous, and hard-to-reach areas, where it is often the only one with a signal. Claro and Movistar offer very good performance in urban and tourist areas, with solid 4G/LTE speeds in the Central Valley and on the coast.
A good travel eSIM doesn't tie you to a single network: it connects to the strongest available network at each point, so you take advantage of Kölbi's broad coverage inland and Claro or Movistar's speed in the city. This is key in a country where you can go from a well-connected capital to a cloud forest trail in an hour's drive.
| Operator | Strength | Best for |
|---|---|---|
| Kölbi (ICE) | Rural and mountain coverage | Monteverde, Arenal, remote areas |
| Claro | 4G speed in cities | San José, Liberia, Pacific coast |
| Movistar | Balanced coverage/speed | Mixed city-beach routes |
Important point: 4G coverage is very good in 90% of tourist areas, but drops drastically inside national parks and deep jungle, as we will see later.
How many GB to get based on your trip
The amount of data depends on your travel style and how much you use your mobile for maps and video. The good news is that with PuraSim's eSIM Costa Rica, you can start with a basic plan and upgrade without changing anything if you run short. A simple rule: browsing, chat, and email consume little; video streaming and video calls consume the most.
- Short trip (5-7 days): 3-5 GB if you use Wi-Fi at the hotel and rely on data for maps and messaging.
- 2-week trip: 8-10 GB for comfortable use combining Maps, social networks, and uploading photos.
- Nomad or intensive use: 15-20 GB or a large data plan if you make video calls or work from the lodge.
If you're going to travel a lot by car, add a buffer: Google Maps with constant navigation consumes more than people think. To properly size your plan, it will help to read how much data do I need for my trip before deciding. And remember that PuraSim allows for hotspotting, so a single plan can provide internet to your companion's tablet or laptop.
How to activate your eSIM with the QR
Activating an eSIM is one of the easiest things to prepare before a trip, and it takes less than a minute. The key is to get it ready before leaving home, with your usual Wi-Fi, so you arrive in Costa Rica with everything configured and just have to turn it on.
The general process is this:
- Purchase your plan and instantly receive the QR code by email.
- On your phone, go to Settings > Mobile Data > Add eSIM (or Add Data Plan).
- Scan the QR with your camera and follow the steps to install the profile.
- Upon landing, activate the eSIM data and the roaming for THAT profile.
Romi's tip: install the eSIM at home but don't activate data until you arrive. That way you don't use up your plan prematurely and you land instantly connected.
You need an eSIM-compatible mobile phone that is unlocked from its operator. If this is the first time you've heard of this, take a look at what an eSIM is to understand how the technology works. And if you have any questions during installation, PuraSim's 24/7 Spanish-language support will assist you through the process.
Coverage by zone: from San José to Tortuguero
Costa Rica is small but very diverse, and coverage changes depending on the area. Here's a quick guide to the most popular destinations so you know what to expect at each stop on your route.
- San José and Central Valley: excellent 4G coverage. Well-connected city, no problems for anything.
- Tamarindo (Guanacaste): very good signal in the town and beach area; it's a well-covered tourist hub.
- Manuel Antonio: good coverage in Quepos and the town, but drops inside the national park; download the offline map before entering.
- La Fortuna / Arenal: solid signal in the town and most hotels; somewhat weaker near the volcano and on trails.
- Monteverde: acceptable coverage in Santa Elena, but irregular in the cloud forests due to the topography. Kölbi usually holds up better.
- Tortuguero: very remote canal and jungle area; limited and intermittent coverage. Expect to disconnect.
Important note: inside national parks and deep jungle (Corcovado, Tortuguero, Monteverde trails) the signal is scarce or non-existent. Download maps, tours, and reservations offline before venturing in.
The practical conclusion: in towns, cities, and beaches, you'll have plenty of internet; in the wild, be prepared for a disconnection that, to be honest, is also part of the charm of the trip.
Practical tips: colón, nature, and rain
Beyond data, a few practical tips will make your trip easier. First, money: the local currency is the Costa Rican colón (CRC), although the US dollar is accepted in many tourist places. Having internet allows you to check the real exchange rate of the day and avoid accepting abusive rates when paying.
Regarding the climate: Costa Rica has a dry season (December-April) and a rainy or "green" season (May-November). During the rainy season, heavy but brief downpours occur, usually in the afternoon. Having internet helps you check the weather radar and organize excursions in the morning, when it is usually clear.
- Learn "pura vida": it serves to greet, say goodbye, thank, and say that everything is fine. It is the soul of the country.
- Drive with plenty of time: secondary roads and paths to lodges can be dirt and slow. Maps with data is your best ally.
- Respect nature: do not feed wildlife and always stay on marked trails in parks.
- Carry cash in colones for tolls, park parking, and small stands where cards don't work.

Prices: roaming rates vs eSIM
Here's the difference that makes the biggest impact on your wallet. If you activate your Spanish plan in Costa Rica, you enter your operator's international roaming rates, which in Central America can skyrocket to several euros per megabyte or involve expensive daily bonuses with very limited data. One oversight and your travel bill inflates without warning.
An eSIM works the other way around: you pay a fixed and known price before you leave, with no surprises or surcharges. You know exactly how much you're spending and how much data you have. With PuraSim, plans for Costa Rica start from $0.85, a fraction of the cost of any traditional roaming package.
| Option | Approximate cost | Risk of surprises |
|---|---|---|
| Roaming from your operator | Expensive bundles or per-MB rate | High (inflated bills) |
| Local SIM at the airport | Cheap but with queues and paperwork | Medium (time and registration) |
| PuraSim eSIM | From $0.85, fixed price | None |
To understand why traditional billing is so expensive, we recommend reading what roaming is and how to avoid it. And if you want to delve deeper into how plans for traveling through several countries work, our guide to the international eSIM explains it in detail. PuraSim covers 218 destinations, so your next trip will also be sorted.
Frequently Asked Questions
Does the eSIM work as soon as I land in Costa Rica?
