If you're planning a trip to Costa Rica, you've probably already thought about the beaches, volcanoes, and sloths. But there's one significant detail: how to get internet in Costa Rica without getting a shock on your bill or being left incommunicado in the middle of the jungle. In this guide, I compare, transparently, all the ways to connect—from your usual provider's roaming to a local Tico SIM—so you can make an informed decision and always have your mobile at hand from the moment you land.
How connectivity works in Costa Rica
In Costa Rica, mobile telephony operates with three providers and a reality heavily influenced by geography: where people live and work, there is good network coverage, and where wild nature begins, there isn't. How much it costs to connect and what coverage you'll have depends mainly on where you go, not just which option you choose.
The first idea I want you to take away is that "having data" isn't enough here: you need to plan your connection before leaving home. The country has a very decent 4G network in the Central Valley (San José, Alajuela, Heredia) and in major coastal tourist areas, and by mid-2025, 5G will be available in some cities. But national parks, the Osa Peninsula, or the deep Caribbean are a different story: there, the signal drops significantly with any company.
That's why it's important to separate two distinct decisions. One is how you connect (roaming, Wi-Fi, Tico SIM, or eSIM), which affects price and convenience. The other is where you will be each day, which determines whether you'll have a signal or not. With that mental map in mind, the rest of the guide will make much more sense, and you'll avoid the two typical surprises: the inflated bill and the "I can't get any signal here" moment.
The four options to connect
To get internet in Costa Rica, you have four options: roaming with your Spanish provider, Wi-Fi in hotels and lodges, a local Tico SIM purchased with your passport, and an eSIM that you activate before you travel. eSIM is usually the most practical and cheapest; the local SIM is the most economical for long stays.
Each has its moment, which is why I've presented them as four very different paths instead of just selling you one. Before delving into the details of each, here's a quick overview so you can see at a glance where each option fits based on your type of trip, budget, and how much hassle you want to deal with.
| Option | Estimated cost | Convenience | Ideal for |
|---|---|---|---|
| Spanish roaming | High (packages or per MB) | Zero hassle | Very short trips |
| Hotel/lodge Wi-Fi | Free | Only at accommodation | Occasional queries |
| Local Tico SIM | Low (from ~ $2-5 for SIM) | Requires passport and store visit | Long stays |
| Travel eSIM | Medium-low | Activates automatically | Most travelers |
None is "the best" in abstract: it depends on how many days you stay, whether you travel alone or with family, and how much coverage you need outside tourist routes. In the following sections, I break down all four with real prices and their fine print.
Roaming with your Spanish provider
Here's the first important warning: Costa Rica is not part of the European Union, so the "roam like home" rate you use in France or Italy does not apply. The moment your mobile connects to a Tico network, you'll be charged international roaming rates, which for many Spanish providers are counted in individual megabytes at prices that range, depending on the company, from several euros per MB to daily packages that can devour your budget in two days.
Roaming has one major advantage: you don't do anything. You arrive, turn on your phone, and it works. But that convenience comes at a cost, and often the surprise bill upon return is what drives people to seek alternatives. Before relying on it, call your provider and ask for the exact price outside the EU.
If you're still considering roaming, carefully check the temporary travel bundles sold by some providers for "zone 2" or "rest of the world," because they can sometimes be worthwhile for two- or three-day trips. To understand how all this is calculated, I recommend my guide on how much international roaming costs, and if you want a direct comparison, I have an eSIM vs. roaming comparison with concrete numbers.
Hotel and lodge Wi-Fi
Free Wi-Fi is your ally for anything non-urgent. Almost all hotels in the Central Valley and large beach areas (Tamarindo, Manuel Antonio, Jacó) offer decent Wi-Fi in common areas, and many restaurants and cafes in San José do too. For uploading photos, making video calls at night, or planning the next day, using the lobby Wi-Fi at nine in the evening is more than enough and costs you nothing.
The problem arises when you leave the hotel. Wi-Fi doesn't follow you on the road, on the trail, or when you need Waze to find a hidden park entrance. And in jungle eco-lodges, where you'd most want to show off your photos, the connection is usually slow, shared among twenty guests, and sometimes limited to reception for a few hours a day.
Another downside is security: on open networks, it's advisable not to enter bank details without a VPN. My advice is to treat Wi-Fi as a complement, never as your sole network. If you want to see why portable Wi-Fi doesn't entirely solve the problem, check out my comparison of eSIM versus pocket Wi-Fi, where I explain the hassle of batteries and deposits.
Local Tico SIM: Kölbi, Claro, and Liberty
A local SIM is the cheapest option if you're staying many days or consuming a lot of data. The three operators are Kölbi (from the state-owned ICE, by far the best rural and park coverage, nearly 95% of the country), Claro, and Liberty (formerly Movistar), the latter two offering very good speeds in the city and 5G deployment. Kölbi even has tourist packages with several GB of data, extra gigabytes for apps like WhatsApp, and some call minutes.
The downside is the hassle. By law, buying a prepaid SIM in Costa Rica requires registering it with your passport, so you'll have to queue with your passport in hand at an official store or at the vending machines at San José airport (there's one in the arrivals terminal). The SIM costs around $2-5, and top-ups start at about $5, but you'll have to manage with the operator's app in Tico Spanish and with the registration process.
If you're traveling for a month, living very locally, or need a Tico number for administrative purposes, it's worth it. For a two-week tourist route, many travelers prefer to avoid the hassle. I compare it in detail in my article on eSIM versus local SIM so you can see when each one pays off.
The eSIM, my recommended option
For the vast majority of trips to Costa Rica, my recommendation is a data eSIM. It's a digital SIM that you buy online, receive by email, and install by scanning a QR code: you can activate it from your couch at home days before you fly and arrive at San José airport already connected, without having to search for stores or deal with passport formalities. If you've never used one, my guide on what an eSIM is explains it step-by-step.
The advantages are clear. You keep your Spanish number active in the physical slot of your phone (to receive bank SMS or calls), while data runs through the eSIM. There's no plastic to lose, no deposit, and if you choose wisely, you'll connect to the network with the best coverage in the area. The only requirement is that your phone is compatible, which is true for almost all models from recent years.
The honest downside: for very long stays and huge consumption, a rechargeable local SIM might be slightly cheaper per GB. But when you factor in convenience, the absence of paperwork, and not depending on a store, the eSIM wins for the average traveler. You can find all the fine print in my eSIM guide for Costa Rica.
Actual coverage: city yes, parks no
This is the section that most people skip and then regret, so I'm writing it in mental capital letters. In San José, the Central Valley, touristy Guanacaste, and the most visited beaches, coverage is good, and you'll have more than enough. The problem arises as soon as you venture into real nature: no matter how much you want to, there are places where going deep into the jungle without coverage is simply normal, and no operator or eSIM can fix that.
Inside Corcovado, in the Tortuguero canals, or at the tip of the Osa Peninsula, you won't have a signal with any company. Download maps and inform your family before entering.
As a quick reference, this table summarizes what to expect in the most popular natural destinations. Kölbi maintains coverage best in rural areas, but even it can't perform miracles in the most isolated corners.
| Area | Mobile coverage | What to expect |
|---|---|---|
| San José and Central Valley | Very good (4G/5G) | Smooth connection at all times |
| Tourist beaches (Guanacaste, Manuel Antonio) | Good | Some areas with irregular signal |
| Monteverde (town) | Acceptable | Good in town, weak in lodges |
| Corcovado / Osa | Scarce or none | Prepare to be disconnected |
| Tortuguero | Practically none | Only accessible by boat or small plane |
Moral of the story: where there's a network, you'll connect; where there isn't, no magic is possible. Plan your park days assuming you'll be without a signal.
How much data you really need
The million-dollar question. The good news is that calculating gigabytes wisely is easier than it seems if you separate by usage type. As a general rule, an average traveler uses about 1 GB per day: light use (maps, messaging, some web browsing) is around 0.4 GB, while intensive use with social media, video, and photo uploads can go up to 2.5 GB daily or more.
For a typical two-week trip, this translates to a range of between 10 and 30 GB. If you rely heavily on hotel Wi-Fi at night, you'll stay on the lower end; if you do live streams and video calls every day, aim for the higher end or a generous data plan. Here's a table to make it clear.
| Profile | Daily consumption | 10-14 days |
|---|---|---|
| Light (maps and chat) | ~0.4 GB | 5-8 GB |
| Medium (social media and browsing) | ~1 GB | 10-15 GB |
| Intensive (video and live streams) | ~2.5 GB | 25-35 GB |
My trick: since you'll be without data in the parks anyway, don't inflate your calculation thinking you'll consume data every day. And if in doubt, opt for a plan with some margin or a top-up option; running out of data on the second-to-last day is a typical avoidable hassle.
How to choose and activate your connection
Choosing well involves cross-referencing three pieces of information: travel days, estimated gigabytes, and the coverage you need outside the city. If your route involves a lot of nature, prioritize an option supported by the network with the best rural reach. If you're moving between San José and well-known beaches, almost any option will work, and convenience will be more important. The key is to get everything ready before taking off and not improvise at the airport.
With an eSIM, the process is quick. These are the steps I follow:
- Check if your phone is eSIM compatible (phone settings or manufacturer's website).
- Buy the plan with the GBs and days that suit you, a few days before flying.
- Install the profile by scanning the QR code you receive by email, using Wi-Fi at home.
- Set the eSIM for "data" and your Spanish SIM for calls and SMS.
- Upon landing, activate the eSIM's data roaming, and you're good to go.
A practical note: install the profile at home, but don't activate it until you arrive, to avoid using up plan days prematurely. And keep a screenshot of the QR handy just in case. With that, you'll leave Juan Santamaría Airport with Google Maps working and without having wasted a single minute looking for where to buy a signal.
Tips to avoid losing signal
Even with the best connection, you're bound to experience periods without coverage in Costa Rica, and that's where a couple of habits make all the difference. The most important: download offline maps from Google Maps or Maps.me for all the areas on your route before leaving the hotel. Having downloaded maps offline will save you from getting lost on unnamed dirt roads, of which there are plenty.
Other habits that have helped me out of more than one tight spot:
- Inform your family which days you'll be unreachable (parks, boat trips).
- Download tickets, reservations, and boarding passes to your phone in case there's no network upon arrival.
- Save music playlists or podcasts offline for long road trips.
- Carry a power bank: searching for a signal in fringe areas significantly increases phone battery consumption.
A surprising fact: more and more eco-lodges are installing Starlink, so you might have satellite Wi-Fi in the middle of the jungle where no mobile data signal reaches. Don't count on it, but it's a pleasant bonus. By combining eSIM for daily use, Wi-Fi for heavy tasks, and these little tricks for gaps, your trip will be covered from start to finish without any scares.
Frequently Asked Questions
Does my Spanish provider's roaming work in Costa Rica?
Yes, but at international roaming prices, not European rates. Costa Rica is not in the EU, so "roam like home" does not apply. Check the exact cost per MB or the travel bundle before you leave, as it tends to be expensive.
Do I need my passport to get a connection?
Only if you buy a local Tico SIM: the law requires you to register it with your passport at an official store or airport machine. With a travel eSIM or roaming, no in-person process or document is needed.
Will I have coverage in national parks?
Generally, little to none. Corcovado, Tortuguero, and the Osa Peninsula are practically without signal with any operator. Monteverde town has acceptable coverage, but jungle lodges are weak. Download offline maps and assume you'll be disconnected for much of those days.
How many gigabytes should I contract for two weeks?
For average use, between 10 and 15 GB is usually sufficient; if you take many photos, videos, or do live streams, aim for 20-35 GB. Remember that you won't consume data in the parks, so don't inflate your calculation thinking you'll spend data every day.
Which Tico operator has the best coverage?
Kölbi, from the state-owned ICE, has the broadest reach in rural areas and parks, covering nearly 95% of the country. Claro and Liberty offer very good speeds in cities, with 5G rolling out from 2025, but lose strength in deep rural areas.
Can I still use WhatsApp with my usual number?
Yes. With a data eSIM, you keep your Spanish number active in the physical SIM for SMS and calls, and WhatsApp continues to work with that number using the eSIM's data. You won't lose your account or chats at any time.
Is hotel Wi-Fi sufficient?
For evening and non-urgent tasks (uploading photos, video calls, planning), yes. But it doesn't follow you on the road or trails, and in jungle lodges, it tends to be slow and shared. Treat it as a supplement, not your sole network.
When is a local SIM better than an eSIM?
A local SIM is better for long stays (a month or more) or if you consume a lot of data, because the price per GB might be lower. For trips of one or two weeks, the eSIM wins for convenience: no queues, no passport, and active before you fly.
Conclusion
To summarize the map: roaming is convenient but expensive, Wi-Fi is free but limited to the hotel, a local SIM is cost-effective if you stay a long time but requires a passport and paperwork, and an eSIM is the sweet spot for most travelers. And above all, the Costa Rican lesson: in the city and at the beach you'll have plenty of coverage, in the parks assume you'll be without signal and download your maps. With that, your "pura vida" won't be interrupted by a single data outage.
If you want to forget about it and arrive connected from the first minute, check out the PuraSIM eSIM for Costa Rica: buy it, install it at home, and land in San José with Google Maps working. Have a good trip and see you among the volcanoes.
