« Back to the Guide to Tamarindo
When we first landed in Tamarindo in December 2011, the internet was the thing that stressed me out the most. I work 100 percent online, and that first month there were days I could barely send an email. Fast forward to today and the story is completely different. Our internet in Tamarindo got faster than our internet in Colorado years ago, and a month of local phone data costs about as much as a cheap lunch.
This page covers what actually works in 2026, from phones and eSIMs to home internet and getting real work done from a beach town. (Plus why you’ll be using WhatsApp for pretty much everything.)
The Short Version
- Cell coverage in and around Tamarindo is good, and all three Costa Rican carriers work in town.
- A local prepaid SIM or a travel eSIM is usually the cheapest way to get data. A kölbi 30-day package with 10 GB was ₡5,000 (about $11) in October 2026.
- Bring your passport if you’re buying a physical SIM. Prepaid lines have to be registered.
- Your US plan may work too, but check how much high-speed data it really includes abroad.
- Home fiber is available in town now, and it’s plenty for video calls. Hotels and hostels get slower when they’re full.
- WhatsApp is how everyone communicates here, businesses included. Install it before you come.
- The big holiday weeks (Christmas to New Year, and Semana Santa) still strain the town. If you work online, plan around them.
Cell Phones in Tamarindo
Tamarindo and the towns around it have good cell coverage. Costa Rica has three mobile carriers:
- kölbi, the brand of ICE, the state-owned telecom. Travel guides consistently rate it as having the widest coverage in the country.
- Claro, owned by Mexico’s América Móvil.
- Liberty, which used to be Movistar. You’ll still see the old name on some signs and older guides.
Any of the three works fine in town. If you’re planning road trips into the mountains or the national parks, kölbi is the one most people recommend.
Your Options for Data
| Option | What it is | Where to get it | Good to know |
|---|---|---|---|
| kölbi prepaid SIM | A local number with data, minutes and texts | The kölbi branch in Plaza Huacas (in nearby Huacas) or any kölbi agency | Full packages in October 2026: 7 days, 4 GB: ₡2,000 (about $4) 15 days, 6 GB: ₡3,000 (about $7) 30 days, 10 GB: ₡5,000 (about $11) They renew automatically unless you turn that off. |
| Claro prepaid SIM | A local number with data | The Claro store at Liberia airport (LIR), or the Claro store in Santa Cruz | Ask for the total price and how long the package lasts before you pay. |
| Liberty prepaid SIM | A local number with data | Liberty stores and agencies | Google Maps shows the Liberty store in Tamarindo as permanently closed (October 2026), so don’t count on buying one in town. |
| Travel eSIM | Data you buy online and install before you fly | An eSIM app or website, such as Airalo or Holafly | Your phone has to be unlocked and eSIM capable. Many are data only, so check whether you get a local number. |
| Your US plan | Roaming on your regular number | Your carrier’s app | Easiest, but the fast data allowance can be small. See below. |
Prices are from kölbi’s October 2026 prepaid lineup as reported by Delfino, converted at ₡453 to the dollar (the rate on our cost of living page). Once you have a kölbi line, you can buy packages in the mi kölbi app or by dialing *888#.
Using Your US Plan
Back in 2019 we raved about T-Mobile’s free data roaming here, and we used it a lot. It’s not that simple anymore. T-Mobile’s higher plans now include a set amount of high-speed data abroad (5 GB on Experience More, 15 GB on Experience Beyond, according to T-Mobile), then slow you to 256 kbps, which is fine for WhatsApp messages and painful for anything else. Its Essentials plan doesn’t include that high-speed allowance at all. AT&T and Verizon sell international day passes and plans for an extra fee.
Plans change constantly, so open your carrier’s app before you fly and look up Costa Rica specifically. If you’ll be here more than a week or two, a local SIM or eSIM usually wins.
WhatsApp Is How Tamarindo Communicates
If you only do one thing before your trip, install WhatsApp. A 2024 University of Costa Rica study found that 98 percent of Costa Ricans with a cell phone use it (CRHoy). Here, it’s not just for friends. Businesses run on it too:
- Delivery runs on it. BM Express, the delivery service we use, takes orders on WhatsApp and picks up from virtually any restaurant in town.
- Clinics list WhatsApp numbers. Hospital Metropolitano in Huacas has one on our health and wellness page.
- Even kölbi, the phone company, answers questions on WhatsApp.
WhatsApp calls (or FaceTime) also save you from paying for international calls on a regular phone line. It works on wifi, so even if you skip a local SIM, you can stay in touch from your hotel or a restaurant.
Home Internet and Wifi in Tamarindo
Almost every place you can stay in Tamarindo has wifi. A few things we’ve learned about it over the years:
- Most connections are shared, so the more people on it, the slower it gets.
- Hotels and hostels can crawl at busy times, like at night when everyone is streaming. For email and social media they’re usually fine.
- Vacation rental homes tend to have faster, less crowded connections. If speed matters to you, book a house instead of a hotel.
- Many restaurants have wifi and are happy to give you the password. We’ve worked from plenty of them over the years while we ate, usually when the internet at the house fizzled.
What’s Available Now
| Option | What to expect | Good to know |
|---|---|---|
| Home fiber | Numbeo’s Tamarindo average for a 60 Mbps or faster plan was $59 a month in October 2026. Build Tropical puts fiber at $50 to $80 a month where it’s available. | kölbi sells home fiber, and Liberty and Telecable both run fiber networks in Costa Rica. Which company reaches your street depends on the address, so ask the landlord or your neighbors. |
| Our house, Casa Colorado | Fiber at 350+ Mbps down and 100+ Mbps up, with several networks across the main house and casita | That’s the speed listed on the Casa Colorado site. Video calls and streaming work fine. |
| Starlink | Satellite internet, for places where fiber doesn’t reach | Starlink takes residential orders in Costa Rica. Costa Rica’s telecom regulator counted 26,928 active satellite internet subscriptions in June 2025 (DPL News). In town you probably won’t need it. Check current pricing on starlink.com. |
| Phone hotspot | Your cell data, shared to your laptop | A good backup when the wifi drops. A 10 GB kölbi package won’t last long on video calls, though. |
Our own experience tells the story. In 2011 the internet at our hotel was so unreliable that I’d walk up to the Spanish school to work. By 2021, our internet in Tamarindo was twice as fast as our internet in Colorado. Ten years made a big difference.
Working Remotely From Tamarindo
I’ve been working online from here since 2011. Erin films many of her free Five Parks Yoga classes by the pool at Casa Colorado, our family’s house in Tamarindo, and these days we also work from an RV on the road (that’s what our Five Parks Life channel is about). So we’ve had plenty of practice. What we’d tell anyone planning to work from here:
- Ask for a speed test before you book. A screenshot from the host tells you more than the word “wifi” in a listing. If you’ll be on video calls, check the upload speed too.
- Have a backup. A local SIM with a data package covers you when the wifi drops.
- Keep a café or restaurant in mind. Knowing where you can sit with a laptop for an hour saves a lot of stress.
- Mind the time zone. Costa Rica stays on UTC-6 all year and never changes its clocks. That lines up with Colorado in the US summer and puts us an hour ahead of Colorado in the winter.
- Plan around the holiday crowds. More on that below.
If you’d rather skip the guesswork, Casa Colorado is ours, and it has the fiber connection in the table above.
FAQ
Is the internet in Tamarindo good enough to work remotely?
Yes, in most places. Home fiber is available in town, and Numbeo’s Tamarindo average for a 60 Mbps or faster plan was $59 a month in October 2026. Hotels and hostels slow down when they’re full, so if you work online, rent a house and ask the host for a speed test before you book.
Which cell carrier is best in Tamarindo?
All three Costa Rican carriers work well in town. kölbi has the widest coverage in the country, so it’s the one we’d pick if you’re also driving to the mountains or national parks.
Should I get a local SIM, an eSIM, or use my US plan?
For a short trip, your US plan or a travel eSIM is easiest. For longer stays, a local prepaid SIM is usually cheapest. A kölbi package with 10 GB for 30 days was ₡5,000 (about $11) in October 2026. Bring your passport to register a physical SIM.
Where can I buy a SIM card near Tamarindo?
The closest kölbi branch is in Plaza Huacas, in nearby Huacas. Claro has a store at Liberia airport and another in Santa Cruz. Google Maps shows the Liberty store in Tamarindo as permanently closed, so sort out your SIM or eSIM before you get to town if you can.
Do people in Costa Rica use WhatsApp?
Almost everyone. A 2024 University of Costa Rica study found that 98 percent of Costa Ricans with a cell phone use WhatsApp. Businesses use it too, so install it before your trip.
Is Starlink available in Tamarindo?
Starlink sells residential service in Costa Rica, and it’s a good option for houses outside town where fiber doesn’t reach. In Tamarindo itself, fiber is usually the simpler choice if your street has it.
