Costa Rica coverage: what to expect outside San José
Kolbi (the state telecom, ICE) and Claro provide the widest coverage across Costa Rica's varied terrain. San José and the Central Valley have solid 4G/5G. Coverage thins in specific pockets worth knowing about before you go.
- Arenal Volcano (La Fortuna): solid 4G in town and at the main viewpoints — hot springs resorts and hanging bridge parks are all covered.
- Monteverde cloud forest: 4G in Santa Elena town and at the reserve entrance; the hanging bridges trails themselves have patchy 3G/4G.
- Manuel Antonio: 4G at the town and national park entrance; interior trails vary with proximity to the coast.
- Nicoya Peninsula (Tamarindo, Nosara, Santa Teresa): 4G on main roads and in town centers; more remote beach-access tracks may drop to 3G.
- Corcovado National Park (Osa Peninsula): 4G at Puerto Jiménez gateway town; the park interior is largely offline — download maps first.
- Tortuguero: 4G in the village (boat-access only); the turtle-nesting beach itself is offline.
Is it worth getting an eSIM for Costa Rica, or buying a local SIM?
For most travelers, yes. Costa Rica doesn't have the same airport tourist-SIM culture as somewhere like Thailand — Kolbi and Claro counters exist at Juan Santamaría (SJO) but queues and passport requirements make it slower than installing an eSIM on Wi-Fi before you fly. An eSIM also means you land already connected for your rental car GPS or ride-share pickup.
Can you use your US phone in Costa Rica?
Yes, if it is unlocked. You have three options: your US carrier’s roaming pass, a local Kölbi, Claro or Liberty SIM bought with your passport at San José airport, or a travel eSIM. Roaming passes cost around $10–$12 a day, as our AT&T and Verizon comparisons show. A local SIM is the cheapest per gigabyte, especially for long stays. A travel eSIM is the convenient middle: installed before you fly, connected to Claro when you land, with your US number still active for calls and texts.
| Flysimio Costa Rica eSIM | Local SIM | US roaming pass | |
|---|---|---|---|
| Set up | Before you fly | Airport counter, passport | Automatic |
| Cost | One price for the plan | Cheapest per GB | About $10–$12 a day |
| Network | Claro | The carrier you buy from | Your carrier’s partner |
| US number | Stays active on your regular SIM | Removed while the local SIM is in | Yes |
| Best for | Trips up to two weeks | Long stays and heavy data use | Very short trips |
Do you turn off your primary SIM? You do not have to: keep it on for calls and texts with data roaming off. The eSIM settings guide walks through it on iPhone and Android.
Frequently asked questions
What is the best SIM card for tourists in Costa Rica?
For a trip up to about two weeks, a travel eSIM is the simplest. For longer stays or heavy data use, a local Kölbi or Claro SIM bought at the airport with your passport is cheaper per gigabyte.
Can I use my US cell phone in Costa Rica?
Yes, if it is unlocked. Add a travel eSIM for data and keep your US line on for calls and texts with data roaming off, or use your carrier’s roaming pass at around $10–$12 a day.
Do I turn off my primary SIM when using an eSIM in Costa Rica?
No need. Keep it on with data roaming off so you still receive calls and texts; the eSIM handles the data.
What is the best eSIM for Costa Rica?
For most trips a fixed-data plan of 5–10 GB is the right product — Costa Rica's networks are fast enough that unlimited passes are rarely necessary. Airalo and Holafly both sell unlimited-only for Costa Rica, at $89.00 and $99.90 for 30 days respectively.
Does the eSIM work at Arenal Volcano and La Fortuna?
Yes. La Fortuna town and the main Arenal viewpoints have solid 4G on Kolbi and Claro. Hot springs resorts and hanging bridge parks near La Fortuna are all covered.
Is there coverage in Monteverde cloud forest?
Yes in Santa Elena town and at the Monteverde Cloud Forest Reserve entrance. The hanging bridges trails themselves have patchy 3G/4G — download offline maps before entering.
How much data do I need for two weeks in Costa Rica?
For typical use — maps, messaging, and social media — 5 GB is comfortable for one to two weeks. If you're covering more ground (Arenal, Monteverde, Manuel Antonio, and the Nicoya beaches) or streaming occasionally, size up to 10 GB.
Does the eSIM work at Manuel Antonio beach?
Yes. Manuel Antonio town and the national park entrance have 4G. Interior trail coverage varies with proximity to the coast.
Is Costa Rica eSIM cheaper than Airalo?
Yes for normal use: Airalo sells Costa Rica as unlimited-only, so any of our fixed plans costs less than its 30-day pass. If you specifically want unlimited data, compare our largest fixed tier against Airalo's unlimited 30-day plan ($89.00) or Holafly's ($99.90); pick based on whether you'll actually use more than 20 GB.
Do I need to activate before I fly to Costa Rica?
No. You have six months from purchase to activate — the validity period only starts counting down when your eSIM first connects to a network in Costa Rica.
