Stop guessing, start with a number
How much data for Costa Rica
Costa Rica burns more data than a European trip of the same length, for one specific reason. Here is what to budget and why the usual advice runs low.
How much data your Costa Rica trip needs by length and habits
| Trip style | 5 days | 10 days | 14 days | 30 days |
|---|---|---|---|---|
| Maps, WhatsApp, the odd booking | 1.5GB | 3GB | 4GB | 8GB |
| Plus photos, stories, some video | 4GB | 8GB | 11GB | 22GB |
| Plus laptop hotspot and calls | 9GB | 18GB | 25GB | 55GB |
Assumes wifi at your accommodation most nights, offline maps downloaded before you drive, and no video streaming over cellular. If you plan to stream, add 0.7GB per hour in standard definition and 3GB per hour in HD.
Read the row that describes you honestly rather than the one that describes your intentions. Almost everyone who says they will only use maps ends up posting photos, and almost everyone who buys 1GB tops up.
The safe move on a first Costa Rica trip is the middle row plus a margin. If two weeks of social use is 11GB, buy a plan around 10GB and know you can top up in the app without a new QR code. That lands you at $24.35 on Yesim or $34.00 on Airalo rather than $47.99 for a 20GB plan you will not finish.
The Costa Rica map tax why the usual estimates run low
Navigation is supposed to be the cheapest thing your phone does. In Costa Rica it is not, and this is the single most useful thing on this page.
Google Maps uses about 5 to 10MB an hour when the connection is steady. It uses considerably more when the connection keeps dropping and recovering, because every recovery triggers a fresh tile fetch, a re-route and a traffic refresh. Costa Rican mountain roads, the stretch from the Interamericana up to Monteverde, the run south past Uvita, the whole Nicoya interior, do exactly that all day long.
Add Waze, which most Costa Rican drivers use and which is chattier still, and a self-drive week can spend a gigabyte on navigation alone rather than the 100MB the same driving would cost in Spain.
The fix is free. Download the offline map for the whole country before you leave home wifi. In Google Maps, search Costa Rica, tap the name, then Download. It is a few hundred megabytes on wifi and it removes the largest unpredictable line item from your data budget. Do it even if you buy an unlimited plan, because it also means the map still works where no travel eSIM has signal.
What each app costs per hour the numbers behind the estimate
| App | Roughly per hour | What that means on a trip |
|---|---|---|
| Google Maps, steady signal | 5–10MB | Negligible |
| Google Maps or Waze, patchy signal | 40–80MB | The Costa Rica tax. A self-drive day can hit 500MB. |
| WhatsApp text and voice notes | 10–20MB | Negligible, and it is how the whole country communicates |
| WhatsApp video call | 0.3GB | Half an hour a day for two weeks is about 2GB |
| Instagram or TikTok scrolling | 0.7GB | The largest single line item for most travelers |
| Uploading 20 photos | 0.1GB | Small individually, adds up daily |
| Uploading a 1-minute 4K video | 0.35GB | The thing that quietly empties a 5GB plan |
| Zoom or Meet, video on | 0.9GB | Three calls a day is a 3GB day on its own |
| Laptop hotspot, ordinary work | 0.4GB | A working day is 2–3GB with browsing and syncing |
| Netflix, standard definition | 0.7GB | Download at the hotel instead |
| Netflix, high definition | 3GB | Never do this on cellular |

Three travelers, three real numbers find yourself here
Seven nights at an all-inclusive with strong wifi, two guided tours, no rental car. Maps at the airport, WhatsApp to the family, a hundred photos uploaded from the room over wifi. Buy Yesim 3GB at $9.04 and finish the trip with data left over.
Arenal, Monteverde, Manuel Antonio, back to San José. A rental car, Waze running six hours a day on roads that keep dropping signal, daily stories, a few video calls home. Buy Airalo 10GB at $34.00 or Yesim's at $24.35 and download the offline map anyway.
Four to six hours a day tethered to a laptop, two video calls most days, evenings on the phone. Fixed plans stop making sense here. Buy GigSky's 15-day 3.5GB daily bundle at $36.49, twice, or compare the unlimited options.
What to buy once you have your number cheapest match at each size
| You need | Cheapest | Price | Runner-up |
|---|---|---|---|
| 1GB | Yesim | $4.99 / 30 days | GigSky $6.99 / 7 days |
| 3GB | Yesim | $9.04 / 30 days | GigSky $16.49 / 15 days |
| 5GB | Yesim | $15.07 / 30 days | GigSky $21.99 / 30 days |
| 10GB | Yesim | $24.35 / 30 days | Airalo $34.00 / 30 days |
| 20GB | Yesim | $36.52 / 30 days | Airalo $40.50 / 30 days |
Yesim is cheapest at every size and carries a suspended Trustpilot score, which we flag every time it appears. The runner-up column is what to buy if that matters to you. Checked September 2, 2026.
Buy roughly your estimate, not double it. Every brand here lets you top up mid-trip in the app, so the cost of underestimating is a two-minute purchase and the cost of overestimating is money you do not get back.

How much data do I need for two weeks in Costa Rica?
Around 8 to 11GB for ordinary use: maps, messaging, photos, social and a few video calls, with wifi at your accommodation most nights. A 10GB plan is the right size for most two-week trips, and every provider here lets you top up if you run short.
Why does Costa Rica use more data than other destinations?
Navigation. On mountain and coastal roads the signal drops and recovers constantly, and every recovery makes Maps or Waze refetch tiles, re-route and reload traffic. A self-drive day can spend 500MB on navigation that would cost 50MB in a country with continuous coverage. Downloading the offline map before you fly removes most of it.
Is 5GB enough for Costa Rica?
For a week of light use with hotel wifi, yes comfortably. For two weeks with photos and social, it is tight and you will probably top up. For anything involving a laptop hotspot, no.
Do I need unlimited data in Costa Rica?
Only for hotspot-heavy remote work, or if you genuinely refuse to think about data. A two-week trip at 11GB costs $24.35 to $34.00 on a fixed plan against $50.50 or more for two weeks of unlimited. The comparison is here.
Does WhatsApp use a lot of data in Costa Rica?
Messages and voice notes barely register, at 10 to 20MB an hour. Video calls are the expensive part, at roughly 0.3GB an hour. Since WhatsApp is how Costa Rican lodges, drivers and tour operators all communicate, budget for messaging generously and for video calls carefully.
Can I top up mid-trip if I run out?
Yes, on every provider we compare, inside their app and without a new QR code or a new eSIM profile. That is why we recommend buying roughly your estimate rather than padding it: topping up costs two minutes, overbuying costs money you cannot recover.
Ten gigabytes fits most Costa Rica trips
Airalo's 10GB plan is $34.00 for 30 days on Claro and Liberty, named on the product page, with in-app top-ups if your two weeks turn out heavier than you thought.
