Looking for the best eSIM for Costa Rica? Here’s how to land in San Jose with working data already on your phone, what coverage to expect from the surf towns to the cloud forest, and how US Mobile’s roaming and Travel Pass options stack up before you fly.
Why an eSIM beats a local SIM in Costa Rica
Costa Rica packs a ridiculous amount of variety into a small country. You might surf Tamarindo in the morning, drive through Monteverde cloud forest by afternoon, and watch turtles nest on the Caribbean coast after dark. Through all of it, working mobile data is what keeps the logistics from falling apart. Maps, ride apps, last-minute lodge bookings, the WhatsApp message to your shuttle driver who’s “five minutes away” for the third time.
Here’s the thing. You could hunt down a Kolbi SIM at the airport, dig out the tray tool, and hope the kiosk takes a card. Or you could land with a line already live. An eSIM downloads over Wi-Fi as a digital profile, so there’s no chip to insert and nothing to wait for in the mail. If you’ve never set one up, our walkthrough on how to activate an eSIM covers it in about two minutes. New to the whole idea? Start with what an eSIM card actually is.
The best eSIM for Costa Rica: US Mobile
The reason a US Mobile eSIM works well for a Costa Rica trip is simple. You don’t manage a separate travel-only profile or pick a local carrier blind. Your US number rides along, and you roam on local towers the moment you arrive. Two ways to do it, depending on your plan.
Already on Unlimited Premium
You’re basically set. Unlimited Premium includes 20GB of international roaming data, plus 200 minutes of calling and 250 texts, across 180+ destinations (Costa Rica included). Flip on data roaming when you land and go.
On a different plan
Add a Travel Pass for Costa Rica in the US Mobile app. $15 gets you 1GB of data with 150 minutes and 150 texts. $30 gets you 5GB with 500 minutes and 500 texts. A few taps, no trip to a store.
| Option | Data | Calls / texts | Best for |
|---|---|---|---|
| Unlimited Premium (included roaming) | 20GB across 180+ destinations | 200 min / 250 texts | Anyone already on Premium, or longer trips |
| Travel Pass $15 | 1GB | 150 min / 150 texts | Short trips, light data use |
| Travel Pass $30 | 5GB | 500 min / 500 texts | Heavier maps, photos, and uploads |

How to get connected in Costa Rica before you fly
The setup depends on your plan, but the whole thing happens on your couch at home, not at the airport.
Check what international data you already have
Open the US Mobile app and look at your plan type and your included international data. If you’re on Unlimited Premium, you’ve got 20GB of roaming across 180+ destinations, and Costa Rica is covered. If your included data handles the trip, you’re done. Nothing else to buy.
Add a Travel Pass if you need more
Not on Unlimited, or want more high-speed data than what’s bundled? Head to US Mobile’s international roaming page, select Costa Rica, and add a Travel Pass in the app. $15 for 1GB or $30 for 5GB. It takes a few taps.
Make sure your phone is ready
Confirm your phone supports eSIM (most 2020-and-newer devices do), check that it’s carrier-unlocked, install the eSIM profile if prompted, and you’re set.
Land and connect
Once you’re on the ground in Costa Rica, go to Settings > Cellular, turn on your international line, and make sure data roaming is enabled. Your phone connects to the strongest available local network automatically. No airport kiosks, no guessing which Costa Rican carrier to pick.
This is the part travelers tend to underestimate. PCMag reviewed the US Mobile roaming process and called it one of the easiest ways to get connected abroad.
Coverage you can actually expect
San Jose, Liberia, Manuel Antonio, La Fortuna (Arenal), and Tamarindo all have reliable 4G. The Osa Peninsula, deep Monteverde forest, and Caribbean towns like Puerto Viejo run patchier. The move: download offline maps for rainforest hikes and remote beach days, then lean on your eSIM data in towns and at your hotel.
Try US Mobile eSIM free for 30 days

Frequently Asked Questions
What’s the best eSIM for Costa Rica?
For most travelers it’s a US Mobile eSIM. If you’re on Unlimited Premium, you already get 20GB of international roaming data across 180+ destinations, including Costa Rica, so you just turn on data roaming when you land. On other plans, add a Travel Pass in the app: $15 for 1GB or $30 for 5GB.
How much does eSIM data cost for Costa Rica?
With US Mobile, Unlimited Premium includes 20GB of roaming at no extra cost. If you need a separate pass, a Travel Pass is $15 for 1GB (plus 150 minutes and 150 texts) or $30 for 5GB (plus 500 minutes and 500 texts). You buy it in the app before you go.
Will I have signal in the rainforest?
Deep in national parks and reserves, signal drops off. Most eco-lodges and hotels have Wi-Fi, so you’ll be connected back at base. For day hikes, download maps and anything else you need ahead of time.
Is 5G available in Costa Rica?
Costa Rica is still primarily 4G/LTE. 5G rollout is in early stages and limited to parts of San Jose. Your eSIM will work on 4G, which is plenty for maps, messaging, and social media.
