Best eSIM for 🇨🇷 Costa Rica

Okay, you're flying to Costa Rica in 48 hours and need data. Forget buying a SIM at the airport; it's a rip-off. You need an eSIM.

Who Actually Has Service in Costa Rica?

You've got three main players down there: Kolbi (the state-owned one), Movistar, and Claro. On the ground, Kolbi generally has the best coverage, especially if you're heading outside the San Jose metro area. You'll find dead zones in really remote mountain areas or if you're planning on island-hopping, but for the main tourist routes, it's solid. Movistar and Claro are okay in cities but can get spotty fast once you hit the Pacific coast jungles or the Talamanca Mountains. Stick with Kolbi's network if you can.

What Does Data Actually Cost?

You're looking at roughly $15 to $25 for a plan with 5-10 GB of data that'll last you 7-15 days. This is for an eSIM you buy online before you leave. Some providers might offer slightly cheaper deals, but they often come with way less data or shorter validity. Don't get suckered into a "unlimited" plan that throttles you to death after 2GB.

Activation Gotchas You Need to Know

This is where people mess up. Don't activate your eSIM until you're on the ground in Costa Rica. Some providers flag international SIMs activated elsewhere. Turn on airplane mode before you scan the QR code. Once scanned and installed, then turn off airplane mode. If you have a dual-SIM phone, especially one made for the Chinese market with physical dual SIMs, make sure you’re installing the eSIM on the correct profile and not accidentally disabling your primary SIM. The QR code is often only valid for a short window, so have it ready to scan the moment you land.

The One Costa Rican Gotcha: Hotspot Blocking

Some smaller Costa Rican operators, and even sometimes Kolbi depending on the specific plan, might block or heavily restrict tethering/hotspot usage. This means using your phone as a Wi-Fi source for your laptop or tablet might not work. It's not a universal rule, but it's common enough that you should be prepared to buy a separate local SIM if you absolutely need reliable hotspot access. If you're just using your phone, you'll be fine.

Quick Costa Rica eSIM Questions

Can I buy an eSIM after I land? Yes, but it's usually more expensive and the selection is limited. Buying before you go saves hassle and potentially money.

Will my international plan work? Some do, but roaming charges can be brutal. Buying a local eSIM is almost always cheaper for decent data amounts.

Is 5GB enough for a week? For light use like maps and messaging, yes. If you stream video or download large files, you'll want 10GB or more.

What if my phone doesn't support eSIM? You'll need to buy a physical SIM card upon arrival. Look for Kolbi kiosks outside the main airport terminals for better prices than inside.
