Best reviewed, least transparent

Saily in Costa Rica

The NordVPN team runs the most trusted eSIM brand on this site. In Costa Rica it is also the only one that will not tell you whose towers you are renting.

Quick answerSaily has the best support record here: Trustpilot 4.7 from 30,290 reviews, run by the NordVPN team. Costa Rica costs $36.99 for 10GB over 30 days, and there is no unlimited plan for the country. Why it is not our top pick: Saily will not say which Costa Rican network it uses. Checked September 2, 2026.

There is no way to soften that fourth column. In Costa Rica, Saily is beaten on price at every single size, usually by both Airalo and Yesim. In Greece the same brand is a bargain; here the local wholesale deal clearly costs it more. Anyone who tells you Saily is the cheapest Costa Rica eSIM has copied a price list from another country.

Saily will not name its Costa Rican network and that matters here

Airalo, Yesim, GigSky and Holafly all publish their Costa Rica partners. Saily's Costa Rica product page names none. We checked the page, the FAQ and the coverage documentation on September 2, 2026 and found no Costa Rican operator identified anywhere.

In a country with one national network you could shrug at that. Costa Rica has three, they diverge sharply outside the Central Valley, and choosing between them is the single most consequential decision a traveler makes here. Not being able to check which one you are buying is a real disadvantage, not a pedantic one.

To be fair to Saily: it almost certainly rides the same Claro and Liberty wholesale that everyone else does, since Kölbi does not sell that access to travel eSIMs. We are not going to state that as fact when the company itself will not, and neither should any guide that has not seen it confirmed. Why the Kölbi gap matters is here.

One column is Saily's and it is a strong one. If you have ever had a travel eSIM fail on a Sunday and discovered that support is a chatbot, the 4.7 score is not an abstraction. The question is whether it is worth $12.64 over Yesim and $2.99 over Airalo on a 10GB plan, on a trip where you also cannot look up the network. For most Costa Rica routes we think it is not, and we say so.

Why people pay the Saily premium anyway and when they are right

Support that answers. Nord Security runs this the way it runs NordVPN: real refunds, real humans, a process with a paper trail. Across 30,290 reviews the 4.7 average is the highest on this site by a distance, and it is earned rather than farmed.

One account for a multi-country year. If Costa Rica is one stop on a longer Latin America run, Saily's regional bundles let you keep a single app and a single billing relationship. The multi-country page compares that against buying two local plans.

Where it loses, plainly. Beaten on price at every size for Costa Rica. No unlimited product for the country. No published network. If your trip is a straightforward two weeks in Costa Rica, those three lines add up to a clear no, and Airalo does the same job for less.

Buying and activating Saily the short version

  1. Buy on the Saily site or app at home on wifi. Both track the same for us and the price is identical.
  2. Install the profile early and leave the line switched off. Validity starts on first connection in Costa Rica, not at purchase.
  3. On landing: Saily line on for data, home line on for calls with its data roaming off.
  4. If it does not attach, try manual network selection and work through the operators the phone offers. Since Saily does not publish its partners, you are testing rather than choosing. Full setup guide.

Buy it or skip it the honest split

Buy Saily if

Support quality outranks price for you, and 4.7 from 30,290 reviews is what you want behind a plan you depend on.

Costa Rica is one leg of a longer Latin America trip and you want one app for all of it.

You have used Saily elsewhere, it worked, and familiarity is worth $3. That is a real reason.

Skip Saily if

You want to know your network: Airalo publishes Claro and Liberty and costs less.

You want unlimited: Saily does not sell it for Costa Rica.

Price matters at all: it loses every size row, sometimes by twelve dollars.

Questions on Saily in Costa Rica

Which network does Saily use in Costa Rica?

Saily does not say. We checked its Costa Rica product page, FAQ and coverage documentation on September 2, 2026 and found no operator named. It is very likely Claro or Liberty, because Kölbi does not sell wholesale roaming to travel eSIMs, but likely is not published and we will not print it as fact.

Does Saily have an unlimited plan for Costa Rica?

No. Saily's unlimited products are global bundles with a 30GB ceiling behind the word, and there is no Costa Rica unlimited plan. If you want unlimited for this country, Airalo publishes a 3GB/day cap and Holafly sells uncapped phone data with a 1GB/day hotspot limit.

Is Saily worth more than Airalo in Costa Rica?

For most trips, no. Airalo is $2.99 cheaper on 10GB, $7.49 cheaper on 20GB, publishes its networks and sells an unlimited plan. Saily wins on Trustpilot score and on refund track record, which matters if you are the kind of traveler who wants a company to answer the phone.

When does a Saily plan start counting?

On first connection to a network in Costa Rica, not at purchase. Install at home and land connected.

Can I hotspot on Saily?

Yes, on all its Costa Rica plans, drawing from the same fixed allowance. There is no separate tethering cap because there is no unlimited plan for it to apply to.

Does Saily work in the Osa Peninsula and Tortuguero?

Assume not, the same as every travel eSIM. Those regions lean on Kölbi and no travel eSIM roams on it. This is exactly where the unpublished-network issue bites: with Airalo you can at least check a Claro map beforehand. What to do instead.
