Holafly Costa Rica eSIM: Our Firsthand Review After Living There + Code THEDUFRESNES (Up to 30% Off)
Last Updated:
The working Holafly discount code for Costa Rica is THEDUFRESNES. It takes 5% off the Costa Rica eSIM, plus 10% off monthly Plans and up to 30% off annual Plans (Holafly's ~20% annual promotion stacked with the 10% code). Unlimited uses, verified August 2026.
This isn't a page written from a hotel-room search. We lived in Costa Rica — based in Sámara on the Guanacaste coast, where we built and ran our vacation rentals — so we know the country. And when we traveled around it and across its borders, Holafly is what we used to stay connected. Here's the honest version: where it shines, where the terrain fights any network, and how to pick the right plan.
We lived here — so here's the honest version
Let's be straight about our experience, because that's the point of this page. When we lived in Sámara, day to day we were on local phone plans, like most residents. Where we actually leaned on Holafly was when we traveled — heading down to the Santa Teresa area and out to Uvita on the Pacific coast, and crossing out of the country into Nicaragua and Mexico. At that time we bought a country-specific eSIM for each place we went.
That's exactly the situation a visitor to Costa Rica is in: you're moving around, you don't want a local contract, and you want data that just works when you land and when you travel between spots. On that front, it did the job for us — connected on arrival, no SIM shop, no passport handed over at a kiosk.
Costa Rica coverage: the terrain is the story
Here's the thing about connectivity in Costa Rica that a spec sheet won't tell you: the geography dictates the signal. Holafly runs on major local networks with 4G/LTE and 5G where available, and Holafly itself is upfront that coverage is excellent in urban areas but weaker in mountains and deep countryside. Having lived there, we can confirm that's the real pattern:
- Towns and the popular coast — the Guanacaste beach towns, the areas around Santa Teresa and Uvita — solid and reliable for maps, ride apps, and staying in touch.
- Mountains and remote stretches — the cloud forest, the winding interior roads, the truly off-grid corners — this is where any network thins out, Holafly included. It's not a Holafly quirk; it's Costa Rica's terrain. Download offline maps before you head into the hills.
If your trip is beach towns, Arenal, Manuel Antonio, the Nicoya Peninsula — the places most visitors actually go — you'll be well covered. Plan for gaps only if you're going deep into the mountains.
Crossing borders: what we'd do differently now
When we crossed from Costa Rica into Nicaragua and Mexico, we bought a separate country eSIM for each — which worked, but meant buying again at each border. If you're doing a multi-country Central America trip today, there's a simpler way: a regional eSIM or Holafly Plans covers the region on one plan, reconnecting automatically as you cross. For a single Costa Rica trip, the country eSIM is the right pick; for a border-hopping itinerary, look regional.
Holafly Costa Rica eSIM prices (with THEDUFRESNES)
An honest heads-up: Costa Rica is priced above Holafly's standard destination rate — it's one of the pricier country eSIMs. Unlimited data, priced by the day; the code takes 5% off.
| Plan length | Standard price | With THEDUFRESNES (5%) |
|---|---|---|
| 3 days | $19.90 | $18.91 |
| 5 days | $28.90 | $27.46 |
| 7 days | $36.50 | $34.68 |
| 10 days | $39.50 | $37.53 |
| 15 days | $50.50 | $47.98 |
| 30 days | $95.90 | $91.11 |
Prices in USD, verified at Holafly checkout August 2026. Any duration from 1 to 90 days is available; the rows are reference points. Figures change — we re-verify monthly.
If you're staying a while or traveling beyond Costa Rica, Holafly Plans (unlimited data across 160+ destinations, up to 30% off annual with the code) can work out better than a long single-country plan.
What travelers say about Holafly in Costa Rica
The sentiment we see from travelers on Reddit and traveler forums matches what we lived: strong, easy connectivity in the towns and along the coast, the convenience of landing already online, and the honest caveat that the mountainous, jungly terrain challenges every provider's signal in remote areas. The other recurring note is the trade-off we'd flag ourselves — Costa Rica is a premium-priced destination and "unlimited" carries a fair-use policy, as every unlimited plan does. For the ease of arriving connected and not chasing a local SIM, most visitors find it worth it.

Costa Rica eSIM FAQ
Does Holafly work well in Costa Rica?
Yes in towns and along the popular coast — where most visitors spend their time — it's strong and reliable. In the mountains and deep countryside, signal thins out, but that's the terrain challenging every network, not a Holafly-specific issue. We lived there and traveled it, so this is firsthand.
How much is the Holafly Costa Rica eSIM?
Unlimited-data plans run from $19.90 for 3 days to $95.90 for 30 days — Costa Rica is priced above Holafly's standard destination rate. With code THEDUFRESNES you get 5% off, so a 7-day plan is $34.68 instead of $36.50.
Do I need a local SIM in Costa Rica?
No. A Holafly eSIM installs by QR code before you fly and is live when you land — no SIM shop, no passport registration. It's the easiest option for a visitor moving around the country.
Will it work in the mountains or cloud forest?
Coverage weakens in mountainous and remote areas — true of any provider in Costa Rica's terrain. Download offline maps before heading into the hills. In beach towns and populated areas you'll be well connected.
Costa Rica plus Nicaragua or Panama — one eSIM?
For a multi-country Central America trip, a regional eSIM or Holafly Plans covers the region on one plan and reconnects across borders — simpler than buying a separate country eSIM at each border (which is what we did years ago).
Can I hotspot with the Costa Rica eSIM?
Destination eSIMs allow around 1 GB/day of sharing. For heavy tethering or remote work, Holafly Plans Unlimited includes unlimited hotspot.
Is THEDUFRESNES a working Holafly code?
Yes — our official ambassador code, verified August 2026. 5% off destination eSIMs like Costa Rica, 10% off monthly Plans, and up to 30% off annual Plans (Holafly's 20% annual promotion plus the 10% code).
Bottom line
We lived in Costa Rica, built a life on the Guanacaste coast, and traveled it end to end — so we'll give it to you straight: a Holafly Costa Rica eSIM is a genuinely easy way for a visitor to stay connected in the towns and along the coast where you'll spend most of your time, with the honest caveat that the mountains challenge every network and the country eSIM is priced at a premium. For arriving connected and skipping the local-SIM hassle, it's an easy call. Either way, THEDUFRESNES saves you at checkout.
