Costa Rica Connectivity for Anglers
Best eSIM for Costa Rica: Roamless vs Airalo, Saily and GigSky
A Costa Rica fly-fishing trip is supposed to pull you away from your phone—not leave you unable to contact your driver, open your directions or tell the lodge that your flight was delayed.
That is the real reason to consider a travel eSIM. It is not about staying glued to social media while standing beside a jungle river. It is about having data available when it solves an actual problem.
I have used Roamless during our last two winters of travelling in Costa Rica, and it has effectively become my primary mobile connection. Airalo, Saily and GigSky take somewhat different approaches, so this comparison looks at which type of traveller each service may suit—not simply which company has the loudest advertisement.

Quick answer
My personal choice is Roamless because I have used it through two Costa Rica travel seasons, can keep credits available between trips and have received useful support when automatic network selection did not connect properly.
Airalo is a widely recommended prepaid option, Saily offers straightforward packages and added security tools, while GigSky is worth considering for travellers who want to test a small amount of data before purchasing a larger plan.

Why an eSIM Helps on a Costa Rica Fishing Trip
An eSIM is a digital SIM profile installed on a compatible phone. Instead of removing your regular SIM card and buying a physical Costa Rican one, you install a travel plan and use it for mobile data.
For an angler travelling between Liberia Airport, Bijagua, Upala and Río Niño, mobile data can help with:
- Contacting a tourism driver or rental company
- Opening Waze or another navigation app
- Telling the lodge about an arrival delay
- Using WhatsApp when Wi-Fi is unavailable
- Checking airline or baggage updates
- Accessing reservation confirmations
- Creating a hotspot for a second device when supported
Most travel eSIMs are primarily data services. Calls and traditional text messages may not be included unless the provider specifically offers them. Apps such as WhatsApp, Messenger and Signal can still work through mobile data.
Before you buy anything
Confirm that your phone supports eSIM technology and is unlocked. A travel eSIM cannot fix carrier restrictions, incompatible hardware or a phone that has been locked to another provider.
My Experience Using Roamless in Costa Rica
Roamless is the one service in this comparison that I can discuss from repeated personal use.
I downloaded and activated it before our Costa Rica travels and have now used it through three winters. I no longer maintain a conventional carrier contract, so Roamless has become my primary mobile connection rather than something that sits unused beside another expensive plan.
The setup has been simple, and the same global eSIM can remain installed as I move between supported countries. Roamless offers both prepaid data plans and a pay-as-you-go credit system. That flexibility is useful when I want connectivity available without committing to a large package that may expire before I use it.
It has not connected perfectly everywhere in Costa Rica.
There have been locations where automatic network selection did not find the best available connection. When that happened, support explained which supported network to select manually. That practical support is one of the main reasons I continue using the service.
Data has sometimes felt expensive, especially when compared with buying a local prepaid SIM. However, Roamless has continued changing and expanding its plan options, so travellers should compare the current fixed plans with the pay-as-you-go rate rather than relying on an old price screenshot.
My honest position: when you are staying in the jungle, you do not need to be connected every second. Use lodge Wi-Fi when it is available. Save mobile data for navigation, transportation, messages and the moments when connectivity actually matters.

Roamless vs Airalo vs Saily vs GigSky
| Provider | Plan style | Strongest use | Watch for | Our relationship |
|---|---|---|---|---|
| Roamless | Pay as you go or fixed plans | Ongoing travellers who want one installed global eSIM | Compare the current data rate and supported networks | Personally used; affiliate link |
| Airalo | Prepaid destination and regional packages | Travellers who want a familiar package-based service | Check validity, top-up availability and network details | Not personally tested; affiliate link |
| Saily | Prepaid data packages | Simple setup, hotspot use and added security features | Most travel plans are data-focused; confirm calling needs | Not personally tested; affiliate link |
| GigSky | Prepaid destination plans with trial availability | Testing compatibility before purchasing more data | A small trial allowance will not support heavy use | Not personally tested; no affiliate link |
Airalo: The Widely Recommended Alternative
Airalo is one of the names I see recommended most often in online travel conversations, including Costa Rica discussions on Facebook. That does not automatically make it the best service in every rural location, but it does make it one of Roamless’s most visible direct competitors.
Airalo sells prepaid eSIM packages for individual countries, regions and broader global travel. For someone taking a defined vacation, that model is easy to understand: choose a data allowance, check the validity period and purchase before travelling.
Airalo may suit you if:
- You want a conventional prepaid data package.
- You prefer choosing a country or regional plan in advance.
- You want to manage usage and top-ups through an established app.
- You have compared the current Costa Rica plan with your other options.
Saily: Simple Packages With Extra Security Tools
Saily also uses a prepaid package model. Its Costa Rica plans support mobile data, top-ups and hotspot sharing, while the app promotes additional tools such as web protection, tracker blocking and virtual-location features.
Those extras may appeal to travellers regularly connecting through hotels, airports and unfamiliar Wi-Fi networks. They should not distract from the main comparison, however: first check the data allowance, validity period, local-network access and total price.
Saily may suit you if:
- You want a defined prepaid plan.
- You expect to share data through a mobile hotspot.
- You value additional privacy and browsing tools.
- You want automatic activation after arriving in Costa Rica.
GigSky: A Useful Fourth Option
GigSky offers Costa Rica eSIM coverage and promotes a small trial-data option. That can be useful for checking whether the service activates correctly on your device before committing to a larger purchase.
A trial allowance is meant for testing—not navigation, uploading videos or running a laptop hotspot for an entire trip. Review the paid packages if GigSky works well on your device.
We do not currently have an affiliate relationship with GigSky. It remains in the comparison because leaving out a relevant competitor would make this less useful to the reader.
Visit GigSkyCosta Rica Coverage Is About the Local Network
An eSIM company does not build its own cell towers throughout Costa Rica. It connects through agreements with local mobile networks.
Costa Rica’s principal mobile operators are Claro, Kölbi and Liberty. Coverage and performance vary by operator, terrain and exact location. A provider that works well in San José or Liberia may behave differently near a rural river, behind hills or under dense vegetation.
That is why no honest eSIM comparison should promise uninterrupted jungle service.
The practical fix
If your eSIM does not connect automatically, do not immediately assume it has failed.
- Confirm the eSIM line is turned on.
- Enable data roaming for the travel eSIM.
- Confirm the travel eSIM is selected for mobile data.
- Toggle airplane mode or restart the phone.
- Check automatic network selection.
- Ask support which available network to select manually.
Roamless normally uses automatic selection, but manual network selection helped me in locations where the phone did not choose the best supported connection on its own.
Before travelling north from Liberia, download offline maps and save your lodge, transportation and reservation details locally. Mobile service should support your plan—not be the only thing holding it together.
Our Liberia Airport to Upala and Río Niño Lodge guide explains the familiar driving route and why travellers should not blindly accept every shortcut suggested by a navigation app.
How Much Data Does an Angler Need?
The best plan is not necessarily the one with the largest number printed on it. Choose based on what you will actually do.
| Traveller type | Typical mobile use | Plan approach |
|---|---|---|
| Light user | Messages, maps and confirmations | Small package or pay as you go |
| Regular traveller | Navigation, browsing, email and photos | Moderate prepaid package |
| Working traveller | Hotspot, uploads and online work | Larger plan with hotspot support |
| Wi-Fi-first guest | Mobile data only during travel days | Flexible credit or smaller plan |
Video consumes data quickly. Automatic photo backups, app updates and laptop hotspots can also drain a smaller package without you noticing. Turn off unnecessary background usage before relying on mobile data in a rural area.
Set Up Your eSIM Before Flying
- Check compatibility. Confirm that your exact phone model supports eSIM installation.
- Confirm the phone is unlocked. Contact your carrier if you are unsure.
- Install on reliable Wi-Fi. Do not wait until you are stranded without data.
- Label both lines. Use names such as “Primary” and “Costa Rica Data.”
- Choose the data line. Select the travel eSIM for cellular data.
- Protect the home line. Disable expensive data roaming on your regular carrier line.
- Save installation details. Screenshot instructions and support information.
- Download offline maps. Connectivity should never be your only navigation plan.
Also store your flight, transfer, lodge and fishing-package confirmations offline. If you are still preparing equipment, use our Costa Rica fly-fishing packing checklist before closing the suitcase.
When a Local Costa Rica SIM May Be Better
A travel eSIM wins on convenience, but it does not automatically win on price or local access.
A physical prepaid SIM from Claro, Kölbi or Liberty may make more sense when:
- Your phone does not support eSIM technology.
- You are staying in Costa Rica for an extended period.
- You need a local Costa Rican phone number.
- You expect to use a large amount of mobile data.
- You already know which carrier performs best where you are staying.
The trade-off is that you may need to locate a store, complete registration, handle a physical SIM and manage another number. For a short fishing vacation, many travellers will accept a slightly higher data cost in exchange for arriving with connectivity already installed.

Frequently Asked Questions
Stay Connected—Then Put the Phone Away
For my own Costa Rica travel, Roamless remains the service I know and use. I like being able to keep one eSIM installed, carry credits between destinations and contact support when the automatic connection needs help.
That does not mean every visitor needs the same setup. Airalo may make more sense if you want a familiar prepaid package. Saily may appeal to someone who values easy hotspot sharing and additional security features. GigSky provides another choice, especially if you want to test the connection before purchasing more data.
Whichever one you choose, prepare before leaving home. Install the eSIM, save offline maps, understand your data settings and keep the lodge contact information available without an internet connection.
Then, when you reach the river, put the phone somewhere safe. The connection you travelled all that way to find is not measured in signal bars.
