- 6 min reading time
Updated September 2026. Calico Link and Holafly both offer prepaid travel eSIMs, but they serve somewhat different travel needs.

If you are choosing between Calico Link and Holafly, start with one question: do you want unlimited data, or would a smaller fixed-data plan be enough for your trip?

What is Calico Link?
Calico Link is a travel eSIM store offering prepaid connectivity for destinations around the world. Its catalog includes fixed-data plans for travelers who know approximately how much data they need, selected unlimited-data eSIMs, multi-country plans and selected products that include calls and SMS.

What is Holafly?
Holafly is an international travel eSIM provider whose main destination products emphasize unlimited mobile data. It offers eSIMs for more than 200 destinations, lets travelers choose plan duration for many products, and provides a mobile app for purchase and management.
Holafly also offers regional and global products. Hotspot allowances and voice/SMS features vary depending on the product, and some unlimited plans may be subject to fair-use policies applied by local networks.
1. Unlimited data
This is Holafly’s strongest point of differentiation. Many Holafly destination eSIMs are built around unlimited data, which can be attractive to travelers who stream video, work remotely, upload large files or simply do not want to monitor their data balance.
Calico Link also offers unlimited-data eSIMs for selected destinations, but it combines those with fixed-data products. That can be useful when unlimited data would be more than you need.
Best choice: Holafly can be a strong fit if unlimited data is your top priority. Calico Link can be a better fit when you want to compare unlimited service against lower-capacity fixed-data options for the same style of trip.
2. Fixed-data flexibility
Not every traveler needs unlimited data. For a short city break, a few gigabytes may be enough for Google Maps, messaging, ride-hailing and occasional browsing.
Calico Link offers many plans with fixed data allowances such as 1GB, 3GB, 5GB, 10GB or higher depending on the destination. This allows travelers to buy around their expected usage instead of automatically choosing an unlimited plan.
Holafly’s standard travel positioning is much more focused on unlimited-data plans, so travelers who prefer small fixed allowances should compare carefully.
3. Calls and SMS
Many Holafly destination eSIMs are designed primarily for mobile data. Travelers can continue using internet-based calling apps such as WhatsApp, FaceTime or Messenger. Holafly also offers subscription products with separate phone-number and messaging features, but these are different from traditional local calling plans.
Calico Link offers selected destination eSIMs with mobile data, voice minutes, SMS and a phone number. This can be useful if you need traditional calling for hotels, restaurants, local contacts or services that expect a phone number.
4. Hotspot and data sharing
Hotspot rules are important for travelers carrying a laptop, tablet or second phone. Calico Link supports hotspot on selected products, including some data-only plans, but the exact feature should be checked before purchase.
Holafly supports data sharing on many plans, but hotspot usage can have a separate allowance even when the eSIM itself is marketed as unlimited. The exact sharing limit can vary by destination and product.
5. Trip length
Holafly is convenient for travelers who think in days rather than gigabytes. Many of its unlimited products allow the traveler to choose a trip length and buy coverage for that period.
Calico Link plan validity varies by product. This can work well when you are choosing around a specific data allowance or a defined travel route rather than an exact number of unlimited-data days.
6. Regional and multi-country travel
Both providers offer options for travelers visiting more than one country. Holafly has regional and global unlimited-data products, while Calico Link offers regional travel eSIMs that cover multiple destinations with one eSIM.
For any regional plan, check the full country list before purchasing. “Europe,” “Asia,” or “North America” coverage can differ between providers.
Which one should you choose?
Choose Calico Link if:
- You want the option to buy a smaller fixed-data package instead of unlimited data.
- You want to compare fixed-data, selected unlimited, and selected calls + SMS plans.
- You need a regional eSIM or a selected plan with traditional voice and SMS features.
Choose Holafly if:
- Your main priority is unlimited mobile data.
- You prefer selecting your plan around the number of travel days.
- You expect heavy data use and do not want to track a fixed GB allowance.
Calico Link vs Holafly: final verdict
Holafly is a strong choice for travelers who want a simple unlimited-data proposition. Calico Link is a strong alternative for travelers who want more control over how much data they buy, while still having access to selected unlimited and voice/SMS options.
Neither provider is automatically best for every trip. Compare the destination, included countries, validity, hotspot rules, network availability and whether the plan includes only data or also traditional voice and SMS.
