“Best” depends heavily on your itinerary here — a week at a Sal resort and a three-island hopping trip through Fogo and Santo Antão have almost nothing in common when it comes to what you actually need.
Quick answer: For most visitors, an eSIM sized to the length of the trip is the best default, since it avoids the airport SIM-availability problem and works the same way whether you stay on one island or move between several.
Top Cape Verde eSIMs
For a single-resort beach holiday
If you’re not planning to leave the property much, resort WiFi combined with a smaller eSIM plan for excursion days covers most needs without over-buying data — the resort WiFi vs eSIM guide breaks down when each makes sense.
For island hopping
One eSIM works across every island in the archipelago, so there’s no need to reconfigure anything between stops — just adjusted expectations for each destination, as covered in the island hopping guide.
For a hiking-focused trip
Santo Antão and Fogo’s trails see minimal to no coverage regardless of which connectivity method you choose, so the “best” setup here is really about having a reliable connection in town before and after, not during the hike itself — see the Santo Antão guide.
For business or work trips
Travelers needing dependable connectivity for calls or uploads should prioritize coverage reliability over cost, sticking to islands with the strongest infrastructure — Santiago and Sal in particular.
Why a physical SIM rarely wins this comparison
Beyond the airport-availability issue, a physical SIM also means losing your home number for calls and messages during the trip, something an eSIM avoids entirely — the local SIM vs eSIM guide covers this trade-off in more depth.
FAQ
Is there one single best option for everyone?
No — it depends on whether your trip is resort-based, multi-island, or hiking-focused.
What’s best for a resort-only stay?
Resort WiFi paired with a smaller eSIM plan for days off the property.
What’s best for island hopping?
A single eSIM covering the whole trip, since it works archipelago-wide.
Does connectivity method matter for hiking trips?
Less than you’d think — trail coverage is minimal regardless of setup.
Why not just buy a local SIM?
You lose your home number for the trip, and availability at the airport is limited.
Should business travelers prioritize cost or reliability?
Reliability — sticking to islands with the strongest infrastructure matters more than saving a few euros.
Final Recommendation
Match your connectivity choice to your itinerary type rather than defaulting to one option. See the how much data guide to size an eSIM plan once you’ve picked your approach.
