GigSky or Airalo: which is better?
GigSky
Best for cruise passengers and multi-country travellers who want a long-running brand with flexible plan lengths.
Ahead of Airalo on
Exact 3, 7 and 14-day plans
Before you buy

The plan starts on any covered network and cannot be paused — easy to start early on a cruise.
Some reviewers report slow or patchy coverage in places.
Refunds

Airalo
Best for travellers who know roughly how much data they need and want the cheapest small pack, from the biggest catalogue.
Before you buy
No refund once the eSIM is activated, and refunds can come back as store credit.
Reviewers often mention fiddly installs and manual APN settings.
Some reviewers report connections dropping outside major cities.
Refunds
14 days to withdraw, ending once the eSIM is activated. Replacement or refund if an activated eSIM fails through Airalo’s error and cannot be fixed within 10 days; refunds may be paid as Airmoney credit.
Or skip the trade-off: SimbaSIM
