Best for cruise passengers and multi-country travellers who want a long-running brand with flexible plan lengths.
Ahead of Holafly on
Add days to the same eSIM
Before you buy
The terms rule out refunds for unused plans; newer requests are case by case.
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

Holafly
Best for travellers who want unlimited data at one simple price and can buy the exact number of days up front.
Ahead of GigSky on
Every plan is unlimited data
Before you buy
No top-ups or extensions — a longer trip means buying and installing a second eSIM.
One price for every country, so destinations that cost less elsewhere — Thailand, the US — cost the same here.
Refunds for connection problems are only considered if you report them during the trip.
Refunds
Full refund within 6 months if the eSIM was never activated. After activation, case by case; connection problems must be reported before or during the trip, and a $3.50 fee can apply.
