Destination lists change and regional plans differ from country plans, so check yours against GigSky’s own coverage page before you install anything.
Our verdict
A real trade rather than a trick: you get a week instead of a few days, and you hand over a card to get it. Worth taking if you are comparing networks over a longer run up to a trip, and worth skipping if you would rather not leave a card in an app you may never use again.
The catch: The card requirement is the trade for the longer window. Inflight and cruise plans are excluded from the trial.
