You don’t need a promo code; just look at the bottom of the app and tap the “Visa Benefits” button. Tap the “Check Eligibility” button at the center of the screen and enter your card number. The app then tells you which plan you’re eligible for, and you can choose to redeem it.
From there, GigSky will walk you through adding your free eSIM to your device and using it in place of your U.S. carrier’s data. Once you add the GigSky eSIM to your device, you can reload it and add data packages as you travel, even after you’ve used up your free Visa data.
Next time you're heading abroad, check your wallet before you do anything else — you may already have free data waiting for you.
