Hi! We don’t have such cards in Greece, so I can’t help.

But we had discounts when we showed a disability paper.

Hi! I also used the pocket wifi option, which AJ suggested. It’s not free but it’s portable, you have it anywhere and anytime you want and can also connect many people (we were 7), so it’s totally value for money. This is the one we used.

Free wifi we used only in the hotel I think.
