What happens if my eSIMFlyer data runs low mid-trip?

Updated April 22, 2026

No need to panic or hunt for unreliable airport Wi-Fi! If your data starts to dwindle while you're navigating London or exploring Lisbon, topping up is a breeze. Simply head over to the 'My eSIMs' section on the eSIMFlyer website. You can purchase additional data for your active eSIM plan quickly and efficiently, ensuring you stay connected without interruption. We recommend keeping an eye on your usage and topping up before you hit empty, especially before a long flight or a crucial transit.
