Revolut

Revolut, known as a fintech app, layered eSIM data plans on top of its core money-transfer service. Plans start at £1.50 for over 100 destinations, and you can activate up to 15 eSIMs at once (useful for family trips or frequent re-registration). Revolut Premium members get additional data top-up credits.

This suits Revolut users who already rely on the app for currency exchange and payments abroad, consolidating travel tools in one place. For those without a Revolut account, the account creation hurdle and fintech-first focus may feel unnecessary if all you need is data, though the integration with currency conversion does add value for multi-country trips.
