What is Unlimited eSIM in the UK?

Unlimited eSIM in the UK refers to a digital SIM plan that offers high-volume or truly unlimited mobile data access across the country. Unlike traditional SIM cards, which require physical installation, an eSIM is embedded directly into a compatible device.

How eSIM Technology Works
