What is a UK eSIM (And Why You Need One)

A UK eSIM is a digital SIM card that lets you get mobile data in the UK without inserting a physical SIM.

• No roaming charges


• No waiting for delivery


• Works in minutes

But not all eSIM plans are good. Some throttle your speed. Some block hotspotting. Some say "unlimited" but don’t really mean it.
