How does a London eSIM work?

An eSIM is an embedded SIM card, and you probably already have an eSIM-compatible device. When you install an eSIM for a country or region, it lets your device connect to local networks in that area. This means your device will have data without needing Wi-Fi or paying roaming charges.

How much travel data do I need in London?

How much data you require for your vacation to London depends on a few factors.

Think about the places you’ll explore where you won’t have an easy Wi-Fi connection. Will you need an internet connection to access maps, directions, and ticket-purchasing sites?

With a London eSIM, you’ll always have immediate access to data wherever you are, whenever you need it. Not sure how much you’ll need? No problem! You can start with a basic data plan and easily add more data if needed.

Will I pay roaming charges with a London eSIM?

Not a penny (or pence) on roaming charges! Save your money and spend it on freshly-baked scones instead. Mmmm.

A London eSIM will instantly link your mobile device to a local network in London, allowing you to access prepaid data while traveling.

But do us a favour. Check that you have turned off Data Roaming on your primary SIM. Using an eSIM for your London trip can help you save money, and allow you to fully enjoy every moment without the worry of overspending on data.
