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.

FAQs about eSIM in London

Check your device

Most newer phones, tablets, and computers are already eSIM-compatible, so use our eSIM device checker to make sure you have a device that can accept an eSIM data plan.

Free Wi-Fi is great when it’s available and working well, but some destinations make it just about impossible to get a good connection. Having data as a backup ensures you remain connected regardless of Wi-Fi availability.

We’re proud to provide aloSIM customers with fast eSIM data connections that allow them to talk, text, surf, and stream comfortably. You’ll likely experience a 4G (sometimes 5G) or LTE equivalent network in most locations, depending on what’s available in the area.
