What is an eSIM?

An eSIM is essentially a SIM card that is embedded inside a device instead of a physical card that you insert into the phone. Instead of heading to a store and buying a plastic SIM, you just scan a QR code that your carrier or provider (such as eSIM Cards) issues you. That QR code downloads your plan directly into your phone.

So when people ask, “How do eSIMs work?”, the answer is simple:

• It’s built into your iPhone.
• No tray or plastic card needed.
• Plans can be added, switched, or removed anytime.

It’s flexible, secure, and honestly, the future of mobile connectivity.

Why use an eSIM instead of a SIM card?

Swapping SIM cards is annoying. You carry tiny cards, hunt for a pin tool, and if you’re travelling abroad, you waste time finding a local SIM shop. With eSIM setup, you can do everything online before you leave.

For example:

• Planning a holiday in Spain? Buy an international eSIM online before your flight.
• Heading for a business trip? You can compare SIM deals and just pick the best one for your needs.
• Students studying abroad? You can switch between your UK network number and an international data plan on the same phone.

And when people ask, “When to start an eSIM abroad?” – the answer is: anytime you want. You can activate it before your trip or the moment you land.
