What is a SIM?

A SIM (Subscriber Identity Module) card is a secure, compact, mobile memory chip designed to store essential information about a mobile service and associate it with a specific device.

What is an eSIM?

An eSIM is simply a SIM card that’s embedded into a device. The information stored by the eSIM is downloaded onto the eSIM.

Are they as secure as standard SIMs?

Yes – they can only be used once and unlike a traditional plastic SIM, someone can’t remove the sim card if your phone is lost or stolen.

Can my phone have multiple eSIMs?

You can store multiple eSIMs on the same phone. This means you can easily switch between different mobile carriers or plans without the need to physically swap SIM cards. It also means you can switch between mobile numbers.

Can you have a SIM and an eSIM?

Certain phones come equipped with both an eSIM and a traditional plastic SIM card slot, which are called “Dual SIM with eSIM” phones.

Which phones support eSIMs?

Since the introduction of the iPhone Xs, all subsequent iPhone models have been equipped with eSIM support. Additionally, a growing number of Android phones are now offering compatibility with eSIM technology.

What is an eSIM QR code?

QR codes are a special type of barcode designed to allow effortless access to information using a smartphone. These codes require scanning with your phone’s camera. Your phone comes equipped with a built-in QR code reader, which automatically activates during eSIM setup, eliminating the need to download any external applications.

I can’t get my eSIM to work… what should I check?

If you can’t get the eSIM to work, please check:

  • Has the eSIM been used on a different device? If so, it will not work.

  • Is your device able to support eSIMs? See the FAQ above or use Google to find out if it’s compatible.

  • Check you are running the latest version of your phone’s operating system.

Is there any difference in network coverage or quality between eSIMs and physical SIMs?

No, eSIMs offer the same network coverage and quality as physical SIMs, as they connect to the same mobile networks.

What are the benefits of using eSIMs?

eSIMs offer the convenience of remotely activating and managing your mobile service, enabling easier switching between carriers or plans without needing a physical SIM card.
