What is an eSIM and how does it work?

An eSIM, or embedded SIM, functions like a traditional SIM card – minus the physical component. Instead of being a separate external piece, it's built directly into your device's internal framework, making external slots redundant. Much like standard SIM cards, eSIMs ensure a seamless connection between your device and service provider, so you can call and browse with consistent connectivity.

Currently, not every device supports eSIM technology. Many device manufacturers are on track to phase out the physical SIM card slot in the coming years. For instance, Apple's iPhone 14 in the US has fully adopted eSIM technology, although it retains the SIM card slot in Australia. Motorola Razr has also shifted entirely to eSIM.

Presently, many individuals utilize eSIMs as a second SIM. This enables them to have an alternate plan from a different carrier that may be better suited for specific job roles or travelling.

Advantages of using an eSIM

An eSIM might not sound that revolutionary until you start to think about the benefits. Here are four common eSIM benefits that can seriously improve your mobile phone experience.

• Multiple Network Options: Love your current call package but need a better internet deal? With eSIM, you don’t have to compromise. Tap into different providers for various needs without the hassle of physical SIMs.

• Durability: eSIMs are immune to wear and tear, reducing the risk of damage due to water, dust, or mishandling.

• Eco-friendly: Reduce plastic waste and the environmental footprint with eSIMs, offering an eco-conscious choice.

• Broad Compatibility: Leading phone manufacturers, from Apple to Google, support eSIMs. Simply scan, activate, and you're set!

Everything about an eSIM is done remotely. Connecting to a mobile plan usually means you can upgrade to a better telco like Circles.Life with just a few taps on your phone, without having to swap confusing, lookalike SIM cards.

Drawbacks of using an eSIM

For most people, there are very few disadvantages to using eSIMs. But there are a few niche situations where eSIMs are more restrictive than traditional ones.

1. Switching between phones

With a traditional SIM, switching between handsets is straightforward: simply remove the SIM and insert it into the new phone. However, with an eSIM, you must contact your service provider to make the switch.

In the early days of SIM cards, these small pieces of plastic store all your contact details. Today, most users store this information in the cloud. So, unless you're accustomed to using an older non-smartphone, the transition shouldn't pose a problem.

2. Rules out old tech

Once you transition to an eSIM, you’ll lose compatibility with older devices. If you've still got a Nokia 3210 hanging around that you like to use from time to time, it won't work with your current number anymore.
