Why eSIM is Better

 

eSIM, also known as embedded UICC (a hardware component that stores operator profiles), is the next-generation of SIM cards. Unlike traditional SIMs, it doesn’t need a physical card slot so it can be integrated into modern wearable devices.

eSIM is also better for the environment, as it requires fewer plastic pieces to be produced. This reduces greenhouse gas emissions and the use of chemicals during factory production.

1. Itג€™s more secure

Though eSIM provides some advantages, it does not entirely replace physical SIM cards. Nonetheless, this is an important step in the right direction.

Embedded SIM (eSIM) technology is an evolution of the traditional SIM card and now a standard feature in many phones and mobile devices. Unlike traditional SIMs, eSIMs are inextricably linked to your device’s motherboard, making it impossible for cybercriminals to duplicate them and insert them into your device.

eSIMs are not only safer, but they also eliminate the need for physical SIM card exchanges and offer users a simple way to connect their devices to cellular networks. Network providers save both time and money by managing eSIM profiles remotely instead of sending personnel into the field.

The primary security advantage of eSIM is its reduced vulnerability to SIM-swapping attacks, where a fraudster pretending to be you contacts your carrier to activate your number on their SIM. These types of scams typically aim to steal personal information like bank account details or social media credentials.

2. Itג€™s more convenient

Traditionally, when replacing your mobile phone or tablet, the plastic SIM card must be removed. On the other hand, an eSIM is designed to remain permanently in your pocket or purse and serves two purposes: it’s a functional mobile device and convenient way to pay your monthly bill and access favourite apps while on-the-go. With an eSIM in tow, making your monthly bill look even better is now even simpler; it offers many of the same features as your smartphone and takes only minutes to activate and sync.

3. Itג€™s more flexible

For instance, switching to a different carrier in another country with an eSIM is effortless. This is possible as the entire process of changing operators and signing up for cellular services abroad with an eSIM is automated through software programs.

This makes it impossible for cybercriminals to commit port-out fraud, in which someone uses your phone number to make calls and send texts using their own device. Furthermore, SIM-swapping attacks – where someone pretending to be you attempts to change your number to their own – are also prevented.

The flexibility of eSIM is ideal for fleets that need to maintain connectivity wherever their vehicles may go. It enables them to connect directly to local networks, making things simpler for operations teams. Zero-Touch Provisioning also eliminates manual configuration, saving time and energy in various industries such as large industrial IoT deployments in power plants or factories as well as shipping operations.

4. Itג€™s more environmentally friendly

Embedded SIMs are a more environmentally friendly alternative than physical SIM cards, since they require less air travel and use fewer raw materials during production. Furthermore, embedded SIMs can save users money in the long run due to their ability to switch networks and remain connected even while traveling.

In the future, eSIMs will become increasingly common on smartphones and other devices with cellular connectivity. This marks a major advancement in reducing mobile device carbon footprints and wireless services’ overall sustainability – particularly for wearables where smaller device dimensions can significantly impact battery life and performance. Furthermore, this technology will enable manufacturers to design phones with more features while using less physical space; smartwatches for instance could store more data and offer more features than phones that don’t feature a removable SIM card tray.
