Why eSIM is a Trendsetter: SIM vs. eSIM

Smartphone manufacturers are increasingly embracing eSIM technology, making it a mainstream feature. Apple’s iPhone 15 models in the US have already shifted to eSIM-only, eliminating the need for physical SIM cards. While Android manufacturers are taking a more cautious approach, many are also adopting eSIM technology. But what benefits do consumers gain from using an eSIM smartphone? In this article, we explore the advantages of eSIM technology.

What Is an eSIM?

An eSIM, or embedded SIM (Subscriber Identification Module), is a chip integrated into your smartphone’s motherboard. Unlike physical SIM cards that can be swapped out, eSIMs are permanent and can only be changed by contacting your carrier, scanning a QR code, or adjusting settings.

Advantages of Using an eSIM

1. Easier Carrier Switching

Quickly switching carriers is a significant advantage of eSIM-compatible devices. The information on an eSIM can be rewritten, allowing for seamless transitions between carriers without the need for physical SIM cards. This eliminates the wait time for new SIM cards or the hassle of swapping them.

Moreover, over 400 carriers in 190 countries and regions support eSIM, making it ideal for international travelers looking to switch to local carriers without incurring hefty roaming charges.

2. Multiple eSIM Storage

eSIM devices, like the iPhone 14, can store up to eight eSIM profiles, with two active simultaneously. This flexibility allows users to own and store multiple mobile numbers. This feature is particularly beneficial in areas with varying carrier coverage, as you can easily switch to a carrier with better reception.

It also enables users to take advantage of different plans from various carriers. For example, you can choose one carrier for voice plans and another for data while keeping your old number without the need for porting.

3. Enhanced Dust and Waterproof Rating

eSIM-only smartphones have fewer ports, reducing vulnerability to dust and moisture. This design choice can contribute to improved device durability and fewer breakdowns. The absence of a physical SIM card slot means fewer openings for potential damage.

4. Space Efficiency

eSIMs are significantly smaller than nano SIM cards, occupying less physical space on smartphones. This space-saving feature allows manufacturers more flexibility in designing their devices. Manufacturers can allocate the freed space for additional components like chips, sensors, or larger batteries, potentially resulting in improved device performance.

5. Enhanced Device Tracking

Since eSIMs are not removable like physical SIM cards, it becomes more challenging for thieves to dispose of the SIM if they steal your device. This added layer of protection can facilitate the tracking of lost or stolen smartphones, enhancing security.

6. Smartphones That Use eSIM

Several smartphones support eSIM technology:

  • Apple: iPhone 14 models in the US, as well as other iPhone models like the SE (2020 and 2022), 11, XS, XR, 12, and 13 Series.
  • Google: All Pixel devices from Pixel 2 to Pixel 7 Pro.
  • Samsung: Galaxy S20, S21, and S22 series, Flip and Fold series, and Note 20 series.
  • Oppo: Find X3, X3 Pro, X5, and X5 Pro.
  • Sony: Xperia 1 IV, Xperia 5 IV, Xperia 10 III Lite, and Xperia 10 IV.

Evolution from SIM to eSIM

The Pros of eSIMs

eSIMs come with their own set of advantages:

  • They are convenient and can be downloaded wherever you have a network connection.

The Cons of eSIMs

However, there are some downsides to eSIMs:

  • They are not available for older phone models due to their relative novelty.
  • Transferring data from a damaged phone requires downloading from the cloud, which can be inconvenient.
