Discovering eSim and how it operates

1. What is eSIM?

eSIM, also known as embedded SIM, is an electronic SIM that eliminates the need for SIM trays or physical SIM cards like traditional ones.

eSIM requires support and activation from networks and carriers. However, not all networks and carriers support eSIM. Additionally, on devices like iPhone XR, XS, and XS Max, as well as Pixel, eSIM is used to support a secondary SIM.

Essentially, eSIM is a small chip inside the phone, functioning similarly to how NFC chips are used in payment technologies like Apple Pay and Google Pay.

Information on eSIM can be reprogrammed, meaning users can change carriers through a simple phone call. Furthermore, using mobile data on eSIM devices is also much simpler.

Finally, the GSMA Association has recognized the eSIM standard worldwide.

2. When is eSIM available?

eSIM is currently available and accessible with some network providers. Users of iPhone XS and XS Max devices must use the network provider's app or QR code to scan.

In the UK, network providers EE and Vodafone have supported eSIM. However, Vodafone currently only supports it for Apple Watch Series 3 or 4 Cellular.

Truphone, a global mobile network, has stepped ahead of traditional carriers by offering eSIM data packages. Users can purchase these data packages through the MyTruphone app. Truphone's international mobile data packages operate in over 80 countries, including countries in Europe, the Americas, and Australia.

3. Advantages of eSIM for phone manufacturers

Due to its extremely small size and lack of need for physical SIM cards or SIM trays like traditional ones, phone manufacturers can leverage this to integrate additional components.

4. How does eSIM work?

As per EE, if a user has both a physical SIM and an eSIM connected to two different networks, the iPhone will display both networks simultaneously on the screen.

When the phone is in standby mode and both the SIM and eSIM are provided, users can make calls and send messages on both numbers.

Furthermore, if desired, you can choose the second SIM to use mobile data, which is extremely useful when living abroad and using local eSIM data.

Not to mention, you can store multiple eSIMs on an iPhone, but only one eSIM can be used at a time.

To switch to eSIM, tap on Settings => Cellular => Cellular Plans and select the data plan you want to use.

5. eSIM Trends on Smartphones

It's highly likely that future smartphones will utilize eSIMs instead of physical SIM cards (and SIM slots) as seen today. The first devices to ditch traditional SIMs might be introduced as early as 2020. There are plenty of reasons to believe it's too soon for Apple to adopt eSIMs for the iPhone XI this year.

Aside from the Apple Watch Series 3, Apple's latest iPhone models, including the iPhone XS and XS Max, now incorporate eSIM technology. Additionally, Apple's iOS 12.1 update supports and activates eSIM.

Besides, Google's Pixel 2 also supports eSIM, although support is currently limited to usage in the United States for Google's Project Fi. Network providers will roll out support shortly after eSIM's launch.
