SIM cards (Subscriber Identity Module) that we all know for containing our phone number, contacts and other mobile line-specific data have changed a lot in recent years.
Before we had standard size SIM cards, then microSIMs were introduced, then nanoSIMs. Thus we arrive at eSIM (embedded SIM), a modern version of SIM cards that, beyond aesthetic differences, provides technological innovation.
What is an eSIM?
An eSIM is simply a digital SIM card integrated into the mobile device. But, the fact that it does not have a physical format does not prevent it from providing some advantages and conveniences of use. Quite the opposite.
What are the advantages of eSIMs?
Activating an eSIM card is easier, as it involves downloading a user profile represented by a QR code from the operator. This feature makes it easier to change operators, since you do not have to change the SIM card to do so.
It also allows you to have more than one number working on the same phone (although only one actively) and they can be transferred between nearby devices. It takes up less space and since it is integrated with the device’s hardware, it performs better overall.
On the other hand, it adapts more easily to devices other than a smartphone such as smart watches, headphones and devices designed for the Internet of Things.
How to check if your phone supports eSIM technology?
iPhone models compatible with eSIM technology
iPhones from model XS onwards support eSIM. And you can check it as follows:
Go to Settings > Cellular network and verify that the Add eSIM option is present.
Android models compatible with eSIM
Most recently manufactured Android phones are compatible with eSIM. For example, the Samsung Galaxy series starting from the S20 model, Xiaomi 12T Pro phones, Huawei Mate 40 Pro, Huawei P40 Pro, Google Pixel 6 onwards.
In these Samsung phones, eSIM activation is done from Settings > Connections > SIM Manager.
On Huawei phones, from Settings > Mobile networks > SIM management.
