eSIM - what is it and how does it work?

What is the mysterious sounding eSIM and how it can make your phone easier to use?

What is eSIM?

eSIM is the successor of traditional SIM cards inserted into the phone. Its use is the next stage of miniaturization, because its dimensions are even smaller than a Nano-SIM card. eSIM is a chip, or more precisely an MFF2 chip, the dimensions of which are 6 x 5 mm. By introducing this standard to phones, individual models can become more slender. eSIM is not a plastic card. Instead, it is its virtual counterpart, which is saved on the already indicated chip.

eSIM, like its traditional counterpart, allows you to log into the cellular network to make a call or use the Internet. The card is activated by scanning the QR code. For now, however, this solution can only be found in high-end devices: Apple and Samsung smartphones, as well as some smartwatches and other products.

Advantages of eSIM:

What are the advantages of the eSIM solution? First of all, it can be installed on several devices at the same time. One phone number is then used, regardless of whether it is a smartphone, watch or tablet. There are also security reasons for using it. First of all, such a phone is much easier to track in the event of theft. First of all, uninstalling the electronic SIM card requires the knowledge of the PIN code. It is also a convenient option for people who travel a lot. You can activate the local offer of the mobile operator from the phone level, without the need to obtain a physical SIM card.

So far, the only Polish operator that has allowed its customers to use the eSIM card is Orange. Of course, apart from the telephone network itself, you also need to take into account whether the device supports the electronic SIM card at all. This solution will be more and more common in models launched on the market.
