Virtual SIM cards, also known as eSIM , is a technology that is booming. This is mainly due to the evolution of smaller portable devices, such as smart watches. In these devices a saving of space can suppose a big difference in weight and dimensions . Until now we have been using the classic SIM cards, that is, those small pieces of plastic with an integrated chip. These SIMs are provided by our operator and are those that allow us to have a connection to the mobile data and telephony network.
These plastic cards also suffered size reductions throughout history. First we had the standard SIM cards, then they were reduced in size and they were called microSIM . Finally it was reduced again to be called nanoSIM . Now, with the eSIM it is a matter of completely dispensing with the plastic , redicing its size to zero.
What is a virtual SIM or eSIM card?
To understand that it is an eSIM we have to stop seeing it as something physical, since the eSIM are data . It is a technology that replaces traditional plastic SIM cards, integrating their operation in the mobile device.
The eSIM data is stored on a specific chip within the hardware of the device. This information is stored in this dedicated chip to ensure its isolation and prevent malicious applications from accessing this information.
The functionality of a traditional SIM and an eSIM is exactly the same , only that the latter are already integrated into the system. In general, devices with eSIM are already preconfigured from the operator, especially in smart watches.
If I use eSIM can I change operator?
Many users wonder what is the procedure to change operator with eSIM, since coming configured from the operator gives rise to think that it can not be changed. This is incorrect, in fact the eSIM is a technology with great advantages .
Virtual SIM cards allow us to change operator instantly , because we will not have to wait for a plastic SIM to arrive. In general, it is enough to scan a QR code provided by the operator and we will have the eSIM configured.
In other words, with the arrival of the eSIM, the portabilities will continue to exist and will be made even faster . This technology also allows you to use the eSIM on different devices without having to remove and put a physical card. Simply activate the eSIM on the desired device and you're done.
What do I need to be able to use an eSIM on my phone?
In order to use the eSIM you need a compatible phone , that is, to bring the dedicated chip for use. In addition, you will have to make sure that your operator can offer you compatibility with the eSIM , since at the moment in Spain not all offer this possibility.
At the moment there are not many compatible terminals with this technology in the market, but everything points to 2020 being the trend. A terminal with support for eSIM are the Google Pixel 2XL. Operators in Spain that allow the use of eSIM are Orange and Movistar for the time being.
Advantages of the eSIM.
The use of eSIM cards has many advantages:
- Friendly with the environment , since it does not need plastic.
- It does not suffer wear or deterioration due to its use.
- It improves the security , since in case of theft they will not be able to extract the SIM.
- It means saving space in the devices by not having to reserve a space.
