However, a mobile device could not perform its basic functions without a SIM card and it would be unreasonable to think of using a cellphone without it. Despite this, there are cell phones that work without the need to insert an active SIM.

The iPhone XS and XS Max surprised everyone with its innovative technology with one card Virtual SIM integrated . This is surprising, since it could be the north of all cell phones in the future, leaving aside the usual physical SIMs that can be damaged or lost.

Ma what are virtual SIMs or eSIMs really and how do they work? Is it worth making the generational change? In the following article we will explain what they are, how they work and the advantages that these new virtual cards can offer that seem to be here to stay.

What is an eSIM or a virtual SIM?

The traditional SIM is a card offered by telephone companies that allows the phone to make calls or have a data plan that allows you to surf the Internet. Over time this card has undergone several changes, greatly reducing its size, but now it will no longer be necessary to use physical SIMs.

Now the premise of SIM cards has changed, giving way to the new eSIM or commonly known as a virtual SIM card. This type of technology excludes the use of physical cards via chips that are virtually integrated into the device, doubling performance and data that a common SIM could host. These virtual SIMs are activated remotely by purchasing a mobile device compatible with the technology.

How does eSIM work?

While it may seem a little difficult to understand at first, the operation is simple. Just buy the phone and contact the telephone operator of your choice in so that it can remotely activate the virtual chip.

Once the eSIM is activated we will be able to enjoy our equipment with its data plan included and there will also be there compatibility to connect multiple devices to the eSIM. And although the idea is a bit young and few companies have tried their hand at this technology, it is possible that in the future eSIM cards will be the most common due to their practical use.

Advantages of the eSIM

Undoubtedly, the best advantage of this technology is that it offers more freedom for users, since it allows them to choose the phone company they want and not only ties them to the one that has mobile compatibility.

As this is a virtual chip, there is a possibility that other equipment such as smartwatch or tablet will include the function of connecting to the eSIM network sharing data, without the need to have different traditional SIMs or to change the SIM from one device to another. another.

Another big plus is when you buy a mobile you will not have to buy a SIM, as in theory it will include one or, if so, you will be able to communicate directly with the company of your choice and quickly activate a virtual chip.

Disadvantages of eSIM

The main drawback is not the board itself, but the equipment as such. As this technology starts to become popular, new phones will need to have a new design that does not include the SIM slot.

If indeed this type of sim manages to supplant the previous one, making only the devices work with this technology, will lead to the disposal of many of the devices that today have millions of users, forcing them to buy a new phone with eSIM technology.

Teams and companies that use eSIM cards

As this is a very new technology on the market, few companies have developed support for eSIM and despite iPhone XS and XS Max surprised everyone with this technology, there were already models from other companies that worked with eSIM such as Google Pixel 2. For its part, in Spain the Orange company is already using equipment with this technology.
