What are eSIM for Phones and How They Work

In smartphones space is increasingly important, and to make room for new components soon we will have to salute the classic SIM and embrace the eSIM.

Within the smartphones of the future space will be everything. The search for more housing for batteries, screens and sensors will do, by force of things, the victims. For this reason Apple decided to sacrifice the headphone jack from 3.5 mm, but soon also the SIM could be replaced with the eSIM.

Today’s phones have the latest features, so you won’t be afraid to compare with some computers. To make them so efficient, however, in time designers and designers had to “cut” some components. Especially to make room for batteries that can withstand more and more specialized and powerful applications. According to many experts soon even the classic Sims will be replaced to prevent their slots occupy too much space. In its place we will see the eSIM also called SoftSIM. In practice a microchip printed on the logic board of the smartphone, or on any other electronic device with connectivity to the cellular network.

What are the eSIM

In practice instead of the classic coupon, that in time if you notice it has become smaller, we will have a microscopic device capable of containing all the data so far stored inside the circuits of the classic plastic card. To put it all the eSIM are not a real novelty. Similar devices are already in use on smartphones and tablets, only they do not cover the function of replacing a SIM but are used to save data useful to use the phone. No problem with regard to the Code ICCID, that is the one that uniquely identifies the SIM and is used during the transition from one operator to another, this can also be inserted in the SoftSIM, or ith what to say.

Advantages of eSIM

In addition to the obvious recovery of space that will be used by developers and manufacturers to achieve new functions, it is clear that the eSIM bring advantages to users as well. The consumer in fact with this system shorten the necessary time in the change of operator, as it will no longer have to replace the physical card in plastic. A call to customer service will be enough to move your data to the new user. In this way you will also avoid losing the phone numbers saved on the SIM and not transferred before the operator change. Not to mention the problems when you change your smartphone. Often the old phone card is not compatible with the new (depending on size, normal, Micro or Nano). And you have to go to our operator to request a new one. Operation that over time also costs money. With the eSIM these steps will be canceled.

How to register a virtual SIM

At the moment the real issue of the eSIM is that manufacturers do not have a unique standard for use. This means that at the moment creating your own virtual card could be more complicated than using a classic SIM. Apple is one of the few companies that has presented a clear plan about it for users. To register an eSIM just go to settings and then enter the cell phone section. At this point we have to wait a few moments and will appear an information sheet where we can select one of the telephone operators available in the area where we are. You will be able to choose between the various rates and promotions available at that time and thus subscribe to the contract with the operator you prefer. At the moment this solution is only possible on iOS. Given the importance of the topic but it is not to be excluded that soon also many other manufacturers will explain their plans on virtual Sims.
