For years, the SIM card has been used in their different formats to connect mobiles to mobile voice and data networks, but now iSIMs and eSIMs are making their way and could be how you connect your mobile in the future.
[El siguiente paso en tarjetas SIM va a hacer que no ocupen nada de espacio en tu móvil]
Companies like Google are already making these technologies more relevant, and manufacturers are finding it easier and easier to integrate them into their smartphones, so we’ll see them more often.
Next, we will explain how each of these technologies works with which your mobile can connect to the mobile networks of telemarketers.
SIM, the card of a lifetime
Advantages and disadvantages of a Dual SIM mobile
The SIM card is the small card with a zip that is inserted in the mobile for this subject to the Internet and data connection after having contracted it with the operator.
It is physical and fits in to the SIM tray of all mobile phones, although there are three sizes depending on the space they take up.
There is the classic SIM card, the slightly smaller Micro SIM and the Nano SIM which takes up almost only the size of the chip, each of these types of SIM allowing the manufacturer to better take advantage of the internal space of the device. ‘device.
For example
The eSIM removes the need for this physical card and directly integrates a communication chip, which is the one that must connect to the teleoperator networks to give you a data and voice connection.
This makes porting easier than with a traditional SIM, since you will not have to wait for the physical card to be sent to you, but you will only have to give the ICCID code of your mobile to your new operator to approaches.
Although it occupies a significantly smaller footprint, it also requires a separate processor chip to house this technology.
It still has some drawbacks, such as difficulties when changing mobile and migrating the number to another device, although Google has announced that it is working to integrate it into Android as a native option.

The iSIM, presented in 2022 by Vodafone and Qualcomm, changes slightly compared to the eSIM, since in this case it is the processor that would integrate everything related to communications, thus eliminating the need to have a different chip for the eSIM.
As you can see, the advantages include the fact that the space occupied by the SIM or eSIM is saved, which would also facilitate the integration of communications in devices with the Internet of Things.
The way to carry out the probability would be the same as with the eSIM, managing everything with the operator and giving them the identity number of your phone to carry out the process.
The extra space gained with this method can be used by the manufacturer for something else, and also allows processors to have more capabilities and manufacturers to spend less on components in manufacturing processes.
