Telefónica announced the arrival of eSIM to the European market. It is about the implementation of the sophisticated system of an eSIM in Germany with the Samsung Gear S2 Classic 3G model, but people wonder what is this all about?

This technology is based on an electronic SIM card that does not require the insertion of a physical card in mobile phones, tablets, laptops or any other mobile device with connectivity to telephone networks.

It is important to point out that under this system the SIM will not disappear, it only reduces its size to the smallest expression and is integrated as a very minimal component next to the modem of the device that will use it, in this way it only needs to receive basic programming .

A line eSIM You can hire it for any device that can be connected and that comes with the appropriate technology, from a washing machine, the car, a refrigerator or an electronic assistant. In the future, it will be very easy to configure your eSIM, it will be enough with a basic instructions from the operator and an app for it to work correctly.

The effort will now be made by manufacturers, as they must develop new production and assembly lines for mobiles, devices and household appliances that incorporate this microchip.

In the case of equipment without a screen, they must be sold with the eSIM contract from its origin, since it would not be practical for the user to carry out this somewhat complex process.

Pedro Gil, from Telef√≥nica’s Global Terminal Unit, pointed out that beyond the benefits and versatility provided by this new technology, operators must comply with the same obligations in terms of regulation and security with both the eSIM and the physical card of nowadays.

“Among the aspects that will continue to be mandatory is the duty to register the customer when they acquire a SIM card, in addition to being subject to number assignment regulations since that will not change with the eSIM,” said Gil.

The emergence of the eSIM will serve as a link to provide connectivity to the millions of connected devices that will be produced due to the great progress observed in the Internet of Things, said the Telefónica executive.

Among the advantages of eSIM, for Gil, the saving space for the battery stands out and, in the case of operators, it helps to manage connectivity “in a way more adapted to the 21st century and for millions of devices”.

Telefónica will bring eSIM to Spain

Among the service provision possibilities of this technology is a multiSIM option, to use the same subscription on several devices, something that will determine the commercial policy of the company that uses the eSIM.

The eSIM system has already been tested in some wearables, specifically watches that have shared a subscription with a mobile phone, so the question would be what is the next step for Telefónica?

Telefónica has been reviewing the use cases aimed at the consumer market: the customer can present himself with a high degree of independence from the operator, the device manufacturer or the supplier of the embedded SIM module.
