The Esim is an evolution of the traditional sim card which is known worldwide for being the one that provides connectivity with communication networks, allowing calls to be made and the Internet to be used through mobile data.

These cards are usually inserted into a special slot found on the sides of smartphones. It was invented and later launched on the mobile phone market in 1991, date from which it has sought to reduce its size and improve connection capacity. The three models of Sim cards that have existed so far chronologically are the Minisim, Microsim and NanoSim.

Although some cell phones and smartwatches already incorporate this mobile phone technology, it is expected that with its gradual introduction in the world market, all cell phones will be redesigned, ceasing to exist the usual slot in all future devices.

At least in Latin American countries such as Colombia, its use is not widespread, it is expected that over the years most citizens will use it because it promises to double the data capacity of current Sim cards.

Nevertheless, eSims work in Colombia since December 2018 with the arrival of the Apple Watch Series 4, which was the first device to handle this technology in the country.

In fact, the devices in which this technology has been especially useful are smartwatches, which will no longer take calls from the Bluetooth pairing with the cell phone, but will do so from their own software, improving the quality of the calls.

In any case, the existence of these sims that will operate in the cloud is not a particularly recent innovation, in fact this technology was presented in 2016 by the Association of mobile operators, GSMA.

Both the developers of this technology, as well as the telephone companies around the world, suppose that the introduction of these virtual Sims in the systems of mobile operators, It will bring significant benefits to users apart from improving connectivity.
