Hello dear Vivoicer!!

Do you know what is E - sim ?

Technology is updating lot in our day to day life ,

Some of the tech are beyond imagination!!

But do you know this technology related to your smartphone!!

E - sim ,know what it is And why is it used for !!

An eSIM (embedded-SIM) is a form of SIM

card that is embedded directly into a device.

Instead of an integrated circuit located on a

removable SIM card, typically made of PVC, an

eSIM consists of software installed onto an

eUICC chip permanently attached to a device. If

the eSIM is eUICC-compatible, it can be re-

programmed with new SIM information.

Otherwise, the eSIM is programmed with its

ICCID/IMSI and other information at the time it

is manufactured, and cannot be changed.

Different mobile telephones may not support an

eSIM, may have a permanently programmed,

unchangeable one, or one that can be

reprogrammed for any carrier that supports the

technology. Phones may support physical SIMs

only, eSIM only, or both. 

Once an eSIM carrier profile has been installed on an eUICC, it operates the same as a physical SIM, complete with a unique ICCID and network authentication key generated by the carrier.

The eSIM standard was first released in 2016; since that point, eSIM has begun to replace physical SIM in domains including cellular telephony.

What do you think of E - sim evolution in technology services!!
