E-SIM
SIM cards have not undergone much change since their inception in 1991. With the new SIM technology, the size has become smaller and become nano, micro, but its basic concept has not changed much. It means that the size of the SIM cell of every mobile phone has decreased, so the SIM has become smaller, but the shape of the circuit has not changed. The card has survived so long in the technology wars, but now it's time for its retirement. E-SIM or Embedded SIM is going to replace the current SIM card.

What is e-SIM?

Before talking about e-SIM let's talk about how SIM works. SIM is the full form of Subscriber Identity Module, i.e. it carries the identity of the user. A SIM card confirms your identity to the SIM carrier or SIM company. As a result you can enjoy the network and benefits of that carrier. When this is not possible or an error occurs, your phone disconnects from the network.

A SIM has an International Mobile Subscriber Identity (IMSI) Number which is completely unique or a unique number. This number is sent by the mobile phone to your preferred SIM network, allowing them to identify you. It also has an authentication key, which makes it impossible to send false information.Difference between E-SIM and Normal SIM-

E-SIM works in a similar way, but these SIM card technologies are built into the phone. Simply put, as the processor is embedded in the phone's chipset, so is the SIM. That is why it is called EMBEDDED SIM. Normally we can't see it or figure it out. In a regular SIM this information is written at all, but in an e-SIM this information may vary depending on the SIM carrier. That means you can easily change your network information from one network to anotherPeople who travel will benefit the most with e-SIM.

It is a labor-saving addition not only for users but also for SIM companies. Both time and resources will be saved in SIM production and distribution. No need to rush to buy a SIM.
