What is e-sim?
eSim full form is Embedded sim card. This little thing that allows your phone to connect to your cellular provider’s network. When you buy a new phone, you put your SIM card in your slot or buy a new one.
But, this eSIM card is completely different. Because, as the name suggests from the “embedded” part, it is actually built into the mainboard of the phone.
It is rewritable as an NFC chip and will be compatible with all major carriers, regardless of the type of network they use.
E-sim is not required to be installed on the phone, all the services of physical sim can be accessed through e-sim, it is a type of chip which acts like a sim card.
The e-SIM is installed with the phone develop and you cannot remove it. Also, you cannot install it on all devices. SIM is activated by telecom companies. Its specialty is that after changing the operator, you do not need to change the SIM card. The biggest thing is that there will be no need for SIM card slot in the smartphone.
And people who travel will benefit the most. Permanent SIM cards do not allow access to your number when traveling to other countries. In this way you can embed eSIM roaming in your phone. With this you will not have to pay roaming charges, most importantly, eSIM entitles you to use it while traveling to another country.
How does e-sim work?
If you have a physical and an eSIM and are connected to two different networks, your iPhone will show both networks on the screen at the same time. You will be able to put a second SIM with this small chip, that is, you will be able to use two numbers.
If you want, you can also change the network of the e-SIM and you will not need to remove this SIM. If you have bought an iPhone with Airtel e-SIM and you want to continue with the e-SIM, you can do so.
