What is an eSIM, how does it work and ways to activate Jio or Airtel eSIM on your Apple iPhone

Apple launched the much-awaited iPhone 14 series at the Far Out event on September 7 and since the launch, the iPhone 14 Pro and iPhone 14 Pro Max have been the part of the news due to their new features and upgrades. One of the most talked about features in Apple iPhone 14 Pro models is the lack of SIM card slot. Apple has announced that iPhone 14 Pro models sold in North America will not have a SIM card slot. This means that the new ‘Pro’ iPhone models will be dependent on eSIM technology.

For those who are unaware, eSIMs are not new to iPhones and have been seen since the launch of the iPhone XS in 2018. Till now, the feature was only available for secondary SIM but the iPhone 14 series marks the beginning of a new era of eSIMs. But what is an eSIM and how does it work? Here's the answer to all your questions.

What is an eSIM?

An eSIM is a SIM card that is embedded in a mobile device. Additionally, the eSIM functions similarly to a conventional SIM card without requiring a real SIM card to utilise it. The "eSIM profile" of a new operator must be installed in order to activate it because it is already pre-installed on the device. In reality, it is a development of the traditional SIM card. An eSIM card is a feature that is being added to more and more smartphones, tablets, and computers.
