What is an eSIM and how can I enable it in iPhone.
An eSIM, or Embedded SIM, is a digital SIM that is built directly into a device, such as a smartphone or a tablet, instead of requiring a physical SIM card. With an eSIM, you can activate a mobile phone plan without the need for a physical SIM card.

To enable eSIM on your iPhone, you will need to follow these steps:

1. Check with your carrier to see if they support eSIM for your device.
2. Go to Settings on your iPhone.
3. Select Cellular.
4. Tap Add Cellular Plan.
5. Use your iPhone to scan the QR code provided by your carrier.
6. Follow the prompts to activate your eSIM with your carrier.

Once you've completed these steps, your iPhone will be able to use the cellular plan associated with your eSIM. You can also switch between eSIMs by going to Settings > Cellular and tapping on the plan you want to use.
Help! My daughter switched carriers for some reason using your method, and now it's impossible to track all the finances! How do I set her back onto the family plan? Am I going to have to pay extra for all the messages she sent and movies she watched...?
