An eSIM is a digital SIM that allows you to use an additional SIM within your phone without inserting a physical SIM card inside your phone, basically an embedded SIM.
By using a Dual SIM enabled phones, you can make and receive calls via two numbers from your single mobile phone device.
iPhone models supporting dual SIM are: iPhone XS, iPhone XS Max, iPhone XR or later.
iOS 12.1 or later
What is required to use a dual SIM from two different carriers in your iPhone (models above):
1. An unlocked iPhone. If it is not unlocked, your both plans have to be from the same carrier.
2. An eSIM subscription from your preferred carrier. Your selected carrier will provide you the eSIM details upon subscription
Apple website display a list of wireless carriers from various countries that support eSIM – Wireless Carriers that offer eSIM service
Always recommended to check with your preferred carrier if they provide eSIM.
The biggest advantage of using eSIM I have ever seen is for the people travelling overseas for work, education etc and need to have a mobile plan from their home country. I use eSIM from India mobile provider to receive OTP, banking transaction messages etc from India onto my iPhone in Australia.
