The latest iPhones XS, XS Max and XR all come ready with something called the digital eSIM.
What the eSIM does is that it allows users to subscribe to a mobile plan from the service provider without the need for a physical SIM card.
In short, dual SIM function with only one SIM card.
For M1, they have just become the first operator in Singapore to be digital eSIM ready.
The advantage of using an eSIM is similar to that of putting in two SIM cards into the smartphone.
Customers can assign it to be used for data or voice calls, making it convenient for frequent travellers.
Currently, the only eSIM supported devices are the latest iPhones that are updated with iOS 12.1.1 or later.
You can now head down to M1 Shops, Exclusive Distributors to sign up for the eSIM.
