Xiaomi Mi Smartwatch e-SIM Calling Function: What’s eSIM and eSIM One Phone Number Dual Terminal?

The Xiaomi Mi Watch smartwatch supports the eSIM calling feature, and perhaps everyone knows that the smartphone can make a call, provided that a SIM card is installed, but you may not know much about how the smartwatch makes the phone calls. Now let me explain to you a noun and two ways to make a phone call on a Xiaomi Mi smartwatch.

If you look at the name, you may guess that e-SIM can be understood as a SIM card technology. eSim stands for embedded SIM. It’s a software solution instead of a physical one. Except that it is a chip built into the device, and all communication information such as operators and telephone numbers can be written in the later stage. Thus, the "card number separation" (the separation of SIM card and number) is realized.


The main difference is that an eSIM is a digital SIM while dual SIM is a phone that physically has two SIM card slots. With eSIM, there’s no need for one or two SIM cards.


Instead, your eSIM activates a mobile plan without having to use a physical SIM card. That eSIM is stored digitally in your Xiaomi Mi Smartwatch. In other words, with eSIM, you don't have to buy a physical SIM card alone, and you avoid tedious steps such as card replacement.


The previous introduction to "SIM card and phone number separation", so the question arises, after we bought the Xiaomi smartwatch, which phone number is used in the smartwatch? There are two ways.

Independent telephone number and one phone number dual terminal

One is the "independent number", which is equivalent to start a new number, and when someone else calls you, they can only call to the Xiaomi smartwatch. The advantage is that it is more independent, the watch is dedicated, and can be used as a spare number. And some operators already support this number as an accessory number of mobile phone numbers, sharing voice and traffic resources with the main number.


But many friends said, I do not want two numbers, I want my smartwatch and mobile phone use the same number, this is the "one phone number dual terminal". The two terminals share the same calling package. When the phone comes, both the Xiaomi Mi smartwatch and the mobile phone can receive the phone call. You can use whichever call you want, and the effect is the same.


As to which one we choose, in addition to looking at our own needs, the more important thing is to see whether the equipment is supported or not, whether the operator supports it or not.


You can guess whether Xiaomi Mi smartwatch can support both ways at the same time. The answer will be announced at the press conference tomorrow.
