What exactly is an eSIM card?
First of all, the SIM card inserted in the mobile phone should be something that everyone is familiar with.
But it's not only buying a new phone or applying for a newcellphone numberYou can only see it when you are, and it is almost hidden in your mobile phone at other times.
After several years of evolution, from the traditional big card (mini SIM) to the medium card (micro SIM), and then to the fine card (nano SIM), these three are "physical cards"▼

- As for eSIM, it is written as Embedded-SIM, which can be called "embedded SIM card" in Chinese.
- But if it is called "built-in SIM card", it may be better understood by everyone.
- Because eSIM is a SIM card specification that can be activated remotely, there is no physical card slot.

Currently, there are smart phones that support eSIM function, namely Google Pixel 2 series, and Apple’s iPhone XS (excluding the licensed version in mainland China), iPhone XS Max (excluding the licensed version in China, Hong Kong and Macau).

- The iPhone XS can hold up to eight eSIMs, but only one eSIM can be used at a time.

Can an eSIM card be used in mainland China?
In 2018, China Unicom obtained the pilot support for the eSIM No. XNUMX dual-terminal business, but currently there are very few Chinese cities that support eSIM card services...
Because of the emergence of eSIM cards, users are very easy to switch to other mobile phone operators. Maybe Chinese mobile phone operators are worried about the loss of users. Therefore, iPhone XS and iPhone XS max users in Mainland China cannot use eSIM cards.
