If you are planning to buy the new iPhone 14, it should be noted that this time Apple’s US version of the iPhone 14 series completely cancels the physical SIM tray, all use eSIM technology, and switch to eSIM cards supported by AT&T, T-Mobile and Verizon.
For Chinese operators, mobile eSIM services have not been opened. Therefore, the US version of the iPhone 14 series will face the problem of not being able to use cellular networks in China. Some international students said that the US version of the iPhone 14 does not have a card slot, and if they return to China, they cannot insert a physical SIM card for use. In this regard, China Mobile, China Telecom, China Unicom, and China Radio and Television, the four major domestic operators, have stated that they do not support the mobile eSIM business, and consumers need to consider the purchase. According to Apple’s official website information, the national version of the iPhone 14 series will all be equipped with two nanoSIM card slots and continue to use physical SIM cards.
eSIM is an embedded SIM card, the full name in English is Embedded-SIM. eSIM turns a pluggable physical SIM card into a virtual SIM card that is embedded directly on the device chip, providing identification for each terminal device and enabling it to access the operator’s network.
The eSIM can further save space inside the phone, making room for other components such as the processor and battery. However, it is more troublesome to change the mobile phone number of the eSIM, and you need to go to the business hall or use another mobile phone to scan the code to replace it.
