Apple Inc. delayed the launch of its new iPhone Air in mainland China, citing regulatory approval issues. When pre-orders for the new models began on Friday, the company’s China website would not let customers in the region order the new, thinner device. A launch in China is far more complex for the iPhone Air than it is elsewhere. Unlike the US, China is mostly reliant on physical SIM cards and hasn’t widely adopted eSIM technology, which the iPhone Air uses because of its thinner frame. When the iPhone Air was announced, Apple said that the device would initially only be available through a single Chinese carrier China Unicom and would require users to visit a physical carrier store to activate their eSIM and start using the device. Do you support eSIM technology use in china?
