Apple seeks to lure customers
Firm files applications to patent its dual-SIM card technologies, enabling one phone to support two carriers
Apple Inc has filed two patent applications in China, in a move to prepare for new smartphone features that can resonate with local consumers, as the US giant struggles with tumbling sales and mounting competition in the world's largest smartphone arena.
The California-headquartered firm filed two applications to patent its dual-SIM card technologies in China, which enable one phone to support two carriers at the same time, according to the official website of China's State Intellectual Property Office.
