Yesterday, a message from a user ctthrow1 on the Reddit forum that iPhone 12 only supports 5G under a single card, and cannot support any 5G network with a single SIM card under dual-SIM dual-standby. Is the same with the National Bank iPhone 12? Xiaobai’s evaluation is not true.

As you can see in the figure above, earlier news broke that Apple’s internal sales training document FAQ information provided to carrier partners showed that using iPhone 12 in dual-SIM mode will limit the mobile network data speed to 4G (LTE).

As you can see in the picture above, Xiaobai’s evaluation of the Bank’s iPhone 12 supports 5G in dual-SIM mode , but does not support simultaneous use of 5G (the same is true for most 5G phones in Android~). It is guessed that the dual-SIM of the foreign iPhone 12 series is mostly physical Card + eSIM card combination, the Bank of China is a physical dual card. Anyway, the Bank of China iPhone12 supports 5G under dual cards.
