Apple internal training document exposed: iPhone 12 dual-SIM mode cannot turn on 5G

This year, all iPhone 12 series use dual SIM dual standby, with the only exception being the Chinese version, where the iPhone 12 mini uses a single SIM card. Of course, the dual SIM cards of other Chinese models are also different from those in foreign countries. The former is a physical dual SIM card, while the latter is a physical SIM+eSIM.

However, screenshots of FAQ materials allegedly from Apple's sales training documents appeared in foreign communities, which showed that in dual-SIM mode, users cannot turn on 5G and the network speed will drop back to 4G.

In other words, if you want to return to 5G, you must turn on the single-card mode, that is, block one card in the dual-card state.

Of course, this refers to foreign physical SIM+eSIM models. Whether the domestic models are the same can only be confirmed after they are delivered.

Some netizens said that Apple is also aware of the inconvenience caused to users by the above restrictions, and will enable 5G dual-SIM dual-standby mode through iOS 14 software updates in the future.

Currently in Android, there is no coexistence conflict between 5G and dual SIM cards. Even in the MediaTek Dimensity platform, two cards can be on standby in the 5G network at the same time, which is more convenient.
