The revealer @changan digitaljun recently revealed the internal structure of this mobile phone case, but it is a little blurry, it seems to be the place where the SIM card is inserted. And hinted that it may be from the hands of third-party manufacturers.
Moreover, it is not clear how Huawei uses the mobile phone case to support the 5G network, but Motorola has previously launched a module that supports the 5G network for the Moto Z3, and the built-in Qualcomm Snapdragon X50 baseband now supports 5G.
