According to Huawei, the NM Card comes in different storage options, and the company did showcase the 256 GB variant of the NM Card at the launch event.

Why Huawei Mate 20 smartphones use the nano-memory card?

With the nano-memory card, Huawei will be able to cut down on the slow down process of the smartphone due to the read and write speeds.

Nano-memory Card price?


There is no information on the pricing or the availability of the NM Card. However, the NM Card will be available along with the Huawei Mate 20 series of smartphone.

How to use the nano-memory Cards?

Do other smartphones support nano-memory card?

As of now, there is no information on this aspect. If the nano-memory card becomes mainstream, then other smartphones manufacturers might also implement this feature.
