The NM card is a memory card developed by Huawei itself, which has higher transmission speed and larger storage capacity than traditional microSD cards. The 256GB capacity is enough to store a large number of photos, videos and files to meet users' storage needs. Whether it's taking high-definition photos or downloading large applications, the Huawei P40 provides enough storage space for users to enjoy more convenience and fun.
