NM (Nano Memory) Cards

About NM (Nano Memory) Cards

NM memory cards are an expandable storage format that was announced by Huawei in October 2018 when they launched the Mate 20 and Mate Pro 20 smartphone. At the time this new memory format had yet to be approved by the SD Card Association. NM cards were introduced to replace the microSD slot on Huawei smartphones, and instead fit into the dual SIM card slots, utilising what has become a more common feature on smartphones.
