Alongside the new line of smartphones that Huawei launched at their big event in London, was the unveiling of a new memory card format – called the Nano Memory Card or NM card. This new card will replace the traditional microSD card in the recently announced Huawei Mate 20 and Mate 20 Pro.

Also confirmed during the event was that Huawei has collaborated with Toshiba, who has promised to manufacture the new NM cards.

The new memory card format will go in one of the slots on the dual-SIM tray available on the Mate 20 and Mate 20 Pro. The dual-SIM card tray gives users the ability to choose between either more storage or a second SIM card.

Although Huawei has not yet released many specifics about their new card, we’ve accumulated all the details we know so far. So carry on reading to find out more about the new NM card.

NM Card size:

Identical in size and shape to a Nano SIM card, Huawei has stated that the NM cards will be 45% smaller than a standard microSD card.

NM Card capacity:

Huawei didn’t unveil the capacities of the new cards, however, they did state that the new flagship phones will support at least a Nano memory card of up to 256GB of storage and up to 90MB/s of transfer speeds. Presumably, the card will be available in various storage capacities to give consumers an option.

NM Card standard:

As the company hasn’t given much away, there is an assumption that the Nano-Memory card is merely a new shape for a microSD card, which in theory would enable it to be used in other devices via an adaptor. However, so far there has been no indication as to whether the brand plans to introduce this card as a new industry standard for a storage format or if it will be used by other smartphone manufacturers.

Pricing and availability:

The tech giant has yet to disclose how much their new NM cards will actually cost or when they will be available to purchase. But, be sure to keep an eye on this article, as we will be updating it as more information appears.

    When i vist your website to see what you offer the first thing i see is “Huawei Mate 20 Pro Micro SD”. Are you offer incompatible memory cards or what???

    1. Hi Hristo,

      Apologies for this. Please find the correct link attached which display the correct cards for the Huawei Mate 20 Pro. https://www.mymemory.co.uk/huawei-mate-20-pro-memory-cards-and-accessories.html

      Kind regards,

  3. Not happy about this move at all…. I already have a 256GB MicroSD card in a Mate 9 and for me to fork out EVEN MORE MONEY if i wanted to upgrade to a MATE 20 Pro and have the same memory capacity is just a dumb move.

    If they were going to do that then they should have taken the entire phone design right back to the stone age and used their own proprietary charger and data cables instead.

    Theyve just lost a customer…. Sony did the same thing with some of their PSP’s and that was one of the reasons why the PSP sold badly.

    Im being forced to settle for the Mate 20 Lite if i want to use my existing microSD card. What they are doing is PUNISHING the customer for not buying their memory card. Mate 20 Lite is still a good phone though but it doesnt have all the bells and whistles as its bigger brothers and if i wanted the pro model, WHY SHOULD I SETTLE FOR LESS?????

    Bye Huawei, I’ll go buy a Xiaomi or Samsung handset as my next upgrade.

  4. Alongside the slate of new phones Huawei announced today was an interesting addition: a new type of expandable storage the company is calling Nano Memory (NM), which replaces the traditional microSD card in the newly announced Mate 20 and Mate 20 Pro.

  5. huge problem over all this is there is no way to use the slot for both memory card and sim.
    this is one huge floor of which Huawei will loose out should they not fix all this
