They provided sequential switch speeds of 90MB/s reads and 60MB/s writes. Not as quick as a few of the greatest microSD playing cards even in 2020, however not terrible both.

In addition to extending storage, these playing cards functioned as backups too and will assist when transferring to a brand new cellphone the carriers that supported the format launched an app that may retailer your handle ebook, pictures, apps and different information on the cardboard, able to be restored on a brand new cellphone, all with out touching the cloud.
So far as we will inform, there was no digital connection between the SIM portion and the microSD portion of the cardboard, this was only a 2-in-1 package deal. And because it seems, some enterprising people made their very own SuperSIM playing cards years earlier than carriers got here out with an official product.

The unique NM playing cards topped out at 256GB capability and that hasnt modified 5 years later. The most recent Mate 60 telephones nonetheless assist NM, however no different maker adopted it moreover Honor (however this was earlier than the cut up).
