Huawei's NM memory card (referred to as NM card) is an ultra-miniature memory card with Huawei's own patent. Compared with Micro SD memory card, its size is reduced by 45%, and its specifications are almost the same as Nano SIM card. When using the NM card, you need to occupy a Nano SIM card slot in the mobile phone, which can expand the storage of the mobile phone. At present, Huawei's mid-to high-end mobile phones and tablets have been basically covered, and more smart devices will be added in the future. Please remember to check whether your device supports NM card expansion before purchasing.

1. Installation steps/methods of Budweiser NM card:
1, installation method
Take out the SIM card holder of the mobile phone with the given card pin, put the metal face of the 100-dimensional NM card upward into the card slot marked with the NM card icon, and insert it into the mobile phone.
2. Select the priority storage location.
In Settings → Storage → Memory Card, you will be prompted to format the memory card, and click OK. The default storage location at the bottom is "external storage card", so that the new data generated by the mobile phone will be preferentially stored on Budweiser NM card.
Second, mobile phone data backup/data recovery
1- 1, data backup settings:
Budweiser NM card can be set in two modes: manual backup and automatic backup, which can be backed up many times and automatically encrypt backup files. NM card is faster and safer than cloud backup.
The operation process is as follows: click Settings → System and Update → Backup and Recovery → External Storage → External Storage Card → New Backup, and then select the data folder to be backed up. When backing up data for the first time, you need to set a password.
1-2, set automatic backup:
Refer to step 1- 1, open the automatic backup option, select "automatic backup", and check the data items to be automatically backed up. In this way, when the charger is connected and the power reaches 75%, the mobile phone will automatically back up the pre-selected data every 7 days.
2. Data recovery
When the mobile phone is used for a long time, there will be problems such as APP redundancy and unsmooth system. At this time, we can back up the mobile phone data, reset the factory settings of the mobile phone, and then restore the needed data to make the mobile phone as new. In addition, when we need to upgrade our mobile phone or replace it, we can directly restore it to the new mobile phone from the previous backup data to ensure the security and convenience of the data.
The operation flow is: enter system update → select backup recovery → external storage → external memory card → select data to be recovered, and then click recovery → enter password to complete the recovery of backup data.
Budweiser NM card has excellent performance, with a reading speed of 90MB/s and a writing speed of 83 MB/s. In the actual measurement process, with its excellent random writing performance of 4KB, it can achieve the same performance experience as the built-in storage of mobile phones.
Summary:
The installation and use of Budweiser NM card is not complicated, but a Budweiser NM card can make your mobile phone capacity look brand-new, and at the same time, it can safely back up mobile phone data so that everyone can be prepared.
