Why does the mobile phone always prompt that the SMS memory is full?

There is too little memory left in the mobile phone, so you can delete some pictures, music and unused software.

What should I do if the storage space of my mobile phone is insufficient?

1.SD card capacity problem. Sd cards generally store large files such as promotional video documents. If the file is important to you, the best choice is to change to a larger sd card. Because in terms of price, cards with large storage capacity will not be more expensive. The average mobile phone can support at least 16g or even 32g of extended storage. So generally speaking, peripheral storage is not short of memory.

Of course, if the memory is still insufficient, then you can clean up some unnecessary files. Film and television files are generally the files with the largest number of volumes, so it is naturally impossible for a movie to be played repeatedly. So just clean up some unnecessary files. The memory of sd card generally affects the lack of memory storage space when we take pictures, which leads to the inability to store the desired good photos. So it's best to leave at least 25% space for your sd card.
