Mobile phone can't send text messages. When sending a text message, it prompts "insufficient memory" but the phone has more memory. How to solve this problem?

At present, there are two kinds of mobile phone memory: RAM dynamic memory, commonly known as running memory, which is the same as the memory in the computer; ROM used to be called static memory. With the development of science and technology, today's Roms usually refer to non-volatile memories, or they can still save data when power is off. Also called mobile phone memory, it is used to store the mobile phone system and some user data (including programs installed by users). Its function is basically the same as that of hard disk, but hard disk is definitely not ROM.

Usually, the mobile phone prompts that the memory is insufficient. Generally, there are too many mobile phone applications or too many mobile phone cache files. Just clear the cache or close a few applications.

The easiest way to release memory is to turn it off before turning it on.

If not, your mobile phone memory is too small.
