My mobile phone always prompts that there is not enough space when replying to short messages, but the card still has a lot of memory. Is there any problem?

The first case: you can enter the' Options'/'Settings'/'Other'/'Storage in Use' and' Information Storage Quantity'/of the short message first, and you need to know the answer for the information!

In the second case, you switch' in-use storage' to see if the SMS in the mobile phone storage (memory card) is almost full.

I can't think of any other possible situation!
