My Nokia 5230 displays the word "General: Used" when deleting a read SMS, and it cannot be deleted. What do you mean? How to solve it?

Solution: First of all, the mobile phone can be XX or not. Install the X-Plore file browser and open C: \ private \1000484b \ Mail2 \ (Figure 2). Basically, all the information is stored in the 0000 100 1_s folder under Mail2. This folder is stored in 16 base, which contains 0-. You need to find _PAlbTN or some other attached files in these folders, which is easy to find. Open a folder in (0-9, a-f) as shown in Figure 3. If you find that there is a+sign in front of those folders (if there is no+sign, you don't need to pay attention). When you put a+sign, you will find the above-mentioned (Figure 4)(_PAlbTN or some other attachments) in it. You can delete it directly, just delete the _PAlbTN file. Some pictures may be your MMS or something. If you don't want to use XX mobile phone or operate on it, you can change the SMS storage into a memory card in SMS settings, and then use a card reader to operate on the computer according to the above method (the computer needs to set up a display system to hide files). After the operation, put it back on the phone and change the message back to the phone for storage. I hope it helps you!
