Apple mobile phone deletes SMS at one time? How to delete SMS in batches on iPhone? IPhone mobile phone bulk deletion SMS tutorial.

When I opened the "Messages" of the iPhone, I found that there were nearly a thousand messages, 99% of which were spam, express messages and verification codes ... Unfortunately, the iPhone had the option of "reading all" but not the option of "deleting all".

It is a waste of time to choose to delete one by one; Leave it in the phone and waste memory. Is there really no way for iPhone to delete these "junk" in batches?

There really is. Open the phone "Settings" and swipe down to find "Messages". In the "Information" interface, slide down to find "Information History".

To modify the retention time, select 30 days or 1 year, and then click Delete.

Restart the phone. Then click "Info" and slide to the bottom. The farthest message I found was April 6, 20 18, about a month ago. Next, you just need to manually delete this month's messages.
