How does Nokia 5233 delete SMS in batches?

Method 1: Select a short message, and then click Options-Mark/Unmark-Mark. This marks a short message. And then mark other messages, it's much easier. Click the other message you want to delete twice-Mark/Unmark-Mark. So you can mark all the emails you want to delete, and finally click Options-Delete.

Method 2: Click the information icon-Options-Settings-Other in the menu, and set "Display information in groups" to Yes. When you check your inbox again, your messages will be grouped by date. Select a date and click Options-Delete to delete the message of that date.

I use the second one, which is convenient for browsing and deleting.
