To send a standard text rather than a message through Messages/iMessage on a per-message basis, just do the following on your iPhone:
Tap and hold on the message you want to send as a text. From the pop-up menu, select "Send as Text Message".
Note: Sending a message to a non-Apple device will always be sent as a text, at least unless the other user has an Apple messages compatible app running (unlikely as of 2023).
I usually write a blog post about once a week. The latest post can be viewed here: Between the Extremes: Maybe we are just doomed to alternate between the extremes. (posted 2025-01-09 at 21:34:30). I do podcasts too!. You can listen to my latest podcast, here: OJB's Podcast 2024-12-04 Avoid Microsoft: If you don't really like computers much you could make things a bit better for yourself..
