Fix Message "Not sent tap to try again" Error on Android | Solve Failed to Send Message

I don't have a sim card but came text other people just not a few don't understand why only some are like that
Thank you

Only works on cells from 2005-2013

My pixel 7 came with a 5g sim card. My Galaxy 9 sim card fit perfectly into the Pixel. But the Pixel needs the 5g card to work calls and texts.

Thank you, the aeroplane mode thing did the trick.

Some of those settings options don't appear in my phone (google Pixel 4a) tried them all but still having the same problem. A small clock appears under the text the disappears and the words 'Text not sent, tap to try again' re-appear.

Thank worked thank you

Both of these did absolutely nothing.
