Can texts disappear?

I have had texts from my husband appear after a week or so. He’s been able to show me them sent so he definitely wasn’t making it up. He does have an old Nokia phone, don’t know if that makes a difference.

I do not have a good signal where I live so texts often do not go through however it does say "undelivered try again" but not immediately.

Not so much these days but I used to find that, years ago, they didn't always arrive and have definitely had the experience of them taking a few hours to arrive.

I understand a delay but not a disappearance. Its so sad. Tryst gone.

I had this issue a month ago, none of my messages were sent, friends were cross, and two weeks later they received them all at the same time. O2 had no explanation

Sounds bull imo. Maybe last decade.

I don't think they generally disappear, but I've known texts take literally seven hours to reach the recipient.

One friend berated me on day for texting her at 3.30am. I had, in fact, (and could prove it to her) sent the text at 5.24pm.

I have found that some times text take ages to appear.

I have had texts disappear in the ether but not recently.
Check first that the carer has sent them to the right number.
