SMS not delivered if receiver offline at sending time

Yes that's normal, the validity period seems to be something like 2h.

Yes now I see it. Thanks for your work! This is actually quite big bug if you think how people expect phone to work.

I cannot comment in the upstream bug report because I have no account on puri.sm, but I think I found the place with the issue:
https://source.puri.sm/Librem5/chatty/-/...nt.c#L1454
This is setting the validity period to 168 something. (The unit is not documented.) Since you found it to be around 2 hours, I guess the unit is minutes.

Please forward this information upstream, I think they should be able to fix the issue quickly with the line pinpointed like that.

I think it should be safe to just delete or comment out that line. As far as I can tell, Spacebar just leaves the timeout at the default, and ModemManager then does the right thing.

i can confirm this issue, and validity time is somewhere in 2 hours. tested on pinephone to pinephone.

The validity time is exactly 2 hours and 50 minutes. 168 minutes = 2 hours 48 minutes, but it gets rounded up to the next higher timeout supported by the GSM standard, which is 2 hours 50 minutes (timeouts less than 12 hours have 5 minute granularity).
