This is NOT a carrier issue.
First if all,
there's no way the carrier can delete messages from your messages app. Second,
after a reboot the messages come back. So please stop with the take it up with
the carrier nonsense. This IS an iOS problem.
Secondly, I'm
having the exact same issue but it happens with BOTH (gasp!) iMessage and SMS.
My text messages
would show up for a split second and then disappear; Green bubbles for SMS and
Blue bubbles for iMessage would quickly vanish after I sent them. This problem
started happening after my phone lost sync with date/time (I changed the date
to 2012 accidentally). I reset the date and time and now messages don't
disappear anymore.
There were also problems loading webpages, I would always
get "Safari Can’t Verify the Identity of the Website" This occurred
because the system clock and date was not the current date, so SSL certificates
were being considered invalid. These messages stopped after I fixed the
date/time.
Here is a guide I followed:
Confirm
the System Time is Correct

If you’re still having the problem, your time
settings may be off. Yes, time, as in the clock on the computer. If that’s the
problem, it’s quite easy to resolve:
·
Be sure the iPhone has active internet
access, this is necessary to retrieve accurate date and time info from Apple
servers
·
Quit Safari
·
Open the iPhone settings menu and go to
General
·
Choose “Date & Time” and check the box
for “Set automatically”
·
Relaunch Safari
You should be good to go with no more verification
errors. This works for situations where the system time is reporting as vastly
different than what is expected from the remote server, like if a computer is
reporting itself from the future.
