Re: Whyu do most texts come 2 or 3 times, identical text, identical time sent?

Why do I get most of the text messages 2 or 3 times, identical text,
listed in Details as sent at the identical time.
 Usually doctors or businesses send 3 times but today I got two from a
friend and both came twice.
   And strangly if you call them F(irst) and S(econd), they display in the
reader as F, S, F, and S. so the second F was send 20 minutes before the
two S's, but it displays after the first S.
 Until recently I didn't know how to tell when they were sent, but now I
do know how.
