Ive had this problem off and on with 2 phones now, and with 2 SIM cards. Why do i recieve sometimes only 2 but as many as 8 the other day, of the same text message with the same time and date from the same sender? my clock is often ahead of the time on the message when i recieve the duplicates. Why does this happen and what can i do to stop it? it happens with more than one contact. I was using the samsung evergreen, and have since migrated to an unlocked samsung captivate glide, on a new SIM card. had this problem on both phones. Anything i can do?
