I keep trying to backup my SMS messages and it will never go past about 1 500. I have gone and deleted the really old ones thinking that maybe there were too many  but that didn't help. I have tried everything but it simply won't backup anything that's happen since May of 2015. I am trying to back them all up (to my gmail account) so that I can delete them all off my phone but still have a search-able record of them...
