I recently upgraded to the new Samsung Galaxy s5 and I won't receive text messages from my sister who has a iPhone 5S.
epaz831,We want you to be able to receive all your text messages! Did you previously have an iPhone? If so, unregister your iPhone from iMessages here... http://bit.ly/1hwkr1J Let us know if this helps.LindseyT_VZWFollow us on Twitter @VZWSupport
Did you have an iPhone before that? If yes then you need to log into you apple account and take your phone number out of iMessages
