Both my wife and I have IPhone 6s. When I text her, I get the normal swoosh and my message screen is updated but she never receives the message. However, she can text me. We brought her phone in mid-may so I am not absolutely sure i was ever able to text her. I am not aware is this problem with any other phones but it is hard to tell. Most other text do appear to go through. Any thoughts as to cause/fix? For what it is worth, my carrier is Sprint.
