My IPhone 6 won't text one person?

My IPhone 6 won't text one person, I can receive texts from them but I can't send texts to them. IMessage works but I want to send SMS, we both have reset our phones. I don't know what to do.

Go to settings > messages > and then try turning off iMessage and then send it! If that doesn't work then hold the power and home button until your phone turns off! Then turn it back on!

  • Why won't one person get my text messages So I can text everyone except one user I have an iPhone with verizon and she has a iPhone with Verizon and she tells me she texts me but I don't get them and she doesn't receive mines either we get them sometimes not all the times it's bothering me not talking to her i don't know if its my phone or her phone or it's Verizon's network is anyone have problems with this?
  • Why can't I text or call one person? Me and my friend both have an iPhone 6, and he can text me, but I can't text him. When I text him it doesn't deliver, so I click 'send as text message' and he doesn't receive that either. I can text other people fine, but not him and I can't figure out why. I also can't pick up Facetimes from him which is also an issue.
  • Text won't go through to one person? I have an iphone and the person I'm trying to text does not. I tired texting him and it keeps saying that it wasn't delivered. All my other texts go through to others. I tried calling and their phone rang. I don't know why this text won't go through. Anyone know why this might be?
  • One Person Not Receiving Text messages? So I have an IPhone 6 and he has an android and out of no where he stopped recieving my texts. I get all of his messages but he can't receive mine. I've tried restarting my phone, and re entering the contact but nothing worked.
