One way text message
I only have a problem sending sms messages to one person, I receive all of the messages they send me but they don't receive mine even though I dont get a '!' for the failed sending. I have a 5s they have a galaxy 4, Sprint is our provider. I have done the basic trouble shooting (restarting phone, toggling imessage on and off, and other message settings) We were able to send them at one point in time so I'm curious if it has to do with an update or something. Thanks for any help
iPhone 5s, iOS 8.1.3
