Greetings, NoahWhite2014-I have been struggling with the same issue for the last couple weeks. In the last 3 days, I have endured 3 phone conversations with Apple CS reps, and wasted 5 hours doing so. Have done a reset, restore, cut off, back on, etc.All tell me that iMessage ALWAYS had to have both senders and receivers of text messages to enable iMessage on an iPhone in order to be able to send text to others with an iPhone via a wifi connection instead of using cell data. What CRAP. For the last 3 1/2 years, I have used only wifi when at home (and where available) to send and receive texts to others using my home wifi.. Now, seemingly after the 8.3 update, the "rules" have changed. I am ready to leave Apple at this point. I have a 5c with the 8.3 iOS.I have checked all appropriate settings-iMessage, SSM, MMS, etc. When I scroll to "send and receive" only my email (Apple ID) is checked. My phone # is NOT checked, is greyed, and I cannot check it.I do have my phone # checked as "start new conversations from.. ". I suspect there is a software glitch in the update, but certainly Apple reps are refusing to say. Does anyone have any solutions? Help! Huge thanks in advance to any/all who can proffer a solution.
PS- I am not traveling nor trying to use my phone for out-of-country calls. Strictly domestic calls.
