Why are my messages turning green and iMessage won't work with my phone number?
My messages are all green, no matter if someone I'm texting has an iPhone or Android. I have made sure my iMessage is on, I have good wifi/service, I have restarted my phone a lot, and I toggled all of the buttons on settings to fix iMessage, but it won't work. This has been happening for almost a month. My messages only show up blue when I connect my email instead of my phone number to iMessage. It will work for like a day and then go back to green. It shows up RCS, MMS, or SMS and only green. Also, if I turn off MMS or RCS, then my FaceTime won't work, so obviously I have to have those on. I just want my messages to work and be blue LOL. I don't know what to do, someone please help.
