My imessage is not working on my phone 🙁 In the messages settings, when I turn 'imessage' on, it says 'imessage activation unsuccessful' Then if I go into send and receive, and press my number, it loads for a bit, but never works. I need help because Now when I send imessages to people, it comes up to them as my email address. It's only if I send a message to them in green, they will see it. But sending as a text message will not allow for me to be in group chats. It's also affecting how people text me, because generally people text using imessage, and I will not receive it, if someone is using imessage to text my phone number.
Hope that all makes sense.
