iMessage is enabled, but not working
I just started getting a popup saying that iMessage needs to be enabled for me to send a few photos on a group text. I can't seem to send photos at all. My iMessage is enabled. My phone number is selected to send and receive. I closed out the app, and tried again. Restarted my phone and tried again. Wifi is working well. I have good reception. What is going on?!
