So I just got a replacement iPhone, and activated it. I tried sending a text message and it wouldn't go through. I went to my messaging settings and clicked send and receive, and it had my phone number and email under "you can be reached by message at." However, next to my phone number, it had the loading wheel and there was no option to "Start new conversations from."
I reset my phone and when I try to click "use your apple id for iMessage and sign in, it says that I can't connect to the server.
Is there a way to troubleshoot this or alternate steps?
