I changed my phone number a couple of days ago, and when I try to text non-iphone users, my messages fail to send. I have tried restarting the phone and deleting the thread, and nothing works. I have an iPhone X, and the issue seems to be limited to SMS and not iMessage. I can receive SMS messages, but cannot reply.
I depend on my messages as it is my main form of communication. Please reply to my private note to further assist.
