@dhansenWhat happens when you call your phone number from another phone? Can you access your voice mail? If it is not what you expect, you might had been SIMjacked.
Just an off chance what happens when you swap your SIM card to a known working phone?
Did we not have this exact same issue yesterday with someone else and it got solved? Or maybe it was solved by reaching out to a moderator....try doing a search using your subject entry.
