iOS Messages app not forwarding SMS messages to Mac
Within our family, three individuals have both an iPhone and a MacBook Pro. Four days ago, the three individuals moved from AT&T to T-Mobile. They still receive iMessages and SMS messages on their iPhones, but the SMS messages no longer forward to their respective MacBook Pro.
We've checked all the settings in the iOS and Mac Messages apps, we've reset the network settings on our iPhones, have logged out of our respective Apple ID's on the devices and logged back in, and have off turned off all devices and turned them back on, but the problem still persists. We also have spent an hour on the phone with T-Mobile, but they can't figure out what's wrong either.
Has anyone encountered this issue? And thoughts on solution?
