Not receiving short codes
I have an iPhone 7. I’m updated to iOS 15.6. I recently traveled to the UK and used a local SIM card for two weeks. When I returned and replaced my AT&T SIM, I seemed to stop receiving short codes. I can receive other messages and even received longer text codes when AT&T tested that. I’m loathe to do a Network settings reset, as I have so many WIFI password saved and I have to go through hoops to get t work WIFI back! Any thoughts? Ideas?
