Not receiving verification codes via text
IPhone 11 Pro with iOS 15.5, T-Mobile. I am not receiving texts from providers sending a verification code (Social Security, Simplisafe, my credit union, etc) and I get “not delivered” messages when texting someone who does not have iMessage, though some of the texts are getting through even with the “not delivered” message. Seems to have started about 2 months ago. Need to both send to non-iMessage folks and get verification codes (that one has me baffled).
