I have my google pixel 7 phone... I've been using it for a couple of months now (Switched from a Samsung s10 where I had no messaging problems). Messages sent and received by this phone was working great until this past Wednesday evening (6/28/23). Everything explained in the comment of this ticket (and it's responses) https://community.verizon.com/t5/Samsung/My-Android-Messages-not-being-received-by-iPhone-users/td-p/1688793 is nearly identical, except that none of my SMS's are received by any iphone users, but all MMS group messages are. I've tried using Messages + and Google messages with the same results. I also cleared cache, removed and reinserted Sims card, reset API, uninstalled/reinstalled messaging apps, etc. etc. The only way I can get iphone users my text messages from my pixel phone's verizon number is to create a group text, using my google phone number and the iphone contact I'm trying to send my message to.
I was hoping the solution to resolve the January 2023 Samsung issue (url posted earlier in this message) would be posted, but it wasn't. Help! This is super frustrating.
