Anyone have this problem and get it fixed before? I’ve been Googling for like an hour lol.

Tried out the Galaxy Z Flip 5, loved it but really didn’t love Android. I factory reset and returned the phone. Now I can’t send or receive text messages on my iPhone because apparently I had to disable RCS before switching back. Tried filling out this form to disable it. But of course, since I can’t receive texts, entering my phone number does nothing because I can’t receive the stupid verification code.
