However, the same thing happened to me when I switched from my pixel 3a to an iPhone. I wasn't able to text from my iPhone for a week. I ended up contacting Verizon and they actually had their network engineers investigating. What they ended up discovering, and sent me a contact number for it, was that some how Google's RCS was still holding a lock on my number or something. So this isn't an exclusive Apple problem.
