Who else does not receive text message from android users?

Who else does not receive text message from android users?  
I Switches my service from Verizon Wireless to Xfinity mobile with my iPhone 12 max pro, and I’m unable to receive any text messages from any android users or authentication text messages. I’ve been on the phone with Xfinity mobile for over six hours today. It’s been very frustrating. Does anybody have a solution?

This was escalated to Engineering, they told me it will be fixed within 72 hours. I am holding my breath. Seeing this has been an issue for years and the regular techs no nothing about is mind boggling.
