Some iphone users texts are not receieved on android phone
I had an iPhone active with my phone number for a day. I switched to Android. Since that time some iPhone users texts don't reach my android phone. I know they are sending as I later see them on my iPad. It's impossible for me to ask every iphone user to text my number and not my Apple ID. How do I fix this? The deregister process says there is no association and I don't have access to the iPhone anymore.
iPad, iPadOS 18
