If Android phone not receiving text messages from iPhones, a typical solution is if the Android phone’s number was previously linked to iMessage. If that’s not the case, then you’ll need to dig deeper into the issues.
Android not receiving texts after switching from iPhone
When you stop receiving text messages from your iPhone-using friends, family, and coworkers, it's usually due to connectivity issues or a problem with iMessage. If you can receive text messages from Android users and it's only iPhones that you can't receive texts from, then the culprit is usually iMessage.
If you are not receiving text messages from iPhones on your Android, try these solutions:
Remove your phone number from iMessage. If you've switched from iPhone to Android, you can no longer receive text messages from iPhones until you deactivate your phone number from iMessage. When iPhone users send a text message to a number that's still in the iMessage system, the text message goes to iMessage and can't be delivered to the Android phone. If you still have your iPhone: Open Settings > Messages and tap the iMessage slider to turn it off. Then tap the Back button > FaceTime and tap the FaceTime slider to turn that off as well. If you no longer have your iPhone: Visit Apple's Deregister iMessage website , enter your phone number, and then enter a code sent to you via text message.
