on the iphone, you just sign out of imessage. go to settings, messages, send and recieve. tap on your apple id and tap sign out. Then apple will know to send any texts to your number as SMS not imessage.
Signing out doesn't solve the problem, because individual phones cache iMessage numbers for months.
Signing out will prevent new contacts from iMessaging you. But it won't remove your number from the persistent cache in your existing contacts' phones. They will continue to iMessage you, no matter that you've signed out.
