Probably just a matter of time before it does. I get that it is a large undertaking on their part to get this fixed but reading the article, this issue has been known since 2011 so knowing that it's sad on Apple's part that they haven't figured this out. On another website the poster stated that the Apple rep had little sympathy and told him to just get a new number from his carrier; that is the lamest excuse I've heard. There are so many accounts associated with your phone number these days that it's impossible to remember them all and make the necessary changes. Others saying I should have known to log out of iMessage and all that other stuff... sorry I guess I didn't get the memo from Apple regarding this being an issue, besides I've never had to worry about anything in the past when switching phones. I just hope they somehow get this issue figured out because they are causing some major headaches for folks. Im pretty much done with Apple after this experience (may sound extreme but its been a bad enough experience for me) and I doubt Im the only one.
The point is that the originating iOS device would know at that point that the recipient is no longer compatible with iMessage and simply use SMS as it would with any recipient that never supported iMessage.There is a major secondary issue when changing from an iPhone to a DROID (or non-iPhone). Even after you get your iMessage Registration revoked you still cant receive SMS from any iPhone that previously sent you iMessages if the originating iPhone has the option Send as SMS set to the default, OFF. The workaround is to have the originating iPhones set the Send as SMS option to ON which isnt a great solution if you have dozens or hundreds of Contacts with iPhones.
The main issue here is that in many cases the message gets sent as iMessage still (even though it should no longer be as the recipient no longer has an iOS device) and it never actually gets registered as failing, it just gets sent as iMessage and that's it. So that Send as SMS setting wouldn't make a difference in cases like that. And, ultimately, the underlying issue is still unrelated to that anyway, it's that Apple shouldn't try to send an iMessage to someone who no longer supports it, no matter what the settings on any one's iOS device might be.Yes, that is what is supposed to happen. With iOS 7 Apple changed the default for SEND_AS_SMS to OFF instead of ON. With SEND_AS_SMS = OFF the originating iPhone knows that the message did not deliver via iMessaging - actually displays NOT DELIVERED in red letters - but is unable to then send as a SMS.
