Really? Doesn’t iMessage fall back to sms if the receiver doesn’t ack? At least that’s what the UX feels like.

- JoblessWonder 3y agoNot OP, but I believe it falls back to SMS if there isn’t a response from Apple’s servers, not the end user’s device. In this scenario the iMessages are sitting there waiting for a registered device to check in to send them to. (Same thing that happens if your battery dies. iMessages go into a void until some place to deliver it to.)
- kelnos 3y agoI think that's if iMessage can't reach Apple's servers. Otherwise that wouldn't make sense; simply being without a cell/wifi signal, or having your phone off, for a few hours, would mean anyone messaging you would be sending a bunch of SMS fallback messages.
- msh 3y agoIt is how it works, after a certain timeout where it can't be delivered to a device it will fallback to SMS. The exact length of the timeout is not public. See https://discussions.apple.com/thread/8063349?sortBy=best https://discussions.apple.com/thread/8063349?sortBy=best
- Volundr 3y agoI have no idea if this is true or not, but I'll note that isn't Apple saying that. It's a random user on an Apple forum.
- sn0wf1re 3y agoYes it does fallback. There are two situations where it does so 1. The sender cannot connect to the imessage server 2. The receiver does not connect to the imessage server, on any of the devices registered to receive at that particular address. I know both methods happen since I didn't used to have data and I would receive SMSs when someone sent me an imessage and I was out and about.
