I sent a couple of iMessages to another iPhone AFTER that phone was powered off... so the iMessages never delivered and still haven't. If I turn on Airplane mode, will the texts fail to deliver once that iPhone is powered back on?
It will keep waiting for that device to connect and the moment it does, at any time during that 30 day period once the message has been sent, it will deliver all messages sent to that device and sitting in the queue.
At this point, the status of your phone has nothing to do with it - the minute you hit send when you were connected to the internet, it was uploaded to Apple's iMessage system. Now, it is purely a matter of the recipient device connecting to the internet at some point within 30 days of you sending it. When it does, any and all undelivered messages sent to it within the past 30 days will be delivered.
But once you hit send, and the message is sent off to Apple's servers, your device can be vaporized and it won't affect the delivery of that message at all.
Once you click send, the messages are transmitted to Apple's iMessage servers and cached there. The iMessage system will repeatedly try to deliver them for up to 30 days. It will purge the messages once delivered, or after the 30 day delivery attempt period has passed.
If I turn on Airplane mode, will the texts fail to deliver once that iPhone is powered back on?
I don't think so. The messages have been sent to the Apple server but not yet delivered
When you say repeatedly try... does that mean it will succeed regardless when my airplane mode is on and their phone is back on?
Thank you!
Airplane mode after sending text to an off iPhone?
