Why doesn't imessage automatically switch to sms
When another person's iphone recognizes that the receiver's phone is currently not connected to wifi, and therefore can't receive an imessage, why doesn't the person's phone automatically sends the text as a sms instead of an imessage. The way the current system works is that if you have a conversation with someone through imessage, and suddenly, you have to turn off wifi, you will not receive any of the other person's texts until you turn on wifi again.
