Question: Text messages sent whilst phone is off are disappearing
I turn my iPhone off around 11pm each day. When phone is turned on the next morning any text messages sent during that time are shown initially on the text message icon with a 1,2 etc. However as soon as phone automatically flicks from 4G to wifi they disappear and are then never received.
I know they have been sent as friends have shown me screen shots of what was sent.
iPhone 6, iOS 11.2.6
