Messages not being delivered to Blue-Bubble friends? Check cellular data

Here is a delicate situation that recently upset one of our clients. The texts they sent in messages via iMessage (indicated by blue bubbles) to their son, letting him know they were stopping were not delivered, making their visits a surprise. But other texts have worked well. The problem, it turned out, was that cellular data had sort of been turned off in Settings> Cellular. So the messages worked fine as long as the iPhone was on Wi-Fi at home, but as soon as they were on the road using a cellular connection, the iPhone could no longer communicate with the Internet. In theory, messages should fall back to SMS (indicated by green bubbles), which don’t require cellular data, but this doesn’t always happen. The fix? Just turn on Settings> Cellular> Cellular Data again.
