[iMore Question]

I downloaded ios 10.2 to my iphone 6 last night. This morning I cannot send text messages. What's the problem? I can type the text message, press send, and message stalls in the "sending" mode and eventually is "Not Delivered". Big problem! I am very annoyed.

Try resetting your Network Settings and see if that makes a difference.

Is the device connected to the internet either via cellular data or Wi-Fi? Are you in an area of spotty Wi-Fi or cellular service? Have you tried contacting your wireless service provider to see whether or not they are experiencing problems with their network?
