Few things can be more frustrating than when a message doesn't get stamped with the reassuring "Delivered" label. But you're not helpless — here are the most common ways you can troubleshoot and solve this annoying problem.
If you don’t see the “Not Delivered” error, the recipient’s phone might simply not be receiving messages. In the first case — it simply doesn't say it has been delivered, even after several minutes, keep in mind that the most likely explanation is that the recipient's phone is turned off, in Airplane Mode , or has a poor connection.
iMessage needs access to the internet, either via WiFi or a cellular signal, so if you have no service, a network issue, or are in Airplane Mode, the message can't be sent. Check your WiFi and cell signal to make sure your phone can communicate with the outside world. There might be a glitch with your Messages app or your phone's network connection that turning it off and back on again will solve.
To see if it's disabled on your own phone, start the Settings app and tap Messages, then ensure iMessage is on by swiping the button to the right. Generally, if you see this message when trying to send an iMessage, it means you got the iPhone less than a day ago and all of the phone's services are not yet fully activated.
