If you are having trouble getting messages to show up on your iPhone 6, there are a few things you can do. First, try turning off your phone and then back on it. If that doesn’t work, try resetting your phone. If that still doesn’t work, then you may need to unblock the phone’s messaging service. To do this, go to Settings and select General and then Messages. Once there, select the account you want to unblock and then press the Unblock button.
