If you’re having trouble getting your iPhone to play text message sounds when it’s locked, there are a few things you can try. The first is to make sure that your ringer switch is in the "on" position. You can also check to see if your sound effects are muted by checking the "Mute" switch on the side of your phone. If your phone is in silent mode, the sounds for text messages and other notifications will also be muted.
