Iphone6 is plugged in, and the text message can't be heard.

Please refer to the answers of netizens.

Look at the call first. If there is sound, you are in headset mode.

The solution is as follows

1 Settings-General-Accessibility-Call in sports activities (default)

2 Use the earphone connection interface of iphone, turn on the ipod to listen to music, then press Pause, press home button to return, turn off iphone (without using other third-party software), unplug the earphone and turn it on again. If it doesn't work, it won't work after several attempts. Press and hold power home for hard restart, and unplug the earphone when a white apple appears.

We can simulate listening to music, but this time, don't pull out the earphone too fast, but rotate it gently. Sometimes it is pulled too fast, and the program of the mobile phone doesn't respond. So always keep the headset mode.

When the phone is turned off, we unplug the earphone, find a needle and gently poke it into the earphone hole twice. It may be that the bouncing device inside did not return to its original position after the earphone was unplugged. After poking, we wrapped the toilet paper with a needle, wiped the inner wall of the earphone hole and wiped off the dust covered on it.

If all the above methods fail, we can try to restore the factory settings, but in this step, you should back up the data on your mobile phone.

Not yet. It's just a hardware problem. Send it for repair.
