Please troubleshoot using the following methods:
- Check that your device isn't set to silent mode
- Check that your volume isn't turned down
- Check that the sound isn't coming through devices such as headphones
Note: If the word "headphones" is displayed or a headphone icon appears when adjusting the volume, there is a possibility that headphones are connected. Please disconnect the headphones and see if this solves the issue.
These methods may vary depending on the device you’re using. Please contact your device's support service or your mobile network provider if you have any questions regarding your specific device.
