If no one can hear you on the other end while on the call may likely be due to some microphone issues with your phone. Check these easy steps first:
- Check that your microphone is not muted, or if there is any background noise, move to a quieter area.
- Try again. Sometimes just redialing is enough, but your phone restart can also help.
- Check if the issue is happening to a specific phone number on outgoing or incoming calls - can the other person hear other callers?
- If possible, connect a compatible wired headphone that has a microphone. If the headphone works, check that your phone's microphone openings are not blocked. To find the microphone openings, see your phone's user guide or search online to find the chapter: ‘Explore the keys and parts of your phone’.
