iPhone 7 calling speaker is not working

[Harvestmoon2019]

None of my calls are going through. The speaker option for calls does not even work.

I am able to hear music from the sound speakers.

Hey @Harvestmoon2019, 

I'm sad to see you're having trouble with this service. Can you tell me if you're also experiencing difficulties when you receive calls? Can people hear you when you're speaking through the phone?

Just to confirm, your other services such as text messages and data are working fine?Also, have you tried rebooting the device to see if you notice any improvements for the speaker?
