On calls no one can hear me and say I sound like a dalek, every day.

I have this exact same problem. Pretty much every call. I have changed phones x 3 thinking it was the phones and its across my 2 different ee sims.  I have reported in the past but just dont have time to keep calling. All they do is go through settlings and make sure I have wifi calling on then say well there is no problems in the area.  Given online I can see lots of people saying this there is clearly an issue and its been for over 6 months so im now at thw point at looking at cancelling my contract as there is no point having a work phone I cant keep a full call on.  Come on EE sort this out !

A few bits in here.

There is an option on the online status tool - https://ee.co.uk/help/mobile-coverage-checker (follow "check service status") - to report in-call audio problems. That said, I'd be sceptical this is necessarily a coverage issue.

My personal experience of dalek-audio is that it's sometimes related to being edge-of-coverage. In your case I suspect a good test would be to establish whether your phone is using WiFi-calling or the mobile network (VoLTE/4G-calling) when this happens.

Are you using Android or Apple? And if Android - which version? The method for checking this does differ.

If you're insistent with EE-CS when you're reporting this, they do have a technical escalation process to follow - but it may require dated & timed examples of poor calls, and some persistence. Any hint from you, that you'll accept their advice of "no problems in the area", and I suspect they'll be willing to close the call without following that process.
