Had my number ported over today from O2 to Virgin, call quality is horrendous! My customers tell me it sounds as if I have a box over my head and standing away from the phone. Also, there’s a delay in them hearing me. My side is just as bad, I can barely hear the caller as it is so muffled.
I called 789 from my phone and they told me to reset network settings and enable VoLTE. I did this but nothing has changed, even with Wi-Fi calling enabled.
I notice my phone is on 4G but as soon as I make or receive a call it drops to 3G, even though 4G is selected in my settings.
How can this be rectified as it’s impossible to work like this? Up until my number was ported I have never had an issue.
