Run out of options, any advice?

[Tolkienista]

My Motorola g31 phone is still under guarantee so I've been able to eliminate it from the ongoing problem I've had since June this year.

Making and receiving phone calls from home is an ongoing issue. Not for everyone, but you never know when the call will suddenly end or the person I'm speaking to will say....."can't hear you"

I've been into O2 stores multiple times, new SIM card, lots of settings changed. 

My phone was sent back to the manufacturer last week. Came back with a replacement main board, software update and a factory reset.

The very first call I received when I got home was the familiar refrain, twenty seconds in....."can't hear you"

What did I do now?

Sorry, the final line should read ......what do I do now?

If the issue is just at home, use wifi calling.

If this issue is only occurring in one specific location, then 2 things.

1: It's most likely network-related, potentially affecting a single sector or single site.

2: WiFi-calling is a good workaround.

Yep

Thanks for your message. 

Wi-fi calling is enabled on my phone.

Thanks for your message.

As I've just said, wi-fi calling is enabled on my phone. So that's not an option for me to suddenly activate.

[Tolkienista]

At the moment i can't accept a solution as WiFi calling is already enabled on my phone.

@Tolkienista 

It might be that your phone is not using wifi calling if you always get the same issue.

Check the phone settings to ensure that the wifi calling is set to wifi preferred.

Are you on PAYG or a monthly contract @Tolkienista ? 

I don't think WiFi calling is available on O2 PAYG ; although you can turn it on via your handset's setting so that it looks like it is on ! 👍
