Mobile data connection drops when on call.

Tominator — Thu, 01 Aug 2024 15:52:55 GMT

Hi all,

I have a Pixel 8 Pro (although this also happened on my previous device - Redmi Note 10 Pro) and I am finding that most of the time, as soon as I begin a voice call, the mobile data 5G/4G/3G, will drop to 'H' but will simply not pass any data.

This is really frustrating, especially if I am out of WiFi range and am having to use my mobile as a Hotspot and talk to a customer on the phone at the same time.

There are occasions when it will retain the 5G/4G/3G connection, but more often than not, it won't.

I have tried disabling WiFi Calling at network level, and also rebooting my device, but neither help.

This also happens wherever I am geographically. so I don't think it is down to service on a particular mast.

Any information that help would be much appreciated, as at the moment it is making life very difficult and I am seriously considering moving networks.

Many thanks in advance!

Tom.

And try setting up the O2 MyNetwork app to monitor for you, it uses a separate credential from the forum here and from your MyO2:

Good luck, @Tominator

Standard issue with O2 ever since I can remember @Tominator so unlikely to change anytime soon.

I've had this issue starting up over the past few days having never had a problem like this before.

Can anyone help with this?

What's changed, @dm1983?

Nothing has changed at all.

It has literally just started happening.
