No data while on call

[vincepettit]

Previously while on calls I have been able to use data, but recently it seems this isn't the case, which is causing issues when on calls when commuting with things like Waze not updating.

I am currently using a iPhone 15 Pro, is there a setting that I'm missing or is this just how Vodafone works now?

I don't know if it helps anyone else, but I just switched back to Vodafone with my Google Pixel 6 pro and found this issue. After finding this chat, particularly the comment before this, I found that there was a setting under Settings > Networks and Internet > SIMs > Vodafone called 'Allow 2G'. I turned that off and I can now use data whilst on calls!
