Mobile Data Is Not Available During This Call

Recently I've started receiving an error stating "Mobile Data Is Not Available During This Call".

However ever since upgrading my tariff to an All-rounder tariff back in October I've found that my signal and data speeds seem to have decreased and gotten worse. Along with upgrading my tariff I also upgraded from an iPhone 14 Pro Max to an iPhone 17 Pro Max.

Is there any setting or anything I may need to change to get the full potential from my phone?

I just seem to think it's weird that I get a worse mobile service on an All-Rounder plan than I did on the capped Essentials plan.

 

Cheers!

HI @Patty37 

To fix "Mobile Data Is Not Available During This Call" on an iPhone, ensure VoLTE is enabled by going to Settings > Cellular > Cellular Data Options > Voice & Data and selecting VoLTE to on. 

Then restart your device.  

If you still have a problem, does this only happen in your home area or in other areas/towns too? 
If its only in one area, you can you can check coverage and network status at Check mobile coverage where you can also report any issues you are facing.
