Vodafone *do* let you use the internet and make calls at the same time.

All networks do.

You can, although it varies by handset.
I should probably point out (though this is less true now than it was last decade) that many phones have limitations in their data + voice capacity. Particularly handsets rated at 7.2Mbps and below will suffer big drops in data speed while on a call, or may also lose access to higher speed technologies (e.g. HSxPA) falling back to 384Kbps or worse. This is a technical limitation of many handsets - though again, more recent phones are unaffected.
Similarly, on the network side, the base station may not be able to allocate you to all the fastest channels while on a call, again a technical limitation, causing the device to fall back to legacy modes. Problem is most networks these days are not designed around using these legacy modes as their primary data bearer, often they are only kept for compatibility and have very limited capacity.
Or it could just be a bug in the handset or base station.
