HD Voice improves the quality of calls made on our 3G network. It reduces background noise and enhances voice reception to make it easier to hear and be heard on calls.
To use HD Voice, both people on the call will need:
- A compatible mobile phone
- To be on the Vodafone 3G network
You will then automatically switch to HD Voice. Calls are charged at your normal rate.
HD Voice is not currently supported on Sure Signal and in-building coverage solutions.
