No, the RPI + 3.9% price increase is built into both Virgin Mobile and O2 mobile terms, and doesn't trigger a Right To Cancel.

Also just for clarity Volt SIMs aren't on the Vodafone radio network, they're O2 SIMs on the O2 network. It's standalone Virgin Mobile SIMs and those part of the Oomph bundles that were on the EE radio network and are being moved to the Vodafone radio network.

Although you get Volt benefits on your O2 SIM, the rest of the terms are standard O2 Pay Monthly terms. So if you are having any coverage issues with your O2 SIM in a Volt bundle, then you'll need to speak to O2 customers services as to what options are available.
