FAQs

Virgin Media and O2 joined forces in June 2021, creating one of the nation’s largest telecoms providers – offering award-winning mobile services and lightning-fast broadband in one place.

In January 2023, we announced that Virgin Mobile customers would be moving to O2 plans by the end of the year, and that we’d be simplifying our mobile offering under the O2 and giffgaff brands.

We stopped trading as Virgin Mobile at the end of August.

Don’t worry – Virgin Media services like broadband, TV and home phone aren’t changing at all. 

With any O2 plan, you can roam freely – using up to 25GB of data – in the EU and four more countries, making up 47 countries in total. All at no additional cost.

So, you can stay connected without worrying about extra charges while you’re travelling.
