Virgin Media O2 Issues Warning as Switch Off Could Leave Customers without Internet
Virgin Media O2 began switching off its 3G network across the UK on April 2, 2025, starting in Durham and continuing throughout 2025.
This switch off follows the broader trend of major UK mobile providers gradually retiring 3G services to prioritize faster 4G and 5G networks.
The 3G shutdown by Virgin Media O2, which started in early April, will also impact other carriers that rely on its infrastructure, such as Giffgaff, Sky Mobile, and Tesco Mobile, prompting users with devices limited to 3G to upgrade their phones.
Virgin Media O2 has warned that once the 3G network is discontinued, users might notice poorer call performance and lose the ability to use mobile internet and apps that rely on data, such as WhatsApp.
Customers with older devices or SIM cards unable to connect to 4G/5G will lose mobile data but can still make calls and send texts, while Virgin Media O2 supports vulnerable users through direct outreach.
