Virtual (local) networks: who runs on what
Dozens of smaller UK brands rent capacity from the four physical networks. Knowing the host tells you exactly what coverage to expect.

How virtual networks work
A virtual network (MVNO) sells plans under its own brand but carries your calls and data over another operator's masts. You get the host's coverage with the virtual brand's pricing, support and features. Tesco Mobile, for example, has repeatedly topped UK customer-satisfaction surveys while running entirely on O2's infrastructure.
| Virtual network | Typical host | Notable for |
|---|---|---|
| Tesco Mobile | O2 | Consistently high customer satisfaction |
| giffgaff | O2 | Community-support model, no contracts |
| Sky Mobile | O2 | Data Roll piggybank |
| VOXI | Vodafone | Social media data passes |
| Lebara | Vodafone | International calling focus |
| SMARTY | Three | Simple one-month plans |
| iD Mobile | Three | Value-focused plans |
| 1pMobile | EE | Pay-per-use pricing model |
Three rules for choosing a virtual network
- Check the host's coverage, not the brand's adverts. The mast is the host's; the marketing is the brand's.
- Confirm feature support. Wi-Fi Calling, eSIM and 5G access vary by virtual brand even on the same host.
- Know where support lives. Account matters always go through the virtual brand's own official channels, never the host network.
