Four companies own the masts and everybody else rents from them — the single fact that explains most of the confusion in British mobile.

| Owner | Where it came from |
|---|---|
| EE | Built in 2010 by merging Orange and T-Mobile; launched Britain's first 4G in 2012; owned by BT Group |
| O2 | Began as BT Cellnet; renamed in 2002; half of Virgin Media O2 since 2021 |
| Three | Opened in 2003 as the data-first newcomer; half of VodafoneThree since June 2025 |
| Vodafone | Among the oldest in the market; the other half of that 2025 merger |
Companies without masts buy capacity wholesale and resell identical radio waves under their own name. That is the entire arrangement, and understanding it removes most of the confusion in this market.

Coverage questions belong to whoever owns the masts. Complaints belong to whoever sends the bill. Getting those two the wrong way round wastes an enormous amount of people's time.
June 2025 combined two of the four owners into the largest operator in Britain by customer numbers, with substantial money committed to merging the two mast estates.
For customers the practical consequence is that coverage at any given address is less settled than usual. An address that failed a year ago may pass now — which makes an annual re-check genuinely worth doing.
