What a coverage percentage doesn't tell you
That figure is about people, not land — it's predicting outdoor signal for that share of the population, not blanketing that much of the map.
Where the 2026 scores landed
EE leads at 920/1,000. Vodafone follows at 808/1,000. Three sits third at 799/1,000. The combined VMO2 figure comes in at 768/1,000, though it picked up Europe's biggest year-on-year improvement last year.
O2's satellite addition
O2 switched on direct-to-mobile satellite coverage in 2026 — the first UK network to do so — pushing effective landmass coverage from 89% up to 95%. That extra layer doesn't reach Tesco Mobile or Sky Mobile customers, even though both run on O2's masts.
Where the piggyback networks land
Tesco Mobile and Sky Mobile inherit O2's signal exactly. iD Mobile inherits Three's. None show up separately in independent tables, since none run their own towers.
Checking your own postcode
Every network publishes a coverage checker — worth using before you commit, whichever one you're considering.
A quick note on who we are: neylscout (neylscout.online) is run by independent researchers, not by any mobile network. We write about Three, O2, EE, Tesco Mobile, Vodafone, Sky Mobile, and iD Mobile because people ask us about them — none of these companies sponsor us, pay us, or have any say in what we publish. We are not a reseller and we never sell airtime, SIMs, or contracts through this site, and you won't find a single price on these pages, because prices move too often for us to keep accurate. If you ring the number on this site or fill in our form, you'll reach our own small team — never a network's official support desk, and never anyone able to touch your account. Every brand name and logo colour you see here belongs to the company it names; we use them only so you can tell which network a page is about, not to suggest any partnership. Treat everything here as a starting point for your own research, and check the final word with the network directly before you commit to anything.
