Reader question · before any contract

Will it actually work at my house?

Coverage maps are weather forecasts, not promises. Five steps stand between you and two years of one-bar regret.

5 steps · 2 checkers + trial SIM · weight on indoor readings · re-run yearly

How do I check properly?

Short answer: Two checkers, then a cheap trial month. Trust the trial.
  1. The network's own checker

    Full postcode; read indoor and outdoor as two separate verdicts. Joining a small brand? Check its landlord — the MVNO page says who that is.

  2. Ofcom's checker

    The regulator marks all four to one standard — the antidote to marketing optimism.

  3. Trust the indoor reading most

    Foil insulation and modern glazing eat signal; regret lives in back bedrooms. Judge the rooms you actually live in.

  4. The trial month

    A cheap rolling SIM on the same masts, carried for a month through home, commute and work. The only evidence with no agenda.

  5. Wi-Fi Calling on, whoever wins

    Free, permanent reinforcement for indoor weak spots on any network — signal fixes.

How should I read the maps?

  • Judge the layer you'll actually live on — 4G-only at your address makes distant 5G claims irrelevant.
  • Read "variable indoors" pessimistically.
  • Re-run the check yearly: mast estates never stop changing.

Want a human, not a webpage?

Ring or WhatsApp and ask your question out loud — coverage, switching, a deal you're not sure about, a bill that stalled, a call that smelt fishy. We'll talk it through in plain English.

Calls: standard landline rate (020), usually inside your inclusive minutes. WhatsApp: free on your data. We give general guidance only — we can't open or touch any network account, and we NEVER ask for passwords, one-time codes, banking or card details.
