Coverage maps are weather forecasts, not promises. Five scouting steps before you sign anything.
cenioklo is an independent info site. Zero connection to Three, O2, Sky, EE, Vodafone or anyone else — their names only mark what a page is about. We never take payments, never see accounts, never ask for codes or card details. For anything about your bill or contract, your network's official line (printed on your bill) is the right call. Ours (020 3996 8779, standard landline rate) is for general guidance only.
Full postcode; read indoor and outdoor as two separate answers. Budget brand? Scout the HOST — who rides whom.
The regulator grades all four networks by one honest standard — the antidote to marketing optimism.
Foil insulation and modern glazing eat signal; regret lives in back bedrooms. Judge by the rooms you actually use.
Cheap SIM on the same masts, lived with for a month — home, commute, work. The only evidence that never lies.
Free permanent backup for indoor weak spots, whoever you pick — signal mission.
Ring us to talk through switching, coverage, complaints or anything on this site. We can't open accounts, take payments or speak for any network — but we can make it all make sense.
