The supermarket network that keeps topping happiness surveys — O2's signal, simple plans, and controls parents actually use.
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.
Rides on O2's masts. Everything that actually matters:
The mast decides — coverage mission on O2's hub.
PAC to 65075 — free, 30 days. Switch mission.
Tesco Mobile's own support first; 8 weeks stuck = free ombudsman. Your rights.
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.
