Most 'my network is rubbish' moments are one room, one wall, one setting. Run this combo before blaming anyone.
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.
iPhone: Settings → Mobile Data → Wi-Fi Calling. Android: Settings → Connections/Network → Wi-Fi Calling (names vary). Calls now ride your broadband, normal number. Toggle missing? Your provider may need to enable it — or may not support it on your brand. Confirm officially.
3G is switched off across the networks — calls need the 4G layer. Some phones shipped with it off.
Airplane mode on → count ten → off. Forces the strongest local mast. Clears a silly share of "stuck on one bar".
Carrier-settings updates carry real network fixes.
Window beats inner wall; upstairs beats basement. Insulation and glazing are the real villains.
Postcode into the network's status checker — planned mast work explains most sudden outages in ten seconds.
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.
