The SIM is now a download on every big UK network. Five minutes to install — plus the one security habit that guards your bank.
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.
Your network's own app, site or shop issues the QR code or in-app setup. Nobody else can legitimately do it.
Most recent flagships support it; hosted brands sometimes lag — check yours.
The free PAC text is unchanged — switch mission.
Your number now guards your bank's security codes. Criminals know.
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.
