Mission: understand data

Before you read on 🦊

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.

Where 'unlimited' bends

1. Tethering

   Hotspotting laptops is the clause networks police — some plan generations cap it even on unlimited tariffs. Heavy hotspot user? Read this clause before signing anywhere.

2. Slow-down rules

   At a rammed mast, extreme users can be deprioritised so everyone else survives. Normal players never notice.

3. The border

   No plan is unlimited abroad — fair-use ceilings always apply. Roaming mission.

Stop overpaying for infinity

• Check three months of real usage in your network app before buying unlimited — most people use far less than they think.
• Bank mechanics: Sky's Roll makes a modest plan grow over time — how it works.
• Unless unlimited is cheap: Three usually prices it lowest of the big four — cheap infinity beats careful arithmetic.
