A little more budget or a different network could open things up.

Prices and availability can change. Check the network provider's final terms before ordering. First-year estimates include known price rises and introductory periods; conditional cashback is shown separately.
Our O2 listings can include different contract lengths and sellers. Compare the regular bill first, then examine any gift or cashback conditions. A claim-based reward should not be treated as an automatic reduction in the amount leaving your bank account each month.
If an offer mentions a bundle or existing-customer benefit, check the qualifying services and account requirements. Do not assume a new-customer promotion applies to an upgrade. For travel, check the destination and fair-use rules of the selected plan before relying on an included roaming label.
An introductory discount can make the first few bills smaller. We show when that price ends and the ongoing price beside it. The first-year estimate adds up the known payments, rather than multiplying a temporary offer by twelve.
You can normally keep your number when switching network providers. Request a PAC from your current provider and give it to the new one. Check your existing contract for any early exit charges first.
Some network providers use another operator's mobile network. Coverage may be similar, but speeds, roaming, extras and customer service can differ. Compare the plan itself, not just the network name.
Not exactly. Twelve 30-day renewals cover 360 days. Where the offer explicitly uses this billing cycle, we label that estimate separately. Always check the provider's billing and cancellation terms.
