Calculate total contract cost
Multiply each monthly charge by the months it applies, add the upfront payment and include any clearly stated changes. Keep device finance and airtime separate when the agreement presents them separately.
- Upfront payment
- Monthly charges across the term
- Stated price changes
- Trade-in or cashback conditions
Build the SIM-only alternative
Add the outright handset price to a SIM-only plan that provides enough data and the required roaming or calling features. Use the same comparison period as the bundled contract.
Test coverage where it matters
Coverage maps are a starting point. Consider home, work and regular travel, indoor reception and whether Wi-Fi calling is supported by the network and handset combination.
Avoid paying for unused allowances
Check recent data use before selecting a plan. Unlimited data can be valuable for some households, but it should not hide a more expensive handset or a needlessly long commitment.
Read the promotional conditions
Trade-in values can depend on condition, cashback may require claims and roaming terms vary. Confirm ownership, early-exit and return arrangements before completing the order.
