The true-cost calculator
Contract or separate phone and SIM? Compare both, including upfront costs and price changes.
Compare total costs ↗Your plan, your priorities
Set your budget, data allowance and contract preferences. See only verified, eligible offers.
Find a plan ↗How much data is enough?
Turn your everyday habits into a useful estimate, so you can choose a sensible allowance.
Estimate my data ↗The monthly price
is only half the story.
Upfront payments, annual increases and a longer term can change the real cost. We put those numbers in one place.
See how it works ↗Keep your phone, upgrade it, or simply check your bill.
Compare the same period, with costs and known changes included.
Coverage, roaming and provider terms matter as much as price.
A little more before you decide.
Is a SIM-only plan always cheaper?
No. It depends on the handset price, plan price, upfront payment and any increases. Our calculator compares both options over the same period.
Do you list every UK mobile plan?
No. We compare selected verified options. The catalogue currently has no live offers while approved partner access is being arranged. You can still use both calculators.
