How to save on internet and mobile without buying less than you need

Audit lines, data, speed, contract commitments and included services to compare telecom offers with your household’s actual usage.

Internet and mobile bill beside the lines, data and speed used by the household

A cheaper plan is not a saving if it makes an important need harder to meet; a plan with many extras does not offer value if you do not use them. The comparison should begin with the real use of every line and connection in the household.

Audit what you have contracted and what you use

Gather several bills and note lines, data, calls, speed, television, financed devices, additional services, discounts and the end date. Check your actual consumption and ask what will happen to the price when the promotion ends.

The CNMC provides quality information and a speed test. Measure at different times and in different places before paying for more speed or switching to an offer that may not cover your area.

Compare the complete cost

Calculate the price during the first year and after the promotion. Include installation, router, devices, penalties and services that would continue separately. If the package includes platforms, assess whether it replaces payments you already make or simply duplicates them.

  • Remove unused lines and extras.
  • Set data allowances with a reasonable margin above your usual consumption.
  • Review any minimum-term commitment and outstanding financing.
  • Keep the offer and confirmation of the change.

Check the first bills

After switching, check the activation, discounts, return of equipment and closure with the previous operator. Do not judge the new plan based on just one month if it includes prorated charges, but raise any incorrect charge promptly through official channels.

Kinset can identify increases and recurring services in bills, making comparison easier before and after a change. Quality, coverage and terms should be verified with the operator and official tools.

Turn everyday data into a useful picture.

If you would rather not organise receipts, bills, and statements by hand, Kinset can process them and help compare months, categories, and people in your household.
