Compare mobile package and broadband usage fit in one place with provider filtering, package recommendations, and estimated monthly internet cost.
Quick planning, rough comparisons, and checking whether your assumptions are in the right range before you rely on final quotes or advice.
Review the assumptions below, then compare with related calculators if your decision depends on rates, eligibility, or provider-specific rules.
How this calculator works
- Choose whether you are checking a mobile package or a home broadband connection.
- Enter your expected monthly data usage, budget, and either call minutes or number of users.
- The page ranks indicative package profiles by fit score, estimated top-up pressure, and monthly cost.
Worked example
If you expect 30 GB of mobile data, around 250 call minutes, and a budget near LKR 2,000, the tool ranks the closest mobile package profiles first.
Important assumptions
- This page uses indicative package profiles inspired by package-comparison workflows rather than live provider APIs.
- If a package does not fully cover your usage, the calculator estimates top-up pressure using simple extra-cost assumptions.
- Broadband usage is treated as shared household usage when you enter more than one user.
- Always verify the final package name, tax treatment, and fair-use terms on the provider website before purchase.

How this calculation is produced
- This calculator uses the formula and assumptions defined for the page to turn your inputs into a practical planning estimate.
- Results are designed to be quick, transparent, and useful for first-pass decisions rather than provider-specific final quotes.
- The output should be treated as a directional estimate until you check the relevant rates, rules, or assumptions behind your case.
What to verify before relying on it
- Check that your units, assumptions, and scenario match the real decision you are trying to make.
- Compare the output with a second trusted source if the result affects money, health, or compliance.
- Use official provider, government, or expert information whenever the estimate needs to become a final decision.
When this tool is useful
- Use this for quick planning, early comparisons, and first-pass estimates.
- Use it when you need a decision baseline before opening a spreadsheet or asking for quotes.
- Use it again whenever the main assumptions behind the calculation change.
How to read the result
- Treat the primary result as an estimate that depends on the inputs and formula assumptions.
- Compare supporting metrics, not just the headline number, before making a decision.
- If the output affects spending or health decisions, validate it with a second source.
Common mistakes
- Entering optimistic assumptions and reading the result as certain.
- Comparing results from different tools without aligning units or definitions.
- Using one scenario only instead of testing a few realistic alternatives.
Good next steps
- Run a second scenario with stricter assumptions.
- Compare the output with related calculators or guide pages in the same topic.
- Use the result to narrow options, then confirm details with real provider or expert information.
