Our Methodology
This page explains how DataCost builds comparisons so users can understand what the rankings mean and where limits exist.
Data Sources
We compile published bundle information from operator channels such as official websites, self-service menus, and public plan pages.
Promotional and personalised offers (for example user-specific deals) may vary by account and are not always universally available.
How We Compare Value
Our tables focus on practical comparison metrics such as bundle price, validity period, and estimated cost per GB.
We treat bundle categories separately where possible (for example monthly, 1GB, and night-data) to avoid misleading like-for-unlike comparisons.
Ranking Principles
- Prioritise transparent pricing over marketing labels.
- Use category-specific comparisons rather than a single universal “winner”.
- Highlight known limitations such as coverage context or night-only usage windows.
- Prefer clarity for consumers over network promotional language.
Update Cadence and Corrections
We review key pages on a rolling basis. If pricing changes faster than our refresh cycle, live operator checkout pages take precedence.
Report potential errors through our contact page and we will verify and update where needed.
