What we do (and don't do)
- We copy prices and plan terms from each provider's own website and date-stamp them.
- We explain the trade-offs: fixed data vs "unlimited", daily speed caps, hotspot limits.
- We don't publish speed tests or "hands-on" reviews we haven't done, and we don't use fake ratings.
