Sizing a plan is arithmetic, not mystery. Here are the working numbers — stated as the assumptions they are — and how to apply them to your household or office.
Typical figures, not promises: browsing and messaging are light, well under 1 GB per hour; video calls run roughly 0.5–1 GB per hour; HD streaming roughly 3 GB per hour. Your habits are the variable that matters.
Two people streaming two hours nightly is roughly 360 GB a month on the streaming alone — comfortably inside 1TB once browsing, calls and updates join in, and tight inside 500GB. That single comparison decides most homes.
Twenty staff on documents, mail and daily video meetings typically lands around 1TB–2TB. Media-heavy work moves you up a tier. The business page maps team sizes to plans honestly.
Passing the allowance never cuts you off — unlimited standard data continues. If it happens monthly, that is the signal to move up a plan, and we will say so rather than let you ration.
