What 'unlimited' includes, the three published conditions that qualify it, what actually consumes an allowance, and how much data an ordinary household really uses.
Written July 2026 · no prices published · nothing for sale
On the handset, at home, yes — genuinely unmetered on all four mast owners. Three published conditions bend it, and each is readable before you sign.
| Condition | What it does in practice |
|---|---|
| Tethering cap | Limits sharing data with a laptop on some plan generations |
| Traffic management | Queues extreme outliers at saturated masts; normal heavy use never notices |
| Fair use abroad | Ends the unlimited part at a published figure, then charges per gigabyte |
The tethering clause is the one that catches people, because it is the one that matters if you work away from a desk. Read it on your exact tier rather than on the marketing page.
| Activity | How hungry it is |
|---|---|
| Video at high quality | By far the biggest consumer on most accounts |
| Cloud photo and file backup | Large, invisible, and easily moved to home Wi-Fi |
| App and system updates | Heavy in bursts; restrict them to Wi-Fi |
| Social feeds with autoplay video | Substantial, and autoplay can be switched off |
| Messaging, email, maps, music | Comparatively tiny |
Far less than most people buy. Rather than guessing — or letting somebody in a shop guess for you — open your app and read three months of recorded usage. That captures holidays, unusual weeks and everything else.
Buy that measured figure with a little headroom, and handle any unusual month with a one-off add-on rather than a permanent tier increase.
