The question everyone asks is whether a plan will work at their address, and it is the one question no provider answers with a yes. That is not evasion. It is a structural limit on what any coverage map can honestly claim.
What the maps actually predict
The published wording is precise: check the provider coverage map to see what network coverage is predicted where you intend to use the service. Predicted. The map is a model built from tower locations, terrain, antenna patterns and historical measurements, and every one of those inputs is an estimate at the scale of an individual building.
The things that make a prediction wrong
- Building materials, which matter far more at 700MHz than people expect.
- Indoor position: a basement room and a top-floor apartment on the same street can differ by several bars.
- Terrain and distance, which the provider includes but which resolve to a radius rather than a wall.
- Tower upgrades and new sites, which make any map a snapshot.
- Device band support, which can void the prediction entirely.
What to do instead of asking for a guarantee
Take the addresses that matter and check them on the map of the network you are actually buying, not the brand. If a result is marginal, the cheapest way to find out is a cheap SIM on that network, not a long-term plan. And if coverage is the deciding factor, we would rather tell you the plan is a poor fit than sell you a headline.
Coverage. No provider promises coverage street by street, and neither do we. Check the provider coverage map for the addresses you actually care about before you commit to a plan.
