Can I rely on mobile broadband in Castle Point?

Outdoor 5G reaches 100% of Castle Point homes. Here is how mobile holds up if the line drops.

4G indoor coverage

5G availability

outdoor 5G from at least one network
Next-gen 5G

standalone 5G, lower latency
No 4G indoors
<0.1%
no 4G signal at all indoors

The two 5G figures differ. “5G availability” is everyday 5G running on the existing 4G core, which is what most phones show. “Next-gen 5G” is standalone 5G: a full 5G network with lower lag, still reaching fewer places.

Indoor 4G is near-universal in Castle Point and outdoor 5G is widespread, making mobile a strong backup for fixed broadband and a viable primary connection via a 5G home-broadband hub.
