Our 5G coverage map meets Ofcom High Confidence standard. However, although these coverage results are accurate, the information is only a guide and doesn't guarantee service availability in a particular location. Coverage may vary depending on your device and whether you're indoors. We are continuously improving our network to ensure our 5G service reaches even more customers.
Unfortunately, no network can tell you how strong your signal will be indoors. That's because the signal strength needed to pass through walls and windows varies from building to building.
Your SIM card, phone settings, a low battery, and running older software can all affect the signal. If your account is on hold, that will also prevent use of the network.
The closer you are to a mast, the stronger your signal. It can also be affected by geographical things, like hills, valleys, forests, etc.
Strong winds, flooding, storms, falling trees, etc. can all affect phone masts.
Cranes or scaffolding, for example, can obstruct the signal.
When we're carrying out planned or unplanned maintenance, your signal will probably be affected.

They're the 3rd, 4th and 5th generations of mobile network. The main difference between them is the speeds they can reach, with each generation hitting faster speeds as they go along. This affects how smooth your online experience is.
Our 5G Business Broadband hub can get you online as soon as tomorrow, all with unlimited data. No landline. No engineer. No waiting. It's broadband, but better.
Location’s usually the main thing that affects coverage – if you’re far away from a mast, your signal will be weaker.
But coverage can also be affected by things like trees, being in a basement or underground, travelling, and even your phone itself. Getting higher up, opening windows, and upgrading your phone can all help improve your signal.
