Signal in a nutshell.
As the network built for the internet, we know that signal and speed are hugely important to the experience of our customers. The more coverage bars on your phone or on your Mobile Broadband dashboard, the stronger your signal. This of course means faster, more reliable internet access, calls that are less likely to cut out, and overall better call quality.
What affects your signal.
The speed you get can be affected by a number of factors, including how many other people are using the Three mast that you're connected to (masts are what we use to carry data, calls and texts on our network). The closer you are to one, the better the reception you’re going to get. Other factors like extreme weather conditions such as snow or temporary structures like cranes and thick walls, can also have a bearing on the quality of your signal.
We’re improving signal strength and internet speeds.
Our network improvements have been focused on building more masts and improving the range of these masts. This means that more of our customers in more places have better coverage when calling, texting and using the mobile internet with Three.
So when we start rolling out 4G, we'll nudge up all our customers who have a 4G Ready device at no extra cost.
Until then, our 3G network already covers more than 98% of the population – and over 80% of them can enjoy a fast internet experience on our Advanced 3G network using their Advanced 3G Ready devices.
If you're interested in the numbers, you can find out more about the speeds you can expect on our network here.
You can also report a problem with the network online. Use our coverage checker tool to check indoor and outdoor network coverage near you, or tweet @ThreeUKSupport to ask us about issues and maintenance that might be affecting you.
