A simple trick but it sometimes works.

Turn your device off, wait ten seconds, then turn it on again.

Always worth a try.

What affects signal strength?

Indoor coverage is much harder to predict than outdoor coverage.

Unfortunately, no network can tell you exactly how strong your signal will be indoors. This is because the signal strength needed to pass through walls and windows varies from building to building.

But the great news is we're rolling out 4G Super-Voice, our super-pumped new signal that travels much deeper inside buildings - so no more indoor blackspots.

And for extra peace of mind, there's Three inTouch - our free app that lets you call and text over Wi-Fi, even when there's no mobile signal.

Extreme weather.
Strong winds, flooding or falling trees for example can affect our masts.

Extreme weather

Distance from mast.
The closer you are, the stronger your signal.

Issues with your device.
Some devices are better than others at picking up a signal. Your settings, the SIM, a low battery, and running older software can also affect the signal.

Issues with your device

Temporary structures.
Cranes, for example, can obstruct the signal.

Temporary structures

Building materials & location.
Signal can be affected by a building's location - if it's in a valley or behind a tree, for example - as well as the materials used to construct it.
