Why indoor signal strength varies.

Unfortunately, no network can tell you exactly how strong your signal will be when you're indoors at home, work, or in any other building.

This is because the signal strength needed to pass through walls and windows varies from building to building.

But don't worry, if you have any problem with indoor signal you can download our free Three inTouch app which keeps you connected in more places.
