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.

If you're having problems with your indoor signal, don't worry. Three inTouch is here to keep you connected in places you didn't have signal before.
