Good to Know

Understanding Your
Coverage Results

Building Materials

Thick walls, metal cladding, and double glazing can reduce indoor signal. If outdoor coverage is strong but indoor is weak, WiFi calling can help.

Terrain & Location

Hills, valleys, and dense woodland can affect signal strength. Coverage may vary from the map in extreme terrain conditions.

Network Upgrades

5G coverage is expanding rapidly. If 5G is not available in your area today, check back regularly as new masts go live every week.
