Cell Phone Signal Booster WiFi: Mobile Reception or Home Coverage?

A WiFi booster can extend your router’s WiFi to a phone, but it does not amplify a mobile operator’s cellular signal. For calls over your broadband connection, check whether your handset and network support WiFi Calling.

A mobile repeater relays a cellular network signal between a base station and phones. A WiFi extender links to a home router and rebroadcasts its local WiFi network; they are not interchangeable.

Some repeaters can be installed without a licence if they comply with Ofcom’s technical requirements. Check Ofcom’s current guidance and device information before buying or using one.

It can help if the phone’s problem is weak WiFi from your router and the extender receives a good signal. It will not fix poor cellular reception when the phone is using the mobile network.
