How to Improve Mobile Phone Signal Indoors
Poor mobile coverage in a house or office can make calls unreliable even when the phone works outside. Thick walls, metal-backed insulation, distance from a mobile mast and network congestion can all contribute to weak indoor signal.
Check whether the issue is the mobile network
Start by checking your provider's coverage map and service status for your postcode. Compare reception inside and outside the property, and ask someone using a different network whether they encounter the same issue. Your provider can also help you rule out faults with the SIM, handset or mobile service.
Try Wi-Fi calling
Most UK mobile providers support Wi-Fi calling on compatible phones and tariffs. This allows your handset to make and receive regular calls over a reliable broadband connection where cellular reception is poor. Check the feature is enabled in your phone settings and supported by your provider.
If calls over Wi-Fi also fail, the underlying problem may be patchy Wi-Fi coverage rather than the mobile network.
Improve the Wi-Fi connection throughout your home
If you rely on Wi-Fi calling, a router hidden in a cupboard or behind thick internal walls may be part of the problem. Move the router to a more suitable position where practical and compare signal in different rooms. For larger properties, additional wireless access points with wired Ethernet backhaul can offer more predictable coverage than relying on a single router.
Read our guide to hardwired access points versus mesh Wi-Fi to understand the trade-offs.
Be careful with mobile signal boosters
Mobile signal repeaters are subject to UK regulatory requirements. Avoid purchasing unverified repeaters that may interfere with mobile networks. If improved mobile-network coverage is needed rather than Wi-Fi calling, ask your mobile provider about compliant options and availability at your address.
When is professional home networking useful?
If broadband reaches your router reliably but some rooms have consistently weak Wi-Fi, a suitable cable run and additional access points may help. This will improve Wi-Fi and potentially Wi-Fi calling, but will not directly strengthen the mobile operator's radio signal.
