No Mobile Signal? Here's What to Do

Practical solutions for poor mobile coverage at home or in rural areas.

1. Enable WiFi Calling (Free)

The simplest fix. WiFi calling uses your broadband to make calls and texts when mobile signal is weak. All major UK networks support it:

EE: Supported on most smartphones from 2018 onwards
Three: Called "Three Super Voice" — enable in app or settings
O2: Called "O2 WiFi Calling" — enable in settings
Vodafone: Supported on iPhone and most Android devices

How to enable: iPhone: Settings > Phone > WiFi Calling. Android: Settings > Connections > WiFi Calling.

2. Signal Boosters

A signal booster amplifies weak outdoor signal and rebroadcasts it indoors. Important: only Ofcom-compliant boosters are legal in the UK.

Frequently Asked Questions

Are mobile signal boosters legal in the UK?

Most signal boosters are not Ofcom-approved and technically illegal to use. However, Cel-Fi boosters are legally compliant as they are network-aware and do not interfere with other users.

What is WiFi calling?

WiFi calling uses your broadband connection to make calls and send texts when mobile signal is weak. All four major UK networks support it on most modern smartphones.

How do I enable WiFi calling?

On iPhone: Settings > Phone > WiFi Calling. On Android: Settings > Connections > WiFi Calling. Your network must support it and it may need enabling on your account.

Do femtocells still exist?

Traditional femtocells (like Vodafone Sure Signal) have been discontinued. WiFi calling has largely replaced them. For persistent issues, consider a Cel-Fi booster or external antenna with a 4G router.
