Mobile Signal Booster Reviews for the UK in 2022

Table of contents

In the abundance of mobile phone signal boosters in the UK, it is often hard to make the right choice for your home, office, or vehicle. Mobile phone signal boosters can significantly improve the quality of your calls and provide a better experience. However, not all boosters available on the market can be legally used in the UK.A signal booster (or repeater) incorporates an outdoor antenna, a booster to amplify the signal, and an indoor antenna that allows it to enhance the connectivity in your building. In this article, we will go over the available mobile signal boosters and discuss the main features of each device.

Usage of mobile signal repeater devices or boosters is illegal under Section 8 of the WT Act 2006, but some devices are exempt from this law for in-building and vehicle use. Unfortunately, it is still legal to sell repeater devices that do not comply with the law—it only talks about installing and using them.

If you purchase the wrong type of repeater device, you might face a fine of up to £5,000 or up to a year of imprisonment. The distinction lies in the interference with the mobile networks. If a device does not interfere with other networks and adheres to Ofcom’s licence exemption conditions, your repeater is safe to use. Keep on reading to learn which of the best mobile signal boosters are legal to use in the UK.

6 Best Mobile Phone Signal Boosters in the UK

To help navigate the available options for boosting the mobile signal in a building or vehicle, here is a compilation of six mobile signal boosters from Cel-Fi, which are legal to buy and use in the UK.

Cel-Fi Prime is available on the 3 and EE networks in the UK.  It can boost the mobile network signal by up to 80dB and provide better 3G and 4G services. Having a stronger signal can also extend your phone’s battery by reducing the power it consumes to connect to the network. 

Cel-Fi Prime provides improved coverage and offers reliable and stable connections. The technology behind the device allows it to address pilot pollution issues that cause poor signal when several mobile signals at one location compete with each other. Cel-Fi Prime comes with Nextivity’s electrically steerable antenna technology, which provides industry-leading performance and is available in the UK and other countries.
