CEL-FI GO G41 | Mobile Phone Signal Booster for Home | 4G, 5G, EE, Three, O2, and Vodafone | Up to 15,000 Sq Ft Coverage | 100 dB Cell Phone Signal Booster | Ofcom Approved | 1 Antenna Kit

UK customer on O2 network. Product worked for me! Perseverance in setting up was worth it. Easy to follow instructions and top customer service (bearing in mind the customer vs supplier time difference) for best install results. 3 months later I still have a reliable signal throughout my property, which I never had prior to installing.

This is a great piece of kit, easy to set up and made an immediate difference to my phone signal. I am fairly remote with no landline or tv aerial and needed to walk about outside to try and get a signal for a mobile phone call. After installing the Cel-Fi booster I now have 4 bars of signal and the added benefit of stable 4G which I can use for my broadband and tv streaming.
