Three Signal Booster UK: Nikrans 5G, 4G & GSM Boosters for Home, Business & Vehicles
Experiencing a weak Three network signal? You’re not alone. Many users across the UK face dropped calls, slow mobile internet, or even complete loss of reception — especially in rural areas, basements, or buildings with thick walls.
The solution is a Nikrans Three signal booster, designed to improve coverage on the frequency bands used by Three in the UK: 700 MHz, 800 MHz, 1800 MHz, and 2100 MHz.
Nikrans mobile signal boosters provide stable mobile signal for homes, offices, shops, vehicles, boats, and caravans. Whether you live in a stone house in Yorkshire or run a small business in Manchester, you can enjoy stronger signal, clearer calls, and faster data — even if the outdoor reception is very poor.
All kits are easy to install and come with a 3-year warranty and free technical support. We offer fast UK delivery and a wide selection of best-selling models, including 3-band and 6-band boosters, with coverage options from 3,300 ft² up to 21,500 ft².

Why Select a Nikrans Three Mobile Signal Booster?
A poor signal can negatively impact your daily routine if you depend on Three for calls, texts, or mobile data. Contemporary houses with energy-efficient windows, concrete walls, or far-off locations frequently obstruct signals for 5G, 4G, and GSM. A mobile repeater (also known as mobile signal booster) picks up the current outdoor signal, strengthens it, and sends it back in — thus, improving coverage straight away.
