This Cel-Fi Smart Signal Booster is licence exempt under UK law and fully meets the requirements of Ofcom SI 2018/399.

Cel-Fi PRIME is the perfect mobile signal booster for flats, storefronts, kiosks, apartments, offices or similar spaces. Being 10x stronger than traditional analogue boosters, it strengthens both 3G and 4G signal coverage on the Network or your choice (swapping networks between the available ones is also possible using the WaveApp ? see below).


With 80dB of gain, Cel-Fi PRIME will not only improve mobile signal coverage, it will also reduce the device?s power requirements and extend its battery life. It offers plug-and-play mobile signal coverage, enabling clear and reliable connections within a coverage area of up to 100m2 (approximately 1,000 sq.ft.). In an open space, the coverage bubble can be much larger.

Cel-Fi PRIME uses Nextivity?s award-winning signal boosting technology, addressing pilot pollution issues and ensuring it outperforms the competition. Cel-Fi PRIME is legal to use in the UK, it is CE-certified, and available wherever Bands 1 (2100 MHz) and Band 3 (1800 MHz) are used.
