About This Product
No more dropped calls, slow internet, & disrupted service
The Cel-Fi Duo+ Smart Signal Booster for Verizon or T-Mobile by Nextivity is part of the next generation of intelligent signal boosters. Because all Cel-Fi products are designed and developed using the most advanced radio frequency and signal processing technology.
With up to +100 dB gain of amplification, it greatly enhances 3G & 4G LTE cell service for all your wireless devices (smartphones, notebooks, hotspots, etc.) on Verizon or T-Mobile for any home or office up to 15,000 sq ft. This two-piece wireless system features the Network Unit (NU) and Coverage Unit (CU). The NU pulls in signal and the CU broadcasts the amplified signal throughout the home. No wires and easy set-up.
Unlike multi-carrier signal boosters with a limit of +70 dB, Cel-Fi’s single-carrier solution can boost signal up to +100 dB. That’s a difference of +30 dB or up to 1000x more power compared to multi-carrier boosters.
Never drop a call again. Stop waiting for loading screens. No more searching for reception. Get faster internet & updates on your apps. Send emails and text messages with zero delay. Stream video & audio with little to no buffering.
