About This Product

No more dropped calls, slow internet, & disrupted service

The Cel-Fi Pro Smart Signal Booster for AT&T 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 AT&T for any home or office up to 13,000 sq ft.

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.
