Cel-Fi DUO+ for T-Mobile

Powerful 3G/4G/LTE signal booster approved and authorized by T-Mobile.


The Cel-Fi DUO+ (D32-2/4/12) is a powerful signal booster system that boosts T-Mobile 4G LTE voice and data. The Cel-Fi DUO+ offers up to 100 dB of gain and coverage up to 15,000 sq ft.

The DUO+ covers Band 2, Band 4, and Band 12 for T-Mobile. It requires at least one bar of LTE signal where the network unit will be located.

The Cel-Fi DUO+ system is very easy to set up. Anyone can install the device. No special tools or knowledge is required and there are no external cables, antennas, wires, or drills needed. The units simply plug-in to power.

The Cel-Fi DUO+ has an LCD color interface which provides instant visual feedback. It is fully self-contained and self-configuring. No ongoing maintenance is needed.

The DUO+ is best for T-Mobile users looking for an easy installation of a powerful signal booster without running cable or mounting outdoor antennas. It will boost any device using T-Mobile within the coverage area.

Cel-Fi WAVE Mobile App

Cel-Fi WAVE is a smartphone app that will help you get the best performance from your Cel-Fi DUO+. The WAVE app is available for desktop, iOS, and Android. The app's dashboard gives you a real-time overview of the system performance and allows you to optimize setup and download software updates.


The Network Unit (NU) should be placed where the existing cellular signal is best (generally by a high window). The unit requires at least one bar of signal to work. The Coverage Unit (CU) should be placed in the location you need improved signal. You can optimize coverage by moving the CU. The NU and CU communicate with each other wirelessly to provide the best signal improvement possible. Red and Green icons on the CU LED user interface will indicate whether the CU should be closer or further from the NU.


Mounting brackets and hardware are provided to mount either/both the Coverage Unit and the Network Unit. The brackets come equipped with screws and inserts for mounting in standard drywall.

The DUO+ comes with a 2-Year Warranty.
