Are you tired of dropped calls, poor voice quality, and dead zones when using your Verizon phone in your home or business? Are you in an area that commonly experiences low coverage, where you're lucky to get two or three bars on your phone at a time? For Verizon Wireless customers, the solution is here. Subscribers are now able to boost their network signals with the launch of the Cel-Fi DUO+ for Verizon cell phones. Item name: 31-D32-2/13/66.

All you need is one bar, and this Nextivity Cel-Fi DUO+ Smart Signal Booster for Verizon designed for use on 4G LTE (including VoLTE) and UMTS networks. It will allow you to boost your signal to five bars with ease. Dulled indoor network experiences that result from network signals hitting walls will now be a thing of the past, with the FCC approved 100dB boost providing up to 13,000 ft. of coverage with every unit. Nextivity Cel-Fi DUO+ Smart Signal Booster for Verizon.

The Cel-Fi DUO Plus is small and compact, packed with features, and requires minimal setup. It is a plug and play booster. All you need to do is place the units where you need the most coverage and, and both will configure themselves and communicate as needed. There is no extraneous cabling or antennae. The CelFi DUO also offers boosting for UMTS/WCDMA voice signals on the Verizon network, and uses patented echo-cancellation algorithms for stronger, clearer signals. Therefore, dual band boosting on frequencies 2 (1900MHz), 4 (1700/2100MHz), and band 13 can occur simultaneously.

The Verizon Cel-Fi DUO + is made up of two separate units. The window unit captures signals from the closest Verizon cell tower within range and sends it inside the building, where the coverage unit then takes over by providing boosted signals in the surrounding home or business. Automatic channel selection feature on the 5 GHz link makes sure there’s no interference with Wi-Fi routers, cordless phones, baby monitors etc.

The Cel-Fi DUO comes with one (1) Network Unit, one (1) Coverage Unit, two (2) Power Supplies, two (2) Mounting Brackets and a Quick Start Guide. Cel-Fi DUO+ warranty period is two years from the date of purchase.

This cellular repeater kit is for Verizon Wireless network users looking for an easily-installed, powerful signal booster for areas up 13,000 square feet without needing to run cable or mount antennas outside. The coverage area can be up to 15,000 square feet. It supports 4G LTE, XLTE, and VoLTE (HD Voice) for Verizon network only. It is NOT compatible nor approved for use with ANY other carrier. It will not help with Verizon 3G, and it will only help with voice/calling if you have HD Voice/VoLTE enabled on your phone, and are in an LTE area. Alternate model no. D322/4/13, D322/13/66, D322413, D3221366.

Cel-Fi does not require installation of external antennas and handset registration, or a configuration setup by the user. Cel-Fi intelligently and automatically senses and adapts to its environment. It adapts to changes made by Verizon to its network, and to changes caused by nearby equipment like Wi-Fi. Multiple Units of Cel-Fi can be deployed in large offices and will not interfere with coverage strength. Cel-Fi is radically different from traditional repeaters. Cel-Fi is the only intelligent booster that is wireless-in/wireless-out. The Network Unit receives the signal from the mobile network (it requires as little as one bar of signal) and relays it wirelessly to the Coverage Unit that amplifies it for up to 100 dB of gain.

Note: The Cel-Fi Duo+ does not change between carriers via the Wave App. Only the Go-X and Go-M are interchangeable across the carriers. This has to do with the firmware makeup of these different models. Cel-Fi manufacturer requires returns be in mint condition or will incur re-stocking fee of 25%. Please ensure that if this brand product item has to be returned, it must be received in mint, resaleable condition. Thank you very much.

Questions & Answers


Ask a Question
  • I have trouble getting a signal down at my basement office; would this work for me?

    Yes, it will. However, it will only do so if you have mobile service through Verizon Wireless.

  • Will this work with the new 5 g cellphone signal that might be in my area in the next 2 years?

    Possibly, if Verizon opts to choose existing frequency bands to trasmit 5G signals. Read about DSS for more details.

  • I want the Cel-Fi DUO, but I'm not sure if it will be able to cover both floors of my 2 story home. Will it?

    No, you will most likely need two kits - one for each floor. For a double story home, it may be best (optimal coverage) to use a Nextivity Cel-Fi GO X with outside yagi donor antenna and two indoor SISO omni antennas (one per floor). This would help insure good coverage throughout the home. This greatly depends on the size of your home too, so if you think interior of the home would be good enough for one Wi-Fi router throughout the entire home, then likely one Nextivity Cel-Fi DUO+ kit would be sufficient.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
