Cel-Fi DUO+ Signal Booster for T-Mobile 4G LTE Model # D32-2/4/12, SKU 590ND32GWUS1TMUS1BG or 590ND32GWUS1TMUS1BG1 (New, Stock A), UPC 697691004228. Item name: 31-D32-2/4/12. This cellspot signal booster is similar to branded Tmobile Wireless Router Personal Cellspot WiFi model. This Cel-Fi branded Cell Spot for T Mobile does not require broadband home Internet service for it to work. Nextivity Cel-Fi DUO+ Smart Signal Booster for T-Mobile.

Are you tired of dropped calls, poor voice quality, and dead zones when using your T-Mobile 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 T-Mobile customers, the solution is here: T-mobile DUO+ signal booster. Subscribers are now able to boost their network signals with the launch of the Cel-Fi DUO Plus.

All you need is one bar, and this celfi tmobile smart signal booster designed for use on 4G LTE (including VoLTE) and UMTS networks, 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.

The Nextivity Cel-Fi DUO+ Smart Signal Booster for T-Mobile is small and compact, packed with features, and requires minimal setup. This cel fi t mobile kit is a plug and play booster - all you need to do is place the CelFi Tmobile window unit and them the coverage unit where you need the most coverage. Both will configure themselves and communicate as needed. There is no extraneous cabling or antennae. The DUOPlus also offers boosting for UMTS/WCDMA voice signals on the T-Mobile network, and uses patented echo-cancellation algorithms for stronger, clearer signals. Therefore, triple band boosting on frequencies 2 (1900MHz), 4 (1700/2100MHz), and band 12 can occur simultaneously.

The Cel-Fi DUO Plus is made up of two separate units. The window unit captures signals from the closest T-Mobile 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 CelFi 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.

Questions & Answers


Ask a Question
  • Does this model support an external antenna?

    While this unit has an exterior antenna connector, this model does not require an exterior antenna to be mounted on top of the house or building. It uses a 1 ft. x 1 ft. the box-like unit that serves as an amplifier and exterior antenna and another similar box the serves as the interior antenna to be placed in an area with weak reception. 

  • Could you please tell me the between T-Mobile Personal CellSpot 4G LTE Signal Booster V2 cel-fi Model NXT CEL FI-D32-21266 and the Cel-Fi DUO+ Signal Booster For T-Mobile Model 590ND32GWUS1TMUS1BG1/D32-2/4/12? I have the T-Mobile Personal CellSpot 4G LTE Signal Booster V2 and was wondering if the Cel-Fi DUO+ Signal Booster For T-Mobile works better.

    T-Mobile Cel-Fi DUO+ will probably work the same as your CellSpot because it is made by the same company (Nextivity) and both are totally indoor systems with no outside antenna. If you need to greatly improve in-building cellular signal coverage, we recommend the Cel-Fi GO signal booster because it has exterior antenna that can be mounted higher up on outside wall or roof which can help it catch signals directly from outside much better than the Cell Spot or Cel-Fi DUO+ network unit placed indoors, even near a window.

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.
