Do you experience dropped calls or choppy, incoherent conversations on your Sprint cell phone within your home/office or in car/truck? Sprint cellphone coverage is very good - However, housing materials such as concrete, metal, low emissivity or tinted glass windows, etc. block cellular signals and prevent good mobile reception indoors in homes/offices and outdoors in cars/trucks. Up to 100dB carrier grade cell phone signal boosters include Cel-Fi GO+ for Sprint, Cel-Fi QUATRA 2000 for T-Mobile and Sprint, and Cel-Fi QUATRA 4000 for Sprint, T-Mobile, Verizon, and AT&T.

You may read more details at FCC website. All of the following cell phone signal amplifiers are FCC certified and tested to improve wireless reception in homes or buildings, cars, trucks, boats, recreational vehicles (RVs), etc. on Sprint mobile network. Try one risk-free to see how much it helps you to minimize dropped calls, missed calls, stuck/late text messages, and slow mobile internet due to weak cellular reception. As long as there's some minimal cellular signal outside the home/building or vehicle, you will definitely experience remarkable cell signal amplification inside.
