Do NOT purchase a cell amplifier for areas, that have zero signal. If there is nothing to amplify, then zero times anything is still zero. If you have 1 bar, then an amplifier will make your calls better. If you have no bars, then following the instructions below to place your phone into test more to see if you have a very weak signal, that can be amplified. It should stand to reason, that cell phone amplifiers do not amplify landline broadband Wi-Fi internet from cable and satellite.
weBoost Cellular Boosters cover voice, 3G, and 4G LTE for all the major carriers. So, why not Sprint Spark? Sprint Spark is considered 4G LTE, but the network uses a combination of these bands: 800 MHz (the old iDEN freq), 1900 MHz, 2500 MHz (the old Wi-Max freq).
weBoost's new 4G line of products will cover 700, 850, 1900, 1700/2100 MHz. This means that the new boosters will cover the 1900 MHz, but not the lower end of the 800 MHz band, and no coverage for the 2500 MHz. Although the weBoost's 4G boosters will not cover the Sprint Spark network, they will still support the voice and 3G for Sprint’s network.
What is dB Gain? Cell phone signal strength is measured in dB (decibels). Typically, -50 dB represents a great signal (full bars) and -110 dB is virtually no signal (dead zone). As we said above, no amplifier will work without a signal to amplify.How to put Cell Phones into Field Test Modes
Why a weBoost cell amplifier? Simple. weBoost Cell Amplifiers have up to the highest allowable output power of 1 watt, while most others have only about 200 to 300 mill watts which is about .2 or .3 watts. Would you expect any less from Wilson? weBoost Cell Amps have a max gain of 50 dB, which is the maximum allowed by the FCC.

Place the Internal antenna as close to the cell phone as possible. This will help you get the most from your amplifier which is no where near as powerful as the cell tower. It is similar to getting closer to the cell tower to get a stronger signal.
