Cell Phone Signal Booster FAQs
What is a Cell Phone Signal Booster?
Cell phone signal boosters, also called cell phone boosters, repeaters, signal amplifiers, or network extenders, increase the coverage of a cellular network. They boost 5G and 4G LTE signal across all major American carriers.
Installing a cell phone booster in a building will end your dropped calls, unsent texts, and slow data speeds. You will never have weak signal or dead zones again.
How Does a Cell Phone Booster Work?
Cell boosters work by pulling in your existing outside signal, boosting it, and rebroadcasting it into desired areas.
Boosters also work in reverse. The unit receives outgoing signals from nearby cellular devices and sends them to your closest cell tower.
There are different types of boosters available that target different needs:
- In-Building Signal Boosters – Designed for homes, offices, and commercial buildings.
- Vehicle Signal Boosters - Designed for cars, trucks, RVs, SUVs, boats, and fleet vehicles.
For a cellular amplifier to work, there must be existing signal outside your home, office, or vehicle. Even if weak, the cell signal booster can give it a boost.
Critically, a cell phone signal booster enhances existing cellular signals. It does not create them.
There are a minimum of four componets to every signal booster. These are:
- Outdoor (or Donor) Antenna
- Amplifier
- Indoor Antenna
- Coaxial Cable

Does a Cell Phone Antenna Booster Work with Different Carriers and mobile devices?
Yes. Most cell phone boosters are wideband, meaning they boost all major carriers (Verizon, AT&T, T-Mobile, US Cellular, DISH, etc.) at once.
However, some boosters are single-carrier, meaning they target that carrier’s specific cellular frequencies. These can usually be switched between carriers, but be sure to make sure your carrier is supported. This information can be easily found in each cell phone booster’s product page.
As for mobile devices, cell phone signal boosters do not discriminate and will work with any device you have.
Do These Cell Phone Boosters Work with 5G?
Yes and no, depending on the booster. Nearly all our boosters work with what’s called “low-band” 5G. These cover:
- AT&T 5GE and 5G, but not 5G+
- Verizon’s 5G Nationwide, but not 5GUW
- Select T-Mobile Extended Range (XR) bands (band n41 specifically)
Others cover more of T-Mobile's low-and-mid band 5G bands, and Verizon and AT&Ts mid-band offerings.
