Review: The FlareDB+ Cell Signal Booster by SureCall

We are all working from home these days, and not everyone has decent Internet connectivity, or even cellular coverage. My wife often finds herself working at her mother's house, and it sits in a valley with spotty coverage. This was the perfect opportunity to try the new FlareDB+ ($197.99) that SureCall sent me to try.

The device is very well-built and is assembled in the USA. There's some assembly of your own to do as well, since the device comes in at least three pieces. You have the base unit that looks like a modern art version of a Wi-Fi router, plus a very long (50-foot) coaxial cable similar to what you'd see for cable TV connections, and a sharkfin-style antenna that must be mounted outside the house. This is a requirement, and you may even need to get permission from your cellular provider to use any signal booster, so check with your provider first.

Because the antenna had to be mounted outside the house, it took some effort. Fortunately the kit includes several mechanisms for attaching the antenna to a variety of surfaces or poles. Once installed and set up properly, the FlareDB+ does indeed boost both voice and 4G LTE data coverage. No more dropped calls or spotty downloads. It works with just about any cellular provider including Verizon, T-Mobile, and AT&T. If placed centrally, the FlareDB+ should cover even a large home, up to 3,500 square feet with support for multiple simultaneous users. 



  • Boosts voice and 4G LTE service for any phone provider such as Verizon, T-Mobile, and AT&T
  • Covers even a large home, up to 3,500 square feet
  • Supports multiple simultaneous users
  • Well-built and assembled in the USA


  • Antenna is meant to be installed outside so you may need to do some drilling
  • You may need to check with your provider to make sure signal boosters are allowed

Final Verdict

If you need to boost your data and/or voice coverage, check with your cellular provider to make sure you're allowed to do so. If you are, the FlareDB+ from SureCall should be able to keep you connected.
