How it works

This mobile phone signal amplifier is designed even for less experienced users who have little or no technical background at all. The booster set includes several elements. Each of them has its own role and all together they are able to help you forget about your signal issues even if your house or office is situated in a zone with very poor signal reception. The standard kit has a booster box that is responsible for strengthening the signal after it is caught by an outdoor antenna. After being improved, the signal is sent to mobile devices with the help of an indoor antenna.

To ensure the excellent functioning of your Nikrans BD-250FG, you need to install all the elements of the device correctly. The entire process of booster installation is described in detail in the User’s manual that will be sent together with each order. Usually, the booster installation doesn’t take long but we advise you to be very attentive during this process and to follow all the recommendations. For example, the vertical distance between two antennas should be at least 10 meters.

If you have any questions regarding the installation, you can always contact our team and get the necessary assistance from our experts.

In case of any other issues or doubts, do not hesitate to let us know. We will be happy to help you!

Enhanced Connectivity with Nikrans BD-250FG 4G and GSM Signal Booster


I recently purchased the Nikrans BD-250FG Booster for 4G and GSM, and I must say it has exceeded all my expectations. As someone who constantly dealt with frustrating signal loss issues I was eagerly looking for a solution and this booster turned out to be a real marvel.

The installation process was a breeze. With the user-friendly instructions provided I had no trouble setting it up. What surprised me the most was that the booster started working immediately even before any calibration or mounting. The moment it powered on I could already notice a significant improvement in my signal strength. It was an instant relief to have a stable connection without any dropouts.

One aspect that truly impressed me was the exceptional customer service from Mobile Signal Boosters Shop. Throughout the process, they actively reached out to check on my installation progress and offered assistance. It's rare to come across such proactive and caring customer support and I'm genuinely pleased with the level of service they provided.

As for the technical specifications, the Nikrans BD-250FG is designed for both 4G and GSM signals. The booster supports multiple simultaneous connections, so my entire family can now enjoy seamless connectivity.

Regarding the antenna installation I decided to mount it on the side of my house, close to the satellite dishes. This strategic placement worked wonders for me ensuring optimal signal reception and amplification.

I highly recommend this booster to anyone looking for a reliable and powerful signal amplification solution.

Improved Cell Service at Home: Nikrans BD-250FG 4G and GSM Booster Review


Living in an area with dismal cell service, our struggles were magnified when indoors. Our hopes were modest, aiming for just one extra "bar of signal strength. However, the Nikrans BD-250FG 4G and GSM Booster exceeded our expectations by delivering a remarkable gain of 2-3 bars and even full service indoors. Installation, a task my husband tackled, proved to be a breeze, and the immediate difference in signal quality was truly impressive. The team at mobile-signal-boosters.shop displayed outstanding support, keeping in touch via emails to ensure our satisfaction and promptly addressing any inquiries we had. I wholeheartedly recommend this solution to others facing similar challenges.

Here are a few valuable insights I gained from this experience:

  • Properly align the external antenna with the best available signal. Give it time to establish a connection before adjusting its direction further. Rushing the rotation might cause you to miss out on a strong signal.
  • When placing the exterior antenna, opt for positioning it on the edge or side of your home that points towards the signal source, rather than installing it in the middle of the roof.

In conclusion, the Nikrans BD-250FG 4G and GSM Booster has significantly improved our home's cell service. It's a reliable solution that has not only increased our signal strength but also provided enhanced indoor connectivity.
