How it works

Cell Phone Extender Nikrans LCD250-GSM+4G is a device that is designed to simplify your life. It not only perfectly fulfills its function (thanks to its two antennas and a repeater box itself it is able to amplify even the weakest signal and to transmit it to more than one mobile device at the same time), LCD250-GSM+4G makes its usages for you as simply as possible.

To install it, you may need just 30 or 40 minutes and then you can practically forget about it, as it is able to control the external circumstances and adjust necessary settings automatically. When there is no any necessity to improve poor signal as there are no any mobile devices that need to receive it, LCD250-GSM+4G enters an energy saving mode. Moreover, when the necessity appears, an active regime will be switched on also automatically.

It does increase signal

I had a few spots in the house that could not sustain a call. Using a signal strength app on my smartphone I figured out where to mount the antenna. I managed to run the cable without drilling any holes. I set the indoor antenna in the attic right over the area that I most wanted to improve coverage. That’s why I didn’t have to drill any holes in the interior walls. Coverage went from 1 bar to 4 bars.

Dear Robert, we appreciate your feedback. Thanks and regards, Support team.

Tricky to install

The house I live is incredibly rural. I had only 1 signal bar. If the device is properly and carefully installed, this does the trick. Now I have 4 signal bars inside. The problem is that the exterior antenna is highly sensitive to positioning. Any movements can influence on signal bars.

Dear Bob, thank you for contacting us, we greatly appreciate it. Best regards, Support team.

More Bars for sure

We installed one of these amplifiers at a cafe in rural Derry. The nearest cell tower is about 6 miles away. We got about 1-2 bars outside and absolutely no cell service inside the building. After the installation, we had enough coverage to make a phone call and send a text in the whole cafe. We don't get 5 bars but it gets 3 to 4 bars and that is plenty for the cafe. Customers with different cellular providers reported improved cell service. The installation process took about an hour. 4G wasn't the fastest, but it wasn't good enough outside either.

This device however doesn't work miracles. If you have no coverage, this booster isn't for you. For a larger building, I also recommend other models, but overall, this product does the job well. Price is reasonable.

Dear Noar, we’re pleased that you are satisfied with the results. Kindest regards, Support team.

Case Studies

Paul Dass, Swindon

Quick delivery with all necessary parts

Fast delivery is everything! My situation was an emergency, since no one at my company could work efficiently while having terrible Vodafone signal problems, and the cell phone booster I ordered arrived in just a couple of days, exactly as it was promised. No mistakes during the delivery or with the order, every single detail is very carefully packed and there’s no need to buy any additional wires or power plugs.

Philippe Doherty, Huddersfield

The signal is stable and strong now.

I tested out the signal for several days after I turned on the booster. It was stable anywhere inside the working range of the booster, my internet speed was very good no matter what I was doing and where I was, and I could do anything that I needed – from interviews via videochat to watching movies online. The signal never interrupts or slows down my working process anymore, and it honestly feels very good.

Dwyer Jacox, Grimsby

It was time to stop my Lycamobile signal problems!

Due to some circumstances in my life, I had to move out of a big house and live in another part of the town. It all caused me no problems except for one thing. There were no Lycamobile signal problems at my old place, but the new apartment had severe signal issues. I was basically erased from my friends’ and family radars, because they couldn’t reach me. It was frustrating, and something really needed to be done.
