This 3G booster functions at 3G 2100 MHz frequency. This frequency is used by all European and most mobile providers worldwide for 3G data transmission only, and it does not work with GSM phone calls and voice connection.

Benefits and features

Its major features are:

  • LCD display. The screen displays most important information including setup tips, error messages and solutions and system data.
  • Sleep mode. The device goes into sleep model in non active periods, which helps save energy.
  • Automatic operating control. The device has ACG function for adjusting gain depending on the outside signal. Also, ALC function for signal level regulation and auto shut-off in cases of self-excitation.
  • Multiple phone support. The 3g mini booster is able to support 100+ mobile connections simultaneously within its coverage area.

Kit contents and setup

We ship each repeater in a full kit together with the necessary items for installation of the whole system. 3G antenna booster Nikrans LCD-150 3G kit includes indoor and outdoor antennas, two cables, mountings, and a manual.

The installation is really simple and takes about 15-20 minutes. You don’t have to bear additional expenses on technicians as you will manage everything on your own. It’s only necessary to connect the booster with antennas with cables and then power the device on. Just in 5-7 seconds the 3G signal will reach 5 bars on your mobile phone.

The device is proved to be safe for adults and kids staying in the zone with amplified signal. It’s even more helpful as together with the better signal it brings a lower level of mobile phone emissions. In the area with weak or absent mobile signal radiation emissions from mobile devices exceed their normal value as mobile phones automatically start searching for a stronger signal. After being installed a Mini repeater will help to improve the signal and decrease extensive emissions.

LCD-3503G Customer Stories

Thanks to my cool mobile signal booster I managed to boost cell phone signal MTN

Marcel Fimpa (Congo, Boundji)

Though I live in a small town in Congo, I have never had any difficulties with GSM calls that’s why when I chose a new mobile plan that included 3G mobile internet (I had previously found out that my mobile operator was transmitting 3G signal across my area), I was really surprised that MTN 3G poor signal wouldn’t give me a chance to enjoy mobile internet at home. Something went wrong and MTN signal problems were obvious. To tell the truth, I had no ideas how to deal with these MTN 3G poor coverage.

But I knew that I really needed to boost cell phone signal 3g at home as I needed to use it not only for private communication or entertainment. I needed to use it for my studies as well, for example for downloading some materials or books, as I didn’t have a computer. And when I was really desperate, my groupmate advised me to visit MyAmplifiers web site. At that time I didn’t know anything about mobile signal boosters and their capacities to boost cell phone signal. But when I entered the site I found so much information about them! I easily managed to find several boosters that are designed to solve MTN mobile signal problems in Congo.

I could boost signal for cell phone Djezzy! Finally!

Sami Natouri (Algeria, Laghouat)

So I contacted MyAmplifiers, and they helped me at a pretty low and very fascinating price. This is actually pretty cheap if you think about the fact that the signal amplifier will boost signal for cell phone of Djezzy poor coverage and that it would work for a long time. I bought the booster that the company has suggested to me because of the size of my house and the type of signal I wanted to be strong. It arrived really fast, and it works really well. I was pretty much worried about how it will turn out because of the local climate. But the manager ensured me that it doesn’t matter and the signal amplifier will work perfectly at any temperature or humidity. And it’s true: I’ve never had any issues with booster’s work, even when it’s really hot outside.

My 4G internet connection is good at any time of day (Djezzy poor signal is forgotten!) I placed the booster box in my living room, and it looks pretty small and nice and doesn’t spoil the design. Also it isn’t surrounded by a lot of ugly uncomfortable wires, so no one trips over them at night. Djezzy signal problems don’t bother me anymore and I am so very happy that I managed to successfully boost signal for cell phone. I also recommended MyAmplifiers and their 4g signal boosters to a couple of my coworkers, and they also say that they are very happy with their purchase.

It was difficult to find how to boost phone signal Telkomsel, but we did it!

Lastri Pranata (Indonesia, Sengkang)

Can you imagine? I had been suffering from Telkomsel 3G poor coverage in our house for several years and was searching how to boost phone signal. But then just one device fully changed the situation! When LCD-3503G appeared in our house, I forgot about Telkomsel signal issues practically immediately.

Due to Telkomsel signal problems I used to feel very lonely in the evenings. Moreover, my parents also were not very satisfied that we didn’t have proper 3G signal that’s why my dad decided to try to install a mobile signal booster. According to a wide range of reviews and testimonials, a great number of people from all over the world have already understood how to boost phone signal with the help of these devices. That’s why we also wanted at least to try. But when we installed LCD-3503G, there was no even a single reason to regret! This reasonably-priced device is very powerful! Now all my messages in online messengers can be sent just in a second, I don’t need to wait for hours if I want to check my email box, and I can even make video calls. Our Telkomsel 3G signal has become really strong. Thank you, MyAmplifiers, for this amazing device!

It is such a small cute device! I even didn’t know that such a little box could be able to boost the signal. But in any case, I am happy that finally I’ve found this solution. It’s better late than never.

When we moved to a new house, we didn’t expect that we would face any issues with our Lycamobile signal but the reality differed from our expectations. Thank you, MyAmplifiers, for offering such a huge variety of boosters that everyone can find an ideal variant.

The repeater fully fulfills its functions, it perfectly improves the 3G signal and even when strong winds are blowing and it is raining heavily, the signal is okay, though earlier bad weather used to spoil our connection.

This booster is suitable for students, couples or families who live in apartments or small private houses. Even when the weather is awful, strong winds do not affect the quality of the 3G signal. The device has a very stylish and modern design.

After I managed to install a booster, everything is fine. Even though so many people say that it was easy for them to install a booster, for me it was a challenging task.

Armenia, Verified Buyer
Purchased Nikrans LCD-3503G
When you live in a mountainous area some problems with mobile connection are quite common, however, in our case we had something extraordinary. We have practically zero signal! That’s why we decided to buy a booster. It was our last hope! And the trial was a successful one. The booster works perfectly.
Strong signal The number of payment options is rather limited, so we had some difficulties in opting for the most appropriate one.

I still can’t believe that it is so easy to overcome signal issues now. I just installed this device and forget about all the difficulties. Actually, it looks like a miracle. Really! Thanks, Daniel, for your useful recommendations and assistance in placing my order.

Purchased Nikrans LCD-350 3G
Without a doubt MyAmplifiers is a great customer-oriented company who really try to help. The Live Chat is fantastic to help answer questions on which amplifier to buy. Having said that I would just advise purchasers two moments: 1- To get good indoor coverage you need more power. For the 400m2 coverage LCD 350 is really not enough but unfortunately the price goes up steeply for more powerful models. 2 The cable provided to connect the external antenna to the amplifier box is very thick and heavy. This leaves you with a problem in how to pass through a wall or window and makes simple installation difficult.
Great customer service, help and support. Good prices. Fast delivery. To get the power you need you have to buy a more powerful and more expensive amplifier. Installation is not quite easy as implied.

A very nice booster and a very nice price, exactly what we needed for our summer cottage. I think that we will buy the same model for our grandparents’ house.

The device is very useful. We installed it in our summer cottage to have stable mobile internet. And this task is perfectly fulfilled.
We installed it in less than 15 minutes though we had never seen such boosters before. Though I like the design, I can’t understand why only one color is available.
