NS550-GSM+4G Customer Stories

With a cell phone booster kit I forgot how to live with VIPnet signal problems.

Juraj Delic (Croatia, Taborište)

I live in countryside in Croatia. It is a rather mountainous area, I should mention it. Maybe due to these landscape peculiarities, our family was deprived of normal mobile communication. VIPnet poor coverage was a real obstacle for us each time when we wanted to make a call or to browse the net. Honestly speaking, I didn’t know that it is possible to improve VIPnet poor signal, I believed that it was just our fortune to tolerate with the fact that we live in the area with bad mobile connection. Nevertheless, I changed my mind when I read in an article on the internet that VIPnet mobile signal problems can be solved with the help of a cell phone booster kit.

We needed a really reliable company that can offer us a device to boost all types of VIPnet signal. In MyAmplifiers catalogue we saw that there is a variety of different devices that can be installed in our house. One of these options was NS550-GSM+4G. This cell phone booster kit has not a very wide coverage if compared with some other signal repeaters (but for us it is sufficient) and it is able to amplify VIPnet GSM, 3G and 4G/LTE signals. Now we have amazing mobile connection in our house! It is a dream that has come true!

Unbelievably better cell signal! No more Yesss! signal problems!

Chris Jagstberg (Austria, Kleinreifling)

So one day I wondered whether it was possible to do something with this deplorable situation and to get better cell signal Yesss! in my house. On the internet I found some information about signal repeaters. Once I’ve heard about them from my neighbor so I decided to try one as well. At MyAmplifiers I found a wide range of boosters, some of them were suitable for improving GSM calls only, others for bettering 4G connection. My eyes were dazzled by such diversity.

I wrote to the support team and they advised me to choose Nikrans NS550-GSM+4G model. It provides better cell signal within indoor coverage of 550 m2 and is suitable both for enhancing the quality of voice communication and for stabilizing 4G/LTE connection. It supports EGSM 900 and one of LTE bands upon your choice - LTE 2600MHz and LTE 800MHZ. Immediately after the installation of the device Yesss! poor coverage disappeared from my house. The whole family enjoys smooth high-speed LTE Internet and excellent voice connection. Yesss! signal issues cause no troubles any longer. I strongly recommend this repeater to everyone who wants to do away with Yesss! poor signal and to stay connected around the clock.

Wind signal problems causing nuisance at our villa. Mobile cell booster saved our nerves!

Thanasis Mekion (Greece, Vargiani)

I bought GSM 4G/LTE mobile cell booster Nikrans NS-550 GSM+4G because I had to cope with frequent Wind signal problems which occurred on my villa located in Vargiani, Greece. Actually, this is one of the most mountainous areas in the country, therefore Wind poor reception leaves much to be desired here. I would like to admit that the signal booster surpassed all my expectations. The full kit completely corresponds to the description given on the official website of the company. I received the mobile signal booster box, indoor and outdoor panel antennas with cables each, power supply and a detailed user manual. All the necessary mounting accessories were included, so I just unpacked the delivery and installed the device. By the way, the whole process of installation took less than 15 minutes, everything was clear due to the manual attached.

As for the functioning of the mobile cell booster itself, I have absolutely no complaints and discontent. Immediately after I had turned it on the signal repeater started to boost Wind poor coverage in my villa. It’s really fantastic and even unbelievable that I finally got rid of Wind signal issues and now I can enjoy perfect GSM connection, make and receive calls without being irritated and dissatisfied, moreover the signal booster enhances 4G connection as well, so apart from high quality voice connection I benefit from speedy internet too.

Awesome repeater. I am not a tech specialist that’s why I can’t characterize its technical parameters and other related things. But I see that it works well. I had no problems with its installation even though it was my first experience with such a device.

I am very happy that my dad agreed to buy this device as earlier he didn’t want to buy it due to his fears concerning the possible harm that such boosters can cause to our health. I needed to spend hours explaining to him that they are not dangerous. Thanks for useful articles on the website. I used this info to convince him.

Guys, thank you for this amazing booster and for your amazing work. I was really impressed with the quality of your work. To tell the truth. I am a very demanding customer, especially when it comes to online purchases. I want to know everything about the product before I order it. I think that I have called the support managers for 4 or 5 times (maybe more, I don’t know) and each time I have asked hundreds of questions. But I’ve always received very detailed and very professional replies. Though later I have found out that all the information that I needed is presented on the website, the managers remained extremely polite and patient. The device itself is also cool. It functions without any interruptions and ensures stable GSM and 4G coverage (I couldn’t wish more).

I bought a gsm+4g amplifier for our house, located 30km from Madrid. I installed all the equipment in a hour, even not having any technical background. The most important is that my family is satisfied, my children can make calls from their rooms and my wife can telephoning from our kitchen. In my opinion the price is not so high for 500 m2 coverage capacity.
This is a good amplifier with an impressive coverage capacity for reasonable price.

Purchased Nikrans NS550-GSM+4G
Thanks! The order was delivered very quickly. We didn’t have any problems with installation but at first, my phone couldn’t catch the improved signal (though my mother’s phone caught it immediately). I don’t know why and how it happened but the next day everything was okay. Since that time, I haven’t had any problems.

Thanks for a high-quality device. Earlier, in our house, our GSM signal was so bad that we couldn’t make calls and there was no 4G coverage at all. Now I can even watch films on my smartphone and make video calls!
High capacities. Price. For me personally, such a price is rather high.

To tell the truth even when I placed an order, I was not sure whether it was a good idea to buy this booster. However, now I regret not buying it earlier! :)

Purchased Nikrans NS550-GSM+4G
My first impression of this booster was great: it is an excellent amplifier for a reasonable price. Finally my phone can catch 4-5 bars of signal. I also liked an easy installation, it took me only 1 hour. The most important is to read the user guide first. I found a right place and fixed the outdoor antenna so it was as high as possible. I've heard that many people suffer from lightning damage of outdoor antennas, so I decided to put a lightning conductor close to my antenna. In general, i would recommend this amplifier to everyone who suffers from very pour signal in the house.
As I mentioned, reasonable price, easy installation, great function, detailed and useful user guide. As a huge plus, an amplifier reduces radiation emitted by your cellphone. Outdoor antenna can be damaged by a lightning.

I am soooo happy that we’ve installed this booster in our summer cottage. We do not have a TV set there and our mobile internet used to be awful. But thanks to the booster that we bought in May we could watch all the games of the UEFA EURO 2020. Have you seen the final?! I do not know whether I would ever forgive myself if I had missed that match!

Thanks for all MyAmplifiers' team for your help in choosing the right booster for me. I like everything, functioning, attractive price, quick installation and fast delivery. This repeater works well with our provider MEO and covers two floors of our small house. Also it supports 5 mobile phones in the same time without any interference.

I decided to order this GSM+4G booster from as my best friend have bought from them and said I could trust this company. I risked and don’t regret as they helped me a lot. I don’t know anything about signal booster sets, I just told them how big is the office building, how many storeys it has and what I want from the equipment. Then they gave me detailed information, explained the ins and outs of its performance and advised me this Nikrans booster, and it works excellent! Thanks you, guys!
large coverage, 4 storeys are covered (though I bought a splitter for that), stable connection and access to Internet. Good and professional specialists in support team.

Thanks for this amplifier. It suits me perfectly and is able to improve our awful GSM and LTE signal. At first, I wanted to order two separate boosters for these two types of signal but when I contacted a manager for a consultation, she explained to me that this one would be enough. I am very grateful that thanks to her professional help I could save my money. It was very easy for me to install this device and there are no problems with its functioning.

When I received my order, I was very disappointed to find out that something was wrong with one of the cables. Though at first glance everything was already when I connected my outdoor antennas with an amplifier box using it, it became obvious that the cable was damaged. I contacted the support service and just in a couple of days, I received a new cable. The first impression was a little bit spoilt but now everything is alright and I am very satisfied.

For me, it was a real discovery to find out that something like these boosters is available today. Though I was suffering from problems with my mobile signal at home for a couple of years, I couldn’t even imagine that one day this problem will be solved so easily. It was my friend who sent me a link to this website. I don’t know where he had found it but my family is very grateful for him. So, we ordered this device because (first of all) the price seemed to be very attractive and it had all the functions that we could wish. Now after we have installed it, the internet connection is just perfect, it is amazingly stable and the speed is really high. The quality of voice services has been also improved but to tell the truth we all use the mobile internet much more often than our voice services.
Quite a bulky system - antennas, cables...
