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.

Purchased Nikrans NS550-GSM+4G

I decided to order this GSM+4G booster from Myamplifiers.com 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, the device is awesome. We bought it for our office. Though some members of our team didn’t believe that any amplifiers could help us, they were wrong. The booster turned out to be exactly what we need. Now we can communicate with our clients without any troubles. By the way, the delivery was so fast that we were really surprised to see a courier standing at the door with our box so early.

I think it’s a very good device for an office situated on the ground floor (but in reality, it’s practically an underground floor).

Stability of connection, fast delivery, professional support service. We haven’t noticed any problems yet.

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.

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 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.

Reliable, economic, high quality and performance The delivery was delayed for 2 days

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.

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.

Cool thing. I have already recommended it to my neighbors with similar mobile signal problems.

The process of installation was rather challenging for me. I spent nearly an hour but finally, I managed to do it on my own.

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.

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!

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...

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.
