NS500-GSM+4G-PRO Customer Stories

Vodafone booster box for signal problems interfering wit business communication.

Tamás Ecseczki (Hungary, Budapest)

At that time we were only interested in the financial side of the question and didn’t pay much attention to the fact that the premises were located on the underground floor. Just a few days later we noticed that we couldn’t make phone calls from the office and the internet connection there was unbearably slow. The reason for these inconveniences was Vodafone signal problems. At that point we clearly understood that we had to do something to change the situation and to improve Vodafone poor coverage in the office. On the internet we found information about Vodafone booster box and we decided to buy one.

We chose Nikrans NS500-GSM+4G PRO booster. The Vodafone booster box has an indoor coverage of about 500 m2 which is enough for our office. It supports 800 and 2600 MHz frequencies for 4G Internet and 900 MHz for calls, so it is fully compatible with Vodafone mobile operator. Immediately after the installation we felt the difference. Vodafone signal issues disappeared and we started to enjoy perfect mobile reception, our internet connection became much better. We are fully satisfied with the result and we will advise GSM 4G signal boosters to people looking for ways of improving Vodafone poor reception.

Africell signal problems are completely solved thanks to home mobile signal booster!

Marvin Dhaira (Uganda, Kampala)

If I had known what miracles this wonderful device can do I would have bought it much earlier. This is my first experience in using a home mobile signal booster and I’m fully satisfied with my choice. I live in a private house on the outskirts of Kampala where unfortunately Africell signal problems have become a very frequent phenomenon. Each time I needed to make a call I had to go out of my house to find a place where Africell signal was good enough. Needless to say, how irritated I got whenever my internet connection suffered from Africell poor reception. From day to day I was getting more and more nervous. You know these constant disconnections and endless drops really got on my nerves. Then I decided to ask my neighbors how they were coping with Africell signal issues. They told me that they had installed Africell home mobile signal booster and Africell poor coverage is no longer a trouble for them. So, I made up my mind to do the same thing.

I visited MyAmplifiers but the number of devices was so large that I couldn’t choose the one which was suitable for my house, therefore I got in contact with the support team. The professionals advised me to choose a 4G booster. The device improves GSM connection for calls as well as 4G for mobile internet.

My data speeds were terrible

Ian McBain (Desingy, France)

I live in a French farmhouse with very thick stone walls. As a result, the Prixtel 4G signal strength inside the house was zero or one bar only, -100dBm to -109dBm. Data speeds were terrible. I also had a very slow fixed broadband speed of 0.5Mbps or less.

I was searching on the internet for a 4G signal amplifier and found the MyAmplifiers website. I used the live web chat helpline and got immediate advice on which amplifier I needed. I ordered the Any Tone AT4000W which arrived within a few days. While this amplifier certainly worked, unfortunately, it was not powerful enough for the size of my house. Coverage was not good enough to improve the network signal throughout the house.

So I contacted Julia in MyAmplifiers Sales Team and she recommended the NS500-GSM+4G-PRO which she offered at a discount. So I returned the AT4000W and ordered the NS500-GSM+4G-PRO instead. It also arrived quickly.

The NS500-GSM+4G-PRO is fantastic. The coverage area is 500 sq m and it provides 3 or 4 bar coverage in every room of my house. It worked immediately, and all devices in the house benefited from the super strong signal.

I would also add that the cables provided to connect the external antenna to the amplifier and then the amplifier to the internal antenna are thick and black and so are not so pretty in the house!! Hard to hide them, but it depends on where you can install the amplifier. Also, it is necessary to somehow make a large hole from the inside of your house to the outside to pass the cable through. This is not easy depending on your situation.

I highly recommend MyAmplifiers and if you choose the right amplifier they really do make a huge difference. I now have -85 dBm signal strength and internet speed of 4 to 5Mbps!! Fantastic!!

I live way down in a valley way out in the boondocks. I was lucky if I got one bar on my cell phone. Calls dropped all the time. I never in my life thought it would get any better. I bought this signal amplifier, and now I have 4G and four to five bars consistently. Overall, it works good, no more dropped calls or bad reception inside. I am truly I would recommend it.

This booster is something we were dreaming about for ages!
Very stable connection without interruptions. The manual (and most of the information on the website) is in English and my English is far from being perfect.

This one booster can improve different types of signal and that’s the main benefit for me. It is cool that there is no need to buy a separate device for each type of signal.

Usually I don´t shop in online stores. But I decided to try with 4G booster at because my best friend had already ordered from you and was satisfied with everything. I risked and never regretted this, because your staff really helped me. I don´t know anyhting about 4g and repeaters, I just described my situation to the manager and she recommended me this model that works perfectly now! Thanks!

After using this device for a little over 3 months now I can say this works. We live in an area with little to no cell reception, our home also has a metal roof. I work in IT and require the internet any time of day. So it was complete trash without this amplifier. This thing allows us to be inside and talk&text and have the hotspot connected 24/7 to the net.

My house is on the edge of mobile phone coverage. The house has a metal roof. I had to stand next to a window on one side of the house to use my cell phone. The rest of the house had no service at all. I bought this 4g signal amplifier. It took half an hour to install. I mounted the outside antenna on a pole on the roof where I received best signal. I’m very happy with the purchase.

In general, I am very happy about my purchase. The device arrived very quickly, it was well-packed and everything was perfect. But the installation was not very easy for me. I needed to ask my friend to help me. Yes, in the box I found a nice manual but for me, it was still a disaster. Nevertheless, my friend managed to install it within an hour time. NS500-GSM+4G-PRO is a very powerful device: if earlier my phone couldn't even catch the 4G signal of my operator when I was at home, now I always have 4 or even 5 bars.

NS500-GSM+4G-PRO is the best device I’ve ever seen. And yes, it’s not the first one in my life. As I live and work in the rural area, the issue of poor mobile connection is very pressing for me (and it has always been so). Some years ago I ordered another model of this device on another website, at first I was satisfied with it but now, when I can compare it with my new one, I realize that NS500-GSM+4G-PRO is much better. Moreover, some of my neighbors also have boosters and NS500-GSM+4G-PRO is still a winner. The device is able to amplify my GSM signal and my mobile internet connection simultaneously. And what is more important: its work is absolutely stable.

A year ago, we bought a new house. And of course, we were unbelievably happy. For us it was a very important event. The house is located in a beautiful valley surrounded by mountains. Everything was perfect but it was one detail that spoilt everything: our mobile signal was soooo poor that we couldn't’ even make calls. On the first floor, it was possible at least to catch a signal but on the ground floor...there was no chance to get connected. We realized that something should be done. We tried to reach our mobile operator with an inquiry to build a new cell tower in our neighborhood but it turned out that due to some infrastructural issues it was prohibited. So, we decided to change the situation on our own. Thank God, that at least at work I had a perfect internet connection and I managed to find this website. Now our problems with mobile signals (4G and GSM) at home are in the past. Thanks, guys, for this perfect device.

To tell the truth, I am an experienced online buyer, so it was rather challenging for me to order this booster, at least at first, it seemed to me that it would be challenging. But I decided to contact a support team in order to avoid any silly mistakes and you know, the service was perfect. A very nice and polite girl (sorry, I’ve forgotten the name) explained to me every step that I should make to place an order and to make the payment. Thank you for such enormous attention to me, for the fast delivery and for my cool booster (my LTE signal increased from 1 bar to 5 bars, isn’t it a great result?)

I am a subscriber of Orange mobile services and I never even thought that one day I would face any problems with my mobile signal. But it happened in my new office. I noticed that I couldn’t check my mobile apps on the first day at my new job but I decided that it may have happened occasionally. In the evening at home everything was okay. Nevertheless, on the second and third days, the situation was just the same. I asked my co-workers about the situation with their connection and it turned out that they were also suffering from poor connection though they all are subscribers of different operators. It became obvious that the problem was a result of the influence of some external factors.

All together we started to look for a solution and a variant to buy a booster seemed to be a good idea for us. So, we have been using NS500-GSM+4G-PRO for three months and we are 100% satisfied.

P.S. The coverage is just enough for us but our office is comparatively small.

I bought this device for my parents as I was fed up with their unstable connection (sometimes I needed to spend 2 or 3 hours at least to reach them just because of their mobile signal problems). When I was choosing a model for them, NS500-GSM+4G-PRO seemed to be a good variant as it is able to boost all types of signal. Now my dad even watches some YouTube videos on his phone:)

I’ve recently moved to a cabin in the mountains. I was lucky to get one or two bars and little to no signal inside. After installing the signal booster, I consistently get 3 bars of 4G signal inside. The device and accessories seem to be of good quality. Installation and setup was extremely easy. I found a map of the nearest towers online. I would definitely recommend this product.

The booster itself s great but I was disappointed to see that it was delivered in the damaged box. I believe that it could have been the fault of the courier service. Nevertheless, the device wasn’t damaged and it works really well.

Without any doubts this is one of my best purchases! Covers 2 floors of our cottage y supplies perfect 4g connection and calls. I´d recommend this booster to the young people who actively use 3g Internet and live in the countryside where the signal is low.
I see many advantages in the ordered device, but the most important one is PERFECT 4g throughout the house. There was the delay of delivery, but having got such a great result I see those inconveniences so unsignificant

I bought this device for my daughter’s new 3-story home. She was able to get good reception on the 3rd floor, spotty reception on the second floor and no reception on the first floor. After installing the device on the 3rd floor, she is able to call me right away on the 1st floor and the call quality was excellent. She now gets 2-3 bars and perfect 4G Internet where she was getting none, so this device works as advertised.
