NS-20K-Voice, 3G & 4G Customer Stories

That's how I could boost your cell signal. Decent solution to my Digicel signal problems.

Gabriel Urzaiz (Venezuela, Choroni)

I bought the booster NIKRANS NS-20K-Voice, 3G & 4G to boost your cell signal Digicel in my villa situated on the outskirts of the coastal mountain range in the village of Choroni, located in Aragua, Venezuela. This place is extremely popular with tourists due to Choroni beach. So quite often my villa is rented by them. My visitors often used to complain about Digicel signal problems and as you can guess their stay wasn’t as much pleasant as they would like it to be. So I bought and installed Nikrans repeater with a view to satisfy my customers.

The model I have chosen is suitable for my villa as it is able to boost Digicel poor coverage on the area up to 20000 ft2. And it is fully compatible with Digicel network. The shipping was very fast and I am delighted with the kit as it includes everything necessary for the set up and for the effective work of the device. Actually I managed to install the booster on my own using the manual included in the kit and it took me less than an hour. The device started to boost your cell signal Digicel as soon as I plugged it in. So far there have been no Digicel signal issues in the villa, the booster works without interruptions and errors.

Get the best cell phone reception as I've done!

Miguel Enache (Honduras, Gualjoco)

Our story is quite usual and I think that 85% of all owners of mobile signal boosters have faced with similar problems. Living in a rural area, we used to suffer from Tigo poor coverage. And sometimes inside the building it was absolutely impossible to enjoy mobile services. If we needed to make a call, we needed to go outdoors and try to catch sufficient mobile signal.

Yes, Tigo poor signal at home was becoming more and more irritating. And the best idea that came to my mind was to ask Google. I began searching for any available ways to get the best cell phone reception Tigo and rather quickly I found this web site. Initially, all these devices seemed rather complicated for me and I really didn’t know whether I would manage to use it. But then I read practically all the information published on the site and understood that all my fears were rather silly. Without any problems I chose the most appropriate variant for my family (it was MA-500C that can boost GSM and 3G Tigo signals) and made an order.

Dear friends, just believe me this device has changed my understanding of mobile communication. Only thanks to my mobile signal booster we managed to get the best cell phone reception and have understood how amazing mobile communication could be!

Virgin Mobile signal problems stopped straight away after installing the phone booster for home.

Isabella Teres (Colombia, Sopó)

Many people in Colombia complain about poor mobile signal coverage in some remote or rural areas. And I also appeared among those who were enforced to complain. Due to Virgin Mobile poor coverage (and namely, Virgin Mobile GSM and 3G poor signals) in our neighborhood, I couldn’t use mobile services at home. At the moment I don’t work, I stay at home with my small children, so, I really need to have good mobile connection. It is really important for me and for the whole our family.

Virgin Mobile signal issues were unbearable, I even couldn’t make a call, without even mentioning usage of mobile internet services. The more I tried to get accustomed to Virgin Mobile signal problems, the more I understood that I wouldn’t manage to do it. My husband discussed these problems with his colleagues and they advised him to visit MyAmplifiers web site.

So, one day I visited MyAmplifiers page and understood that a phone booster for home can be exactly the tool to overcome mobile signal issues that we were looking for. We had a difficult task for our potential booster, as I wanted to improve both GSM and 3G signals. Nevertheless, there was such a device! MA-500C phone booster for home became my choice and irreplaceable helper! Now mobile communication is not a problem for me.

Sorry, I am not very good at writing reviews. Nevertheless, I want to recommend this booster. It functions just perfectly. Now we have an excellent 3G connection. Unfortunately, our operator does not provide us with a 4G signal that’s why I can’t tell you whether this device is able to boost a 4G signal (but I am sure that it is).

It’s such an amazing feeling when you want to make a call and you can make a call! Unfortunately, earlier, we could only dream about it. Now, it’s not a dream anymore, it’s a reality that we can enjoy. When we moved to a beautiful house located on the river bank far away from the noise of the city, we couldn’t even imagine that we would face any problems with our cell connection. Nevertheless, it happened. My wife works from home that’s why it was crucial for us to improve the signal. Especially, she asked me to find a solution to amplify our LTE signal as the main part of her interaction with clients is organized via the internet. I am not a magician but I’ve managed to make her dream come true;) Thank you! This booster is of great use for us.

The first thing that I want to do now is to say thank you to the nice girls that work in the support team. They really helped me a lot. I am really grateful for your professional help and your attention! When I received the order needed to ask my boyfriend with the installation, nevertheless, the usage of the device is absolutely easy (you don’t need to do anything special, just to enjoy). Thank you! I’ve already told all my friends about this top-notch device.

I’ve bought this device for our office but now I am considering an option to buy a similar booster for my home. Unfortunately, in our country, there are still a lot of areas with bad coverage. But I am happy that I’ve found this website where it is possible to order reliable boosters.

Good model for reasonable price - that's my first impression. I can finally get 4 or 5 bar signal strength. I liked that the installation took only an hour, it was very easy. The only condition is to read the manual beforehand. We found a pole and tied an outside antenna to it so that the whole construction was higher, I think it works as the nearest mobile station is 20 km away from the house. Now I’ve read here that people often have problems with lightings and I think I’ll put a lightning rod next to the antenna (don’t want my booster to break down soon). I’d advise everybody who has poor signal to buy a anytone repeater, it works great!
just the ones I’ve written here – reasonable price, easy installation, good performance, clear manual, etc. It’s also nice to realize that the tool lowers the amount of radiation. lightning may be serious danger for the mobile booster.

Though it’s the first booster in my life, I think it’s the best one! The only negative aspect that I can mention is that the box of my booster was a little bit damaged. But the device itself didn’t have any damages and it functions just perfectly.

Support of numerous simultaneous connections, easy installation, reasonable price. I don’t know the reasons but the device took 3 weeks, I hoped to receive it faster.

I bought this booster 5 months ago but decided to write a review only now. During these 5 months, I didn’t have any problems with my NS-20K-Voice, 3G & 4G PRO. Its coverage is enough to ensure a stable connection in a 3-story office building. Every day at least 10-15 people enjoy the amplified signal without any interruptions. As for me, it’s not a very cheap device for private buyers but for a company, it’s absolutely affordable.

For many years we were obliged to suffer from a terrible mobile connection. Nevertheless, finally, I understood that it was necessary to do anything about it. Thank God, today, on the internet you can find anything you want. The same happened when I tried to find the answer to the question of how it’s possible to improve the quality of the signal at home. Yes, I’ve found this website via google. At first, this idea to install an additional device seemed to me rather strange but then I studied dozens of reviews and understood that it really makes sense. So, together with my parents, we took a decision to try. Though the device is far not the cheapest one, we understood that we were so tired of problems with our cell connection that we were ready for experiments. We received our order in less than a week after placing an order. After we installed and switched it on, we realized that it was a brilliant idea to install it, the quality of our signal was improved just immediately.

The amplified signals are very stable. We didn’t expect to have such a powerful connection in our area as previously the signal quality was absolutely awful. Thank you for offering devices with such wide coverage so that people who want to install a repeater in a large building do not need to buy two or three separate boosters.

I am 100% satisfied with my cellular amplifier. Ana S helped me and explained what model I need and why. Thanks for great customer service – highly recommend you!
our amplifier-extender gives additional 3 bars on average, when the weather is terrible it adds 2 but that is enough for us.

A very good option for an office building.
It works with all the mobile operators that provide services in our country, the signal is still stable even when dozens of smartphones are located in its coverage zone.
