NS-12K-Voice, 3G & 4G Customer Stories

CooTel signal problems used to deprive me of good 3G connection and manages to boost your phone signal.

Brian Distler (Nicaragua, Jinotega)

I moved to a small apartment in a big high-rise building and figured out that I was having CooTel poor coverage inside. I have a different internet provider, so I have no problems with internet, but anyone who tries to call me on the call phone complained that I was always out of reach, my phone was outside the coverage zone, and when they could call me, they could hear me very poorly and the calls were always dropping because of CooTel signal issues. That was very annoying, and I wanted to boost your phone signal, so I started looking for options. Changing the operator wasn’t easy and cheap, changing the apartment was very stupid, so I came up with another idea and searched for a signal amplifier. And I found one that could boost your phone signal.

When the amplifier arrived, I put together all the parts very easily, placed the outer antenna outside my window, connected it to the booster box and put it in my living room, and it all worked out. I started receiving high-quality calls, I could hear everyone perfectly and those who called me could hear me very well too. CooTel poor signal was gone and forgotten, and now, thanks to MyAmplifiers store and the manager who helped me so much, I can enjoy modern life and use my phone as much as I want to.

An irreplaceable device to improve cellular signal GoTalk.

Sam Weller (Australia, Bathurst)

When I moved to a new flat and saw that GoTalk poor coverage would become a real obstacle for me, I was ready to change the flat, really. But then I understood that nobody could guarantee that I wouldn’t face with some GoTalk signal issues in my new flat No.2. So, I decided to try to improve cellular signal. By, the way I had GoTalk signal problems only with 3G network signal, with GSM signal everything was okay.

Thanks to MyAmplifiers, this variant was successfully found and GoTalk 3G poor signal was successfully improved. On MyAmplifiers website, I managed to find NS-12K-Voice, 3G & 4G signal booster that became an irreplaceable device for my family. On the website I could find a lot of really useful and interesting information about these devices. I carefully examined all the terms and conditions of payment and delivery. And I think that all the points are quite appropriate for the majority of people. Moreover, the company’s customer support team works just perfectly!

Thank you, MyAmplifiers, you are really great! I like the quality of my booster and its effectiveness to improve cellular signal. I really can recommend it to those who have some similar problems with mobile signal in their houses or flats.

Our Móvil signal problems are terminated! The best cell booster for home at Myamplifiers!

Fernando Lietor (Panama, Anton Valley)

We live in a small town in Panama and, unfortunately, Móvil poor coverage is a common problem for the entire neighborhood. If outdoors the signal is rather sufficient, indoors Móvil poor signal (if not boosted) won’t give you a chance to make a call or to send an email. You know, we are even accustomed to mobile signal problems and a lot of people in our country are even ready to tolerate with Móvil signal problems. We also used to be among them. But when our daughter grew up and moved to another town, we decided that we needed to improve our poor mobile signal to stay in touch with her.

That’s why we began looking for something that could help us on the internet. We found MyAmplifiers site and were really surprised to see that there are so many different devices that are able to deal with various types of mobile signal problems. We chose the best cell booster for home NS-12K-Voice, 3G & 4G that is designed to improve Móvil GSM and 3G signals in Panama.

We installed it in our house and now we can use excellent mobile services. Moreover, we have already recommended your web site and this best cell booster for home to all our friends who have similar problems (some of them are suffering from Móvil poor coverage, others are subscribers of other mobile operators but also have some signal issues).

I ordered NS-12K-Voice, 3G & 4G PRO three months ago and I am fully satisfied with my choice. Earlier I hardly ever could make a call, now I always have 4-5 bars and enjoy the stable connection. I’ve already recommended this device to all my neighbors who have similar problems. I want to express my special gratitude to Alex who provided me with excellent professional advice regarding the installation process. So, if you also have any doubts on how to install it, I think that the managers will help you without any problems;)

A very helpful device to install in your office if you have similar signal issues that we used to suffer from.
Perfect functioning. The installation process may become a challenge for a girl who has no understanding of all these tech things (and I am such a girl!).

This website was a cool discovery for us. We even didn’t expect that it would be so easy to buy a device from another country and get it so quickly delivered. Though I am not a very experienced e-shopper, it wasn’t difficult for me to understand how to place an order and how to pay.
The device functions so well! No interruptions in connection at all.

Thanks for this awesome device! I work from home, so, it’ extremely important for me to have a stable internet connection. Without this booster, it was a real problem for me to check my email box from my smartphone. Now I even can make video calls!
Mexico, Verified Buyer
Purchased Nikrans NS-12K-Voice, 3G & 4G
We have installed NS-12K-Voice, 3G & 4G PRO at our office. And it practically saved our business. Maybe it sounds quite strange but our office building is situated in the area that is badly covered by all operators. So, all our employees regardless of their operator were obliged to suffer from an unstable connection. Quite often our clients and partners couldn’t reach us and as a result, we lost a number of contracts. One guy from our team offered to look for a booster and even recommended this website as he had already bought a similar device for his home here. So, we easily managed to find an appropriate model via a search form and placed an order. The device was delivered in two weeks. I think it’s rather fast. After we installed this booster, it was impossible not to notice the difference. Thanks! We are happy.
Argentina, Verified Buyer
Purchased Nikrans NS-12K-Voice, 3G & 4G
It was pure luck that I found this wonderful website! We live in the suburbs of Buenos Aires and as well as many of our neighbors we used to suffer from an awful cell signal. As a result, we couldn’t make and receive calls when we were at home. The last drop was when our 8-year old daughter stayed at home alone and couldn’t call us when she felt sick. So, I decided that I needed to look for a solution. At first, I thought that it could be enough just to buy more powerful smartphones but then my friend explained to me that it wouldn’t help us. He recommended me to search for a reliable booster. NS-12K-Voice, 3G & 4G PRO seemed to be a cool variant and it really turned out to be so. Thanks for this booster! Now we always have a very stable connection at home.

Thanks for your work, guys! I am so happy that today there are companies like yours. Though I am always a little bit afraid to make purchases online, especially when it comes to rather expensive goods like this one, everything was perfect. There were no problems with reaching the team, the managers were always ready to answer all my questions and it made me believe them. So, I ordered a booster and began waiting. Just in 10 days, I received my booster. Thank you, I’ve been using it for 6 weeks and I haven’t regretted buying it.
