NS-300GW Customer Stories

That´s how I managed to boost cell phones signal Ethiotelecom! I am happy!

Habte Wendimu (Ethiopia)

In my case I am speaking about how I could boost cell phones signal Ethiotelecom. Though usually I could use my mobile services without any problems, there was one very significant exception from this rule. I had Ethiotelecom poor signal in my house. I had problems not only with mobile internet (which is a very well-known problem for people in our country) but also with simple GSM calls.

Sometimes, being at home, I felt really lonely as nobody could reach me. And I also couldn’t contact anybody. But I can say that I was lucky as I found MyAmplifiers team that works for those who need to boost cell phones signal in some concrete locations. So, I decided to try.MyAmplifiers company has a great website that I really like very much. Here I read dozens of useful articles and clients’ reviews and testimonials. In the online catalogue I managed to find quite a lot of mobile boosters that can work in my country and there were several variants for Ethiotelecom subscribers. With the help of MyAmplifiers customer support manager I opted for NS-300GW that met all my requirements. I made an order online and rather quickly I received my booster. And I really see the difference! I have never thought that it is sooooo comfortable to have excellent mobile connection at home (as I have never had it before)!

I could successfully boost mobile signal in house. Zain signal problems are gone! Hurray!

Ahnaf Naqawi (Jordan, As-Salt)

Firstly, I have to mention MyAmplifiers website. I was able to find exactly what I need in only a minute, thanks to the simple and colorful interface. But then I found out that there are a few signal boosters that meet my requests. I decided to ask a professional for advice and that was such a great experience! The person from customer support never kept me waiting and provided all the information I needed, but without additional ‘you can also buy this and this…’.

Zain signal problems have been an issue for me for a couple of years already, so I just couldn’t believe that I would boost mobile signal in house so fast. The time has finally come to say goodbye to Zain poor signal! But I must admit that it wasn’t really the operator’s fault. I mean, Zain poor coverage is not an issue. I guess the landscape was the problem or something of the kind…

Well, that doesn’t really matter, because my signal booster eliminated all Zain signal issues for good!

I have had it for a month already and it has been working and doing the job perfectly well. What surprised me was the fact that the whole installation process took me only 10-15 minutes. And only seconds after I turned the device on, it actually started to boost mobile signal in house! My GSM and Internet were finally flawless. I surely do recommend MyAmplifiers to anyone who is experiencing the same problems that I have. It is the best choice on the market!

The results of installing the repeater have been outstanding

Jacques van Biesen (Spain, Andalucía)

We live in the mountains in Andalucía, Spain without any cellphone coverage at all, either in the house or on the terrace. It was really impossible to contact with someone by phone dut to Yoigo signal problems and all that complicated our life a lot. However, I found that I had a 2-3 bar signal on the roof of the house (one level bungalow). That signal probably went from a base station but of course was too low to catch it by a cell phone. I was really frustrated until I found a solution. With the NS-300GW, we now have 5 bar coverage throughout the house and 3-4 bar coverage on the swimming pool terrace. The results of installing the NS-300GW have been both surprising and outstanding.

I have already recommended cell phone booster to other people with the same problem. Trust me, if you live in a zone with Yoigo poor signal (like in the mountains, for example) this is an easy solution! I was actually very surprised when I was able to install the NS-300GW by myself. It’s also very easy to use.

Purchased Nikrans NS-300GW
I am currently living on a campus of a university not far from the mountains. The fast half a year my friends and I didn’t have any problems with 3g connection or GSM but a couple months ago we began suffering from a bad signal. So, my friend’s parents brought us the model NS-300 GW and a special man installed it for us within two hours. I saw that a set had a repeater, two antennas, and a power supply. We were amused when the signal became great not only in our room but the following 3 rooms found out the same thing. It’s great that it can work extensively.

Norway, Verified Buyer
Purchased Nikrans NS-300GW
The device looks very modern. At first, I wanted to buy another model that was even more expensive but Alice (sales manager) helped us to choose this repeater as it also perfectly met our requirements but was a little bit cheaper. Thank you for your honesty!
Netherlands, Verified Buyer
Purchased Nikrans NS-300GW
To tell the truth, when we ordered the device, I didn’t have any special expectations as I really didn’t know what to expect. However, now I am in love with it. It’s fully worth the entire amount that we paid for it and I think that if somebody asks me about this booster, I will sincerely recommend it.
Latvia, Verified Buyer
Purchased Nikrans NS-300GW
I am completely fond of the booster. It fulfills all promised functions I read on the official website of your company. I was slightly disappointed with paid delivery to my country. However, 20 euro for this is not the sum of money against the quality of 3g connection and GSM and I was delivered the amplifier directly to my apartment. Recommend!
Malta, Verified Buyer
Purchased Nikrans NS-300GW
I use the NS-300 GW model for my office and didn’t notice the negative sides of the booster. It totally helps us with a good connection and I am not going to purchase a new one. I am really grateful to the support team which assisted me in choosing and sent an amplifier after 2 days I ordered it. Very quickly!
Finland, Verified Buyer
Purchased Nikrans NS-300GW
When I just installed the booster, I was ready to return it as it didn’t work. But the problem was that I forgot to switch it on. Yeah, things happen:) So, be very attentive, guys. The booster is cool!
Uganda, Verified Buyer
Purchased Nikrans NS-300GW
We work in a VERY rural environment in Uganda and purchased three units in all. The purchase process was quite smooth. in one location we put in the Nikrans NS300 and in the the other two locations we put in the 450 model which work great. After a short time the NS300 simply stopped working. So upon our return home I made contact with Julia who was very understanding and quite professional. The unit was eventually diagnosed and replaced without fuss. I reply appreciate the professionalism at MyAmplifiers and plan to purchase other units in the future.
