LCD-250C+4G Customer Stories

We needed a gadget for our Claro signal problems and we have found it!

Carlos Hinojos (Ecuador, Quito)

We live in Ecuador, not far from one of the largest its cities called Quito. We are Claro subscribers. In general, we always were quite satisfied with the quality of the mobile services that we received. But there is one very significant problem: our house is located in the area of Claro poor coverage. It means that earlier when we didn’t know about mobile signal repeaters we couldn’t use mobile services at home. Claro poor signal prevented us from staying in touch with our relatives and friends. It was really difficult to go outside each time when we needed to make a call or to send a message. It was crazy! Claro signal problems were a real disaster for our family.

There was no 3G or 4G signal in our house but what is more there was no even GSM signal. We needed to improve all types of signal at once, otherwise there was a serious risk for us to stay without mobile communication with our nearest and dearest.

But thanks to MyAmplifiers, we could find a perfect device called LCD-250C+4G. It is able to improve GSM, 3G and 4G Claro mobile signals. That’s exactly want we needed. After we installed our mobile signal booster, we really understood how excellent mobile connection could be!

Thank you, My Amplifiers! We are really happy that we have managed to find you!

Movistar signal problems are gone! LCD-250C+4G is my best purchase ever!

Alejandro Florin (Peru, Huaraz)

But in our house Movistar poor signal was the only signal that could be caught by our mobile phones (and sometimes there was no signal at all). We couldn’t make calls, we couldn’t receive them, the same was true about messages and data exchange. For several years we were trying to tolerate with our Movistar signal problems but then it became obvious that we couldn’t bear them anymore. Of course, sometimes it was possible to postpone communication with our friends, for example, but we didn’t want to tolerate with a lack of opportunity to stay in touch with our elderly parents who live rather far away and may need our help.

When we were discussing with our friends our desire to find a solution for Movistar poor coverage, one our friend mentioned that he had heard something about mobile signal boosters that could be installed in buildings with poor mobile signal coverage with a view to improve the quality of signal. We found several companies offering these devices, but we liked MyAmplifiers and its terms most of all. Now we are using our LCD-250C+4G at home and we don’t have any problems with Movistar GSM, 3G and 4G signals anymore.

We've managed to find a cellular network booster for our Claro signal problems

Alex Lince (Colombia, Tunja)

When I first contacted MyAmplifiers and told their manager I had serious Claro signal problems, we figured out together what could the source of the problem be, and the manager offered me the cellular network booster that would fit my needs (and I needed to amplify GSM, 3G and 4G signal for all my family members and their devices). I honestly didn’t think it was possible, but it turned out they have models that are able to do that. After I made a purchase, it arrived in four days, which really surprised me, because I was expecting to wait for it for weeks, as it usually happens with online sellers. And after that I easily installed the cellular network booster by myself, following the user guide they put into the package: I put the outside antenna close to the rooftop of my cottage and connected it all with a couple of wires. It was really easy and even kind of fun – who doesn’t like to feel like a super-engineer? And after that my Claro poor signal was gone forever. I haven’t experienced any issues ever since, and my family is enjoying fast and reliable connection 24/7. We can make calls without going upstairs or outside, we can use the internet anywhere in our house, including bathrooms, and no matter how many devices we use, the signal isn’t getting weaker. I definitely recommend MyAmplifiers to everyone with Claro signal issues!

Maybe you know that in our country we have serious problems with mobile connection. Nevertheless, it doesn’t mean that we do not have businesses and that there are no offices. To have a good connection if you have a company is a must. That’s why I’ve bought this booster for my office. The sales volumes have increased. I am not joking.

I haven’t expected that I will write a review one day (as a rule, I never do it). But I am very impressed.

Thanks for an amazing support service. I even couldn’t expect that today there are such managers who are REALLY ready to help you. The recommendations from the managers helped me greatly to make a choice.
Excellent device, excellent service.

Purchased Nikrans LCD-250C+4G
I was pleasantly surprised to receive my booster just in 4 or 5 business days after I placed an order. The price is absolutely fair and I haven’t seen any lower prices for the devices with the same functionality, capacities and coverage area.

Purchased Nikrans LCD-250C+4G
That’s an awesome repeater for our flat. We bought it together with my roommate and now I am thinking about buying something similar for my parents.
Quick delivery, convenient payment methods. Though the price is good, I wish it were lower:(

Purchased Nikrans LCD-250C+4G
This amplifier turned out to be beyond my expectations. You can install and practically forget about its existence. The installation was a little bit challenging for me just because I don’t like reading manuals. Nevertheless, in general, it is simple.
Canada, Verified Buyer
Purchased Nikrans LCD-250C+4G
The design of the booster, as for me, is quite strange. I think it would be better if all the elements were white or black. However, as for functioning and signal strengthening, everything is fine.
Mexico, Verified Buyer
Purchased Nikrans LCD-250C+4G
Thanks for this booster. We are enjoying the capacities of LCD-250C+4G in our office and now I think that I should consider a variant of buying it for my house as due to weather conditions and infrastructural peculiarities quite often the signal is a disaster. But all these external factors do not represent any obstacles for a booster.
Tricky installation for me
Brazil, Verified Buyer
Purchased Nikrans LCD-250C+4G
My daughter likes taking online courses and our awful connection at home used to disappoint her. So, we decided to improve this situation. A booster seemed to be a good variant. Many thanks for such a quick delivery to our country. We didn’t expect and highly appreciate it!

Purchased Nikrans LCD-250C+4G
My report for the week with the new Phones booster :) Well, during the week my positive opinion about LCD-250C+4G has only consolidated. This model is durable and of good quality. Most of all, I was afraid to choose the wrong model with smaller coverage. Thanks goodness, my fears are over :)
if you hesitate about what repeater you need, has Helper system to find out which one suits your cell provider. Besides, they have detailed description of the device and competent support. the farther from the booster, the worse gsm reception is, so I wish I bought the one with larger coverage.
Venezuela, Verified Buyer
Purchased Nikrans LCD-250C+4G
Thanks! I like this device! I install it in our house. The house is not very large that’s why the improved signal reaches all the rooms. I am very happy that I bought it.
