LCD-250C+3G+4G Customer Stories

AT&T signal problems in our house vanished with the help of AT&T mobile range booster for home

Gordon Strome (USA, Idaho)

I found MyAmplifiers’ website online and was pleasantly surprised by their customer-friendly service. I told them about our AT&T poor signal and asked for an advice, and the manager said we should go for the mobile range booster for home LCD-250C+3G+4G. I also liked their warranty offers and an option to return the device with a refund, so I discussed that with my wife and we decided to buy it. And – no more AT&T signal problems ever since we turned it on! Our children are happy with their internet speed, they can study and then use internet for their own needs without any troubles, and everyone from our family can use their gadgets at the same time without losing connection. We absolutely love that.

The signal repeater doesn’t make any noises, it doesn’t heat up the air in the room, the mobile range booster for home looks nice and compact and can cover the whole area of our house, and even the basement and the garage. We can also enjoy good internet connection in the terrace, and overall it’s even better that we could expect. AT&T poor coverage is not a problem for any of us anymore, and all thanks to MyAmplifiers company and their amazing team!

LCD-250C+3G+4G is an absolutely wonderful device to boost cell phone signal strength at home

Carlos Yanez (Mexico, Cedral)

When my neighbor came to visit me and to say “hello”, he told me that he had already won his battle with Weex signal problems. I was impressed :) The solution to boost cell phone signal strength was found so quickly. My neighbor showed me MyAmplifiers site and I understood that, yes, just in a couple of days my life without mobile communication would come to an end. It sounded great!

Following his recommendations, I contacted MyAmplifiers customer support team and together with the manager made my choice. I ordered LCD-250C+3G+4G. I liked its price, coverage and capacities. This signal booster is able to boost cell phone signal strength of Weex GSM, 3G and 4G connection. Something unbelievable!

Thank you, MyAmplifiers team! You are really amazing! It took less than a week for my booster to arrive at my door. I installed it just immediately and couldn’t believe my eyes when I saw that my mobile phone began showing the strongest signal. Thank you once again, guys, for your high quality services and devices! I wish you good luck and hope that your business will be thriving!

Now we don’t have any Claro or Digicel or Movistar signal problems in communication with our clients!

Brian Vasquez (Panama, Panama City)

I am a subscriber of Claro mobile services provider and as a rule I don’t have any Claro mobile signal problems. But in our new office Claro poor signal didn’t give me a chance to receive calls or browse the net. My co-worker suffered from Digicel signal issues but he could at least use GSM network services. Movistar signal problems were not so serious and appeared only from time to time.

Nevertheless, it was rather difficult to work with clients when we all were deprived of an opportunity to use mobile services and to communicate with our clients in a proper way.

To tell the truth, earlier I didn’t know that I could improve my bad mobile signal in the area of Claro poor coverage. But one of our co-workers had already overcome Claro mobile signal issues at home and when we faced with such difficulties in the office he told us about MyAmplifiers.

We had really a difficult task as we needed to find a mobile signal booster that is able to boost signals of a number of mobile operators. Moreover, it was necessary to improve not only 3G signal but also GSM. Nevertheless, we found such a device – LCD-250C+3G+4G! It is amazing!
