How it works

While the outdoor antenna should be mounted on the roof of the building where you need to improve the signal, the indoor antenna as well as the phone signal booster box itself should be mounted inside the building.

The main rule is to fix your indoor antenna not closer than at a distance of 5 m from the external antenna, otherwise, they will interfere each other. Moreover, to achieve the best performance of this indoor antenna (it is responsible for spreading the amplified signal), you need to find a place in the middle of the area that you wish to cover with the improved signal. To place it at least at a 2-meter height over the ground is a must.

Satisfied with the purchase

I bought it to use it at work, in a coffee shop. Our visitors had poor wifi signal before, which wasn’t the fault of the operator, and our router wasn’t to blame as well. Now poor interrupting signal isn’t a problem at our coffee shop anymore, and we all can have stable internet and clear phone calls. The signal got much better for both the staff and the clients, and everybody’s really happy about it.

Hi, Taslima! Good to know that your clients, as well as the staff, can have great signal now. We’re always happy to help! Best wishes, Support team.

Makes my grandparents happy

My grandparents had really poor signal at their summer cottage, and they always thought it was normal to have that kind of reception while being out of town, so they didn’t try to do anything about it. When I came to visit them, I had to walk around the house and stand near windows to get adequate reception on my cell phone, and I didn’t even mention the internet quality! That was horrible, and I decided to order them a signal repeater as a gift. They absolutely loved it! It works very well, amplifies the signal in their house, and even though they don’t use the internet too much, their guests appreciate it a lot.

Hi, Akash! It’s good to know that your grandparents and their guests, including you, are so happy with the signal now! Best regards, Support team.

Makes a major difference in reception

I tried a different brand from a different store once, and it didn’t work as well as I expected (and as promised), so I had to return it and look for other options. Then I bought this repeater after reading a lot of forums and reviews, and everything works smoothly now, even though I was already pretty skeptical about it all. I’ve got a decent signal outside the house, but it kept struggling inside, lowering my data speeds, and I got really tired of it. When I installed this repeater, I was very surprised with how noticeable the difference in reception turned out to be. It’s now a really rare occasion to not have all of the reception bars on my phone, and the internet speed is outstanding. It literally took me half an hour to install everything and to make it work. This repeater really rocks!

Hello, Timothy! Our team is happy to know that everything worked out for you. Thank you for your review! Best regards, Support team.

Case Studies

Phil Broad, Manchester

Very helpful service in choosing a booster.

One day I typed in “signal boosters” quite hopelessly, and Mobile-signal-boosters.co.uk website caught my attention because of the detailed, but still very understandable information they had. Out of curiosity, I asked their customer support, what model could they recommend to me, and was very pleasantly surprised to find out that the model they offered to me was really affordable even in my case, without any fine prints.

Norman Wheely, Aylesbury

My struggle with poor mobile signal.

I’m a musician who needs a good stable 3G internet in the studio all the time. The building where I rent it is located in the suburbs, but my The People’s Operator reception, despite my expectations, was extremely poor inside the building, which was an old factory rebuilt for rental spaces. The reason behind it were the thick walls of the building. I came to a conclusion that I need some device to help me solve that.

Edison Cuthbert, Wakefield

Thanks to this store I can enjoy an excellent mobile signal!

The manager of Mobile-signal-boosters.co.uk was the one who persuaded me that my problem can be solved and helped me choose the suitable repeater model. I also received all the answers to all the questions that I had about signal repeaters, even the most obvious ones. The manager was quick, polite and very helpful. I’m really happy with my purchase from Mobile-signal-boosters.co.uk and enjoy a comfortable life with good GSM and 4G signals.
