How it works

The repeater consists of various parts. The full set which we provide includes NS-300GW dualband booster box, an indoor antenna, an outdoor antenna with 10m cable, and a power supply. In order to improve weak signal you need to catch it with the outdoor antenna, boost it with NS-300GW repeater, transmit it to the indoor antenna and finally catch an improved signal with your cellular phone. Taking into account the stages that the signal goes through before getting to you in an improved condition you should remember that it’s better to locate the outdoor antenna in places with the strongest existing signal from the provider’s masts. Together with this booster model we also offer other dualband solutions for larger, e.g. our best-seller in France NS500 GW dualband amplifier for large areas up to 500m².

Awesome and simple

I bought a vacation home in the country with poor cell signal outside the house and virtually non-existent inside. After reading reviews I decided to try the NS-300GW. The unit arrived on time. Aside from having to drill holes myself to fix the outdoor antenna, overall very easy to install and understand. Remember that the unit takes your outside signal and brings it inside. The quality of the inside reception depends on how good you direct the outdoor antenna. I determined the location of my nearest cell tower and pointed the antenna in that direction. After installation I saw immediate results. My phone was holding 2 bars 4g lte. My mobile unit jumped to 4 signal bars sometimes 3. This device is rather expensive but worth the money.

Dear Bryant, Thank you for a detailed review, we greatly appreciate it. Best regards, Support team.

Beyond impressed

Recently we bought a house by the lake. It’s located far from a cell tower. We might get 1 to 2 bar signal. Since we installed the booster, we keep a 3 to 4 signal, and the internet speed has improved.

Dear Edward, good to know that we could help you. Kindest regards, Support team.

Works great!

We have installed the repeater in the village house. The reception there was far from perfect and now it’s great. The signal is stable for calls and the internet. We used to have another booster which covered a much smaller area, but this one has indoor coverage of 300 m2. Now we have a strong signal even where there was no connection with the previous one. I recommend this product! Delivery took about a week.

Dear Eva, thank you for leaving a review. We are glad to know that you are satisfied with the product. Kindest regards, support team.

Wish we had installed it earlier!

To say that we are impressed would be an understatement. It did the job perfectly! The installation instructions were very clear. The process went fairly quickly and smoothly.

Dear Soren, Thank you for your feedback, it means a lot to us! Best regards, Support team.

Very glad I purchased it

NS-300GW turned out to be an ideal option for me. I’ve been having signal issues since I moved into my own house in the countryside, and it was driving me crazy, but now everything is great, both calls and internet!

Hi Nabiha! We’re very glad that our product helped you sort out all of your signal troubles so well. Best regards, Support team.

In my opinion, the booster costs too much for a dualband device. I have no complaints about its operation and installation, but I wish it cost a bit less.

Hi Richard, thank you for leaving the feedback. We offer the lowest price for this model. Wishing you all the best, sales department.

Haven’t noticed any drawbacks

Strengthens the signal where it is practically nonexistent. I’ve already checked it. The booster really works. The cables are long, and it’s quite convenient if the antenna is not close to the booster box unit. The price is acceptable and doesn’t repel the potential buyer.

Hello Denis, thank you for the feedback. We would be glad to see you at our store again. Best wishes, sales department.

I still haven't found any flaws with this device after having used it for almost three months. The amplifier works fine.

Hi Samuel, thank you for leaving the feedback. Would be glad to see you at our store again. Kindest regards, support team.

Easy installation

I installed the booster myself. The whole process hardly took more than an hour. The installation is easy and understandable as no additional mountings and fixations are needed, all is included in the standard set.

Dear Tom, thanks for the review. We would be glad to see you at our store again. Best regards, support team.

Quality Product

I bought this booster a month ago, and I am satisfied with the purchase. Connecting up the three-part set was rather simple. I recommend trying temporary placement for a while if it is possible to do so, just so you can make sure the signal is the best one you can receive. Everything you likely need is included in the kit. The outside antenna is to be mounted up high and outdoors, but it does not require special skills. Their customer service is remarkable. The instructions that come with the booster are straightforward and clear.

Dear Kevin, Thank you for the feedback, it is very important for us. Kind regards, Support team.

Welcoming Service

I’d like to thank the company for a high quality product and for their welcoming service. The shipping was as promised and it was free. The manager on the phone patiently answered all my questions, even the silliest ones. The product was sent with all the necessary mountings and manuals. You can trust this company!

Dear July, thank you for the review. We are glad to receive your high appreciation. With best wishes, the team of Mobile-signal-booster

Suitable for any network

I needed a booster to amplify reception at the office. I couldn’t find the right one as all the employees use different operators. Fortunately, the manager helped me and advised me to choose NS-300GW. I’m satisfied with the result. Anyone can benefit from the intensified coverage at the office.

Dear Oscar, we are glad to receive your feedback. Thank you for choosing our product. With best wishes, support team.

Works great!!!

I was skeptical at first that this would do any good inside my house. However, after installing the booster, I’ve been very happy with the results. For the first time ever, I was able to make a phone call while being in my living room, instead of going out to the yard.

Dear Seng, thank you for a detailed review. Kind regards, Support team.

This product really works!

I’ve struggled for years with spotty mobile service in my house. Went from not being able to use my phone to clear reception. Now have great signal strength. I would recommend this to friends.

Dear Ekamresh, thank you for your review! Keep enjoying the booster. Best regards, Support team.

Clear up the working frequencies of your operator

I bought it to amplify 1800 Mhz and couldn’t understand why it didn’t work. I called the support team and they told me that this model works for 900 Mhz and 2100 Mhz, so due to the lack of the required frequency, it was a completely useless purchase. Fortunately, I managed to return it and bought NS-300GD instead.

Dear Marco, thank you for the review. Please, feel free to contact us in case you need help. Best regards, support team.

Fast order processing & shipment

I needed to have the booster delivered for my friend's birthday, as it was supposed to be a birthday present. Fortunately, the sales team quickly processed my order and shipped it in the shortest time possible. I'm very grateful to them!

Hello Edward, thank you for leaving the feedback. We hope your friend liked the present. Best wishes, sales team.

So happy I bought it.

I live in a valley, and had two bars of cell service at best. The installation takes some time. Now it works fantastically. All the components look of good quality. I now have full bars in the house.

Dear Karl, we are glad to know you are enjoying the amplifier! Kind regards, Support team.

This really worked

I live in a very rural area far enough from the cell tower. I could hear callers but they couldn't hear me. This signal booster eliminated my problem. Except for getting the antenna on the roof, the installation process was easy and the cables were long enough to meet my needs. Overall, I’m quite satisfied.

Hi Jo, thank you for your feedback, it means a lot to us! Best regards, Support team

Case Studies

Putting together a cell phone signal repeater is easy and even fun. I had absolutely no problems during the process, even though my technical knowledge is slightly above zero and I could easily mistake one plugging port for another. But I didn’t, thanks to the detailed instructions. The process has just a few simple steps, and the most difficult question I faced was “where to place the booster”.

Andrew Meyer, Cannock

Mobile-signal-boosters website was really helpful, and, I guess, I wouldn’t be able to write and post this review without the help of their technical support. They helped me to choose my perfect and affordable booster model according to my situation and answered all of my questions, even though at first I was sure I chatted with a bot. And eventually I ended up with my Lycamobile signal problem being solved, just as it was promised!

Angel Da Costa, Leicester

It’s a commonly known fact that people usually have weak phone signal in the forests, but I never drew my attention to things like these, until I bought a piece of land with a small cabin on it. Later I found out that there was barely any BT Mobile signal there. The reasons behind it were actually painfully simple: BT Mobile cell phone tower was pretty far away and there was a lot of trees blocking the signal.
