The NS-500GD dualband cell phone repeater is designed to amplify two different GSM frequencies at the same time. It boosts signals at 900 and 1800 MHz frequencies, which are the most commonly used frequencies by the operators worldwide and for sure in the UK. With an impressive coverage area of up to 5000 ft2 (500 m2) forget about dropped calls at your villas, offices, big apartments or even underground offices/cafes.

The best feature about this model is that it amplifies both 3G and 4G networks simultaneously, provided that your network provider operates at 3G 900 MHz and 4G 1800 MHz frequencies, respectively.

All Nikrans boosters come with CE and RoHS certificates proving that these devices have passed all safety and quality tests. As such, they do not emit harmful radiations.

So, if you are suffering from poor connectivity issues, dropped calls and slow 3G/4G internet, now is the time to live a hassle-free life. Get your Nikrans NS-500GD dualband mobile phone repeater now.

Some european providers also use 900 MHz frequency for 3G Internet connection. So if your mobile operator supports 3G 900 MHz, this booster will improve both your phone calls and 3G Internet connection.

How it works

Having a coverage area of up to 500 m2 (5400 ft2), Nikrans NS-500GD dualband mobile phone repeater is a suitable option for those who need to improve their mobile connection in their private houses or office facilities. This signal repeater has such important features as automatic control of gain and signal level. It means that you can just switch your booster on and enjoy its work without any necessity to worry about its functioning. Nevertheless, if you want to change its gain due to your individual requirements, there is an opportunity to do it manually. Moreover, thanks to a shut-off function, your NS-500GD is protected from installation and network errors.

My family liked it

I bought this device to amplify poor mobile reception at home. My wife and I are using it for better GSM and my children for improving the internet. So far we have noticed no disadvantages. Everything is all right. The repeater is nice. The shipping was fast. The installation wasn’t difficult and it works without errors. Before the purchase the phone caught signal only in one room, now we enjoy great coverage around the whole area.

Dear David, thank you for the review. We are glad to know that your family is satisfied with the booster. Best regards, Support team.

There used to be signal in my house only near the window. Now with the repeater I have full bars. My brother installed the device easily, as he has the same at his house. We placed the outdoor antenna on the roof in the direction of the provider’s mast and the indoor antenna was placed in the hall. The signal is stable around the whole area, without interruptions. Youtube works without any problems. Voice connection is good as well.

Dear Donna, thank you very much for the review. We are glad that you are happy with the result. Best regards, Support team

Significantly improves weak signal

I use it in my café where the reception isn’t good. My husband installed the outdoor antenna outside the window. The indoor antenna with the booster box itself was installed in the central part of the café. Everything is okay, the device improves poor signal without problems.

Dear Deborah, thank you for the review. We are happy to know that you are pleased with the purchase. Best regards, Support team.

Reliable supplier

It’s not the first time I have turned to this supplier for an amplification systems. I have already bought one for my house and one for my office. And this third model was purchased for my friends, as a present. Hope they will like it!

Dear Ron, thank you for the feedback. We would be glad to see you at our store next time. Best regards, Support team.

Nice device

This model isn’t very cheap I must say but it works well. I have bought already four of them, for my neighbours in the village. Everyone is satisfied.

Dear Andrew, thank you for the feedback. We are glad to be useful to you and your neighbours. Best regards, Support team.

Great characteristics

I am fully satisfied with the product. It corresponds to the description provided by the supplier. Amplifies both voice communication and the internet, and does it effectively, without any errors. It’s convenient that the model has automatic and manual gain control so I can choose the one I need. All the accessories needed for the installation and mounting were supplied together with the booster.

Dear Freddy, thank you for the feedback. We are glad to know that you are happy with your purchase. Kindest regards, Support team.

Reasonable price

I like this model as the price is reasonable and the characteristics are suitable for my office. The booster stabilizes voice connection and helps to make the mobile internet much faster. I only advice you to check the frequency your operator uses in order not to make a mistake when choosing a device. The previous booster I used didn’t amplify 3G as it wasn’t compatible with my network. This one is all right as it works with all providers in the area. As for the price – it is the lowest I have seen so far for such kind of a device. What is more, the company often offers discounts and coupons.

Dear Charles, thank you for the review. We are happy to know that your problem has been solved. Best regards, Support team.

I’ve installed it at home. Works without interference. GSM is stable now as well as 3G. In the places where there used to be no reception at all I always have 3-4 bars now. The indoor coverage is enough for my area – the house is about 280 m2.

Dear Paul, thank you for the feedback. We would be glad to see you at our store again. Best regards, Support team.

Works Great!

The order came in three days. Everything corresponds to the description provided. All accessories necessary for the mounting were included in the installation kit. I’ve already set it up. Works great! Recommend!

Good Product

I recommend it! I bought this device for my granny, who lives in the village. Mobile connection there is very poor. Before the installation we had no connection at all. It was unbearable! It sounds ridiculous, but I had to stand on a chair to catch a signal and make a call. With this booster everything has changed, the signal has become much stronger. The quality of GSM connection as well as 3G is more or less stable. My husband had to spend a little time in order to find the best position for the outdoor antenna, but there was nothing impossible for us! The user’s manual was really helpful as all necessary information was provided there.

Dear Sarah, thank you for the review. In case you have any questions, feel free to contact us. Best regards, Support team.

Case Studies

Jane Nugent, Galway

Three signal problems are forgotten! technical service is just wonderful. I had a lot of questions, because I have never heard about signal amplifiers before, and they answered all of them and provided me with the information so clear, that even I managed to understand how it all works. They assured me that my signal problems are very easy to deal with, and it all can be done at a nice price. So huge thanks to them for giving me all this info!

Roy Aspinall, Scunthorpe

Finally I stay connected to the world!

After I made an order at, my parcel came in just two days, which is a truly amazing delivery speed. Then I took the box with the booster to my remote cabin. Fortunately, I didn’t need any internet for the assembling process, because the user instructions were printed on paper and put inside the box together with other details. It is really handy for people who have signal problems.

Bill Mosier, London

This solution worked out for us!

My wife and I desperately wanted to keep our current Vodafone tariff despite Vodafone signal issues, because the price was good and we needed two routers at once: for our apartment and for the office. To remain Vodafone subscribers and also have 3G and GSM signals in both places, we needed something that would improve the signal – a signal repeater. We decided to try buying one and see if it would really help us.
