NS-250GDW Overview

Triband mobile repeater Nikrans NS250GDW amplifies mobile signal at three different frequency bands simultaneously - DCS 1800MHz, GSM 900MHz and 3G 2100MHz. This repeater is valid for all mobile networks across the European Union, Asia and Africa.

This mobile broadband booster is designed for middle-sized indoor locations up to 250m2 (2700 ft2), so it will be ideal for private houses, offices, shops and cafes located in underground or rural areas.

Nikrans NS250GDW has some specific features that make its work more effective:

  • Automatic Level Control, ALC, automatically fixes repeater output level depending on the input signal strength.
  • Automatic Gain Control, AGC, intelligently adjusts gain level according to signal fluctuation.
  • Manual Gain Control, MGC, permits users to regulate gain manually basing on individual signal reception conditions.
  • Shut-Off function helps the booster avoid self-oscillation caused by excessive incoming signal strength or improper installation.

The major feature of the Triband model is its multifunctional capability. The tri band repeater ns250gdw improves phone calls on 900 and 1800MHz; boosts 3G Internet on 2100 and 900MHz, and optionally supports LTE connection on 1800MHz. So thanks to NS250GDW you will get reliable phone calls, 3G and 4G connection.

This mobile broadband booster is CE and RoHS certified, consequently it meets the European quality and safety legislations.

Order this Nikrans triband and cellular signals at both GSM and 3G frequencies will be always stable in your area!

The parcel is shipped in a full kit including everything necessary for proper installation and usage. The installation process of the device is simple and it doesn’t require specific knowledge or skills. All you need is to fix two antennas and connect them with a booster with the help of cables. After you switch it on, the coverage in the area will become optimal automatically in 5-7 seconds.

This mobile broadband booster is a safe and healthy product as users don´t get irradiated with it. Inversely, after improvement of the signal a mobile phone emits much less radiation than in coverage shortage conditions.

Our Triband is a perfect way out for those who need to amplify weak GSM and 3G signals at one and the same time!

Our Professional Team is always ready to answer all your questions.

NS-250GDW Customer Stories

Hi-tech booster that spared us of Lebara signal problems!
Hi-tech booster that spared us of Lebara signal problems!

Grace Meakin (United Kingdom, Colnbrook)

Not so long ago I gave my son a gaming console for his birthday, and it turned out that our internet speed was not good enough for it to work properly. We have never noticed that before, because we haven’t really been using the internet very much, and now we figured out that the speed we had was much lower than the provider promised us, and that the connection was failing sometimes.

Brilliant service and mobile phone booster! I'm free of Elisa signal problems!

I simply adored my whole experience with MyAmplifiers! It just feels like they really do make everything to leave you happy and satisfied not only with their product, but also with their service. As the service, certainly, was the first thing that I saw from the company, let’s start from it: Service.

I said 'Good-bye! to signal issue with POST Telecom phone signal booster

I didn’t even need any help with choosing the right signal booster for me – the whole interface of the website is extremely simple, and I loved that. I was a bit concerned about the fact that MyAmplifiers is not a local company. But I was happy to get to know that my payment will be safe and sound thanks to the security system.

Quick delivery despite COVID-19 outbreak

I am really happy that I decided to order a booster on Due to the pandemic of coronavirus, we have taken a decision to stay at home. But of course, in our case self-isolation could have presupposed full isolation from the whole world as the quality of our mobile signal at home used to leave much to desire.

If you want to buy a booster but still have some doubts, I hope that my words will help you to make the right choice:) I do not regret buying this booster, even though initially I also have a rather skeptical opinion.

Reliability and power of the device.

Cool booster:) I have nothing to add:) Probably you need to install it at your place to understand all its benefits.

Thanks! The booster is better than I expected. I mean, I didn’t think that it could be so effective and powerful.

Good price, fast delivery, professional instructions from the support team.

Purchased Nikrans NS-250GDW

Even though my parents didn’t believe that just a strange box with two antennas would help us to improve our mobile connection, I still ordered this booster. And can you imagine how surprised they were when they realized that it’s really helpful? The coverage of the device is not very wide, but for our flat, it’s more than enough. Unfortunately, our dog has spoilt one of the cables, but I’ve already ordered a new one. Hope that it will have a longer life than the previous cable.

Thank you! There is nothing bad that I can say about my interaction with this company. The quality of the device is even higher than we expected to get. It works efficiently, and our connection is finally stabilized.

Purchased Nikrans NS-250GDW

It’s definitely 5 out of 5. The only disadvantage (or the aspect that can be considered as a disadvantage) is the price. Unfortunately, I know that not all families can afford it; for example, my parents couldn’t. But I bought it for them, and they are very happy.

Purchased Nikrans NS-250GDW

This booster is a very good variant for our small office. It’s powerful, it supports multiple connections, it consumes little energy. There is only one problem. Quite soon we are going to rent a new additional room in the same building, and we are preoccupied that the guys who will be working there won’t be able to enjoy our stable signal. But I’ve already contacted the specialists of the company and got a recommendation to buy an additional splitter. I hope it will work.

Purchased Nikrans NS-250GDW

I moved to Ravensburg just a couple of months ago when I decided to start my studies there. The town itself captured my heart just at once. But I needed to solve a couple of issues before I could start enjoying my student life. The first thing was to find a flat (I managed to do it rather quickly). And the second thing was directly connected to the first one: to find a way to improve my mobile connection there. At first, I thought that maybe the mobile operator that I chose was not a very reliable one. But my neighbor told me that subscribers of all carriers who provide their services in the country have the same problem. He also recommended me to buy a booster just like they all had already done. I found MyAmplifiers website and was impressed to see such a wide choice. I didn’t need something extraordinary that’s why I ordered NS-250GDW. I think it’s just something of the middle class. And you know, it’s cool. It improves all the types of signal and works without interruptions.

I bought this signal repeater for my parents. They are 100% satisfied. Now they can enjoy excellent connection without any special efforts. By the way, my dad installed the device on his own and was extremely proud of himself :)

Excellent repeater and excellent company! Thanks! I am happy that I managed to save money to buy NS-250GDW.

Compact sizes, easy installation, seamless work. There are no showrooms in our country. But it would be cool if a customer could touch the device before ordering it.

NS-250GDW is a good device. I installed it five months ago, and since that time I haven’t had any problems with it.

Quality of the device. Its price.

R (Bulgaria)
Verified Buyer
Purchased Nikrans NS-250GDW

Many thanks for this repeater. Usually, I don’t make such serious purchases online, and I don’t read reviews. But a booster is a quite specific device, so I didn’t manage to find a good variant in traditional shops (the majority of the devices that I found were either too expensive or too weak). As I don’t like online shopping, for me, it was quite stressful for me to place an order, but everything was okay. I didn’t have any problems with payments, the order arrived quickly.

E (Belgium)
Verified Buyer
Purchased Nikrans NS-250GDW

I don’t know how it happened, but when I was analyzing different models of extenders to make my perfect choice, I didn’t include this one in my shortlist. Maybe it happened just because I hadn’t noticed it or due to some purely technical issues. But after my first “round of analysis”, I didn’t find something that I wanted. I was ready to give up but decided to contact the sales team in order to ask for their recommendations just to be on a safe side. And after listening to my story, Anna recommended me NS-250GDW. I was surprised to see this booster, but I liked it. Practically immediately, I placed my order, and in 6 days I got it. The amplifier really turned out to be so cool as I expected.

It’s a great thing! Frankly speaking, I have never regretted the purchase. The booster is very helpful, especially at the cottage, where I have no mobile coverage at all. After the installation the signal has become better and more stable. The only minus is a little bit high price, but it’s worth it!

This is a fantastic device! It works on 3 frequencies at the same time and suits for ALL providers of Spain! Perfect coverage, easy installation. Also want to say thanks for friendly support.

The booster is very comfortable to use. I didn’t install any software and didn’t buy any mountings for the set up. All necessary accessories were sent together with the amplifier and the antennas and I managed to install the device on my own guided by the instructions given. Works perfectly, without any complaints.

This device is a very good if not the best solution to mobile signal problems. I’ve chosen an amplifier which improves both voice connection and mobile internet. The characteristics were suitable for me (I mean the working frequencies and the indoor coverage). The result of the amplifier’s work is really impressive. Stable connection and speedy internet!

Super satisfied with the booster. Significantly improves phone calls audibility, 3G Internet quality. The delivery was fast, tracking option. The device is simple yet complete - you have all to set up the system and get perfect conection.

Quite low-priced for good quality. Perfect for those who needs a booster for small area but with all possible frequencies in one device. Indoor antenna could be more powerful.

What a wonderful device! The repeater has a lot of pluses, as for the disadvantages – I haven’t noticed them yet. I installed it in my shop, where the coverage was poor. Now my customers have no problems with reception. They easily make calls, use mobile internet and apps. As the device can be used by numerous people, all visitors can benefit from its work.

Just installed this booster. Lost some time to find the best location for the antennas and to run the cabling inside the house, but once installed the booster did not keep me waiting for the result – 5 bars instead of 2. Plus, 3G Internet without interruption. Highly recommend this!

All features function as advertised. Covers the whole house and a bit of terrace – nice for the summer bbq’s)) Delivery took a week, but that is no big thing providing what I got.
