How it works

Cell Phone Extender Nikrans LCD250-GSM+4G is a device that is designed to simplify your life. It not only perfectly fulfills its function (thanks to its two antennas and a repeater box itself it is able to amplify even the weakest signal and to transmit it to more than one mobile device at the same time), LCD250-GSM+4G makes its usages for you as simply as possible.

To install it, you may need just 30 or 40 minutes and then you can practically forget about it, as it is able to control the external circumstances and adjust necessary settings automatically. When there is no any necessity to improve poor signal as there are no any mobile devices that need to receive it, LCD250-GSM+4G enters an energy saving mode. Moreover, when the necessity appears, an active regime will be switched on also automatically.

The series of GSM + 4G boosters is quite vast and suits for different coverage areas. The most popular option for European and especiaally Spanish networks is LCD-400 GSM+4G mobile signal phone booster.

Too expensive

My friend gave me this booster a month ago, and I’d like to share my impressions. I still don’t understand why it is so expensive. It takes a long time to catch the maximal signal, and the installation is rather complicated. When you’re too far from the indoor antenna you can’t receive the proper signal. Although the design and the quality aren’t bad in general, I still wouldn’t give so much money for it.

Appreciated Tadeusz, thank you for sharing your opinion. Wishing you all the best, sales team.

Amazing for freelancers

If you’re a freelancer and you prefer working comfortably from your home, this booster would be amazing, just as it is for me. It covers my entire house and I never get bad signal. The only thing: you need to find the right place for outdoor antenna which isn't evident.

Hello Gareth, we’re very glad that you love our store. It’s great that we helped you have a good signal. Best regards, Support team.

More Than I Expected

When I was buying this device I didn’t expect to get much result, but fortunately, I was mistaken. In the end I was pleasantly surprised, because the result was even better than I expected. The voice connection became much better. I always have full bars, regardless of my location inside the house. The booster also provided smooth work of high-speed 4G network. I will recommend it to my neighbours, undoubtedly.

Dear Martin, We are happy to know that you are pleased with the result. We would be glad to see you next time. Best regards, support team.

Nice service

I'm pleased with the way the manager has provided me with the consultation. I've received answers to all my questions. The booster fully corresponds to the description and works well.

Dear Roy, thank you for the review. We would be glad to see you at our store again. Kindest regards, the team of Mobile signal boosters.

Amazing device

The reason I wanted to buy a signal enhancer was because my basement had really poor signal, and I wanted to organize a place to relax there as well. With this repeater, I can play videogames and stream movies there!

Hello Pixie, we’re happy to know that our signal repeater helped you so well with receiving signal at your house. Best wishes, Support team.

Didn’t expect it to work so well

Our house is surrounded by large pines, since we basically live in the forest. As you can imagine, the signal won’t be so good in an area like this. And since I didn’t want to cut down any trees, I thought there could be a better idea. When I began looking for options to boost our signal I was really confused, because I found this to be a more complicated pursuit than I had expected. I was getting lost in all of this technical knowledge, bandwidth and other things related to that. Thankfully, the store manager stepped in and helped me a lot with choosing this particular model that I am now absolutely happy with. I had to mount it fairly high (not on any of the pines), since it can’t do magic and works as long as the outside signal exists, but it amplifies it really well and is worth the money without any doubt.

Hi Olly! It’s good to know that you’re so happy with your purchase and the service our manager offered you. Best regards, Support team.

Reliable company

You won’t believe me, but all my neighbours have bought boosters here. This company is reliable and trustworthy, as well as the products they offer.

Hello Jane, we are grateful for your words of appreciation. Hope to see you again. Best regards, support team.

Cool stuff

It works! I bought it at my own risk and decided to install it at home. The installation is simple, especially with the user guide. Before the booster, I had only one bar on the phone, and now it catches 3-4 bars, and the mobile internet works well. Now I can use skype and call my relatives and friends.

Hi Roy, thank you for the review. We are glad to know that you are satisfied with the booster. Kindest regards, sales team.

Everything works fine

I used to miss important calls at the office and it really irritated me. Needless to say, the quality of mobile internet was just awful. Not a singles mobile app worked properly. All my hopes were for this amplifier and, fortunately, it didn’t let me down. The quality of mobile connection at the office is fine now. It should be mentioned that the closer you are to the amplifier, the better the signal is. But it doesn’t mean that in other places there is no connection - using the phone is possible everywhere. I can receive incoming calls everywhere at the office.

Hi David, thank you for the feedback. We are happy to know that you are satisfied with the product. With best wishes, sales team.

The effect is worth the money

I bought the booster for my parents, as their cottage is located deep in the woods, and the mobile coverage there is very poor. The amplifier intensified the signal well. We are pleased with the result and I think that it’s worth the money it costs.

Dear Pierre, thank you for leaving the feedback. Keep on enjoying the result! Wishing you all the best, support team.

Useful thing

I’d spent a lot of time trying to make out how to improve mobile coverage at home. I didn’t want to change my number, changing the operator wasn’t a good option as well. When I learnt that my neighbours were using a mobile signal booster and I immediately bought one for myself. The result is satisfactory. I think this booster is a useful thing for houses where the reception is weak.

Hello Sebastian, we are glad to receive your feedback. Keep on enjoying stable coverage. With best wishes, the team of Mobile-signal-boosters.

Good present for parents

My parents live in the country and they used to tell me about poor mobile connection at their countryside house. That's why I decided to give them this booster as a present. They are so happy about it. The reception is stable now. No worries about poor coverage and insufficient signal level.

Dear Edward, thank you for leaving the feedback. We are glad to hear that your parents liked the product. Wishing you all the best, the team of Mobile signal boosters.

Good product

We had a very poor signal at our apartment. It was almost impossible to speak on the phone and to surf the net. Then we bought this booster and the mobile coverage was improved a lot. I think that this booster is one of the most effective solutions to signal problems, with decent quality and functionality.

Appreciated Dominique, we are grateful for your feedback. Your opinion means much to us. With best wishes, support team.

Good for a small office

We bought this booster for our office located on the basement floor. The effect of the amplifier is absolutely amazing. Both the GSM signal and 4G are amplified. Now working at the office is so convenient!

Dear Oscar, thank you for leaving the review. Keep on enjoying the stable connection at the office. Wishing you all the best, sales department.

Recommend it to anyone with signal issues

I’m currently living outside the city for family reasons, and the closest cell tower turns out to be about 4 kilometers away from my place. This repeater has finally brought decent signal into my home! My phone now catches all of the signal bars (or four out of five), and the internet data speed is much higher than it used to be. I’ll recommend this booster to anyone who’s struggling with poor signal, especially to my friends in the neighborhood. Maybe they’ll need a different model for different needs, but the brand and the store stay the same. I’m really happy with the reception inside my house now.

Hello Vicky, we’re glad that our booster helped you so much. Thank you for your positive review, we’re always happy to help! Best regards, Support team.

Tricky to install

The house I live is incredibly rural. I had only 1 signal bar. If the device is properly and carefully installed, this does the trick. Now I have 4 signal bars inside. The problem is that the exterior antenna is highly sensitive to positioning. Any movements can influence on signal bars.

Dear Bob, thank you for contacting us, we greatly appreciate it. Best regards, Support team.

I would buy here again

The service was perfect as well as the product. Antennas are of high-quality, the cables are long enough, and the booster box is solid and reliable.

Bought it for my family house

My family house is quite big, and we often struggled to get good signal without disruption all over the place. We argued a lot about that, but eventually decided to get a booster. Absolutely not disappointed.

Hi Maximilian, it’s good to know that your family found its peace and good signal with the help of our signal booster! Best regards, Support team.

The problem of communication failures and slow Internet has finally been solved. The amplifier is quite simple to use, it is very easy to install and no additional settings are required. Made of durable material, it has proven its reliability in two months of operation.

Was able to solve my problems

I was looking for a booster to improve calls and ensure fast data for internet connectivity. And finally I've found it! This small device can really do miracles. It solved all my signal issues. Both GSM and 4G are working smoothly with no interference.

Useful that sold by frequency

At first I thought that I could hardly choose the right model, but everything was easier than I expected. All the models are sold according to the frequencies they improve and to the indoor coverage capacity. So I just checked the working frequencies of my operator, contacted the support team and they offered me a few options. In a few minutes, my order was already processed. The booster arrived in three days, and it works without any complaints.

Appreciated Ben, we are glad to receive your feedback. Thank you for choosing our product. Best regards, support team.

Good product

I’ve already been using this booster for a year. The overall impression is good. The device is easily installed, it really enhances and stabilizes mobile communication. Although I have to admit that it didn’t affect the quality of the mobile Internet as I wanted. 4G was improved only by 50-60% percent, while I expected much more.

Hello Gustavo, thank you for leaving the review. Your opinion is very important for us. With best regards, sales department.

Be aware of self-excitation

At startup, I faced the problem of self-excitation despite the fact that the outdoor antenna was already on the roof. As it turned out, the problem was in a small section of the cable, where it went next to the cable from the TV antenna, as a result, part of the emitted signal to the external antenna of the repeater, via the TV cable, returned to the room where the indoor unit stood. Plus, an unnecessary turn of the outer cable near the antenna could affect, which added inconsistencies and reflections. Fortunately, when I fixed all the bugs, everything became all right.

Hello Kira, thank you for the feedback. Don’t hesitate to contact us in case you need help. With best wishes, support team.

I’m impressed!

Hello everyone! I’ve never left any reviews, but this time I’ve decided to write one just because I cannot but tell you about this wonderful device. I work in an office space where my mobile phone doesn’t catch any signal at all (it shows one bar, but calls don’t go through). So in order to talk I had too go outside. However mobile Internet didn’t work outside the office either. One day I understood that I need to do something to solve this unpleasant situation. I bought this booster and it helped me get rid of all the problems I had. My phone catches 4-5 bars stably at the office. I’m really impressed! Such a compact device with such a great power and efficiency!

Dear Richard, thank you for the review. We are happy to know that your problems have been solved. Regards, sales team.

Got what I wanted

Strengthens the signal even in my village with very weak network signal. I had to go outside in order to make a call and now the quality of voice connection is stable in the house. As for 4G, it has appeared even in the rooms where we had no mobile internet at all. The quality of the product itself is very good. It looks reliable!

Appreciated Ronald, thank you for the review. we are glad to know that you are satisfied with the result. Kindest regards, support team.

Unnoticeable but effective

Very nice booster, so compact and lightweight! The level of signal is increased twice, no more signal issues, the audibility during the conversation is good and the internet connection is stable.

Improves Signal Well

This is my second booster for home. The first model was also purchased here, but it improved only GSM signal, and I’ve decided to change it for a more advanced model. As my house isn’t very large, this model is enough with its coverage of 250 m2. The amplifier improves signal well. There are no problems with it.

Dear Allen, thank you for the review. Hope to see you at our store again. Best regards, support team.

Didn’t need to change the operator

My signal troubles were so annoying that I was thinking of breaking up the contract with my operator. Turns out it wasn’t their fault, and a signal amplifier helped me out with everything. The solution was much easier than I thought though the delivery was a bit long.

Hi Bonnie, it’s good to hear that your problems are solved so easily! Sincerely, Support team.

Bought one for myself and recommended at work

After I bought this amplifier, I was very curious to test it. My iPhone’s Field Test mode showed a significantly stronger signal right next to the booster and its inner antenna. Throughout the house the signal has changed a little, but it didn’t become less than three bars. I also switched the booster off and back on a couple of times. It wasn’t necessary, but I was curious, and the Field Test mode showed that the signal goes up just a few seconds after the booster is switched on. I was really satisfied with how It works, so I recommended it to my boss, and he ordered one for our office as well.

Hello Nel! Thank you for your review. We’re very glad that you and your boss like this model so much! Best regards, Support team.

Forgot about my signal issues

I’ve had a cell phone signal issue for a long time, and now I realize how absurd it was of me not to try and solve it before, knowing now how easy it is. I simply purchased a booster, it arrived to my place quickly, and I think it took me more time to unwrap the details than to actually mount them. Easy and fast, and the instructions were clear. No more signal issues for me, thanks to NS-2500GD and the company!

Hi Ewen! It’s good to know that you’re so happy with your purchase. Please enjoy your stable internet connection and phone calls! Best regards, Support team.

Works great

The parcel arrived really quickly and everything works! I purchased it for my parents’ summer cottage, and it works all over the plot that they own, because the working range is big. We ran several speed tests and found no issues whatsoever. My parents are very happy with this signal repeater, they can now use internet and receive phone calls in their cottage without going outside, which can be hard for elderly people.

Hi Abbey! We’re happy that our repeater made your parents’ lives more comfortable. Please contact us if you, or they, have any more questions. Best regards, Support team.

Case Studies

Fast delivery is everything! My situation was an emergency, since no one at my company could work efficiently while having terrible Vodafone signal problems, and the cell phone booster I ordered arrived in just a couple of days, exactly as it was promised. No mistakes during the delivery or with the order, every single detail is very carefully packed and there’s no need to buy any additional wires or power plugs.

Paul Dass, Swindon

I tested out the signal for several days after I turned on the booster. It was stable anywhere inside the working range of the booster, my internet speed was very good no matter what I was doing and where I was, and I could do anything that I needed – from interviews via videochat to watching movies online. The signal never interrupts or slows down my working process anymore, and it honestly feels very good.

Philippe Doherty, Huddersfield

Due to some circumstances in my life, I had to move out of a big house and live in another part of the town. It all caused me no problems except for one thing. There were no Lycamobile signal problems at my old place, but the new apartment had severe signal issues. I was basically erased from my friends’ and family radars, because they couldn’t reach me. It was frustrating, and something really needed to be done.
