How it works

1800 MHz Mobile Phone Repeater Nikrans LCD-400D has a high-tech and very pleasant design, moreover, it is very compact which means that it can be installed practically in every room even without being noticed. It has an extended coverage area. It gives you an opportunity to use this booster for houses, office buildings, shops and hotels with several floors. If the structure of the building where you need to improve mobile signal is too complex, you can use special splitters and additional indoor antennas (a standard set includes one antenna that should be used inside and one antenna that should be installed outdoors to catch at least poor signal of your carrier) which will guarantee better coverage in the rooms that are rather remote from the place where LCD-400D booster box is located.

Effective for EE

I recommend the product and the seller. The device works without any troubles, the managers are real professionals. Check your operator's bands as the booster doesn't support all of them.

Dear Ella, thank you for the review. This model supports only one frequency band so in order that it works properly it's necessary to know the operator's frequency. Best regards, Support team.

Nice repeater

The order was delivered very fast, for which thank you very much! The amplifier works great. The coverage area isn’t very large, but for a medium-sized apartment it’s enough. For a large country house or villa you may need another model.

Dear Leo, thank you for the feedback. Your opinion means much to us. Best regards, Support team.

Not bad

I bought it last year to replace the older booster model, which I had used before. In general, it’s not bad. Works rather well, though improves only up to 3 bars inside the building which is about 300 square meters. All the fixation elements and cables of the recommended length were included in the full set, so I didn’t buy anything extra.

Dear Ruby, thank you for leaving a review. We will be happy to see you again. Best regards, Support team.

Positive impression

Using the device leaves only positive impressions. First of all, I liked the result of its work – stable mobile connection, speedy 4G internet, and not a single dropped call. Secondly, the booster is compact and light, the size is 165x115x35 and the weight is about half a kilo. And finally, the price was very attractive and tempting. I will recommend this booster to all my friends who have the same problem as me!

Hi, Jacob! Thank you very much for the review. Your opinion is very important for us. Kindest regards, Support team.

No more network problems

If you constantly suffer from signal problems and poor reception, this thing is what you need. My operator is EE so the device effectively boost signal and ensures stable internet connection. I have been using it since last year and I have had no signal issues since then. If previously I got nervous whenever I made or received a call - now I get 100% satisfaction from using my smartphone. The audibility is very good, there are no more disconnections during conversations.

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

Case Studies

Thomas Marbach, Kirriemuir

Perfect choice for my O2 signal problems!

The assembling process of my LCD booster is the easiest device-related assembling process you could ever face. I easily did at by myself in a few very easy steps and it’s impossible to do anything wrong! I am very satisfied with the result and the fact that they put clear and detailed instructions into every package so that everyone can understand how to put the signal booster together.
John Brink, Chichester

Extremely happy with my signal booster!

Despite the fact that I have reasons to like my operator, I was stuck in the house with poor and interrupting signal, while I needed internet badly because I was looking for a job and doing freelance assignments at the time. Signal issues made my working process a lot harder and annoyed me really much, so I decided to change that and do something about the signal. My family said I should try to buy a signal booster.

Sheldon Birchall, Doncaster

The booster arrived quicly after I passed the order.

I didn’t have to wait too long for my order to arrive. Just as it was promised on’ website, it was delivered to me very quickly – in three days. I wasn’t expecting it this early (and I totally forgot about the tracking number while being busy with other things), so it was a really pleasant surprise. All the parts that were needed to amplify my poor signal were already in the package.
