Good result

The results of using this booster for a weak are good. I can move around the house without being afraid to lose the signal. 4G connection is speedy and without any interruptions, voice communication is good as well though upstairs only 3 bars.

Dear Leo, thank you for the feedback and we are glad that the booster improved your communication. Best regards, Support team.

It Works!

I used to have almost no signal at the office and with this device I have a stable network without turns off. I am totally pleased with the result. The only inconvenience of the booster for me is however the necessity to fix the antenna outdoors which is not always easy to do especially if you rent an office.

Dear Oscar, thank you for the review. We are glad that you are satisfied with the results. Best regards, support team.

It’s worth its money

Wide range of boosters

I bought two boosters here - LCD400-GSM+4G for house and another one with larger indoor coverage for my office (NS-2500GDW). I liked one more – a car booster. I think that I will buy that one as well.

Dear Mia, thank you very much for the review. We would be glad to help you choose a car booster. Best regards, Support team.

Frank Linscott, Yeovil

All components in one package.

All the details that we found inside the package after its arrival, were very well-packed, of nice quality and all in their places where they should have been. The parcel has arrived very soon indeed, unlike it usually happens in lots of other online stores even if they promise the fastest delivery ever. Everything, including the cables, was already there, which was very time- and money-saving.

Abbie Houle, Stockport

Thу deviced saved our situation with Internet connection.

At Mobile-phone-signal-boosters.co.uk website we were recommended to buy the model that was ideal for the size of our office (we rent only one floor, but it’s quite a wide space), and was suitable for Freedom Pop frequencies and 4G internet. We didn’t have too much spare money, and the price of the booster seemed good. We were also fascinated by the promise that the signal repeater would be delivered in just several working days.
