No more missed calls in the office thanks to our new GSM 3G 4G LTE indoor antenna booster.

No more missed calls in the office thanks to our new GSM 3G 4G LTE indoor antenna booster.

Zac Rendle (Australia, Maryborough)


I usually had one bar in the office and frequently interrupted calls. I have changed providers several times, but without tangible result.

I bought this unit based on the reviews. When I heard about NS-2000EDWL GSM 3G 4G LTE indoor antenna booster I was skeptical enough because I thought I would never have a smartphone that worked in the office. But finally I was willing to try a signal repeater. Now, I have a good enough signal to talk throughout the office.

There are people that had bad experiences with this device, and I am absolutely sure that was because of improper installation.Installation was simple. Once the amplifier was installed, now I get a solid 3-4 bars in my office. The GSM 3G 4G LTE indoor antenna booster does as it's advertised but make sure that you mount the antenna in a place where you receive a strong signal. If you are getting only one bar where you place the antenna don't expect this device to boost that signal as it only repeats the signal it's receiving from the outside.

I am very pleased with the amplifier and would recommend it. It perfectly improves the quality of GSM, 3G and 4G connection. I'm certain there are devices that would provide better signal, but absolutely not at this price. And I didn;t have to buy separate devices: one of GSM signal boosters, cell phone booster 3G and 4G amplifier. Overall the signal repeater works as expected, robustly and reliably.

Our office is free from Claro signal problems now thanks to Nikrans best signal cell phone booster.

It’s a tiny compact thing and it doesn’t require much space or energy. We don’t have to link every single computer to it using wires, since it sends out the signal wirelessly, and this is amazing, because can you imagine what kind of nightmare would this be? And now we are all happy with this purchase and thank MyAmplifiers store a lot for restoring out working efficiency.

No more missed calls in the office thanks to our new GSM 3G 4G LTE indoor antenna booster.

I have a basement office in an Australian town where mobile signals are weak. The building is about 4-6 miles from the nearest cell tower. Lost and missed calls inside the office were common and caused a big annoyance. Actually, my mobile phone was worthless inside. It used to be that I had to go outside the building to talk on my phone, and place it next to a window to get it to pick up enough of a signal to even ring.

Finally uninterrupted calls and fast Internet without Tele2 signal problems.

My boss rewarded me because I gave him a good advice that really helped everyone, and he says that this purchase didn’t even effect the budget in a bad way, because no matter how huge the working area of the amplifier is, the price is still really low and attractive. It was a perfect solution to Tele2 poor signal, and we are very satisfied with our purchase from MyAmplifiers store.
