KKBSTR Cell Phone Signal Booster, Verizon 4G Amplifier, B2 B4 B13 Tri-Band Repeater for Home and Office

I can’t believe this device can make it my phone signal this so strong, before using this device, I was always have problems with phone call quality, now no more this issue, I can clearly hearing with every phone call.

I'm a novice when it comes to cell phone technology but I bought an international phone that won't allow me to use wifi calling and our home internet is unrelianle at best. With no signal booster I have to stand in one corner of the house to make a phone call and there is absolutely no internet connection on my phone. Now with this signal booster I have full bars and I'm able to watch Netflix on the stadard def with my phone.I'm on at&t gsm network so I can't speak for other carriers technology but this works great if you have at&t or similar providers.

First review: We barely get cell phone coverage and only in the room with the antennae.Second review: After seeing my review that I wasn't getting coverage, the company OFFERED to refund my money. The booster works well for some, so don't let my review cloud your judgment. Five-star rating for superior customer service!!!

Using in a metal topped camp of about 1100' . Before I only had one bar if standing outside on the porch. No svs inside. Now have 3-4 bars if close to the inside antenna and 2 no matter where I am. Pleased with the product and the price. BUT..... the instructions suck. Tiny and unclear. And the items in the box should be clearly marked but are not.

It works far better than our old booster so far only had it a month. Very easy t.o install

We had NO reception at our cabin in the woods. Even walking around outside holding the phone in all directions. We had to drive 1/4 mile to get a signal of 3 bars. Verizon was OK, just. But AT&T or TMOBILE forget it.Bought this cheap version. Plugged it in with the aerial up on the roof, the booster box downstairs.WOW!! 4 bars and 3G. No lie. We have for the first time communication with the world. Stream TV. Netflix and Amazon.Answer calls. Make calls and hot spot to other iPads and phones etc. The phone must be alongside the mini Ariel to work. But Hey. Who cares? I have contact with the outside world.Verizon. NOLTE. NO3G 4 Star. YES.

Helped boost the signal inside the structure

This product works if it’s a sunny day with no clouds in the sky. I went from have 0 bars to at least have extended and even 3G sometimes. Still can’t make or take any phone calls though. This also wasn’t very helpful since I live in an apartment complex and I couldn’t actually mount the atena to the roof (I used a tree). This product also didn’t come with an instruction manual so I had to do some research online.
