The Cellet Car Cellular Phone Signal Booster & Repeater Antenna is a passive device designed exclusively for vehicles, enhancing 5G and 4G LTE signals by redirecting existing tower signals. It requires a minimum existing signal and optimal installation—placing the external antenna on the car window and the internal repeater 3 feet below it—to improve connectivity across major US carriers like Verizon, AT&T, Sprint, and T-Mobile. Lightweight and easy to install, it’s perfect for professionals who demand reliable mobile coverage on the move.

great to penetrate walls
really good, you can use any app to see it increases signal strength. Works to penetrate things like walls or the car. will not magically give you internet.
P**!
Totally Garbage
Doesn't work at ALL!!! Total garbage! That's exactly where I had to put it, in the garbage. Don't waste your money! I only gave it one star so I could do a review.

no response from seller
This worked well however after a car accident I decided to remove the device. I mounted the outdoor Antenna onto my windshield, and during inspection after remove a clear outline of where the product was was left behind. I reached out to the supplier months after purchase and mentioned the car accident, as to maybe get some help on a replacement. They gave me zero responses and ended the conversation then.

Signals or no signals, that was the question now we know the answer
OK, so I got to test this thing out today which is the 28th and even though it’s cheap don’t waste your money. This thing is a piece of trash and I’m gonna change. They’re just freaking pulling in your chain so don’t order it. It was just a hillside see I got my antenna and look right across the way on top of the hill. There is a cell tower and guess what this thing doesn’t catch🤔 signals.

waste of money
A waist of money dose absolutely nothing no change in signal or bandwidth! I took a test before installing the booster and after…no difference! Don’t waste your money or time!

Works
This isnt gonna take you from no service to full service. But it took me from no service to having a usable phone. It adds about a bar or 2 of signal. Worth it. Will be putting on more of my stuff.

For a cargo trailer camper- it helps!
I built a cargo camper and installed a single small window - absolutely no signal on my cell phone, no bars. I attached this on the window and now I can get a single bar when I’m close to the window and can make phone calls.

No help with signal
No boost of signal here . I live in the middle of nowhere and it sure did not help. Maybe in other areas but not here . I would say just save your money I bought it so you did not have to.
