Works great at 4G, but not T-Mobile 5G

Although it says it supports 5G, it doesn't support T-Mobile 5G. I had to revert back to my old 4G phone in order to use it. That's OK because my reception was so bad that the 4G is much faster than 5G. There customer support was outstanding in helping me get everything setup.

I just connected it via Bluetooth, and it all worked!

I moved into a new house and struggled for a whole year. Nobody could reach me, and I had to go outside just to talk on the phone. I even switched mobile carriers, but it didn’t help! After a year, I started looking for a solution and bought this signal booster. And what a miracle! Now, instead of SOS, I have 3-4 bars of signal on my phone. I couldn't figure out the recommended apps; for some reason, they didn't work, but I connected my phone without an app and saw that the cellular signal improved significantly! Thank you!

Gets me great signal

So I live in a very rural area, little to no signal at all. After I installed the booster my guest and I have full bars LTE all the time. In fact I actually game on my computer with my hotspot and stream entertainment without inconvenience due to the booster. I would definitely suggest this to everyone.

Happy customer.

I live out in the country with almost no cell signal. I now have 3 and 4 bars. This product worked. Install was fairly easy and I'm very happy with the results.
