Using with T-Mobile WiFi and it went from barely able to stream Netflix on one device to streaming on two and three phones and a Xbox all going, obviously not everyone will get that lucky but I will say it made a huge difference in our single wide trailer- EDIT-been a about 3 months and the antenna connections on T-Mobile both 1&2 seemed to stop working and switched to 3&4 and I had to reposition the antenna but just use googles free speed test on your phone and walk around till you find a solid signal and mount it in that area. Still currently happy with it months later and willUpdate if anything changes

We have T Mobil, Wife works from home and Needed faster upload speed. I installed antenna as per instructions and our upload and download speed dropped lower than using T Mobil gateway internal antenna. So I did some research and found the company Waveform, 8x more cost, but no other choice other than going back to Xfinity. We bit the bullet and then ordered the Waveform Quad 4x4 Mimo and WOW all speeds exceeded the minimum speed required to preform her job. So I decided to make a bird feeder out of this antenna instead of throwing it away.

Worked well with t-mobile home internet router

Didn't make a difference, in fact, my connection was worse when using it

I mounted this on my boat and connect it to my hot spot and gave me data signal where I barely had any.
