I'm on Freedom Mobile and it sucks major buffalo balls at my house. I'm using a Samsung J7 with Band 4 and Band 66 but my signal still sucks. I then switch to an iPhone 6 with Band 13 and there's no improvement to the signal strength. Is there an app on Android that can force the phone to pick which frequency band the phone uses. I got Signal Spy installed right now and it's showing I'm on Band 3, which doesn't even make sense since Freedom don't use Band 3.
