(As mentioned, my phone doesn't support my carriers LTE band, apparently they'll only use one around here or something.

Band 12 is slow in my area, giving me 3mbit/s or less while Band 4 gives me 20mbit/s most of the time but without the booster, speeds would vary depending on where I was in the house

No more dropped calls when using nearby device.- Works with multiple carriers.- works as
