All of the phones now have better coverage

I had decent outdoor coverage with poor indoor speeds

We tried pointing it at towers 2 miles away in EST, and at the towers across Lake Michigan in CST....and while it boosted the coverage from 2-3 bars to 5 or even full

DISCLAIMER: AMAZONE VINE PRODUCTI live in a mountainous suburban area, where Sprint doesn't provide sufficient coverage causing poor data signal & frequent drop calls.
