Agree everyone's experience will differ. All I can tell you is that after MANY years in the exact same spots I've tested in the Milw area Sprint sucks to say the least. Just did a test from my house in Waukesha. Outside in a Spark listed strong signal area. Sprint iPhone 6; 2.0 megabit D/L, .5 megabits U/P. Att iPhone 6 in same spot. 18 megabit down, 9 megabit up. I can repeat this in West Allis where I work with similar results.
