Thanks for the partial answer, but that just leaves me with more questions. Why doesn't the iPhone 5 while the tab 3 does?
And I have a spark device, the tab 4. That one won't connect but every other android device will. I live in uptown beckley so it's not an issue of me not having it when I'm at home. I get 3 bars on average. And the speed doesn't bother me, it's the latency since I use voip instead of normal cell phone service.
The issue with the dropping is when I get closer to my job, but I'm still outdoors and on foot since I don't drive. I didn't look at the device constantly because I'm looking out for cars that want to hit me if I'm not careful. Save a lot is where I think it drops to 3G, which isn't so bad until network congestion happens and the latency and speed drops to near unuasable levels.
Basically here is the list of devices that will connect to the lte:
Tab3
3xHydro icons (band 25 from the signal check pro app)
Devices that won't connect:
3x iPhone 5 (long story)
Tab4 (it's spark like you said. So why?)
