Okay, I see that you are using a LTE tri band Device. My friend... I have some difficult news for you. The antenna in the phone is built to only receive one signal at a time... Either data or voice. Now the phone when you are using it or it's awake, is constantly switching to check for incoming calls, or texts. Now, when the phone is not actively connected, the tower is supposed to offer a signal called Circuit Switch Fallback. This signal is carried to the device and tells it "Hey. your on Data, wake the hell up and switch to Voice ." Or vice versa. Well, if you don't have that signal, Nd phone is not trying to switch.... You either get backed up calls, or texts without notifications. I still can't get any acknowledge from customer service that this exists. It took lots of time and deduction to find this out. Also, after posting on the Sprint community forums with A explanation for this my Sprint.com account was deleted and I am not allowed to post on the website any longer. Here's my question.... Do I need a lawyer? They told me upon Purchasing my HTC One Max and dropping about 400. Dollars for the service that I would be in the second best network, 4g (dont have Spark here yet) and my phone would take fullest advantage. I now live in Fear of not receiving calls or texts when I haven't gotten any in a few hours. It's paranoia on the verge of insanity. And when I call all I'd like it's maybe the 30 for unlitmited data taken off till my area is upgraded to have said signal. Or like... Something.... Idk.

That is a link to a PDF from Qualcomm. It even explains the "challenges" of interim networks and the high probability of service loss.
