@Ed_H.. Hey friend, I know we have touched on things together in the past..
Anyways , your correct dropped calls and service has turned to utter garbage here in the burbs of Chicago... Plainfield here and its horrible... I contacted Sprint the other day and got a one of the uncooperative reps. Got the usual speech... "Were sorry for your inconvenience that you have been having... " The rep was a real "help" he verified that we have good 3g/4g voice coverage here in Chicago.. LMAO....
When I complained about the dropped calls I was told they can offer the Airave.. Again I said great but that doesn't help service away from my home. I told the rep I don't even bother using my phone from home anymore, wife just texts me when she needs to talk and I use the house phone and call her work phone on a competing carrier with good service.
Bottom line, its going to be an uphill battle with Sprint. They know the service is horrible here, I walk into my local store and the reps there are repeating the same speech over and over again to the customers complaining saying how it will be better once the Network Vision upgrade is finished...
