Just to mention, with my Note 3, I have never had this problem; for the record, I am on att and have great lte coverage. Daily, I use data and voice simultaneously and never a dropped connection. Also, no one has ever told me that they called and it not being in the logs. Going on 8 months usage.
Sounds like a location problem with no easy resolution.
I agree - I think its going to be a location deal. I'm going to try Kelly's suggestion about getting a micro cell. I hope that works!
