I am having the same issue with my 6s Plus. Verizon keeps asking me the same silly questions as above. The answer is that it happens all of the time all over the place. I think the real answer is that the Verizon system can't really handle LTE in most areas (even happened to me sitting in traffic in Manhattan on the West Side Highway (i.e. clear signal). I assume that Verizon has its best equipment in mid-town Manhattan. The answer seems to be that you have to go to "Settings" and where it says "Enable LTE", you have to choose "Data Only". So, the illusion of being able to to talk on the phone and use your data is only a fantasy right now. Eventually, Verizon may be able to provide that, but not now. Also, the other issue is that, if you are talking through LTE and the other cell phone is NOT an LTE phone, it will drop calls frequently. Even if it is LTE to LTE and one phone has a "marginal" signal (which will happen all the time in the middle of the call), the call will drop. So, forget LTE phone calls for now. See Verizon, was that so hard? Did I really have to go to 4 useless store visits, get a new SIM card, reset my phone 3 times, suffer many phone calls to your tech service, and go through the nonsense of you sending a roving tech to my hometown to "check out" my signal strength? You know the answer (or, at least you should), so just tell us that.
