I am not sure if it my husbands Droid Turbo that is the issue or my iPhone. Since he upgraded to the Droid Turbo he has been intermittently receiving my calls. This is concerning because we have a Verizon tower no more that 100 yards from our back door on the edge of our property. He can receive calls from other phones but only gets about half of mine. Any suggestions on how to proceed? We have already had his phone replaced once.
