I have 2 iphone 6's. have been experiencing dropped call, dead spots in the home and calls where we can hear but they can't. This was never an issue with our other phones our our sons 5s. We live in area code 85086. Becoming very frustrating, please

What I would do is reset the networking settings on each iPhone.  You can do this through settings > general > reset > reset network settings.
