I have used Verizon for years and always been happy with reception and service. A few months ago my daughter bought an iPhone7 and does not get good reception in her home (lost calls, static, etc). She previously had an iphone6 with no problems at all. Because she has never had issues she returned the phone to Apple and exchanged it for another iphone7 but has the same issues. I don't understand and don't know what I can do about it. We live in zip code 44057.
