Increasing cell VOICE reception
I have an iPhone 5s with service provided by Verizon. In my home office, my wifi works fine thanks to my router. However, I have difficulty during phone calls because the signal apparently isn't strong enough (voice transmission breaks up such that a few words are missed, although calls aren't dropped). I cannot relocate my office within my home, and the amplifiers/boosters seem geared toward data and not voice. SO...is there an affordable booster or whatever that will increase mobile call quality? Thanks.
