I recently moved to a new home that is only 400ft above sea level & part of a major metropolitan city (Seattle 98106). The reception at my home is tereble. Contacted tech support & they were able to duplicate the problem but cant do anything about it. I later contact them again & a tech guy advised me to get a phone that takes a sim card. Would a sim card helps in reception? Phone is a D1 on Verizon, thanks.
