My family has been a Verizon customer for probably 10 years or more. Cell phone service inside our home has never been good but in past was always able to go to certain areas of house and make and receive calls. Within last years I was able to switch my cell phones to WiFi calling and that fixed my in house calls . Up until recently when outside my house in yard/garden service was weak but always was able to make and receive calls , but now most of the time ‘no service’ or ‘SOS only’ when in yard/garden . What has caused this? What can you do to get my coverage back?
