Prior to January/February 2024 I had little or no issue with phone calls. Since then there is a growing issue with phone calls randomly dropping out - this morning one call dropped out twice with a known caller who lives within 6 miles of my home. I have noticed that since February 2024 signal strength has been 1 or 2 bars whereas pre-February '24 3/4 bar signal strength was the norm. It is as if a local 'booster' station has gone down.
There are no issues away from the home area, even hands-free in the car is good.
A mystery??
