Common causes: distance from the nearest tower (0.5 mi from city center), terrain, tall buildings blocking line-of-sight, or dense foliage. Indoor loss is especially common — concrete, metal roofing, and energy-efficient windows reduce signal 50-90%. Position yourself near a window facing the nearest tower.
Three options: (1) Use FindTower to locate the nearest tower and orient toward it, (2) install a cell signal booster to amplify weak outdoor signal indoors, or (3) enable Wi-Fi calling to use your internet connection when cell signal is insufficient.
