Why cell phone signal fluctuates

Ever wonder why signal bars on your phone go up and then down when you haven't moved?


Signal fluctuation happens with every wireless network and may occur due to several factors:


  • Weather
  • Radio interference
  • Phone software
  • Tower proximity


Phones also some times switch from one tower to another tower without changing location. When this switch occurs, you may notice a change in signal bars on your phone.


Tips to limit signal fluctuation:


  • If you move to another room, or closer to a window, the signal strength may increase and limit fluctuation.
  • If your device supports Wi-Fi Calling and you have Wi-Fi in your home, we encourage you to use this service as a solution.
