Top 3 Apps That Improve iPhone Signal Reception

Why you have bad reception?

Almost all of us have the experience that has little or no cell reception. The weak reception can drive us crazy in certain crucial situations like download or upload important document. There are two main causes for bad iPhone signal.

  • You are too far from the signal source, we say, cell tower.
  • There are things between you and the tower that are blocking the signal.

You can find your iPhone signal strength using filed test mode. It works for iPhone 5 and higher models running iOS 9 or later. Firstly, please navigate to Settings > Cellular > Cellular Data Options > toggle Enable LTE status to Off. You can turn on this option again after viewing the dBm reading. Now follow these steps to put your iPhone, iPad in Field Test Mode.  

  • Dial *3001#12345#*
  • Press CALL
  • Hold the power button until you see the “slide to power off” screen.
  • Do not power off the phone, instead, hold the home button for about 5-7 seconds.
  • You will see the dBm reading at the top of your screen.
Tips: Cell phone signals are radio waves (the AM/FM kind) and operate at a frequency of -50 to -110 dB. -50 dB is great signal, full bars. -110 dB is poor signal, a near dead zone.
