Did you know that the lines on the phone that indicate the signal are like shoe numbers from different shoe manufacturers, and that two lines on a Samsung are not necessarily two lines on an iPhone. Anyway. Poor cell signal is a reality for all cell phone brands, and YouTuber Grant Thompson has put together tips for us to improve it.

In our case, we do this not by checking how many dashes we have, but by calling to *3001#12345#. This will send our phone into test mode. In case there is a signal -100dBm or lower, we are in that dead zone, while -70 dBm or better means that our signal is excellent (10dBm difference means that the signal has improved by 10x).
