namaskar welcome to beacon TWiki this video is related to my other video called mobile signal booster in that video I explained how you can build a very low-cost mobile signal booster at home by yourself now thousands of people have watched that video and many of them had a very common question how exactly to find out the frequency of operation of an operator in a given area so in this video I am going to tell you how you can do that so let us get started if you have a Samsung Galaxy phone chances are you don't need any third-party app for this purpose you can enter a short code to open up service menu and find frequency band easily navigate to settings mobile networks and choose network mode let's change to LP to find LG frequency man for now now open dialer and enter this code star 1/2 0 0 1 1 hash this will open up service mode here you can see that the phone is currently connected t
