Cell phone tapping is possible without any physical activities?

Hi, yes, your cell phone can be taped without you knowledge. I tell you cell phone is simply electronic equipment that transmits and receives radio signals. so to tap all that is needed is a receiver that can receive the particular cell phone signals you want to TAP. Generally digital signal encryption technique is used for tapping. So tapping a cell phone is easy but illegal too unless you are authorized to do that.Most scaring about tapping is that any one with proper equipment can record all your calls and messages automatically without your knowledge that anybody is monitoring you all 24 hours and can make your life miserable using that information against you. That is the reason you are advised not to make any sensitive calls through your cell phone which can bring you in trouble. After all the equipments are made by human and can do any thing beyond your imaginations. All network provider companies can record your calls and no one can identify that your calls are under observations. Tapping is generally used for making investigation against criminals by the authorized people or agencies. Any one does this without authorization is punishable by law.
