No phone service necessary. Just down load the app to your phone. The reason I got it for my young daughter she doesn't have to worry about anything. Just put the dot on the animal and pull the trigger.No adjusting turrets or anything to mess with her concentration It even dopes for wind, It works like this. She is on the animal looking threw her scope. I put the wind dope into my cell phone with the Sig App. I hit the button it sends the correct info to her scope. Everything wind ,yardage, angle etc. She just puts the dot on the vitals and squeezes the trigger. In Utah it is not legal to use a scope with a rangefinder inside of the scope.But sense this is a separate rangefinder its okay even though its ran threw Bluetooth. Go figure.
