A:AnswerSo the call quality is attached to how far your phone and Bluetooth is from the actual watch so if you keep it as close as possible I don't know exactly how far away it can be in still work but say even like the next room I would just test it out maybe see where you would need to leave it if that was your concern it's a good idea actually but yeah if you leave the phone close enough where the Bluetooth still connects you'll be okay
