Cell phones can be a blessing but when they ring at the wrong time it can be a real problem. This is especially true when they ring in the middle of a performance. Remind people to put their cell phones on vibrate mode with several large signs from Sign.Builders. You can create your own customized Silence Your Phone signs online using our professionally designed templates. Place a Please Put Your Phone on Vibrate sign at every entrance to your building or at strategic locations and enjoy the performance knowing it won't be interrupted with ringing cell phones. Create your sign and select what size and type of material you'd like it printed on and place your order. Your custom sign will be shipped to you within 48 hours (or sooner if you select rush service).
