Alanascott17, we want to ensure you have the answers you need. We also hope you've located the device since your inquiry. There are no impacts to other lines on the account when you suspend a line of service. You can easily suspend and reconnect service as shown here: https://www.verizonwireless.com/support/suspend-service-faqs/. There are no additional charges involved in doing either actio,. When a device is misplaced and you have a smartphone that registered either with Google or Apple, you can use the Google Android Device Manager or Apple Find My iPhone services to emit a sound on the device to locate it. So long as the device is powered on with GPS enabled, those services will locate the device for you (even if the sound is off).
