I’m so sorry to learn of the demise of your phone. We’ll lead you through this difficult time. Our fingers are crossed that you maybe have it insured, and if so you can start a claim here https://phoneclaim.com/verizon/
If unfortunately there is no insurance to fall back on, then log into your My Verizon account here https://www.verizonwireless.com/my-verizon/ . Under "Devices" you’ll be able to pay off the remainder of your broken phone before upgrading to something new. Let us know if there are any questions on this.
