How to upgrade ex-Verizon HTC m9 without a Verizon Sim card?

I paid full price for my Verizon HTC m9 and left their service for different carrier. Now I can not upgrade my phone without a Verizon SIM card. And I can not get rid of their red Verizon screen when ever I turn ON my phone. Plus I can not get rid of Verizon apps.
