I previously had a contract with Verizon Wireless, but terminated my account because I moved overseas (PCSd with the military). I am now returning to the United States for a short time, and I was inquiring if my phone has pre-paid capabilities. When I left the States, I was using an ENVY Touch. Is this phone capable of being used on a pre-paid basis, or would I have to purchase another phone? Thank you in advance!
