Hi, I am thinking of switching and purchasing to a Verizon "Pay As you Go" Plan. Example: Say I purchase a $100 of prepaid that will expire in one year. Say, after 6 mths of "Pay as you go " usage, my balance is $50 and I decide to switch to a Verizon 2-yr contract plan with 6months left on the "Pay as you Go". WIll that remaing $50 balance be credited to my new 2-yr Verizon contract plan? Thank you.
