I am out of my 700 allowed minutes for my verizon plan and I have about two more weeks in my billing cycle. Can I upgrade right now to a larger plan until my next billing cycle and then downgrade back down to the 700 minute plan when my billing cycle rolls over to the next month?? This was an accidental over usage and won't happen again. Is that possible to do with Verizon so I dont have to pay the 0.45 per minute charge after I go over??
