I just activated a new pre-paid phone with no problem, my question is when I activated phone it came with 10.00 credit, i then added 15.00 more to account. This ran the exp date out 2 months. The next day I added 20.00 to acct but the exp. date did not change. I thought that a 15.00 purchase runs date out 30 more days, so I figure I should have 90 days to use my credit. All these purchases were made on-line with credit card at verizon web-site. Once I get this figured out, can you run the time out more than the 90 days ( Trac-phone the more you buy the time keeps running out depending on what min card it is )
