If you are a Verizon customer and own an Android phone, you can start charging Google Play store purchases directly to your Verizon account. It’s called carrier billing, something we first reported a few weeks back which was then confirmed to be on the way by Google Play.
This new service doesn’t require that you do anything on your end, other than making sure you switch the payment method upon checkout to “Bill my Verizon Wireless account” should you want to rid your life of credit cards. From what we understand, there is a $25 limit on purchases during a billing cycle. So there are some boundaries, but overall, this is a new option for those without credit cards.
If you would like to disable it, you may be able to through this page at Verizon’s site. From there, go under Service Blocks, then “Add” and then check the box for “Block Web Purchases.”
