I currently have an Alltel phone and I am using one of the old Alltel pay per day plans that is only a dollar a day. My alltel phone broke, so I'm wondering if I am able to buy a Verizon phone and active it without having to change to one of the new plans that verizon has. I was planning on buying of the LG keyboard phones, so it's not like I'm buying a droid or anything. So am I able to upgrade to a verzion phone without having to change plans?
