how much does it cost to browse the web on virgin mobile jax?

Depends. If you have no plan. $1.50 a day a meg. If you use up a meg in a day, you will be charged for another one.

There are 5, 20 and 50 meg plans which vary in price .

If you have a pay go plan, it costs more then a monthly plan.

For example on the Paygo the 50 meg add on is $20. On a monthly plan it is only $10. But Paygo plans give you minute rollovers , monthly plans, if you don't use it in one month, it is gone.

There is no rollover. You don't use the whole meg once activated in 24 hours, the leftovers disappear.

A meg is about 100 regular page views on the mobile web without anything fancy like streaming video or audio or whatever.
