Need a cheap cell-phone plan.

[7idl]

tell me more about this adding of another line to your phone... added cost per month?

i just got my grandmother on with my plan about a year ago, only $10 to add to my sprint plan, phone was free. mine doesnt use that many minutes so its little or no efect on my minutes.

Already did.... it was $10 a month ($9.99 anyway)

well you didn't specify the terms, only that it cost $10.

My dad wants one for his cross country travels for emergencies and that's it. I'm exploring options.
