Pros: None that I can think of
Cons: I recently became unemployed, I could not pay my bill for six weeks, until my first unemployment check came. Sprint charged me the early out of contract fee. I called and explained the situation and then Sprint said that they would take back the early out of contract - they never did. I do have my phone back on but the bills keep coming for the early out of contract. My phone is old and Sprint tells me that I cannot get a new phone until May of 2010. My battery only holds a charge for two hours.
Summary: Do NOT go with a Spring account. You can find better with Verizon or AT&T.
