In my area, I don't see how they can be the low-cost carrier. All of their phones are over $100, $150 for a decent one, so even with a $50 mail in rebate, that's still ~$100. AT&T & Cingular both offer the popular 3360 for ~$50, and 5165 for free. Sprint's $39.99 plan includes only 350 anytime minutes; Cingular gives you 400; AT&T gives you 600 w/ a 2 year agreement on TDMA, and if you are willing to put up with a small coverage area (DFW metro) and sign a 2 year agreement, you get 750 minutes on GSM - and AT&T's N+W start at 8 pm, beating the other two. The only reason I could see that Sprint would be the cheapest would be if you traveled only to major cities, like most people do. You get to use your minutes out of your normal bucket - be wary of analog roaming. But Verizon is being very competitive with their AC plans in this regard - $35/month gets you 300 minutes, $5 less for 50 less minutes than Sprint, and more coverage area. Cingular, beating both of them, will give you 350 anytime true nationwide (no roaming anywhere) minutes - for $40/month. So in this regard, how is Sprint the low-cost carrier? Is Sprint going to change their plans/pricing structure soon to compete with the others?
