This is a limited time offer that can be used by new customers, or for new lines activated by small businesses. And yes, existing customers who add a new line can also take advantage of the guarantee. In addition, customers leaving one of the major carriers can still take advantage of Sprint's 50% off plan that cuts your current T-Mobile, AT&T or Verizon invoice in half. And the carrier will even reimburse you up to $650 per line to cover your ETF or phone installment plan balance.
The nation's fourth largest carrier is betting that once you do try its service, you'll like it. Heck, you might even love it. And Sprint is willing to back this up with the 30-day guarantee.
