Sprint plans to go after AT&T and Verizon customers with an aggressive and enticing campaign. Beginning Friday, Sprint will offer rate plans to AT&T and Verizon customers that are half what they're already paying. For example, an AT&T customer who pays $300 per month will be offered a comparable Sprint plan that costs only $150 per month. The offer only extends to the service costs, including minutes, messaging, and data. It does not include subsidies for device payments. Sprint will waive activation fees and pay up to $350 to cover the ETFs of those who switch, though the new customers will need to turn in their old devices. In order to score the half-price plan, new Sprint customers will need to buy a device from Sprint at full retail price or finance it through Sprint Easy Pay. They'll also have to provide a copy of their most recent wireless bill for verification of the monthly cost. Sprint CEO Marcelo Claure hinted via Twitter that the company intends to "launch one of our most exciting promotions ever, especially designed for Verizon and att customers who love to save money." The promotion does not apply to T-Mobile or current Sprint customers.
