Sprint has just launched a promotion to entice customers from other carriers. Sprint is currently ranked 4th of the big 4 carriers and this move may raise some eyebrows. Sprint is offering one full year of service with unlimited talk, text, and data. Eligible customers include individual plans as well as family plans from Verizon, AT&T, and T-Mobile. Current Sprint customers are not eligible, although I am sure there is a way to get around that by switching carriers.

Also, you must own an unlocked phone that is on their list:

Eligible Phones

• Apple iPhone 5C (Verizon only)
• Apple iPhone 5S (Verizon only)
• Apple iPhone 6
• Apple iPhone 6 Plus
• Apple iPhone 6S
• Apple iPhone 6S Plus
• Apple iPhone 7 (Verizon only)
• Apple iPhone 7 Plus (Verizon only)
• Apple iPhone SE
• Google Nexus 5 (Verizon only)
• Google Nexus 5X

• Google Nexus 6P
• Google Pixel
• Google Pixel XL
• Motorola E4

The only catch I could find is that they will do a credit check and you have to pay for the sim card(s) as well as taxes and fees every month. Once the promotion ends, you will be on Sprint's unlimited plan which starts at $60 a month for 1 line. The question is will this get customers to switch to Sprint even if it is free?
