Understanding C Spire's Unlimited with CashBack on your Bill plan

Never worry about data limits with the Unlimited with CashBack on your Bill plan. Not only does the plan include unlimited data* for up to 10 lines, you'll also get unlimited talk, text and free international texting to over 140 countries.
Lines 2-4 are only $50/mo.** Also, for each paid line using less than 2GB data in a month, customers will receive a $10 bill credit on the next bill.
 
To get this plan, you either need to be on a Device Payment Plan or own your device outright.
 
*After 25GB of usage in a month, we may slow data speeds.
 
**The "4th-line free" promotion ended on 4/5/20. Customers currently receiving their 4th line free will continue to do so for as long as they have this plan.
