Sprint has pulled the plug on its One Up early upgrade program — an offer that gave a $15 per month discount to customers who opted to forgo a subsidy on their new device.

The No. 3 U.S. carrier quietly made the move on Thursday, as it introduced a new set of “Framily” plans. The plans are similar to long-offered family plans but allow customers to get separate bills for their friends and family, ostensibly making it more palatable to be on the same account.

Sprint isn’t totally getting out of the early upgrade business, as the Framily plans include an option for annual phone upgrades.

However, Sprint is doing away with One Up and the discount it offered to those forgoing a device subsidy. Of note, Sprint’s One Up never let customers keep the discount in perpetuity, offering it only during the two years they were financing the cost of a phone.

Sprint was the last of the four major carriers to offer an early-upgrade program, a trend that started with T-Mobile’s Jump program.

A Sprint representative was not immediately available early Monday for comment on the move.
