Sprint's One Up early upgrade plan is no more. With the announcement of the plan last September, Sprint joined T-Mobile, AT&T, and Verizon in offering a way for customers to upgrade their handset mid-contract. Sprint was the last major carrier to offer an early upgrade plan, and it looks as though it's the first to axe its plan as well. Customers looking to discover more about One Up are now being informed that it was retired January 9th, and invited to check out the carrier's new "Framily" plan, which encourages users to link their accounts with friends' to save money.

It's a surprising move from Sprint. In our comparative article on early upgrade plans, One Up fared well, offering a compelling option for those looking to get a new phone every 12 months without the hassle of reselling. The Framily plan can't be seen as a direct replacement to One Up, in so much as it doesn't offer any option for early upgrades without paying for unlimited data first. Whether Sprint is canning the idea of a standalone early upgrade plan entirely or is working up a new offer remains to be seen, but we've reached out to the company for clarification.
