Wireless carrier AT&T appears to be completely retiring two-year contract subsidized phone plans. According to leaked employee documents, effective January 8, 2016 the only purchase plans that will remain are full-price purchases, or installment plans through the AT&T Next program. This casts a pallor over existing unlimited data-plan holdouts, as any transition to AT&T Next invalidates the older contract with the unlimited data, leaving only full-price purchases of devices as an option.
