Allowing customers to upgrade their phone once every 12 months without having to resell their device, Sprint One Up was promising. Sprint was the last major United States carrier that joined the early upgrade phenomenon, yet is now the first one ending the promotion. Sprint has announced that their One Up program is no longer being supported for new or existing customers, nixing the idea of upgrading a cellular phone by accepting a new installment agreement. Individuals who took advantage of the program before or are currently interested in Sprint One Up are being referred to the newly announced Sprint Framily plan. While the Sprint Framily plan does save money for customers by encouraging them to link their account with family and friends, it is not a direct competitor for the One Up program that is now retired as of January 9, 2014.
