Does anyone know if it is possible to use an upgrade credit on a line to cancel another line? I have a family shared plan with 4 lines, I need to cancel 2 of the lines. One of the lines I need to cancel is still under contract, but the other is not.
No, I'm sorry, the upgrade credit can only be used towards the purchase of an upgrade. You can visit www.sprint.com/etf to learn more about early termination fees as they are on a sliding scale - the lesser number of months on the contract, the lesser the termination fee.
