I have a monthly prepaid plan through Boost and it's expiring today. I no longer want the service at all, and I'd like to sell my phone and be done with it. Is there anything I need to do? Do I need to call Boost to have the phone removed before someone else can use it? Should I sell it with the SIM card in it? Do I have to wait until my account is no longer eligible for reactivation before I can sell the phone? Thanks!
