Or, if you really want to unlock the phone, ask tracfone how many months of service are left on the 12 month contract before they will unlock it, and you could switch to tracfone and keep your same phone number by having them port it from Mint to Tracfone. Then just stay on trackfone for how many months is required to have them unlock it. Or, just sell it and mention to the buyer and in the add that it's SIM-locked to tracfone for "X" number of months. A tracfone user may buy it. This is why I never buy used phones.
