Either way people will always have a loss when it comes to selling their own phone to buy a new one. I will be going forward going to sim free and buying my phones. I will lose about maybe 350-400 pounds each year but if it's lasted me well for a year then it's done it's job.I never have regrets about selling my phone. If I get $50 or $100 less, I don't care. If that little bit of money is critical to me, then I should not be buying a new phone.
