What does an Sprint Iphone 4s with a bad ESN mean?

I guess the person couldnt make the monthly payments so their phone got cancelled. What does an Sprint Iphone 4s with a bad ESN mean? Can it be unlocked/jailbroken so it can be used with T-Mobile, or is it completely useless?

Just what you said. A phone with a bad esn(usually CDMA phones), are phones that has a balance owed on them or they are phones that were reported lost or stolen. You still can have it jailbroke and unlocked.

  • What really is a bad ESN? Does my situation mean I have one on my IPhone? Do I have a bad ESN? I fully own my phone. I got it through sprint free when I signed up for my plan and we also got a Note 3 for 100 bucks (we paid it upfront ) on the same plan. But we left our provider for AT&T. We did not pay our final bill yet but there's no charges at all for our phones on the bill. So if we fully own our phones, but did not pay the final bill yet (and is way past due in a collection agency… Unfortunately… ), do we have bad ESNs?
  • What does it mean if an iPhone has a bad ESN and can I buy it? My iPhone 5s was stolen and Verizon as usual is not taking any pity from anyone nor would they offer me a replacement at a discount so if I want the replacement I would have to buy it at full price. I looked online on ebay and saw some iPhone 5s that were really cheap selling but when I look it says bad ESN. I read somewhere that you can't activate this with your provider is that is the case. Is this true and what exactly is bad ESN on an iPhone?
