手机esn不可用怎么解决

If you’re in the market for a cellphone, especially a used one, you’ll hear a lot of talk about ESNs with an emphasis on whether or not the phone is “clean”. What exactly does acronym stand for and what does it mean if the phone is clean or not?

Dear How-To Geek,

亲爱的How-To Geek，

I’m recently out of contract with my cell carrier and I really don’t want to get back into a lengthy contract just to upgrade my phone. As such, I’ve been searching eBay and Craigslist for used phones I could add onto my account without getting stuck in another 48-month contract. One term that comes up in just about every search is “ESN” and sometimes “MEID”, and always in the context of whether or not that thing is “clean”. This is the first time I’ve done anything other than just walk into the local cell store and sign some paperwork to get a new phone, so I’d like to do this smart and not end up with a phone that doesn’t work. So what’s this clean ESN business and how do I make sure I’m getting a good used phone?

我最近与手机运营商没有合同，我真的不希望为了升级手机而重新签订一份冗长的合同。 因此，我一直在eBay和Craigslist上搜索可以添加到我的帐户中的二手电话，而不会陷入另一个48个月的合同中。 几乎每个搜索中都会出现一个词，即“ ESN”，有时甚至是“ MEID”，并且始终取决于该事物是否“干净”。 这是我第一次做其他事情，而不仅仅是走进当地的手机商店并签署一些文书工作以购买新手机，所以我想做到这一点，而不要以无法使用的手机告终。 那么，这是什么干净的ESN业务，如何确保我得到一部二手电话呢？

Sincerely,

真诚的
