E S N=Electronic Serial Number. It is a hexidecimal number which identifies
along with the I M E I the phone. Without a valid E S N, the cellular
provider has no way of identifying the phone back to the account holder, nor
to the tower. This is how back in the days a lot of phone freakers, got
around paying for service. Quite obviously, I'm not going into how they did
it specifically, nor do I know how/want to know how, but what they'd
basically do is they'd ESN clone the phone. Meaning, they'd figure out
through social engineering or some other form a phone number and the ESN of
a person's phone, then would clone their phone to the ESN of the other
person's phone, thus, basically making their phone become the other person's
phone/phone number. Pretty scarey stuff, if you want my opinion. Not to
mention downright illegal, and God help anyone who tries it!

Hi,
I have seen phones referred to as having a bad ESN, and I wondered what
that
is.
Thanks.
