Can I use a verizon Iphone 4 with a bad esn on Page Plus?

I know some people say that this isn't possible, but I have activated 3 iphones for people on page plus. All had bad esn's. All of the phones were originally through verizon, and for whatever reason had a bad esn. If this isn't possible, why did they let me do it? Just a little confused

"Can I use a verizon Iphone 4 with a bad esn on Page Plus?" Yes, but not legally. The phones have bad ESNs for a reason: they belong to someone other than the person holding them.
