I recently bought an LG G3 off a guy on craigslist. He told me it was used however he switched to a different plan. I know I'm really stupid, but I bought the phone without checking the ESN. I got home and there was no connection to the phone and I could not activate it. I texted my seller and told him the story. He told me that he would fix things up and after 15-20 minutes, I started to get connection bars on the phone. I have a different phone number on it and multiple numbers have texted me, but I can't read the message. Is it possible that he just did not completely disconnect the phone? I can not make calls or texts with it, but I do see that I am getting connection. Does a bad esn still mean you can get connection on the phone?
