LG Optimus V: Check ESN before Buy a Used One

Each cell phone has a unique id programmed by the manufacturer, that is either Electronic Serial Number (ESN) or Mobile Equipment Identifier (MEID) depending on the the phone. Please save that number to a secure place right after you get your phone fresh out of the box.

This number is very useful. You need ESN to activate your phone with the service provider before you start to use it. You can also lock that phone if you found out that you lost it. All you need to do is to call the service provider and give them the ESN. This turns that specific phone into a brick. So whoever stole it can't use it.

There are lots of used LG Optimus V on sale online. Some of them marked pretty cheap for quick sell. You must be careful when you buy those. They could be a stolen phone or a  phone with service blocked. The easiest way to make sure that the phone is worth the money is to check if the ESN is a good one.

Here are the web sites that you can go to check the ESN numbers.
