Vortex 4G Phone- Prepaid plan -Unlocked - Model: SYNQ

Description

Won this phone in a locker auction. No password required. Phone unlocked. Able to make calls and use the internet with Cingular connection. No contacts or personal data on phone. I think this may be prepaid plan? I made call with this phone weeks ago and it still works today! I have no idea how long the free Cingular plan lasts for, but phone appears to be new. I can only find one similar phone on eBay and seller is a asking for over 00...what am I missing?
Putting phone up for auction. I’m not sure if this is worth , a 00 or somewhere in between and will find out with this auction. Happy bidding!
