I work for Cellular One and can tell you this. You would need a GSM unlocked phone for that phone to work with Cellular One. I would be very careful as to where you purchase your phone. Most people don't know what unlocked means but to make a sale, I'm sure they will tell you the phone is unlocked. Simply this. Before purchasing a phone from anyone, put your Cellular One sim card in the phone. If it works, then buy it. And above all, stay away from Ebay.
