As a matter of fact I have an auction for an Unlocked Sony Ericsson T616 (originally with ATT) and I have used it with many carriers and it works just fine. There are no repurcussions and this way you do not have to sign up for a new 2 year contract. E Bay is a great source for used and new GSM cell phones both locked and unlocked. My auction ends at around 6.40 PM EST, if you search I am sure you will see mine and many more similar ones.
Sorry if this topic has been beaten to death. I've read through a few of the related discussions, but my situation is kind of unique.
Yesturday, i went to a Cingular Wireless distribution stand to just upgrade my crappy motorola AT&T phone to a new Samsung camera phone. I found out that i was under a Corporate Discount program, since my dad works at Fidelity Investments. Also i'm in a family plan which means everyone in my family has the same phone, # of minutes, etc.. Apparently the salesman was unable to "touch" my account, period.
I was just wondering if i could purchase an unlocked AT&T phone off of ebay and just replace it with my old phones SIM card and be GOOD TO GO without any repurcussions.
Thanks in advance.
