I lost my cell phone today and my contract isn't up for another year. Of course I don't have insurance, so a new phone is kinda expensive. My question is, if I buy a phone off of ebay, with no sim card ( since I lost mine ) , will cingular activate that phone even though I didn't buy it through them? I just hate to spend 150 dollars on a phone I can get off of e-bay for 50. Could I buy a sim card from e-bay also and just get them to activate it? Thanks for the replies.
