Hi! I was going to buy this auction: http://cgi.ebay.com/T-Mobile-Prepaid-Account-78-Balance-Phone-Refill-Card_W0QQitemZ230332264621QQcmdZViewItemQQptZCalling_Cards?hash=item230332264621&_trksid=p3911.c0.m14&_trkparms=72%3A1205%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318%7C301%3A1%7C293%3A1%7C294%3A50 Item # 230332264621 on ebay I contacted the seller and they said I could change my area code by calling customer care and telling them the zip code I wanted my area code in. Is this true? Thanks! T-Mobile.com has a $20 phone that is a piece of junk for prepaid. I have my own phone and I will just put the sim in.
