Should have read the rules first; I apologize. Phone is a Cingular; my SIM card supports AT&T wireless (the old technology) I have a charter membership and upgrading will cause this to change. Current carrier is AT&T (formerly Cingular, formerly AT&T Wireless) I dropped my own phone (NOKIA 3650)in a toilet and all attempts to restart have failed. My son passed away last November and his phone is this NOKIA 6061. When I put my SIM card in his phone I get a message that there is a restriction code on the phone. His wife is certain he didn't have one of his own so it must have something to do with my SIM card in his phone. I hope I haven't muddied the waters here with too much detail. Thanks in advance for any help.
