I have a Nokia 3595 its got Tmobile To Go on it.. but i recently found an old nokia 5165 that will accept Cingular's Prepaid service which is better due to the fact u can get an Unlimited weekends plan and ur minutes go up at Night so i was wondering instead of using the Nokida 5165 can I get them to put their Sim Card and Service on My Nokia 3595 Is it possible? I thought i would ask here b4 i asked them 2morrow..
