I am a cell c customer who is currently drawing nearer to my upgrade window which will start in march. I am on a casual chat 100 and i'm paying R69 for a nokia 6300. I would like to upgrade to a 5800 expressmusic but i am uncertain me how much my monthly payments will be. I can't afford to pay too much as i am only a high school student. I would like to stay on a casual chat contract, how much do u think my monthly payments will amount to after the upgrade or how much will i have to pay-in cash? Thanks in advance
