I am currently on a topup R100 contract on MTN on a blackberry. My fee per month includes the phone, R100 airtime a month, 25 sms's and BIS - "worth" R59 a month - so the full BIS service, not one of their silly, email only etc. ones.
Up until a few months ago I was happy. But recently it seems like money keeps trickling away from my balance. Even if I don't call or anything airtime still disappears. I know MTN charges for some data - apparently certain apps use data. But the only apps i really use are whatsapp and twitter for blackberry. WHY does my data disappear. Even occasionally if I browse Facebook through the webbrowser it uses data?? wtf
