Doesn't sound good, also mailed them the other day. They only said that this function is currently not available. Cell C now sells routers with no USSD support AFAIK. How do they expect customers to check usage when the router is in the roof?Well I've mailed (Tell Trevor) Cell C regarding this and they phoned me back and informed that they might consider it.
I would suggest that everybody who needs this functionality mail them so that we can get the ball rolling.
We need to start pestering Cell C for this. Come on Cell C!
