I got bit with my 3g router.
Not by much, about R300 over the actual bill.
Anyone know if I can get the warning sms's sent to a different number?
Yes but just remember that it is delayed.
I had a contract 3G setup on my wife's work PC with a small cap. It was enough for daily admin and emails. Thank goodness I added in some monitoring and hard capping on the physical PC (its a Linux machine) the day one of the staff started to watch Youtube while my wife was at home.
The notification from Vodacom only came in hours later.
We switched to prepaid after that but I now have a TopUp Data contract from Vodacom. Works much better as now I no longer need to worry about the OOB shark.
