I am using a "smart prepaid" data plan costing $19.00 a month on my phone.
What I am finding is that I am running out of data towards the end of the month so I top up with additional data pack.
Now I do not want to go on the $29.00 plan as it is not every month that I need to do this.
However what is happening is that my balance (cash) is running down when my data runs out.
I presume I am being charged for mobile data before I get a chance to purchase a data pack.
Is there a way to stop this happening ?
