I was trying out a Smart prepaid sim on a hand-me-down Iphone 3GS. Last July 24, I put in a prepaid load of P100. To be sure that I don't accidentally use the load on mobile internet, I have disabled the 3G as well as Cellular Data.
Just now, I found the feature of the Sim Applications and checked my load balance and I received a text saying I have only P10.00 balance.
I have not made any calls nor sent anyone any text messages.
So where did my load go to? Is there a way to find out where it went?
