hurm.. i am also wondering why my credit is depleting so sudden.. Is it because of the auto connect to internet.. these are my settings:
In Start/Settings/ Connections:
1) in advance network:
-HSDPA - Disable
-SMS service - SMS over :GSM only
2) in Comm manager
-Data connection - off
3)in connections
-advance/select networks - all set to my work network
I dun think there's anything wrong with this settings. However, I noticed that in the HD Tweak Program, under root number 6, there are settings for DATA(GPRS/EGDE/HSDPA)
As I use digi, i now set as below:
6.1 Disconnect after : 10 seconds
6.2 Always on Digi MMS :Disable
6.3 Always on Digi GPRS : Disable
6.4 Always on Digi Internet : Disable
6.5 Enable Digi MMS : Enable (sumtimes I use it)
6.6 Enable Digi GPRS : Disable
Enable Digi Internet : Disable
I am giving this setting a try and monitor my credit balance. Hope that it works.
NOTE : Whenever i have to use internet, thru telco provider, I have to change these settings again.. Which is not frequently use.
