I faced an issue with DiGi's GPRS Pay per usage and is now having bill shock for two months. Been using my iPhone for almost 10months and this is the first time such issue happened.

Here's the status of my iPhone:
iPhone 3G 16gb 3.1.3
Jailbroken without Carrier Update
SBSettings turned off Edge already,
3G turned off,
Cellular Data Network's settings are all blank.

OMG the bill was like three times of my normal usage..but the question is how can iPhone uses GPRS while all those settings are taken to prevent usage?

Anyone help? I had called DiGi and tried to make a report as well as escalating the issue to billing department (i think is their usual routine)..

@johnny12262711: How can you connect when you are disabled to use that services? But have you tried to disable the settings in your iPhone? Or it is not effective?

It seems that my case was similar to yours..but when there's no settings what could possibly be the reason that caused iPhone to connects? Or is it that telco trace your usage by how many data request you made regardless of whether you have the settings right or wrong?
