Docomo 3G datacard
Data usage information

Hi,

2 weeks back I bought new 3G docomo data card. I opted post pay offer, they are not telling how much data I've used till now. They are telling that ' we can't tell that and we don't have that facility!!! ' . I was using mts data card, It has the option to check how much data I've used. But docomo guys are telling we will get in the bill.

What is the Guarantee that they will charge more in the bill?

Thanks,
