I used my mobile sim card in my lap top dongle last month as I was away from home. I have 1 gb of data per month, and have no idea of knowing when I have reached the 1 gb. my worries are that I could have gone past my 1 gb and might have incurred extra charges, my monthly bill was renewed today 10th but when i click on recent usage I can not find out my charges before midnight, is there any way I can prevent this happening ? like automatically disconnected from the internet once the 1 gb has been reached, I have just noticed that an amount under new charges since last bill as there is no usage listed !!!!!
