I'm in a plan with Optus and I think i have internet on my mobile phone but i'm scared to get a massive bill. I can go on the internet it dose work but i'm worried to get charged and i'm not sure if i can use it as part of my plan. Is there a way i could find out if i have for example 100MB a month as part of my plan? or dose it come of from my normal phoning and sms credit?
how do i find?
