Mobile Data usage
 

Does my data usage stop automatically once I have reached my allowance? I ask because my mobile has been gobbling up data at a huge rate this month despite using wifi, and I notice that my bill is slightly higher than usual. I got the warning that I was running out by text, but turned mobile data off, but it seems that I still got charged.

You'll get charged £2 a day for every day you go over your allowance.
