I got a ipad2 3g for christmas and set up the 3g access with 3 today, I used it for an hour on the bus, downloaded 1 song, and browsed the web, no streaming... its now saying I have exceeded the 15gb monthly limit, could that be right?
The simple answer is no you can't use 15 GB in an hour over a 3g connection.
If you were achieving 3 Mbps and streaming for the full hour,you would use 1.3 GB .
However,a thought struck me,are you on a contract ?
If you activated your account very near the end of a billing cycle ,you would only get a pro rata of the 15 GB.
Have you checked you usage in My3 ?
No possible way you could have used that amount of data. As the other poster says, there may have been a problem with the amount of free data you were given. Sure 3 will sort it out if you give them a shout.
I paid €20 in the shop so I took it that he had signed me up for the month, I found a voucher code (blonde moment), will have to wait til I get home to set it up with the wi-fi.
