Wait until subscriber goes on vacation.
Subscriber goes on vacation for a month and that month is the same as the measurement period. The customer finds that they have used 35GB of data when they were not even home. Of course AT&T-Mobile will claim that someone stole their bandwidth. Complaints will fall on deaf ears since the lawmakers ears will be filled with campaign contributions graciously provided by AT&T-Mobile. LOL Subscribers!
First off its AT&T, Inc not your "clever" AT&T-Mobile.
Second, it's AT&T IS (Internet Services) who deals with DSL & Uverse.
Third, AT&T Mobility is the wireless/mobile phone divison, which has zero to do with this UBB issue.
Lastly, the company will never be called AT&T-Mobile, it will remain as AT&T, Inc a holding company of the affilated company's previously purchased/merged with.
