I subscribe to U-Verse and so I went to see how far off they were with my usage.
The U-verse data measurement report is currently under construction. When completed, you will be notified if your usage exceeds the allowance. Until that time, U-verse customers should not be concerned about their usage patterns for billing purposes.
Wouldn't it be nice to get enough notice to evaluate if AT&T's product meets my needs? Alas, my router tells me I've used 230 GB over the last month; that's pretty close to their 250GB limit, and if the numbers are 'fuzzy' then all bets are off.
Because U-Verse TV service is IP-delivered, I'd like assurances that they're not including this traffic in any metering - I'm already paying for this content and its delivery on the 'TV' portion of my bill.
