I have no clue why it took so long for this to happen. With the types of cellular communication we are all commonly using today, it’s rarely clear how much data or how much of a provider’s service you are using at any one time. Obviously customers should pay for what they use, but there needs to be a lot of transparency about what exactly that means.
Since phones and data devices are based on software, which is easily flexible enough to accommodate new reporting and alerting needs, there just isn’t any excuse for this requirement to have taken so long.
Kudos to the F.C.C. 🙂
