AT&T is launching a new set of parental controls dubbed Smart Limits, which will cost $4.99 a month. “They will let parents block text messages and calls to and from specific numbers and also during certain times, like when kids are in school. In addition, parents can filter access to certain content on a child’s phone—such as chat and dating Web sites” reports WSJ. It’s the standard controls—setting times when services can be used and putting a limit on how much can be spent. The article also notes instances when parental controls stop working (which could be of interest to a few kids)... for example, controls in the iPhone won’t work when it’s using a WiFi network, and Disney Mobile’s parental controls sometimes don’t work when the handset is roaming outside the Sprint-Nextel network.
