T-MOBILE TO START CHARGING DATA OVERAGES ON AUGUST 14TH

T-Mobile, flooded by larger-than-expected demand on data, may be just a matter of days away from making a polarizing change to its 200MB internet plans. As the feature currently stands, going over your limit results in a throttling of broadband speeds, forcing your browser to surf and download at a ridiculously slow pace. The rumored adjustment to the plan, however, would take away the option completely and replace it with usage charges. Each additional MB used, according to the leaked docs, will tack an extra dime onto your monthly bill.

Fortunately, the overage is capped at $30 -- preventing several potential panic attacks at the mailbox -- and only affects the lower plan; additionally, anyone currently on the 200MB plan will be grandfathered, thus retaining their unlimited (albeit throttled) internet. Those on the 2GB plan can breathe easily for now, but there's no telling when the policy will spread like wildfire throughout the remainder of T-Mobile's data offerings. The change, slated to take place on August 14th, has yet to be officially confirmed.

AT&T TO THROTTLE SMARTPHONE DATA

AT&T said on Friday that it will begin throttling unlimited smartphone data plans as of October 1st. “Like other wireless companies, we’re taking steps to manage exploding demand for mobile data,” AT&T said Friday in a statement. The carrier continued, “One new measure is a step that may reduce the data throughput speed experienced by a very small minority of smartphone customers who are on unlimited plans – those whose extraordinary level of data usage puts them in the top 5 percent of our heaviest data users in a billing period. In fact, these customers on average use 12 times more data than the average of all other smartphone data customers.” AT&T was very careful to mention, repeatedly, that the new move will not impact the “vast majority” of its customers. According to the carrier’s statement, only the top 5% of its smartphone data users will be affected.

VERIZON WIRELESS LAUNCHES NEW THROTTLING SYSTEM

Verizon Wireless is launching a new network management and throttling system today. The company says that these practices include caching less data, using less capacity, and sizing video content "more appropriately" for smartphones. But according to the memo, the new system (which not coincidentally arrives with Verizon's launch of the iPhone) also involves throttling data throughput using a new "proactive management" system that Verizon claims will only impact the top 5% of wireless broadband users:

Verizon Wireless strives to provide customers the best experience when using our network, a shared resource among tens of millions of customers. To help achieve this, if you use an extraordinary amount of data and fall within the top 5% of Verizon Wireless data users we may reduce your data throughput speeds periodically for the remainder of your then current and immediately following billing cycle to ensure high quality network performance for other users at locations and times of peak demand. Our proactive management of the Verizon Wireless network is designed to ensure that the remaining 95% of data customers aren't negatively affected by the inordinate data consumption of just a few users.

Unfortunately, Verizon doesn't specify what kind of consumption you need to be guilty of to find your connection throttled. [BGR]
