The telecom company, Comcast, is readying itself to launch a new policy that places data caps on home internet usage, reported Yahoo Finance. This is the newest telecom hustle designed to overcharge customers and increase profits.

According to the new policy, customers who exceed 300 GB a month will have to pay overage charges of $10 per 50 GB tier. If customers want capless internet service, they have to pay $30 more a month. High-definition and video streaming are becoming more common and require more data usage, especially as more people are getting rid of cable subscriptions. With that trend, internet companies see an opportunity for more money.

Comcast sent an email to its customers in select areas:

We’re writing to let you know that we will be trialing a new XFINITY Internet data plan in your area. Starting October 1, 2015, your monthly data plan will include 300 GB. We will also trial a new ‘Unlimited Data’ option that will give you the choice to purchase unlimited data for $30 per month in addition to your monthly Internet service fee.

Comcast said the changes are just a trial, but it’s obvious that they will become a hardline policy. Comcast will implement the changes in Huntsville and Mobile, Alabama; Tucson, Arizona; Fort Lauderdale, the Keys and Miami, Florida; Atlanta, Augusta and Savannah, Georgia; Central Kentucky; Maine; Jackson and Tupelo, Mississippi; Knoxville, Memphis and Nashville, Tennessee; and Charleston, South Carolina, reported Yahoo.

The major telecom companies hold a monopoly over internet usage and use that power to hit customers with endless hidden charges and overage fees to increase their profits.
