Comcast is implementing a data-usage cap in the Lowcountry and Savannah.
According to their website, starting November 1, (September 1 for Savannah) households in the Charleston market with Comcast will be capped at 300 gigabytes of online data per month, with the option of adding more data in 50 GB increments, costing $10 each.
Customers in these areas cannot opt-out of the new data usage plan, but there is a grace period as customers adjust. A new program gives three courtesy months for exceeding the 300 GB in any 12-month period, waiving the overage charges.
Customers will be notified by e-mail and in-browser when they are approaching the data limit.
If customers use less than 5 GB per month, a $5 credit will be added to their bill.
Previously, Comcast capped data usage to 250 GB per month, but didn't charge costumers who went over. Instead, it warned them and threatened cancellation of service.
Streaming one hour of HD video on Netflix or Hulu uses about 1 GB of data, according to their websites.
According to Comcast's website, the average costumer uses 16 GB of data per month.
Comcast says they can change the new data usage plan at anytime without any notice.
Eight other areas across the Southeast are also in this trial plan, including Huntsville and Mobile, AL; Augusta and Savannah, GA; Central Kentucky; Jackson, MS; Knoxville and Memphis, TN.
