Unlike the many internet service providers that raise prices significantly after a promotional period (typically a year), CenturyLink lets you keep your initial pricing.Internet speeds available through CenturyLink plans range from 12 Mbps to 1 Gbps (1,000 Mbps). Which speeds are available to you will depend on where you live. A 1-terabyte data cap limits how much you can download per month, although it would take heavy internet use to come close to that cap.Your available bandwidth depends on the infrastructure in your area, with the highest speeds typically available in or near large cities.CenturyLink also includes Norton CenturyLink@Ease Basic, which gives your computer internet security benefits.The company also has television and phone offerings available, which you can bundle in special offers.Customer ServiceCenturyLink customers don't have a high opinion of the customer support offered by the company.
