CenturyLink Features Lower Fees Than EarthLink
CenturyLink Offers Free Self-Installation
CenturyLink offers free installation for most of its internet plans. For subscriptions requiring professional installation, customers can expect to pay a one-time fee of $85. While EarthLink also offers self-installation, it typically still requires an activation fee of $19.95, which includes shipping the modem and a self-install kit. Select plans might require professional installation at an additional cost.
EarthLink’s Contracts Are a Major Downside
EarthLink requires a 12-month contract for the majority of its plans. If you decide to end your contract early, be prepared to face early-termination fees (ETFs) of up to $200 with EarthLink. If you’re looking for internet service without annual commitments, CenturyLink offers internet plans without any contractual obligations.
Data Caps Are Unlimited With Both Providers
No matter if you go with EarthLink or CenturyLink, you won’t have to worry about data caps with either provider. That said, EarthLink does have a soft data cap on its wireless plans.
