Optimum plans at a glance
Our verdict
Optimum, owned by Altice USA, sells internet across the New York tri-state area and the former Suddenlink markets in Texas, Arkansas, Louisiana and beyond. Most of the network is "fiber-powered" cable, with 100% fiber where Optimum has built it.
Current prices are $35/mo for 300 Mbps, $45 for 500 Mbps and $55 for 1 Gig with the $10 AutoPay and paperless discount, plus taxes and fees. New customers get a 1-year price lock, or 3 years if they add SecureWiFi+ for $10/mo. After that, the price can rise by up to $15/mo a year until it reaches the standard rate.
Optimum's 60-day money-back guarantee, and its promise to pay to switch you back if you're unhappy, take a lot of the risk out of trying it. On cable tiers, uploads are lower than on fiber, so check which one reaches your address.
