Price: Optimum starts lower, T-Mobile stays put
Optimum's entry plans are cheap: $35 for 300 Mbps, $45 for 500 Mbps and $55 for 1 Gig with autopay and paperless billing. The catch is the long term. Optimum displays several address-dependent offers, including five-year advertising and 36-month terms. Confirm which offer applies and whether SecureWiFi+ is required. The checked 36-month terms include a gateway at $0 for 12 months before its fee can increase.
T-Mobile costs more on paper at $50, $60 or $70 a month, but its 5-Year Price Guarantee covers the monthly plan price (not taxes and fees). Phone customers save $15 a month, which makes Rely $35 and All-In $55 with a T-Mobile voice line. If you already have T-Mobile for your phone, read whether bundling T-Mobile phone and internet is worth it.
Compare your checkout total
Add any required Wi-Fi package, equipment charges after the introductory period, installation and taxes to the advertised plan price. Ask for the exact price-lock duration in writing; a lower headline price does not guarantee the lowest long-term bill.
Speed and reliability: Optimum's wired connection is more consistent
Optimum's speeds come over a wired line, so they do not depend on cellular signal. Shared cable networks can still slow during congestion. Where Optimum has fiber, the 1 Gig plan delivers up to 940 Mbps both ways, which is excellent for video calls and uploading large files. T-Mobile's typical speeds are solid for streaming and browsing, but they vary with signal strength and network congestion, and uploads are much lower. Evening slowdowns are a known trait of 5G home internet: see why 5G home internet slows down at night and what deprioritization means.
