- CBSA: 46520 (Urban Honolulu)
- Cable providers: Spectrum

Honolulu's internet market is shaped by geography. All mainland internet traffic travels through undersea fiber cables connecting Oahu to the continental United States, which historically limited speeds and raised costs. Spectrum (formerly Oceanic Time Warner Cable) and altafiber (formerly Hawaiian Telcom) are the two main wired providers, and together they cover nearly all Oahu addresses with cable and fiber respectively.
The large military presence at Joint Base Pearl Harbor-Hickam, Schofield Barracks, and Marine Corps Base Hawaii drives significant demand for reliable home internet among service members and their families. T-Mobile 5G has expanded rapidly across Honolulu, giving military families and renters a portable wireless option that requires no professional installation and transfers easily with PCS moves. The tourism industry also fuels demand, as vacation rental operators need consistent broadband to manage their properties.

Internet Speed Requirements for Honolulu Households
The speed you need in Honolulu depends on how many people and devices use your connection simultaneously. A single person streaming video and browsing the web can get by with 50-100 Mbps. A household of 2-3 people with regular streaming and video calls should target 200-300 Mbps. Larger families with 4 or more heavy users benefit from 500 Mbps to 1 Gbps plans, especially when multiple people are streaming in 4K, gaming online, or working from home at the same time.
Upload speed matters just as much as download speed for Honolulu residents who work remotely. Video conferencing platforms like Zoom and Teams require at least 5 Mbps upload for stable HD video, and 10 Mbps or more for group calls with screen sharing. If multiple household members participate in video calls simultaneously, ensure your plan provides at least 20-25 Mbps upload speed. Fiber plans offer the best upload performance with symmetrical speeds.
