Choosing the right internet in San Diego
Fiber internet is available in parts of San Diego — if your address qualifies, it's the strongest option on the market. AT&T Fiber offers symmetrical speeds up to 1000 Mbps with no data caps, meaning your upload speed matches your download speed. That symmetry matters for San Diego households doing video calls, remote work, and uploading large files. Check address-level availability before assuming fiber has reached your block in San Diego County.
Fixed-wireless internet from Verizon 5G Home and AT&T Internet Air and T-Mobile Home Internet reach homes in San Diego that lack access to fiber or cable. Rather than requiring buried cable infrastructure, Verizon 5G Home and AT&T Internet Air and T-Mobile Home Internet transmit radio signals from towers near San Diego directly to a receiver mounted on your home. Typical plans run from 100 to 415 Mbps down — sufficient for HD streaming, video conferencing, and remote work. Line of sight to a tower is required, so coverage depends on your exact address and local terrain in San Diego County.
Cable internet in San Diego comes from 2 companies — Spectrum and Cox — with top download tiers reaching 1,000 Mbps. Cable footprints don't always overlap, so which of them can wire your home depends on your street — check your exact address rather than assuming every cable company reaches every part of San Diego County. Across all of them, upload speeds run far below download speeds, which is fine for streaming but can pinch during large uploads or back-to-back video calls.
Starlink satellite internet is available at any address in San Diego, making it a reliable last-resort option for homes where terrestrial providers haven't reached. At $120/month with no long-term contract, it costs more than most wired services — but for locations in San Diego County where fixed wireless and cable aren't an option, the performance improvement over legacy satellite is significant. Expect typical download speeds around 150 Mbps and meaningfully lower latency than older geostationary satellite systems serving San Diego County.
