Providers in San Diego
Based on public coverage filings for San Diego. Availability changes block by block, so enter your address on the FCC National Broadband Map before you order.
| Type | Provider | What to know |
|---|---|---|
| Fiber | AT&T Fiber | Widely available. Where fiber hasn't arrived, AT&T may only offer slower DSL. |
| Fiber | Spectrum fiber (former Cox) | In parts of the city, often newer areas. |
| Cable | Spectrum (including former Cox areas) | Cox's San Diego system became Spectrum after Charter's acquisition closed in August 2026. |
| Building fiber & wireless | Webpass, Astound and others in some buildings | Many apartment and office buildings have their own contracted providers. Ask your property manager. |
| 5G home | T-Mobile, Verizon, AT&T Internet Air | No install visit. Speed depends on signal, building materials and time of day. |
| Fixed wireless | Local wireless carriers such as MINTernet, GeoLinks and San Diego Broadband | Roof antenna to a tower. Some sell symmetrical business service. |
| Satellite | Starlink (plus Viasat, HughesNet) | Mostly for backcountry and canyon lots without wired service. |
Coverage filings tend to be optimistic. No prices here, because promotions change too often to keep accurate.
Local notes

High-rises often have building-specific providers in addition to AT&T and Spectrum. Ask the leasing office what's wired before you move in.
Sorrento Valley, UTC and Mira Mesa
Biotech, defense and tech offices often need dedicated fiber, heavy upload and redundant carriers.
Clairemont, Kearny Mesa and North Park
Established neighborhoods where many streets have AT&T Fiber, but some still have only DSL. Ask specifically for fiber.
