San Antonio Internet Market in 2026
San Antonio is Texas's second-largest city with over 1.5 million residents in Bexar County and nearly 2.6 million across the metro. The city's internet market has been transformed by Google Fiber's entry, which has forced AT&T and Spectrum to upgrade infrastructure and compete on pricing.
The result for San Antonio consumers is one of the most competitive broadband markets in the state. Three providers — Google Fiber, AT&T Fiber, and Spectrum — all offer gigabit service across significant portions of the city. T-Mobile 5G Home Internet adds a fourth wireless option at most addresses.
San Antonio's mix of historic neighborhoods, military bases (Joint Base San Antonio encompasses Fort Sam Houston, Lackland, and Randolph), and rapidly expanding suburbs on the north and northwest sides creates a diverse coverage landscape. Newer areas on the far north side near Stone Oak and the 1604 corridor tend to have the best fiber availability, while older neighborhoods closer to downtown may still rely on cable or DSL at some addresses.
Top Internet Providers in San Antonio
**Google Fiber** is the headline provider in San Antonio, offering 1 Gbps symmetric at $70/month and 2 Gbps at $100/month with no data caps and no contracts. Coverage has been expanding rapidly since Google Fiber's San Antonio launch, with strong availability near downtown, Alamo Heights, the Pearl District, and parts of the North Side. Google Fiber's pricing has not changed since launch, making it a reliable value anchor.
**AT&T Fiber** is the most widely available fiber provider in San Antonio, with plans from $55/month for 300 Mbps to $180/month for 5 Gbps. AT&T has responded to Google Fiber's entry by accelerating its own fiber buildout. Coverage extends across most of the city including areas where Google Fiber has not yet reached. The 5 Gbps tier is available in select San Antonio neighborhoods.
**Spectrum** provides cable internet across San Antonio starting at $30/month for 300 Mbps up to $90/month for 1 Gbps. No data caps and no contracts make Spectrum the most accessible option. Coverage is near-universal in San Antonio, making it the fallback choice when fiber is not available.
**T-Mobile 5G Home Internet** at $50/month delivers wireless broadband with typical speeds of 100-300 Mbps. San Antonio's 5G coverage is strong, and T-Mobile is a viable primary option for lighter-usage households.
Internet Availability by San Antonio Area
**Downtown and Southtown** — Google Fiber has strong coverage here. AT&T Fiber is also available at many addresses. Spectrum cable is universal. The historic building stock means some addresses may need infrastructure upgrades for fiber installation.
**Alamo Heights and Terrell Hills** — Excellent fiber coverage from both Google Fiber and AT&T Fiber. These affluent neighborhoods near the Pearl District were among the first to get Google Fiber in San Antonio.
**Stone Oak and North Side (1604 Corridor)** — AT&T Fiber has the strongest coverage in this fast-growing area. Google Fiber is expanding here but coverage is still patchy. Spectrum cable is available throughout. New construction in the Stone Oak area typically has fiber-ready infrastructure.
**Westover Hills and Medical Center** — Good AT&T Fiber coverage near the South Texas Medical Center. Google Fiber availability is limited but growing. Spectrum and Xfinity cover the area.
**Far West Side and Helotes** — AT&T Fiber coverage is expanding but not yet universal. Spectrum cable is the primary option in many newer subdivisions. Some rural-adjacent areas may have limited options beyond cable and wireless.
Our Recommendation for San Antonio Residents
San Antonio residents should check Google Fiber availability first. At $70/month for 1 Gbps symmetric with no caps and no contracts, it is the best value in the market when available at your address. Check fiber.google.com for your specific address.
If Google Fiber is not available, AT&T Fiber at $55/month for 300 Mbps or $80/month for 1 Gbps is the next best option. AT&T has broader coverage than Google Fiber and competitive pricing, particularly at the 300 Mbps tier.
Spectrum at $30/month for 300 Mbps is the best budget option and available at virtually every San Antonio address. The no-cap policy makes it particularly attractive for heavy streaming households that want to avoid Xfinity's 1.2 TB cap.
The competition between Google Fiber, AT&T, and Spectrum in San Antonio means prices are among the lowest in Texas for the speeds offered. Take advantage of this by comparing all three before committing.
