Stand on almost any residential street in Houston, Dallas, San Antonio, Austin or Fort Worth and you face the same three-way choice: the AT&T box on the pole, the cable line (Xfinity in Houston, Spectrum nearly everywhere else) and a 5G gateway in a neighbor's window. The right answer turns on one question: whether the AT&T line is fiber.
Our pick for most Texas homes is AT&T Fiber. AT&T reaches more addresses than any other provider in the state, and where the line is fiber it is the fastest and steadiest of the three. We rank on widest availability first, technology second, fiber ahead of cable ahead of 5G ahead of satellite.[1] If the AT&T product at your house is Internet Air, cable moves to the top and 5G becomes a bargaining chip.
Which internet providers cover most of Texas?
Fiber at 100/20 Mbps passes a bit under two-thirds of Texas locations and cable close to four in five. Only three names cover most of the state: AT&T, T-Mobile and Verizon. Spectrum reaches many areas, as does Xfinity, concentrated in greater Houston. Nextlink, Rise, Optimum, Frontier and Astound each serve some of the state.[1]
| Provider | Type | Where it's available | Contract |
|---|---|---|---|
| AT&T | Fiber, with Internet Air fixed wireless elsewhere | Across most of Texas | No annual contract[2] |
| T-Mobile 5G Home Internet | 5G fixed wireless | Across most of Texas | No annual contract[3] |
| Verizon 5G Home Internet | 5G fixed wireless | Across most of Texas | No annual contract[4] |
| Spectrum | Cable | In many areas (Dallas–Fort Worth, San Antonio, Austin, El Paso) | Not stated[5] |
| Xfinity | Cable | In many areas (Houston metro) | No annual contract[6] |
| Nextlink Internet | Fiber in select areas, fixed wireless | In some areas (North Texas, Fort Worth suburbs) | Not stated[7] |
| Frontier | Fiber where built, older DSL elsewhere | In some areas | No annual contract[8] |
Starlink, Hughesnet and Viasat reach almost everywhere, and west of the Pecos they may be the only option; Starlink starts at $55 a month.[9]
How do I choose in Houston, San Antonio, Dallas, Austin and Fort Worth?
Houston is the one big city where Xfinity is the cable company, and it passes nearly every home. AT&T reaches three in four, but fiber is at only a little over half of addresses, so many "AT&T fiber Houston" searches end in Internet Air. If AT&T Fiber is built to your house, choose it; otherwise Xfinity's $45 for 300 Mbps, held five years for new customers, is a strong second.[6]
San Antonio has more fiber than Houston: almost three in four homes. Spectrum is the cable line, AT&T the fiber line, and Google Fiber reaches about a third of the city at $70 for 1 Gig with no caps or contract.[10]
Dallas sits between the two. Spectrum is near universal, AT&T reaches three in four homes, and fiber passes about six in ten.
Austin is Google Fiber's biggest Texas footprint, more than four in ten homes, alongside AT&T Fiber and Spectrum.
Fort Worth is quietly the fiber capital of the big five: three in four homes, AT&T nearly everywhere, and Nextlink building fiber across the suburbs at $30 a month for 500 Mbps in year one.[7] Spectrum's reach is lower here than in Dallas.[1]
Is 5G home internet a good choice in Texas?
Yes, more often than in most states. Licensed fixed wireless at 100/20 Mbps covers about six in ten Texas locations, the same share as fiber, and T-Mobile and Verizon each reach most of the state. T-Mobile's Rely plan is $50 a month with AutoPay, or $35 with a T-Mobile phone line, unlimited data, no annual contract.[3] Verizon 5G Home is $35 a month with a Verizon mobile plan.[4] AT&T Internet Air has unlimited data and no annual contract.[2]
The limit is upload and consistency. A gateway with a clear line to a tower can match cable; the same gateway in a dense Dallas complex at 9 p.m. may not. Test at the busy hour during the trial.
How do I tell whether AT&T at my address is fiber or Internet Air?
The two products carry the same logo and very different speeds. AT&T Fiber is a symmetrical line with plans from $35 a month up to 5 Gig and no data caps.[2] Internet Air is a 5G gateway sold where fiber has not been built.
Two ways to find out. Run the address check on AT&T's site: if the plans shown carry the word Fiber, you have it; if the only plan is Internet Air, you do not. Or ask a neighbor what upload speed they get. Fiber uploads as fast as it downloads; cable and 5G do not.
What should I ask before I sign up?
- What does the bill become after the promotion? AT&T's $50 for 300 Mbps needs autopay and paperless billing; Nextlink's $30 rises to $50 in month 13.[2][7]
- Is there a term agreement? AT&T, Xfinity, T-Mobile, Verizon and Google Fiber say no annual contract; Spectrum's standard terms were not on the page we could reach.[5]
- Is data unlimited? AT&T, Xfinity, Google Fiber, T-Mobile and Nextlink say yes.[2][6][10][3][7]
- Is the gateway included, and is there a fee to use your own router?
- How soon is the install, and does fiber need a new drop to the house?
- Does the provider send notice before the price changes at renewal?
Frequently asked questions
Who has the best internet in Texas?
AT&T Fiber for most homes, because AT&T reaches the most Texas addresses and its fiber beats cable and 5G on speed and consistency. Where AT&T only offers Internet Air, Xfinity in Houston or Spectrum elsewhere is the better daily driver.
What is the fastest internet in Texas?
AT&T Fiber's 5 Gig tier is the fastest widely sold residential plan in the state.[2] Google Fiber in Austin and San Antonio offers 1 Gig at $70 and faster tiers above it.[10]
Is Xfinity available in Texas?
Yes, mostly in the Houston area, where it is the dominant cable provider. Dallas, Fort Worth, San Antonio, Austin and El Paso are Spectrum markets.[1]
What is the cheapest internet in Texas?
Nextlink's $30 fiber plan in its areas and Spectrum Internet Assist at $25 for qualifying households are the lowest published rates we found.[7][5] AT&T Fiber plans start at $35, and Verizon 5G Home is $35 with a Verizon phone plan.[2][4]
