Cox Internet in Texas: Plans, Pricing, and Coverage for 2026

Cox Communications is one of the largest cable internet providers in the United States, but its Texas coverage is surprisingly limited. Unlike Xfinity and Spectrum which serve millions of Texas addresses, Cox operates in only a handful of Texas markets — primarily parts of West Texas and the northern panhandle region. Major metros like Houston, Dallas, San Antonio, Austin, and El Paso are not in Cox's Texas service area.

For the Texas communities where Cox is available, it functions as the primary cable internet provider, often competing only with AT&T (DSL or limited fiber) and fixed-wireless options. Cox's product is solid cable internet with speeds up to 2 Gbps on the top tier, but it comes with data caps and contract requirements that can be frustrating.

If you live in a Cox service area in Texas, this guide will help you understand the plans, pricing, and limitations. If you are moving to Texas and currently have Cox, be aware that you will likely need to switch providers depending on your destination city.

All plans except Gigablast 2.0 are subject to Cox's 1.25 TB monthly data cap. Exceeding the cap costs $10 per 50 GB block, up to $100/month. You can add unlimited data for $50/month. Cox plans generally require a 12-month agreement for the promotional pricing shown.

Cox's Texas footprint is limited to select markets primarily in the western and northern parts of the state. Major Cox service areas in Texas include portions of the Lubbock metro area, parts of the Abilene region, sections around Wichita Falls, and scattered coverage in smaller West Texas and Panhandle communities.

Notably, Cox does not serve any of the four largest Texas metros: Houston, Dallas-Fort Worth, San Antonio, or Austin. It also does not serve El Paso, Corpus Christi, or the Rio Grande Valley. This means the vast majority of Texans do not have Cox as an option.

For residents in Cox's Texas service areas, the competitive landscape is often limited. AT&T may offer DSL or IPBB (rarely fiber) as the primary alternative, and T-Mobile 5G Home Internet provides a wireless option where available. The lack of strong competition in these markets is reflected in Cox's pricing, which tends to be higher per-megabit than what consumers in larger Texas metros pay for comparable speeds from Spectrum or Xfinity.

For Texas residents in Cox's limited service areas, Cox is often the best wired option simply because alternatives are sparse. If Cox is the dominant cable provider in your community and AT&T only offers DSL, then Cox's cable speeds will be significantly better for everyday internet use.

However, Cox's pricing is relatively high compared to the state's larger cable providers. The $50/month entry point for 100 Mbps is more expensive than Spectrum at $30/month for 300 Mbps in the markets Spectrum serves. The 1.25 TB data cap on most plans adds another cost concern for heavy-use households.

Before committing to Cox, check T-Mobile 5G Home Internet availability. At $50/month with no data caps and typical speeds of 72-245 Mbps, T-Mobile can be a competitive alternative to Cox's lower tiers. For the best Cox value, the Gigablast 2.0 plan at $150/month includes unlimited data and 2 Gbps speeds — but this is a premium price that only makes sense for heavy-use households.
