Best & Worst ISP Customer Service in Texas — Ranked (2026)

**American Customer Satisfaction Index (ACSI):** The ACSI surveys tens of thousands of U.S. consumers annually and publishes ISP-specific satisfaction scores on a 0-100 scale. The 2025-2026 ACSI Telecommunications Report covers internet service providers individually. We use ACSI as our primary weighting factor because it captures the broadest consumer sentiment.

**JD Power U.S. Residential Internet Service Provider Satisfaction Study:** JD Power evaluates ISPs across six factors — performance and reliability, cost, communication, billing, customer service interactions, and account management. Their South Region scores are most relevant to Texas consumers. We weight JD Power as our secondary factor.

**Better Business Bureau (BBB) complaint volume:** We pulled complaint counts for each ISP's Texas-serving entities from the BBB database, normalized by estimated subscriber count in the state. High complaint density (complaints per 100,000 subscribers) indicates systemic customer service failures. We use BBB data as a penalty factor — providers with outsized complaint volumes are penalized in our final ranking.

**Final score formula:** 50% ACSI score + 30% JD Power index (normalized to 100) + 20% BBB complaint penalty. Providers serving fewer than 50,000 Texas subscribers are noted but not formally ranked due to limited data reliability.

**1. Google Fiber — ACSI 78, JD Power "Among the Best"**

Google Fiber consistently earns the highest customer satisfaction scores of any ISP operating in Texas. Available in Austin, San Antonio, and expanding in the DFW metro area, Google Fiber's advantage is simplicity: one plan (1 Gig or 2 Gig), transparent pricing with no hidden fees, no contracts, and no data caps. Their support team is US-based, average hold times are under 3 minutes, and first-call resolution rates exceed 85% according to JD Power survey data. BBB complaints against Google Fiber in Texas are minimal relative to their subscriber base.

**2. T-Mobile Home Internet — ACSI 74, JD Power "Better Than Most"**

T-Mobile's 5G Home Internet has disrupted the Texas broadband market not just on price but on customer service. Their support operates 24/7 with a "Team of Experts" model that assigns customers to a dedicated regional support team rather than routing calls through generic call centers. Average hold times run 2-5 minutes. T-Mobile's BBB complaint volume in Texas is low, partly because their no-contract model eliminates billing disputes tied to early termination fees. The main service complaint is speed variability, not support quality.

**3. AT&T Fiber — ACSI 73, JD Power "About Average"**

AT&T's customer service reputation is split. AT&T Fiber customers report significantly higher satisfaction than AT&T DSL or legacy U-verse customers. Fiber subscribers praise the reliable speeds and straightforward billing, but installation scheduling and technician availability remain pain points in fast-growing Texas metros like Austin and DFW. AT&T's BBB complaint volume is moderate — driven largely by DSL service issues, billing disputes, and promotional price expiration confusion rather than fiber-specific problems.

**4. Frontier Fiber — ACSI 68, JD Power "About Average"**

Frontier's customer service has improved substantially since its fiber network buildout, but the company still carries reputational baggage from its legacy DSL era and its 2020 bankruptcy. Texas Frontier Fiber customers in markets like Dallas and Houston report better experiences than the national average. Hold times average 8-12 minutes, and first-call resolution has improved to approximately 70%. BBB complaints have decreased year-over-year but remain above average per subscriber.

**8. Xfinity (Comcast) — ACSI 62, JD Power "Below Average"**

Xfinity consistently ranks near the bottom of every major customer satisfaction survey in the United States, and Texas is no exception. The most common complaints from Texas Xfinity customers include: unexpected bill increases after promotional periods expire, difficulty reaching a human agent (average hold times of 20-35 minutes reported by consumers), aggressive upselling during support calls, data cap enforcement and overage charges ($30/50GB over the 1.2TB cap), and technician appointment windows that are missed or rescheduled. Xfinity's BBB complaint density in Texas is among the highest of any ISP, with billing and service cancellation disputes comprising the majority.

**7. Cox Communications — ACSI 63, JD Power "Below Average"**

Cox serves parts of the Texas market and scores only marginally better than Xfinity. Common Texas complaints center on pricing opacity — promotional rates that jump 40-60% after 12 months — and slow response times for service outages. Cox's BBB profile in Texas shows elevated complaint volumes around billing practices and contract terms. Their live chat and phone support average 15-25 minute wait times during peak hours.

**6. Spectrum (Charter) — ACSI 65, JD Power "About Average"**

Spectrum falls in the lower-middle tier for customer service. Their no-contract model and included modem are positives, but Texas customers frequently cite slow support response times (15-20 minutes average hold), difficulty getting credits for service outages, and a perception that speeds do not match advertised rates during peak evening hours. Spectrum's BBB complaint volume is moderate — lower than Xfinity and Cox but higher than AT&T Fiber or Google Fiber.

**5. HughesNet / Viasat — ACSI 60-64, JD Power "The Rest"**

Satellite ISPs occupy a unique space. Their customer service scores are low, but much of the dissatisfaction is driven by the inherent limitations of satellite technology (high latency, data caps, weather sensitivity) rather than support quality per se. Texas consumers in rural areas who rely on HughesNet or Viasat report frustration with data cap enforcement and the perception that alternatives like Starlink are not being fairly compared by sales agents.

**Call at off-peak times.** Support lines for Xfinity, Spectrum, and Cox are least busy Tuesday through Thursday between 9-11 AM CST. Avoid calling Monday mornings (post-weekend outage backlog) and Friday afternoons.

**Use social media for escalation.** Every major ISP monitors Twitter/X and Facebook for public complaints. Posting a specific, factual complaint (include your city, the issue, and how long it has been unresolved) on @XfinitySupport, @Ask_Spectrum, or @TMobileHelp often gets faster response than phone support. Companies prioritize public-facing complaints to protect brand reputation.

**File a Texas PUC complaint.** The Public Utility Commission of Texas (PUC) accepts complaints about internet service providers. While the PUC's direct regulatory authority over broadband is limited, filing a formal complaint creates a record and often triggers an escalated response from the ISP. File online at puc.texas.gov.

**File an FCC complaint.** The FCC's Consumer Complaint Center (consumercomplaints.fcc.gov) is the most effective escalation tool available to consumers. ISPs are required to respond to FCC complaints within 30 days. Many Texas consumers report that filing an FCC complaint resulted in bill credits, waived fees, or resolution of long-standing issues within 1-2 weeks.

**Know your cancellation leverage.** If you have a competing provider available at your address (check the FCC broadband map), mention the specific alternative when negotiating with your current ISP. Retention departments have more authority to offer discounts and credits than frontline agents. In Texas markets where Google Fiber or T-Mobile 5G compete with cable incumbents, mentioning a switch often triggers a retention offer of 20-30% off your current rate.

**Document everything.** Keep records of every support interaction — date, time, agent name or ID, and what was promised. Texas follows a one-party consent law for call recording, meaning you can legally record your own support calls without the agent's permission. This documentation is invaluable if you need to escalate to the PUC, FCC, or BBB.
