Internet Providers in Houston, TX 2026
Houston is the largest US city by area — and ISP availability varies dramatically by neighborhood. Xfinity cable covers the widest area but comes with a 1.2 TB data cap. AT&T Fiber is available across most of the metro at no data cap from $55/mo. T-Mobile 5G Home at $50/mo is a reliable backup. Most Houston addresses have two or three real choices.

Houston's data cap problem. Xfinity enforces a 1.2 TB monthly data cap on most plans in Houston. A household of 4 streaming in 4K, gaming, and working from home can hit 1.2 TB in 3–4 weeks. Overage fees are $10 per extra 50 GB block, up to $30/mo. Adding unlimited data costs $30/mo extra — which means the real cost of Xfinity is often $20–40/mo higher than advertised. AT&T Fiber has no data cap at any tier.

Houston ISP Breakdown
AT&T Fiber — Best overall
$55/mo
300 Mbps – 5 Gbps symmetric
Pure fiber to the home. Symmetric speeds mean 300 Mbps upload on the 300 Mbps plan — important for WFH video calls, uploading large files, and gaming. AT&T's fiber network in Houston is extensive, covering most inner-loop neighborhoods and large portions of the suburbs.
- No data cap at any tier
- Symmetric upload = download speeds
- Price does not spike after 12 months
- No equipment rental fee
Not available at every address — check att.com/internet
Xfinity — Widest coverage
$35/mo
150 Mbps – 2 Gbps download
Xfinity (Comcast) covers more Houston addresses than any other provider, including areas where AT&T Fiber hasn't yet arrived. Fast download speeds — but the 1.2 TB data cap is a real-world problem for heavy users. Always factor in the true monthly cost including equipment rental ($15–20/mo) and potential unlimited add-on ($30/mo).
- Broadest coverage in the metro
- Fast download speeds (up to 2 Gbps)
- Often the only wired option in outlying areas
1.2 TB data cap; equipment rental $15–20/mo; promo rates expire
T-Mobile 5G Home
$50/mo
100 – 400 Mbps (location varies)
No installation, no contract, no data cap. Plug in the gateway and it works. Speeds depend on your proximity to a 5G tower — most Houston neighborhoods are well covered, but speeds during evening peak hours can vary. Use T-Mobile's 15-day trial to test at your address.
- Flat $50/mo — no rate changes
- No data cap, no contract
- Self-install in 15 minutes
- 15-day money-back trial
Peak-hour speeds can drop; upload speeds lower than fiber
Xfinity: The real cost
$35 → $95+
Advertised vs. what you'll actually pay
The $35 promotional rate applies to new customers on the starter plan for 12 months. After that, expect $55–70/mo for the same speed. Add a modem rental ($15–20/mo), and unlimited data ($30/mo for heavy users), and a typical Xfinity bill in Houston runs $85–120/mo — vs. AT&T Fiber at $55–80/mo with no extras needed.
- Use this breakdown when comparing offers
- Ask about current promotions and rate-lock options
Always ask: "What's the rate after the promotional period?"

Houston's Data Cap Problem — The Real Numbers
Xfinity's 1.2 TB cap affects real Houston households more than people expect. Here's what a typical 4-person household actually uses in a month:
- Streaming: 2 TVs streaming 4K Netflix = ~300 GB/week = 1.2 TB/month on streaming alone
- Gaming: Modern game downloads run 50–130 GB each; patches can be 10–30 GB
- Work from home: Full-day video calls on Zoom/Teams = ~1.5–2 GB/hour = 15–20 GB/day
- Smart home + background: Security cameras, cloud backup, iOS updates, app syncing = 50–100 GB/mo
Bottom line: A household with 2 remote workers and 2 4K streaming TVs will routinely hit 1.2 TB well before month-end. Xfinity's unlimited add-on ($30/mo) plus equipment rental ($15–20/mo) adds $45–50/mo to the base rate — making AT&T Fiber 300 Mbps at $55/mo the better deal for most Houston families.
Which Houston ISP Is Right for You?
Best overall
AT&T Fiber
No cap, symmetric speeds, flat rate. The right choice for most Houston households if it's available at your address.
Lowest monthly bill
T-Mobile 5G Home
$50/mo flat, no contract, no equipment fee, no data cap. Best if AT&T Fiber isn't available at your address.
Gaming
AT&T Fiber
Fiber's symmetric speeds and low latency win for online gaming. Xfinity's data cap is a real risk for heavy gamers downloading large games.
Working from home
AT&T Fiber 300+
Symmetric upload speeds matter for video calls. AT&T 300 Mbps gives 300 Mbps upload — vs. Xfinity's ~20–30 Mbps upload on comparable plans.
4K streaming household
AT&T Fiber (avoid Xfinity cap)
A household with 2+ 4K streams running daily will often exceed Xfinity's 1.2 TB cap. AT&T Fiber has no cap at any speed tier.
Light internet use
T-Mobile 5G Home or Xfinity
For browsing, email, and occasional video streaming, any provider works. T-Mobile at $50/mo or Xfinity promo rates are the most affordable starting points.
