FCC-reported internet coverage levels by technology for ZIP 78220
FCC-reported coverage levels by technology near ZIP 78220. Levels count the providers reporting each technology in the sampled area; confirm service at your address.

The reported provider sample near 78220 includes Spectrum with a Cable label and AT&T Internet with a Fiber label. Enter the complete service address, including an apartment or unit, to learn which connection can actually be ordered. A provider appearing in this ZIP summary does not establish service to your building.

Arrange the connection around the property

Before booking installation, find out who controls access to the cable or fiber entry point. A renter may need a property manager to unlock a utility room; a homeowner should ask where the technician expects to place equipment. Get the appointment window and access requirements together so a missing key does not interrupt the work.

The extracted FCC coverage bands describe any broadband as reaching nearly all of the area, cable most, and fiber part. These are area summaries from FCC broadband reporting, rather than a prediction of your connection's performance. Use the internet speed planning guide to separate household workload from the availability question.

Carver's services have moved during renovation

Carver Branch Library's building at 3350 East Commerce Street, San Antonio 78220, is closed for renovation. The library specifically lists outdoor Wi-Fi, the book drop, meeting rooms and computers as unavailable at that original site.

Its current branch notice directs visitors to interim services at Denver Heights Community Center, 300 Porter Street, San Antonio 78210. That is a different ZIP and a different destination. The interim location offers holds pickup and returns, a browsing collection, account assistance, indoor Wi-Fi and computer access. Curbside help is available on request.

For someone moving in, this distinction can save a wasted trip to return a book or finish an online form. Check the interim schedule on the branch page, and ask staff about any task that needs a particular program, scanner or private space; the listed computer access does not establish those additional facilities.

Questions about getting connected in 78220

Should I request cable or fiber first?

Check both against your address. Then compare the actual connection, equipment arrangement and installation requirements offered there. The two technology labels above describe reported service, not two guaranteed choices for every resident.

Can I use Carver's outdoor Wi-Fi while the building is closed?

The closure notice says it is unavailable at East Commerce Street. For the listed interim indoor Wi-Fi and computers, use the Denver Heights address and its current service hours.

What should I keep from my order confirmation?

Save the service address, selected plan, appointment window and equipment instructions somewhere you can open without home internet. Keep a contact method available if access arrangements change.

How We Rank Providers & Where the Data Comes From

Provider names and sampled advertised technology and speed evidence on this page come from the FCC National Broadband Map and the FCC Broadband Data Collection (June 2025), sampled at H3 grid-cell granularity. ZIP results are shortlist evidence, not address-level serviceability. National catalog plans are excluded until market eligibility is proven. Confirm service, the current offer, and installation terms at the exact address. See our full ranking methodology.
