Check Carriers at Your AddressAT&T Business sells fiber in its local footprint, dedicated internet nationally, and fixed wireless (Internet Air for Business). It's a reasonable choice for many sites, but rarely the only one. Here's what else is out there and how to compare it.
The right alternative depends on what's built to your address. These are the providers we compare most often:
| Provider | What they sell | Best for |
|---|---|---|
| Comcast Business | Cable broadband, Ethernet and dedicated internet | Wide cable coverage; Ethernet where built |
| Verizon Business | Fios fiber (Northeast and Mid-Atlantic), dedicated internet, 5G business internet | Fiber where Fios is built; DIA nationwide |
| Spectrum Business / Spectrum Enterprise | Cable broadband; fiber, Ethernet and DIA via Spectrum Enterprise | Sites in the Spectrum footprint |
| Lumen | Fiber-based dedicated internet, Ethernet, wavelengths | Multi-site and enterprise DIA |
| Cox Business | Cable broadband and fiber | Businesses in Cox markets |
| Zayo | Fiber, dedicated internet, wavelengths | Bandwidth-heavy sites and data center links |
| Regional fiber providers | Local fiber and dedicated internet | Buildings a regional network already reaches |
| 5G fixed wireless (T-Mobile, Verizon, AT&T) | Wireless business internet | Fast installs and backup circuits |
| Starlink Business | Satellite internet | Remote sites with no wired option |
Availability is building-specific. Two offices on the same street can have different carriers on-net, so a quote list should start from your exact address.
Shared fiber with fast, often symmetrical speeds. Good for most small offices. See business fiber.
Bandwidth reserved for you, symmetrical speeds and an SLA. See DIA pricing.
Installs in days, not months. Good as a primary where fiber isn't built, or as backup. See fixed wireless.
It depends on your address. For most offices the strongest alternatives are whichever fiber or dedicated internet providers are already on-net in your building. Discover Communications checks that for free and returns side-by-side quotes within 48 hours.
