AT&T sells business internet off two very different price lists. Business Fiber has published prices, month to month terms, and behaves like a modern subscription. Dedicated internet is classic enterprise telecom: quoted per address, contracted per term, and priced by what the fiber map says about your building. Knowing which list your address qualifies for is most of understanding an AT&T quote. For how AT&T compares to the other carriers, see our Best Business Internet Providers ranking.
What you will actually pay
Published Business Fiber tiers run from roughly $70 per month at the entry speeds to about $400 for multi gig, with symmetrical upload throughout, equipment included, and typically no annual contract. Discounts for autopay and for bundling wireless are standard and worth taking. Where fiber is available, this list is refreshingly literal: the advertised number, minus routine discounts, is close to what lands on the bill, and the absence of a term means the price is not hiding behind a promo cliff the way cable pricing does.
AT&T Dedicated Internet is the other list: quote based by address, bandwidth, and term, with an SLA and support obligations broadband does not carry. On net buildings, where AT&T fiber already terminates, price dramatically better than buildings needing construction. If your building is not on net, the quote reflects the build, or a longer term absorbs it.
What moves the price
- Serviceability. Whether your address has AT&T fiber, and at what class, decides everything else. This is a lookup, not a negotiation.
- Speed tier fit. Fiber's symmetrical upload means the entry tiers genuinely serve most offices. Buy for your actual usage; upgrading later is trivial precisely because there is no term.
- Broadband versus dedicated. The same bandwidth costs several times more as a dedicated circuit. What you are buying is the SLA, the guaranteed capacity, and the support path. If an outage stops revenue, that is the comparison to price.
- Term, on the dedicated side. Longer terms pull monthly rates down and absorb construction. Match the term to how long you will occupy the building.
Contract factors to watch
- Bundling discounts. Wireless and fiber together earn ongoing discounts. Genuine value, but price the internet standalone first so the bundle competes on merit.
- Install timelines, not just fees. On the dedicated side, construction can take months. If you have a lease start date, sequence the order backward from it and get the interval in writing.
- Renewal on dedicated circuits. Dedicated contracts that lapse tend to renew at unfavorable rates. Calendar term end; a market re quote at renewal is routine and usually saves money.
- The two lists are separate negotiations. A great Business Fiber price at one site says nothing about the dedicated quote at another. Multi site portfolios deserve a carrier level conversation, not per site orders.
The honest summary: where AT&T fiber reaches, its published pricing is among the most honest in the category; where it does not, you are in quote territory where the address decides. We check every carrier at your address at once, broadband and dedicated both, free, and we are paid the same standard referral commission whichever provider you choose.
