Frontier vs AT&T Internet Service Review

Each company sells two kinds of home internet, and your address decides which of them, if any, you can get. For plans by address, see our AT&T and Frontier provider pages.

AT&T lists Internet Air from $55 a month, with AutoPay and paperless billing required, and says about 25% of the customers in its speed tests got less than the typical range. If one company offers fiber at your address and the other offers only a non-fiber service, compare upload speeds first: both fiber services advertise uploads equal to downloads, and AT&T says equal speeds help with video calls, cloud backups and sharing large files.

Fiber against fiber: the terms side by side

Where both companies offer fiber, these are the terms each published when we checked on October 20, 2026, with no address entered. Prices exclude taxes and fees and vary by address.

Two details move the AT&T price. Its $10 AutoPay discount applies when you pay from a bank account or the AT&T Points Plus card; it drops to $5 with a debit card and to nothing with any other credit card, which adds $120 or $240 over two years. AT&T also says its discounts can take two or three bills to start, so early bills can be higher. On Frontier's side, the guarantee covers only the base monthly rate, not installation, extra equipment charges, discounts or promotions. Frontier's offer does not mention Auto Pay. Product information coded into its Fiber 1 Gig plan page, but not shown to shoppers, describes $64.99 as a price with Auto Pay for 12 months, which conflicts with the five-year guarantee the offer shows. Before you order, ask Frontier to confirm in writing whether $64.99 requires Auto Pay, what the plan costs without it, and that $64.99 is the rate the five-year guarantee covers. For both providers on one page, see our AT&T vs. Frontier comparison.

What two years of gigabit fiber could cost

A long price guarantee pays off after the first year, so this example prices 24 months at the gigabit tier. It assumes:

• an address where both companies sell gigabit fiber, and a new customer ordering internet only;
• AT&T AutoPay and paperless billing from a bank account, with both AT&T discounts starting on the first bill;
• an AT&T second-year rate of $80. AT&T does not print this rate, so $80 is our inference: the $90 price AT&T showed before discounts, minus the $10 AutoPay discount;
• Frontier's listed $64.99 applying at the address for all 24 months, with Auto Pay if Frontier requires it;
• no phone-plan discounts, and no taxes or fees.

In this example Frontier costs $240.24 to $339.24 less over two years, and most of the gap opens in year two, after AT&T's 12-month discount ends. Three things can change that:

• A phone plan. AT&T lists a $20-a-month discount on 1 GIG fiber for customers with an eligible AT&T unlimited phone plan, for as long as they keep it; that lowers the AT&T total here to $1,320 to $1,419. Frontier advertises $15 a month off eligible Frontier Fiber plans for customers with a qualifying Verizon mobile plan, but the page we checked did not clearly say how long that discount lasts. If your household would use either, price both bundles.
• AT&T's rate after 12 months. AT&T says only that its prevailing rate applies, so ask for that figure before you order.
• Frontier's Auto Pay terms. If $64.99 needs Auto Pay and you would not use it, or if $64.99 is not the rate the five-year guarantee covers, the Frontier total rises. Confirm both before you order.

Four checks before you order

1. See who reports service at the address. The FCC's National Broadband Map shows which providers report offering service at each home, with the technology and the maximum advertised download and upload speeds. That is provider-reported data, and you can challenge it, for example when a provider denies a request for service or fails to schedule an installation within 10 business days. Only each company's own address check and a written order confirm what you can buy.
2. Ask which connection each company would install. AT&T Fiber or Internet Air; Frontier Fiber or Frontier's non-fiber service. Get the plan name and its download and upload speeds in writing.
3. Read the broadband label for that plan. The FCC requires providers to have a broadband label for each plan and to make it available where they sell the plan, disclosing the price, any introductory rate, the data allowance and speeds. Compare the price after any introductory period ends.
4. Price the whole bill. Add installation, Wi-Fi add-ons and taxes. AT&T adds a monthly State Cost Recovery charge in Nevada, Ohio and Texas. With Frontier, ask whether your plan carries the 12-month commitment and prorated early termination fee its FAQ describes.

Questions readers ask

Is Frontier Fiber or AT&T Fiber better?

Neither is better everywhere. Both advertise equal upload and download speeds and no data caps. In our October 20, 2026 check, Frontier offered a five-year price guarantee on Fiber 1 Gig and free installation on its 1 Gig, 2 Gig and 5 Gig plans. AT&T's fiber pages listed a 12-month new-customer discount rather than a price guarantee, a 300 Mbps plan at $50 a month with AutoPay, and a fiber discount for eligible AT&T phone customers. Start with whichever one serves your address.

Are Frontier and AT&T the same company?

No. AT&T lists Frontier among the other fiber providers to compare it with, and Frontier says it has joined Verizon. Frontier still sells its plans under the Frontier name.

Does AT&T still offer DSL?

No. AT&T says it no longer offers DSL service. Where AT&T Fiber has not been built, AT&T may offer Internet Air, its 5G home internet service, which AT&T says delivers typical download speeds of 90 to 300 Mbps and uploads of 8 to 30 Mbps.

How long do AT&T and Frontier prices last?

Frontier guarantees the base monthly rate for four years on Fiber 500 and five years on Fiber 1 Gig, 2 Gig and 5 Gig, but not installation, extra equipment charges, discounts or promotions. AT&T's new-customer fiber discount on its 500 Mbps, 1 GIG and 5 GIG plans lasts 12 months, after which AT&T's prevailing rate for the plan applies.
