Lumen is hungry right now. They sold off the Mass Markets fiber business in February 2026 and shed $4.8 billion in debt. The enterprise division is what's left, and it's the part of the company that pays the bills. That changes how their reps behave. They will negotiate harder than AT&T or Verizon on price. They will also push managed services hard, because that's where the margin is. Their support reputation is mixed. Billing disputes after disconnects are a known pattern, and the subscriber agreement gives you six months to dispute an invoice charge. Miss that window and the charge stands.
Lumen used to be CenturyLink, before that Qwest, before that several regional Bells. The footprint is huge. The price-to-speed ratio is mid-pack. Most overpayment we see on Lumen bills comes from old enterprise contracts that never got reviewed when the cheaper fiber overbuilders showed up.
This guide walks through what Lumen Business actually charges in 2026 and how to tell if your contract is competitive.
Lumen's enterprise pivot in 2026
Lumen Business remains part of Lumen Technologies, Inc. (NYSE: LUMN), and the most material 2023-2026 change affecting its broadband perimeter was the February 2, 2026 close of AT&T's acquisition of substantially all of Lumen's Mass Markets fiber business, which Lumen said sharpened its enterprise focus while leaving enterprise backbone assets with Lumen. Lumen's public network materials describe one of North America's largest enterprise fiber footprints, including about 25,000 route miles of next-generation dark fiber, about 163,000 on-net buildings, 2,200-plus on-net third-party data centers, and 35-plus major metros on RapidRoutes, with documented business service nodes in Atlanta, Chicago, Dallas, Denver, and Phoenix.
On February 2, 2026, AT&T completed the $5.75 billion purchase of Lumen's Mass Markets fiber business, and Lumen said the closing reduced debt by more than $4.8 billion and advanced its enterprise-only strategy. On the billing side, CenturyLink and Lumen complaint channels show a recurring pattern of billing disputes after service issues or disconnects; CenturyLink's BBB page includes 2026 complaints over balances that remained after disconnects and unreturned-equipment charges despite proof of return, and the enterprise subscriber agreement also imposes a six-month deadline to dispute invoice charges.
Lumen does not publish a stable monthly dollar figure for Dedicated Internet Access on its public DIA page. The listed rates exist for eligible on-net locations on 36-month terms, but the actual monthly price only appears once you enter the marketplace purchase flow with a real address. That is the single biggest reason Lumen quotes feel inconsistent across two offices on the same metro.
What Lumen sells
Three main product lines.
- Lumen Fiber+ Internet. Symmetrical fiber, available in select markets. 200 Mbps to 8 Gbps.
- Dedicated Internet Access. Sold to mid-market and enterprise. Symmetrical with a real SLA. Higher cost.
- MPLS, SD-WAN, and managed services. Where most of the enterprise bill goes.
Lumen is one of the bigger sellers of MPLS, which used to be the default WAN for multi-site businesses. The pivot to SD-WAN over the last five years has cut typical WAN costs by 50 to 84 percent, and most Lumen MPLS customers can save real money by switching at their next renewal.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Lumen and peers, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes. Shown as a metro-tier band where city-level data is thin.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $800/mo | n = 7 |
| 500 Mbps | $840 – $1,160/mo | n = 5 |
| 1 Gbps | $1,050 – $1,455/mo | n = 6 |
| 10 Gbps | $1,330 – $2,660/mo | n = 7 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor Lumen Fiber+ Internet (broadband, not DIA), a 1 Gbps fiber line should land between $200 and $300 a month in major metros. The product is fine, but the price is rarely the headline number on the new-customer rate card.
The MPLS to SD-WAN math
If your business has more than two locations, this is the single biggest savings opportunity on a Lumen bill.
- Average MPLS line in 2026: $1,200 to $2,500 a month per site.
- Average SD-WAN replacement: $200 to $500 a month per site, plus a one-time appliance cost of $500 to $2,000.
- Industry adoption of SD-WAN hit 75 percent of mid-market businesses in 2026. The few still on pure MPLS are the ones overpaying.
We have a longer post on this: The SD-WAN vs MPLS Cost Gap Got Wider in 2026.
The four side charges to flag on Lumen bills
- Carrier Cost Recovery Fee. Looks like a tax, is not. Lumen margin. Often 6 to 10 percent of the base rate.
- Federal Universal Service Fund (FUSF) fee. Real federal tax, but only on the interstate portion. We see Lumen apply it to broadband-only bills where it should not apply at all.
- Equipment rental. $20 to $40 a month for the gateway or managed router.
- Static IP and BGP fees. Add up fast on enterprise bills.
How Lumen pricing changes at renewal
Lumen Business contracts often run 36 or 60 months. The auto-renewal rate is typically 15 to 25 percent above the term rate.
- Lumen retention is more conservative than the cable carriers. The discount they will offer is usually 10 to 20 percent off the renewal rate.
- A competing quote from a fiber overbuilder, AT&T, or a fixed wireless option gives you the strongest leverage.
- The window that matters is 90 to 120 days before contract end. Lumen contracts often have notice clauses that lock you in if you do not give written notice.
What to do this week
- Pull your most recent Lumen Business invoice. Find the contract end date and the notice clause.
- Add up the Cost Recovery, FUSF, and rental fees. Subtract them from the total to find your true base rate.
- If you have multiple sites on MPLS, get one SD-WAN quote. The number alone is often enough to start the conversation.

Frequently asked questions
Is Lumen Business the same as CenturyLink?
Yes. CenturyLink rebranded to Lumen Technologies in 2020. Some legacy contracts and billing portals still show CenturyLink. The enterprise division is now called Lumen Business. The Mass Markets consumer fiber business was sold to AT&T in February 2026, so the residential and small business fiber side is no longer Lumen's.
How long is Lumen Business's contract dispute window?
Six months from the invoice date. The enterprise subscriber agreement requires you to dispute charges within that window. After six months, the charge is considered accepted. This is shorter than most carriers and is a real risk if you don't review bills monthly. Set a calendar reminder to audit invoices quarterly at minimum.
Does Lumen Business auto-renew contracts?
Yes. Service orders auto-renew month-to-month after the initial term unless you give written notice. The notice window is 30 to 60 days depending on the specific service order. Pricing stays at the original rate, which is almost always above current market by year three. Calendar the cancellation window 90 days before contract end.
How negotiable is Lumen Business pricing?
More negotiable than AT&T or Verizon in 2026. Lumen is focused on enterprise revenue after the Mass Markets divestiture and has been hungry for deals. A real competitive quote from a regional fiber provider will move the price 20 to 30 percent below the published rate card. Without a competing quote, expect single-digit discounts.
What is Lumen Business's ETF?
Standard 100 percent of the remaining contract value. There is no diminishing ETF schedule for typical SMB contracts. Large enterprise accounts can sometimes negotiate a stepped ETF, 100 percent year one, 75 percent year two, 50 percent year three. The portability clause is a better workaround. It lets you move spend to a new site or service without triggering the fee.
Is Lumen Business fiber actually available at my building?
Lumen claims about 163,000 on-net buildings across North America, concentrated in 35-plus major metros. On-net pricing is competitive. Off-net quotes include local loop build costs and a markup, which makes them uncompetitive against regional fiber. Ask the rep for an on-net check before accepting any quote. If you're off-net, get two other quotes before signing.
