Mobile is a duopoly market with a long tail of alternatives that most buyers never get quoted. AT&T Business Fiber and Spectrum Business win the default purchase, but the metro sits on top of meaningful long-haul fiber thanks to the Mobile-to-Montgomery build and existing routes along I-10. That backhaul matters for DIA pricing. The Port of Mobile, the Brookley aerospace campus, and a downtown stacked with pre-1950 building stock create a split market: modern on-net fiber in some blocks, off-net build quotes two streets over. Quote spreads of 40 percent on the same speed are normal here, not an outlier.
Mobile is mostly an AT&T and Spectrum market. AT&T Business Fiber covers a large share of commercial blocks. Spectrum Business has the dominant cable footprint across the metro. T-Mobile fixed wireless is widely available with strong coverage across the Gulf Coast.
The pricing problem in Mobile is the assumption that small markets have small price gaps. The spread between the cheapest and most expensive quote in this metro is often 40 percent or more.
Mobile's commercial waterfront
Mobile's commercial demand sits in three places. Downtown Mobile holds the legal, financial, and government corridor along Government Street and the Mobile River waterfront. Lower Dauphin, the historic commercial spine running through downtown, anchors a deep cluster of restaurants, retail, and small-office tenancy. The Mobile Aeroplex at Brookley, the city-owned former Air Force base that has been redeveloped into an aerospace and industrial campus, is the metro's largest concentration of advanced-manufacturing and aerospace tenancy. The Airbus U.S. Manufacturing Facility at Brookley and Infirmary Health, the largest non-government health system in Alabama, are two of the largest commercial accounts in the metro and drive heavy enterprise telecom demand.
In 2024, Uniti announced a new long-haul fiber build of more than 200 route miles between Mobile and Montgomery for a hyperscale customer, adding meaningful regional fiber capacity through south Alabama. One pricing wrinkle: Downtown Mobile properties inside the 75-block BID fund enhanced services through annual assessments, with a sliding scale tied to property value and exemptions or reductions for some owner-occupied residential and nonprofit properties.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Mobile dedicated internet, 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 – $1,060/mo | n = 6 |
| 500 Mbps | $955 – $1,660/mo | n = 6 |
| 1 Gbps | $1,195 – $2,000/mo | n = 7 |
| 10 Gbps | $1,560 – $6,250/mo | n = 6 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor AT&T Business Fiber at 1 Gbps, expect $150 to $230 a month for a single office. For Spectrum coax at 600 Mbps, the fair price is $150 to $230 a month.
Carriers worth quoting in Mobile
Five carriers cover most addresses in the metro.
- AT&T Business Fiber. Strong commercial fiber footprint across the metro.
- Spectrum Business. Coax everywhere, fiber in select buildings.
- Crown Castle Fiber. Common in commercial buildings downtown.
- T-Mobile Business Internet. $85 a month for 200 to 300 Mbps. Useful benchmark.
- Verizon 5G Business Internet. $99 a month at 400 Mbps.
If you have not had three of these on a quote sheet, you have not run a real comparison.

Carriers worth a quote here
- AT&T Business
AT&T is the ILEC and the most-quoted carrier in the metro. Fiber coverage is strong across downtown, Midtown, west Mobile along Airport Boulevard, and most of the Brookley campus. They are negotiable at end of quarter but rarely lead with their best price.
- Spectrum Business
Spectrum has the dominant cable footprint and competes hard against AT&T fiber on broadband pricing. Their DIA product is available in most commercial buildings but priced 15 to 25 percent above AT&T fiber for equivalent dedicated speeds.
- C Spire Fiber
C Spire has been building business fiber across the Mobile metro and is the most credible third option for SMBs. Pricing is aggressive when they are on-net, and they will sometimes absorb build costs to win an account in a target corridor.
- Lumen Business
Lumen has long-haul and enterprise fiber through Mobile but is not chasing single-site SMB deals. Worth a quote for multi-site customers or anyone needing a wave or transport circuit out of the metro.
- T-Mobile Business
T-Mobile fixed wireless coverage along the Gulf Coast is strong and works well as a secondary circuit or for low-bandwidth retail sites. Not a replacement for DIA, but priced low enough to make redundancy affordable.
- Crown Castle Fiber
Crown Castle has fiber assets in parts of the metro, mostly along major corridors and near carrier hotels. Useful for larger accounts that need a wave or dark fiber path and want to avoid the AT&T and Spectrum default.
- Comcast Business
Comcast has limited presence in the Mobile metro itself but shows up on multi-site deals where a customer has other locations in their footprint. Not a primary local option for a single Mobile site.

Mobile, Alabama market notes
Common questions about business internet in Mobile, Alabama
Is AT&T Business Fiber available at my Mobile address?
AT&T fiber covers a large share of downtown, Midtown, west Mobile along Airport Boulevard, and most of Brookley. The fastest way to check is to run a serviceability check at the address. If you are in a pre-1960 downtown building, fiber may stop at the curb and require a building entry build, which adds time and cost.
What is a fair price for 1Gbps dedicated internet in Mobile?
The Tier C benchmark is $1,195 to $2,000 a month retail. On-net AT&T fiber in a dense commercial block should come in at the lower end, often $1,200 to $1,400 with a 3-year term. Anything above $1,800 needs a reason, usually an off-net build or a single-tenant building. Get a second quote before signing.
Should I use T-Mobile fixed wireless as my primary business internet?
Only if you do not need an SLA and your work tolerates jitter and variable upload. Fixed wireless is a good secondary circuit for redundancy, a good fit for low-bandwidth retail or remote sites, and cheap enough to pair with a real DIA circuit. For VoIP-heavy or transaction-critical operations, use it as backup, not primary.
Why is my Spectrum Business bill higher than my neighbor's?
Spectrum prices the same product differently based on contract date, sales rep, and whether the customer pushed back. Same building, same speed, 30 percent gap is common. Pull your contract end date, get two competing quotes, and call your account team 90 days before the contract clock runs out. Auto-renewal locks in stale pricing.
How long does a new fiber circuit take to install in Mobile?
On-net AT&T or Spectrum fiber is typically 30 to 45 days. Off-net builds requiring new conduit run 60 to 120 days, longer in the downtown historic district because of permitting. C Spire on-net is usually 45 to 60 days. Always get the install timeline in the contract with a service credit if the carrier misses it.
Is C Spire a real option in Mobile or just marketing?
Real, but coverage is uneven. They have built business fiber across parts of the metro and will quote aggressively when your building is on-net. If you are off-net, the build quote can be high or they may pass. Worth getting a quote alongside AT&T and Spectrum, especially if you have multiple sites in Alabama or Mississippi.
