Miami's business internet market behaves differently because the buyer mix is different. A large share of demand comes from Latin American banking, international trade, and cruise/hospitality operators who need real cross-border capacity, not just office connectivity. That pulls in carriers focused on international transit and cable landing stations, which adds competitive pressure at the high end. Brickell and the CBD have dense on-net fiber and competitive pricing. Once you move into Doral, Hialeah, or the warehouse belt near MIA, the on-net map thins out fast and prices jump. The other quirk: storm season changes how serious buyers think about diversity and SLA credits. Real physical path diversity matters here in a way it does not in Atlanta or Dallas.
Miami and the surrounding south Florida metro have stronger carrier choice than they did five years ago. AT&T Business Fiber covers a growing share of commercial blocks. Comcast Business is everywhere. Hotwire Communications has a strong presence in some buildings. Crown Castle and Lightpath both have meaningful fiber footprints in the metro.
The pricing problem in Miami is the seasonal contract cycle. Many businesses sign 24 or 36-month contracts in the summer hiring slowdown and never look at them again, which means the auto-renewal hits at the busiest part of the season.
Miami's commercial center
Miami's commercial demand sits in three big places. The Central Business District holds the legal, banking, and government corridor along Flagler Street and Biscayne Boulevard. Brickell, just south of the Miami River, has filled in over the past two decades as the metro's largest concentration of Latin American banking and Class A office tenancy. The Arts and Entertainment District, north of the CBD, anchors a mix of cultural institutions, hospitality, and creative-office tenants. Jackson Health System, the public-hospital network covering Miami-Dade County, and the University of Miami's Leonard M. Miller School of Medicine are two of the largest commercial accounts in the metro and drive a substantial share of enterprise telecom demand.
In 2025, Lightpath expanded its Miami network to connect the Hollywood Cable Landing Station and said its Miami system had grown to more than 80 route miles of underground fiber, adding meaningful local fiber capacity for international and data center traffic. One pricing wrinkle: The Miami Downtown Development Authority is funded by a special tax levy on properties within its district, which adds a district-specific cost layer for downtown owners and businesses, often passed through in commercial leases.
What you should be paying
These are dedicated internet ranges from current carrier wholesale data, marked up to typical retail.
Miami dedicated internet, typical retail (mid 50%)
Monthly recurring charge, dedicated internet access (DIA). Numbers are derived from current carrier wholesale quotes.
| Speed | Typical retail (mid 50%) | Sample size |
|---|---|---|
| 100 Mbps | $630 – $765/mo | n = 1 |
| 500 Mbps | $955 – $1,160/mo | n = 1 |
| 1 Gbps | $1,195 – $1,455/mo | n = 1 |
| 10 Gbps | $2,190 – $2,660/mo | n = 1 |
If your bill sits above the high end of the band, you are likely overpaying.
Analyze My Bill FreeFor AT&T Business Fiber broadband, a 1 Gbps line should land between $180 and $260 a month. For Comcast Business coax at 600 Mbps, expect $150 to $230. Anything above $310 on coax is a sign of an aged contract.
Carriers worth quoting in Miami
Six carriers cover most addresses in the metro.
- AT&T Business Fiber. Strong commercial fiber footprint, especially in Brickell, downtown Miami, and the Aventura area.
- Comcast Business. Coax everywhere, fiber in select buildings.
- Hotwire Communications. Strong building-specific footprint, especially in Brickell condo towers and select commercial properties.
- T-Mobile Business Internet. $85 a month for 200 to 300 Mbps. Useful benchmark.
- Crown Castle Fiber. Common in downtown commercial buildings.
- Lightpath. Now expanded into south Florida, mid-market fiber.
If you have not had three of these on a quote sheet, you have not run a real comparison.
What to do this week

Carriers worth a quote here
- AT&T Business
AT&T's Miami fiber footprint has grown materially in Brickell, the CBD, and along the Biscayne corridor. On-net pricing is competitive against Comcast, but Doral and the western industrial parks still see off-net build quotes that inflate the NRC.
- Comcast Business
Comcast covers nearly every commercial block in Miami-Dade and Broward and dominates the SMB broadband segment. Locally they rarely move on MRC, but they will quietly drop modem rental and Wi-Fi activation fees if you push.
- Lightpath
Lightpath has 80+ route miles of underground fiber in Miami and connects the Hollywood Cable Landing Station. Strongest fit for enterprise, data center, and international transit buyers in Brickell, NAP of the Americas, and the Doral data center cluster.
- Crown Castle Fiber
Crown Castle has a real on-net footprint in the CBD, Brickell, and along the major dark fiber routes south to Homestead. Usually priced as a wholesale alternative to the ILECs, which makes them a useful third quote when AT&T and Comcast both come in high.
- Lumen Business
Lumen is on-net in most Class A towers in Brickell and downtown, plus the major carrier hotels. They are currently hungry for business and more negotiable than they were two years ago, especially on wave and DIA above 1 Gbps.
- Spectrum Business
Spectrum's coax footprint covers most of the metro outside the urban core and is the default broadband option in Hialeah, Kendall, and the Miami Lakes corridor. Pricing follows national patterns, with the usual equipment and Wi-Fi fees attached.
- Verizon Business
Verizon is not an ILEC in Florida, so wireline fiber coverage is selective and concentrated in enterprise buildings. Mostly relevant for multi-site customers who want a single national contract, or for fixed wireless backup in harder-to-reach industrial locations.
What internet costs in Miami, Florida right now
Miami, Florida market notes
Common questions about business internet in Miami, Florida
Why does my Miami office pay more than the AT&T quote for a similar address in Tampa?
Two reasons. First, Miami's commercial real estate concentration means more Class A on-net buildings, but also more landlord access fees and riser charges that carriers fold into the MRC. Second, if your building is off-net, the local loop usually rides a competing carrier's fiber, which adds cost. Ask for an on-net confirmation in writing before you compare quotes.
Is dedicated internet worth it in Miami, or is business broadband enough?
Depends on your use case. If you run VoIP for a call center, cloud-hosted EMR, or any workload that breaks when upload slows down, DIA pays for itself. If you are a standard office with cloud productivity tools and occasional video calls, business fiber broadband at 500 Mbps to 1 Gbps is usually fine. The price gap is roughly $200 versus $1,200 a month at 1 Gbps, so the use case has to justify it.
How do I get real redundancy in a Miami office building?
Get two carriers with confirmed separate physical paths into the building. That means different street entrances, different risers, and different splice points, not just different logos on the invoice. Carriers resell each other's local loops constantly in Miami, so a second circuit can ride the exact same fiber as your primary. Demand written path diversity confirmation before you sign.
When is the best time to renegotiate a contract in Miami?
Start 90 to 120 days before your contract end date. End of quarter and end of year are when carrier reps are most flexible on discount. Avoid the summer slowdown for the actual negotiation, since reps are slower to respond and decision-makers on your side are often out. The auto-renewal window is usually 30 days, sometimes 60. Calendar it.
Does hurricane season affect SLA credits or service availability?
Hurricane-related outages are typically excluded from SLA credits as force majeure, so do not count on credits for storm downtime. What you can negotiate is a lemon clause: three outages in 30 days gives you the right to cancel without ETF. Also ask for a documented restoration priority tier if your business is healthcare, finance, or critical infrastructure.
Which Miami neighborhoods have the best fiber competition?
Brickell and the CBD have the deepest on-net coverage, with AT&T, Comcast, Lumen, Crown Castle, and Lightpath all competing for the same buildings. Wynwood and the Arts and Entertainment District have improved a lot in the past three years. Doral, Hialeah, and the warehouse corridors near MIA are thinner, which means fewer competing quotes and higher off-net build costs.
