The 30-Second Verdict
UpdatedRoles count plans reaching at least 5% of Longmont. Faster only in small pockets: Quantum Fiber Fiber 8G up to 8,000 Mbps (~0% of the city).
Xfinity is the best overall, with cable speeds up to 2,000 Mbps reaching about 17% of Longmont, while its overall footprint reaches about 73% of the city. Where Xfinity’s top cable tier is unavailable, CenturyLink is the safe backup, mostly DSL, with its overall footprint reaching about 87% and its fastest common DSL tier offering up to 140 Mbps to about 19% of the city.
NextLight is the standout in Old Town Longmont, covering about 84% of 80501 with fiber speeds up to 1,000/1,000 Mbps, while Xfinity reaches about 10% there. In 80503, NextLight leads at about 59%, Xfinity’s largest share is about 19%, and fiber alternatives remain limited, with Quantum Fiber at about 5%. Prospect New Town in 80504 has a more mixed picture, led by NextLight at about 39% and Xfinity at about 23%, while TDS Telecom appears only in a small slice. ZIP 80502 is especially fiber-friendly, with NextLight reaching about 91%. Students at Front Range Community College Boulder County Campus should check apartment-specific wiring, since older DSL or copper infrastructure can complicate Zoom, streaming, and gaming. Fixed wireless from Verizon, T-Mobile, or Vistabeam may fill gaps, but coverage changes street to street, so confirm the exact address.

THE TAKEAWAY
Our recommendation for Longmont
CenturyLink is a mixed choice in Longmont: its fiber plan is a good option, while its DSL plan offers limited performance compared with alternatives. Fiber provides up to 940 Mbps both ways with a Speed Score of 79/100, but is available to only about 3% of the city, while the DSL plan reaches about 36% and offers up to 100 Mbps download and 10 Mbps upload with a score of 30/100. Because the stronger technology may not reach your address, check availability there and consider checking other providers first if only DSL is offered.

About CenturyLink
CenturyLink is a good option mainly for addresses that qualify for its fiber plan, but its DSL offering is only adequate for basic internet needs. Fiber customers can get up to 940 Mbps both ways for $75 per month, though it is available to only about 3% of Longmont, while the 100 Mbps DSL plan reaches about 36% and has a 10 Mbps upload speed. Check your address for fiber or another faster provider first, since the DSL fallback may feel limiting for streaming, video calls, and multiple users.

THE TAKEAWAY
Our recommendation for Longmont
At $94.99/mo for the first 12 months, then $119.99/mo, HughesNet’s Fusion plan buys up to 100 Mbps download and 5 Mbps upload, but its satellite connection has a 30/100 Speed Score and falls below Longmont’s city average of 68. Satellite offers limited performance compared with alternatives, so consider checking what other providers offer at your address before choosing this plan, even though Fusion is listed as available to 100.0% of Longmont.
Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.
About HughesNet
HughesNet costs $39.99 to $94.99 per month for the first 12 months, then $49.99 to $119.99, but the satellite plans provide only up to 25 Mbps, 50 Mbps, or 100 Mbps download and have below-average Speed Scores, so check for faster internet before choosing it. Every plan is available to 100.0% of Longmont, making HughesNet a broad-coverage fallback for basic use, though satellite latency and limited upload speeds may not suit streaming, gaming, video calls, or a busy household.

THE TAKEAWAY
Our recommendation for Longmont
Viasat is a limited-performance satellite option compared with alternatives in Longmont, despite offering coverage across 100% of the city. Its Viasat Essentials plan offers up to 55 Mbps download and 4 Mbps upload with a Speed Score of 26/100, below the city average of 68, and is available to 100% of the city. The Viasat Unleashed plan is slower at up to 34 Mbps download and 4 Mbps upload, with a Speed Score of 14/100, so check what other technologies are available at your specific address before choosing.
Speeds and reach below are what the provider files with the FCC for each technology tier, by census block. The plans it actually sells here, with their own speeds and prices, are under Pricing & Plans; the two can differ.
About Viasat Inc
Viasat Inc is mainly an adequate fallback, not a first choice, because its satellite plans offer below-average speeds and satellite service can have higher latency. Viasat Essentials is the better option, with up to 55 Mbps download and 4 Mbps upload for $69.99 per month and availability to 100% of Longmont, while Viasat Unleashed offers up to 34 Mbps download and 4 Mbps upload for $99.99 per month. Check your address for fiber or cable first, since those technologies are generally much better suited to modern streaming, video calls, and multiple connected devices.

How We Analyze Internet in Longmont
FCC Broadband Data
We use the FCC National Broadband Map, updated twice a year with provider-reported coverage at the census block level.
Speed Score
A state-wide percentile of each plan’s maximum advertised download speed against every option filed with the FCC in the state, all technologies on one scale. It is not a measured speed test.
Coverage Calculation
Provider coverage shows what percentage of census blocks in Longmont report service availability from each provider.
Data Coverage for Longmont
How We Calculate Speed Score
The Speed Score is a state-wide percentile from 0 to 100. It answers one question: of every internet option filed with the FCC in this state, across every technology, what share is slower than this plan’s maximum advertised download speed?
What goes in:
- The plan’s maximum advertised download speed, as the provider files it with the FCC and lists it for sale.
- Every other serviceable option in the state from the FCC Broadband Data Collection, counted by the census blocks it reaches.
Speed Score = share of the state’s filed options with a lower advertised download speed
A score of 85 means this plan’s advertised speed beats 85% of the options filed in the state. Fiber, cable, DSL, fixed wireless and satellite are all on the same scale, so a 1,000 Mbps plan scores the same whoever sells it.
What it is not: a measured speed test. It does not include latency, upload speed, reliability or congestion. Real throughput at an address varies with wiring, equipment and time of day.
How providers are ordered on this page: each provider’s tier scores are averaged across the census blocks it serves, then multiplied by the share of the city it reaches. Wired providers rank ahead of wireless-only ones, and satellite last, because their filings describe a signal footprint rather than a plant. The same rule sets the title and the 30-second verdict.
Data source: FCC National Broadband Map (Broadband Data Collection), republished roughly twice a year; provider plan lists checked monthly.
How We Calculate Capabilities
Estimated Capabilities predict how well each internet plan supports common household activities based on speed requirements and connection type.
Rating Scale:
- Excellent – Optimal performance, handles peak usage easily
- Good – Reliable performance with minimal issues
- Fair – Functional but may experience slowdowns during heavy use
- Poor – Not recommended; expect frequent buffering or lag
How We Rate Each Category:
Streaming
Based on download speed. 4K streaming requires 25+ Mbps per stream; HD requires 5+ Mbps. We account for multiple simultaneous streams.
Multi-device
Evaluates total bandwidth capacity divided by typical household device count (phones, tablets, smart TVs, computers). Fiber and cable handle many devices better than DSL or satellite.
Gaming
Considers both upload speed (for sending game data) and latency (ping time). Fiber and cable excel here; satellite connections struggle due to inherent signal delay.
Whole Home
Assesses whether the connection can reliably serve an entire household during peak evening hours. Factors in technology type (shared vs. dedicated bandwidth) and total speed capacity.
Note: Actual performance depends on your specific location, network congestion, and equipment quality.
