Find internet providers in Columbia, SC
Find internet offered in Columbia, SC – easily compare options from multiple providers to find the plan that best fits your needs.
FindBetterInternet was created by two guys with years of first-hand industry experience selling internet services online. Frankly, what we found left a lot to be desired. Internet providers can pay for their listings to be placed higher up the page, cookies can be captured, and your data can be shared for banner ads that stalk your online profile for the next week. We built FindBetterInternet to be different.
Our methodology translates the complex treasure trove of 115m locations on the FCC Broadband Map into one simple resource. We layer on pricing to help you sift through what’s good value.
We hope this is helpful for you and appreciate all the community’s support with this project. If you find it helpful, we do make a commission if you buy internet from a link on our address-check page. We pour that back into maintaining the site.
Every price and coverage figure on this site traces back to FCC Broadband Data Collection filings (the National Broadband Map); here’s exactly how we do it.

The 30-Second Verdict
UpdatedIn Columbia, SC, your best bet is AT&T, covering about 92% of the city overall. Its fiber reaches about 40% of the city with speeds up to 5,000 Mbps, while Spectrum is close at 89.6% overall, mostly cable reaching about 87% with speeds up to 1,000/35 Mbps. Spectrum leads ZIP 29201 and ZIP 29202 at 48.2% and 44.4%, respectively, though AT&T fiber with speeds up to 5,000 Mbps reaches 17.6% and 18.5% there. Shandon is nearly even, Spectrum at 49.3% and AT&T at 48.3%, while Cottontown favors Spectrum at 43.8% but has AT&T fiber at 29.2% and Lumos at 5.7%. Rosewood still merits an address check, and 29206 is a major AT&T pocket, with fiber at 72.5%. For students near the University of South Carolina, Benedict College, Allen University, or Columbia College, ask whether housing has fiber or older AT&T copper, which reaches about 25% of the city and can frustrate Zoom, streaming, and gaming. T-Mobile offers budget fixed wireless with speeds up to 100/20 Mbps across about 50% of the city, while Verizon reaches about 55% at up to 300/20 Mbps. Coverage changes street to street, especially around Fort Jackson and student apartments, so confirm the exact address.

THE TAKEAWAY
Our recommendation for Columbia
At $95/mo for the first 12 months, then $135/mo, AT&T Fiber 5 GIG offers up to 5000 Mbps down and 5000 Mbps up, earning a 99/100 Speed Score and making it a top-tier option that is above the city average of 76. Its fiber plan is available to 40.1% of the city, so availability depends on your address. Where fiber is unavailable, AT&T Internet Air offers up to 300 Mbps down and 300 Mbps up, but fixed wireless can be less consistent than fiber.
About AT&T
AT&T offers excellent value: $35/mo for the first 12 months buys Fiber 300 with up to 300 Mbps both ways, $50/mo buys Fiber 1 GIG with up to 1000 Mbps both ways or Fiber 500 with up to 500 Mbps both ways, and $95/mo buys Fiber 5 GIG with up to 5000 Mbps both ways, although promotional prices increase after 12 months. These fiber plans are excellent for streaming, gaming, work, and large households, but availability is address-dependent, ranging from 40.1% of Columbia for Fiber 5 GIG to 44.7% for Fiber 1 GIG, Fiber 500, and Fiber 300. Where fiber is unavailable, Internet Air costs $55/mo for up to 300 Mbps both ways and reaches 40.5% of the city, but fixed wireless can be less consistent for busy households, so check your address for fiber first.

Our recommendation for Columbia
Households seeking affordable internet for streaming, browsing, and everyday work may find T-Mobile’s 5G fixed wireless service a practical fit, with Rely offering up to 354 Mbps download and 55 Mbps upload for $50/mo promotional pricing, or All-In offering up to 498 Mbps download and 55 Mbps upload for $70/mo promotional pricing. Both plans have a 78/100 Speed Score, about the same as the city average of 76, and are available to 73.0% of Columbia. Because fixed wireless performance can vary by address and network conditions, check availability at your specific home and compare wired options if you need the most consistent connection.
About T-Mobile
Households looking for good everyday speeds without needing fiber or cable may find T-Mobile a good fit, with All-In Home Internet offering up to 498 Mbps download and 55 Mbps upload for $70/mo promotional pricing, or Rely Home Internet offering up to 354 Mbps download and 55 Mbps upload for $50/mo promotional pricing. Both are 5G fixed wireless plans with a Speed Score of 78/100 and availability at 73.0% of Columbia, but service quality is address-dependent and this technology is adequate rather than excellent, so check for faster wired options first if your home needs highly consistent performance for gaming, heavy uploads, or many simultaneous users.

Columbia Internet FAQs
What is the fastest internet provider in Columbia, SC?
The fastest listed speed is 5,000/5,000 Mbps fiber: AT&T reaches 40.1%, Lumos approximately 9%, and TruVista approximately 3% of Columbia. AT&T is the first availability check because its fastest fiber footprint is largest, but the address must qualify for that tier.
Can I get fiber internet in Columbia, SC?
Yes—AT&T Fiber 300 reaches 44.7% of Columbia, and Lumos fiber reaches approximately 9%. ZIP results vary: AT&T fiber reaches 48.3% in 29205 and 72.5% in 29206, so check your exact address rather than relying on citywide coverage.
What is the cheapest internet in Columbia, SC?
Spectrum Internet Advantage is the cheapest city plan at a promotional starting rate of $30/mo for 100 Mbps, reaching 87.1% of Columbia. It offers the lowest listed price while covering most addresses, but availability still requires an address check; Spectrum's overall provider coverage is 89.6%.
How much internet speed do I need for my Columbia household?
For a shared Columbia household, start with 100 Mbps; Spectrum Internet Advantage reaches 87.1% at a $30/mo promotional starting rate. If several users stream or game simultaneously, Spectrum Internet Gig provides 1,000 Mbps and reaches the same 87.1%, subject to address verification.
Is fiber internet available in Shandon, Columbia, SC?
Yes—AT&T's listed 5,000/5,000 Mbps fiber reaches 48.3% in ZIP 29205 (Shandon). Spectrum cable is listed at 49.3% there, so compare both technologies at your specific address instead of assuming fiber is universal.

Not all connections are equal. We weight each technology based on real-world reliability and performance:
- Fiber: 100% – Fastest, most reliable technology
- Cable: 85% – High speeds, shared neighborhood bandwidth
- Fixed Wireless (Licensed): 70% – Dedicated spectrum, weather-dependent
- Copper/DSL: 65% – Distance-limited, aging infrastructure
- Fixed Wireless (Unlicensed): 60% – Shared spectrum, variable performance
- Satellite (LEO): 40% – Low-earth orbit (e.g., Starlink), higher latency
- Satellite (GEO): 15% – Geostationary orbit, significant latency
Percentile Ranking:
After calculating raw scores, we rank every service option in your state by geographic coverage (census blocks served). A score of 85 means this service performs better than 85% of all internet options available in your state.
Data Source: FCC National Broadband Map data, updated twice a year.
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.
