Choose by connection type and local availability
South Carolina's broadband market includes national providers, regional fiber operators, local cooperatives and wireless services. The most useful comparison is between the plans and technologies offered at the home, not the number of companies advertised statewide.
Cable internet
Spectrum and Xfinity serve portions of South Carolina. Cable networks can offer high download speeds, although standard cable plans often have lower uploads than fiber.
Compare wired providers →5G and fixed wireless
T-Mobile, Verizon and AT&T Internet Air may be alternatives to wired broadband where the address qualifies and wireless conditions are suitable.
Review wireless options →Regional and rural service
Regional providers and electric or telephone cooperatives may operate fiber in communities outside the largest metro networks. Satellite is another option for some remote properties.

What actually matters
Compare more than advertised download speed
Two plans with similar download speeds may perform differently because of upload capacity, network technology, congestion, price structure and home equipment.
Upload speed
Upload capacity matters for video calls, remote work, cloud backups and sending large files. Fiber commonly offers stronger uploads than traditional cable plans.
Regular monthly price
Compare the standard rate after any introductory period. Include equipment, installation, taxes, required bundles and AutoPay or paperless-billing conditions.
Network technology
Check whether the service is fiber-to-the-home, cable, fixed wireless or satellite. Technology can vary between addresses within the same town.
Data policy
Review the plan's broadband label and service terms for data allowances, network management and any usage-related conditions.
Wi-Fi equipment
A fast connection does not guarantee strong Wi-Fi throughout a home. Compare included routers, mesh options, extender charges and compatibility.
Installation and reliability
Ask about professional installation, self-install eligibility, wiring, equipment costs and whether new construction is required at the property.
Speed guide
Check Local Availability
How much internet speed does a household need?
The appropriate speed depends on simultaneous use, file transfers, video calls, streaming and the capabilities of the home network. A multi-gigabit plan is not necessary for every household.
Check Local Availability
100–300 Mbps
Small households and everyday use
Often sufficient for browsing, email, HD streaming, video calls and ordinary connected devices.
300–500 Mbps
Many households
A practical range for multiple streams, remote work, gaming and several devices used at once.
500 Mbps–1 Gbps
Busy households
Useful for heavy simultaneous use, large downloads and households with several active users.
1–3 Gbps
High-demand homes
Can benefit users regularly transferring large files or operating several high-bandwidth devices on a capable network.
5+ Gbps
Specialized multi-gig use
Primarily useful for advanced home networks, large transfers, home labs and multiple simultaneous high-bandwidth workloads.
Connection types
Fiber vs. cable vs. 5G vs. satellite
The connection between a provider network and the home influences upload speed, latency, consistency and availability.
Fiber internet
Fiber-optic lines can provide high bandwidth, symmetrical speeds and low latency. South Carolina has both national and regional fiber networks, but coverage is not uniform across the state.
Cable internet
Cable networks use fiber deeper in the network and coaxial cable for many last-mile connections. They can provide high downloads, while upload capacity depends on the network and plan.
5G home internet
Fixed wireless uses cellular radio networks to connect home equipment. Performance can vary with signal, network load, equipment placement and the service address.
Satellite internet
Satellite service can reach properties beyond many wired networks. Compare latency, equipment costs, weather considerations, plan limits and expected speeds before choosing it.
South Carolina broadband market
Why internet availability changes across South Carolina
South Carolina combines growing metro areas, coastal communities, smaller cities and rural regions. The network serving one community may not extend to the next neighborhood or road.
Metro areas have overlapping networks
Columbia, Greenville–Spartanburg and the Charleston region have a different mix of cable, fiber and wireless options than many rural communities. Even within a metro, network boundaries can be uneven.
Regional providers matter
HTC, Home Telecom, Comporium, Lumos and cooperative networks can be important local choices. A statewide list that focuses only on national brands may overlook the providers most relevant to a particular property.
Rural and coastal locations differ
Outside dense neighborhoods, fiber construction and cable infrastructure may be less extensive. Fixed wireless, satellite or regional telephone-cooperative networks may provide additional options.
South Carolina broadband data
How to verify broadband availability
State mapping tools help identify reported service and technologies, while providers confirm whether a plan can actually be ordered at a specific address.
South Carolina Office of Regulatory Staff
The state's Office of Regulatory Staff Broadband Office maintains broadband mapping resources and works with provider-reported data to examine availability and infrastructure needs.
- Review the state's mapping and data resources.
- Use the South Carolina broadband mapping resources to investigate reported providers and technologies at a location.
- Map information may change as provider submissions and revisions are incorporated.
- Report mapping discrepancies through the contact information published by the state.
Official source: South Carolina Broadband Office.
What an address check adds
A provider's own service checker answers whether that company currently offers plans at the location entered.
- Confirms available plans and connection technologies.
- Shows current advertised rates and offer requirements.
- Can reveal apartment, unit or building limitations.
- Helps establish installation and equipment requirements.
For a purchase decision, verify the service address with each provider being considered. A ZIP-code or map-level listing is not proof that a specific home is serviceable.

South Carolina internet FAQ
Frequently asked questions about South Carolina internet
Information about local provider options, broadband technology, speed, pricing and availability.
What internet providers are available in South Carolina?
Providers serving portions of the state include AT&T, Spectrum, Xfinity, Google Fiber in Fort Mill and Tega Cay, and regional operators such as Lumos, HTC, Home Telecom, Comporium and CarolinaConnect. T-Mobile, Verizon and AT&T Internet Air may offer fixed wireless at eligible addresses. Satellite service may be another option where wired networks are limited.
Is fiber internet available throughout South Carolina?
No single fiber provider covers every South Carolina address. Fiber networks operate in portions of the state, but their boundaries differ by provider and neighborhood. Google Fiber identifies Fort Mill and Tega Cay as South Carolina service areas. Check regional providers and the state broadband map for additional local options.
What is the fastest internet available in South Carolina?
The answer depends on the address. Google Fiber lists plans up to 8 Gbps and identifies Fort Mill and Tega Cay as South Carolina service areas. Other national and regional fiber providers offer multi-gig plans in selected locations. Advertised maximums are not proof that a particular property can order those speeds.
How much does internet cost in South Carolina?
Prices depend on provider, connection type, plan, promotion and address. Some offers require AutoPay, paperless billing or other eligibility conditions. Compare the standard rate, equipment, installation and other charges rather than using a statewide introductory price as a guaranteed cost.
What is the cheapest internet in South Carolina?
There is no single cheapest provider across the state. The lowest-cost available option may be a wired plan, a fixed-wireless service or a qualifying low-cost program. Compare the ongoing price and terms at the actual address before deciding.
Is fiber better than cable internet?
Fiber commonly offers higher upload capacity and symmetrical download and upload speeds. Cable can still provide high download speeds and may be available where fiber is not. Compare actual speeds, latency, price and data terms for the plans offered at the property.
What internet speed does a family need?
Many households can use 300 to 500 Mbps comfortably, depending on the number of simultaneous users and activities. Larger households, frequent large-file transfers or advanced home networks may justify 500 Mbps, gigabit or multi-gig service. Upload speed and Wi-Fi quality also matter.
Does internet availability vary by South Carolina city?
Yes. Provider coverage can change between cities, neighborhoods, streets, apartment buildings and individual addresses. A provider operating in a town does not necessarily serve every property there.
Is 5G home internet an alternative to fiber or cable?
It can be, particularly where wired options are limited or installation of a wired connection is impractical. Performance depends on signal quality, network congestion, equipment placement and provider eligibility. Compare typical performance and plan conditions with available wired options.
Is Google Fiber available in South Carolina?
Google Fiber lists Fort Mill and Tega Cay as South Carolina service areas. Actual availability is address-specific, so use its service checker to confirm that a particular home can order service.
Is Xfinity available throughout South Carolina?
No. Xfinity lists selected South Carolina service areas, including parts of the Charleston region and other communities. Its local service checker should be used to verify availability at a specific address.
Is Spectrum available throughout South Carolina?
Spectrum serves many South Carolina communities, and it also advertises full-fiber service in selected areas. Its network does not cover every address, and the available technology can differ by location.
Are there local internet providers in rural South Carolina?
Yes. Regional providers, telephone companies and cooperatives can be important options outside major metro areas. Investigate providers such as HTC, Home Telecom, Comporium, CarolinaConnect and West Carolina Rural Telephone Cooperative where relevant to the location. Fixed wireless and satellite may provide additional alternatives.
How can I verify internet availability at my home?
Enter the complete service address in each provider's availability tool. The South Carolina Office of Regulatory Staff also maintains broadband mapping and data resources. Maps help with research, but providers must confirm current serviceability and plan details.
