Fiber and cable connections typically deliver latency under 20ms, while satellite services may experience 500-600ms delays that affect interactive applications.

Pricing Breakdown: Total Cost of Ownership

The advertised monthly rate represents just one component of your total internet cost. CenturyLink (Quantum Fiber) starts at $30/mo, while Tds begins at Contact for pricing.

Coverage & Availability: Geographic Reach

CenturyLink (Quantum Fiber) operates from its headquarters in Monroe, LA, serving customers in select areas where fiber infrastructure has been deployed. Tds provides service throughout its coverage area, with availability varying significantly by location.

Availability varies significantly even within a provider's service area. CenturyLink (Quantum Fiber) is expanding its fiber network but currently serves limited geographic areas, with availability concentrated in specific cities and neighborhoods, while Tds serves specific geographic regions, with availability varying considerably even within its stated service area. Urban and suburban areas typically enjoy access to multiple providers and technologies, while rural locations may have limited options.

Technology availability within a service area creates another layer of complexity. A provider's fiber network may only reach certain neighborhoods, with older DSL or cable infrastructure serving other areas. This results in dramatically different experiences for customers nominally served by the same provider—fiber users enjoy symmetrical gigabit speeds while DSL customers struggle with 25 Mbps connections.

Contract Terms & Fees: Understanding Commitments

CenturyLink (Quantum Fiber) does not require a contract, providing flexibility to cancel service without penalties. Tds offers no-contract service, allowing you to cancel anytime without financial penalties.

No-contract service provides valuable flexibility for renters, seasonal residents, or anyone uncertain about their long-term housing situation.

You can cancel anytime without early termination fees, making these options ideal for renters, students, or anyone who values the ability to change providers without financial penalty. However, verify whether month-to-month plans cost more than contracted rates.

Price lock guarantees protect customers from mid-contract rate increases, but not all providers offer this protection. Without a price lock, your monthly bill can increase at the provider's discretion, even during your contract term. Read promotional terms carefully to understand whether your rate is guaranteed and for how long.
