Quick Decision Guide
✓ Choose fiber (AT&T, Frontier, Google Fiber) if: You work from home with video calls, are a serious gamer needing low latency, do content creation or upload large files, or have multiple heavy users in your household. Fiber's symmetrical speeds are unmatched.
✓ Choose cable (Spectrum, Xfinity, Cox) if: Fiber isn't available at your address, you mainly stream video content, you want wide availability and reliability, or Spectrum's unlimited data is important to you.
✗ Avoid fiber if: It's not available at your address (always check first), you're on a tight budget under $50/mo, or you don't need fast upload speeds.
✗ Avoid cable if: You upload large files frequently, you need the lowest possible latency for competitive gaming, or data caps are a concern (except Spectrum).
→ Choose T-Mobile 5G instead if: You want no contracts or credit checks, need quick 15-minute self-install, fiber/cable aren't available, or you're renting and may move soon.

How the Availability Checker Tool Works
Our availability checker tool helps you make informed decisions about your internet service by providing accurate, up-to-date information tailored to your specific location. The tool queries multiple data sources including provider coverage databases, FCC broadband data, and real-world performance metrics to deliver actionable results in seconds.
Enter your address or select your location to see personalized results. The system cross-references provider coverage maps with plan pricing, speed tiers, and availability at your exact address. Results are updated regularly to reflect new provider offerings, coverage expansions, and pricing changes. Use the filters and sorting options to compare providers by the criteria that matter most to you.
Understanding Your Results
The results displayed by the availability checker tool include key metrics to help you evaluate your options. Download and upload speeds indicate the maximum throughput available on each plan. Monthly pricing shows the current rate including any promotional discounts. Technology type tells you whether the connection uses fiber, cable, DSL, wireless, or satellite, which affects performance characteristics beyond just speed.
Pay attention to details beyond speed and price. Contract requirements, data caps, equipment fees, and installation charges all affect the true cost and flexibility of each option. Plans marked as promotional will increase to the regular rate after the specified period. Use these details to calculate the total cost over 12-24 months for the most accurate comparison between providers.
Tips for Getting the Best Results
For the most accurate results from the availability checker tool, enter your complete street address including apartment or unit number. Internet availability can vary between units in the same building, so specificity matters. If you are comparing options for a future move, enter the new address to see what will be available at your destination.
Compare results across multiple criteria rather than focusing solely on speed or price. A slightly more expensive plan with better upload speeds and no data cap may deliver better value for a remote-working household than the cheapest plan with slower uploads and a 1 TB data limit. Consider your household's specific usage patterns, peak usage times, and the number of simultaneous users when evaluating which option best meets your needs.
