Fees vary by plan and location. The fees shown apply to most plans; check with the provider for costs specific to your plan.

When comparing internet providers, remember that advertised prices rarely tell the complete story. Equipment fees alone can add $10-15 per month to your bill, while installation charges, early termination fees, and data overage penalties can significantly increase your total cost of service. Consider these additional costs alongside monthly rates when determining which provider offers the better value for your specific needs.
