Step-by-Step Switching Guide

1. Check Frontier Availability

Before doing anything, confirm Frontier Fiber serves your address. Cox and Frontier overlap in several markets including Arizona, Louisiana, Virginia, and parts of Florida.

2. Order Frontier Fiber

Place your order online and schedule installation. Keep your Cox service active until Frontier is installed. During installation, a Frontier technician will:

Install the fiber terminal (ONT) if not already present
Set up your free eero Wi-Fi router
Test your connection and ensure everything works

3. Check Your Cox Contract

Log into your Cox account to check:

Contract status: Many Cox plans require a 1 or 2-year commitment
Early termination fee: Typically $10/month for each remaining month in your contract (e.g., 6 months left = $60 ETF)
Billing cycle: Cancel near the end of your billing cycle to avoid paying for unused days (Cox doesn't prorate final bills in most areas)

4. Cancel Cox

Cox offers these cancellation methods:

Phone: Call 1-800-234-3993
In-store: Visit a Cox Solutions Store with your photo ID
Online: Some markets allow cancellation via the Cox app or website

Be prepared for retention offers. Cox may offer temporary discounts to keep you — decide in advance if any discount would change your mind.

5. Return Equipment

Return all Cox equipment within 10 business days to avoid unreturned equipment fees of $200-$400:

Return at any Cox Solutions Store (get a receipt!)
Ship via UPS with the prepaid label Cox provides
Document everything: Photo the equipment, keep tracking numbers, save the return receipt

6. Verify Final Bill

Review your final Cox bill for accuracy. Dispute any charges for: unreturned equipment (if you have proof of return), service dates after cancellation, or incorrect early termination fees.

Save $600+/Year vs. Cox

Frontier Fiber 1 Gig: faster upload, no data caps, half the price.
