Should you keep Xfinity or switch? Check your account first

Legacy plan or new plan? Read your account

New-plan terms do not rewrite an older account. Your bill and account page show which terms you have.

Audit the existing account

Write down the plan name, the date any discount ends, the leased equipment, any TV or mobile bundle, and whether a data limit applies. Check your actual monthly data use in the Xfinity app. If you pay usage charges, a current unlimited plan may beat changing providers. See Xfinity plans. Our guide to data caps and overage helps you size the heavy months.

Then measure the line: a wired test and a Wi-Fi test at the same hour. A low wired result that repeats is the case to take to Xfinity support before you leave. A weak room is a Wi-Fi problem that a new provider will not fix. If the bill jumped, find the line that changed first.

Fix it inside Xfinity or switch?

Nationally, Comcast, Xfinity’s parent, reports fixed service at 35.5% of US residential locations, and fiber from any provider is reported at 55.9% (FCC National Broadband Map, data as of Dec 31, 2025).

If you own your modem

An owned modem avoids a rental line, but it must suit your plan. Xfinity says to confirm in My Device Info that a device works with Xfinity and supports your speed before you buy it. It also says it won’t install or activate devices it no longer supports (checked Sep 24, 2026). Check your model before any tier change. Read what to look for in a modem and when renting or buying makes sense.

What to compare in the replacement offer

Line the replacement up against your Xfinity account term by term, not headline against headline. Every plan has a broadband label, and the FCC says it must show prices, speeds, fees, data allowances, and bundle, discount and introductory-rate details. Ask for the label for the exact plan at your address and save a copy. Then check five terms on it:

• Upload speed, if anyone works from home or backs up photos.
• Data terms, if a legacy allowance is why you are leaving.
• Equipment: included, rented, or bring your own.
• The later price, and the month it starts.
• The install date, and whether a technician must visit.

If the rival wins only while its promotion lasts, price both over the months you expect to stay. Our guide to the full cost of home internet shows how to line up the price clocks. If the choice is between the 500 Mbps plan and Gig on the same Xfinity account, Xfinity 500 or Gig is that comparison.

Move without an avoidable outage

Get the new provider to confirm, for your exact address and unit, that it will install. Once the new line passes your real work and streaming tests, ask Xfinity for a cancellation confirmation and the date billing stops.

NOW Internet is a separate prepaid product, with its own path. Xfinity says your Xfinity Internet must be disconnected, but it can stay active until the NOW gateway is received and activated. Ask Xfinity to line up both dates. Our prepaid guide covers NOW’s terms.

Close the account with device evidence

List every rented device by serial number. Xfinity accepts returns three ways: its Digital Return Center, which works even after you disconnect; an Xfinity store, where you keep the receipt; or a prepaid UPS label, whose tracking stub is your receipt. Check that the account marks each device as received. The Nov 3, 2026 reading of those routes, and of AT&T’s 21-day window, is return rented internet equipment.

What to do next

Put each option into the 12-month cost calculator. The switching checklist covers the overlap and returns. The legacy-plan check comes first because our methodology counts data allowance and equipment among an offer’s material terms.
