How to Cancel Xfinity Mobile (2026 Guide)

To cancel Xfinity Mobile, call 1-888-936-4968 — and use the call to negotiate your Internet bill, where the real savings hide. Keeping your number? Port instead so the line closes itself.

The most valuable part of the call is asking about Internet retention.

To cancel Xfinity Mobile, call 1-888-936-4968 (or general Xfinity 1-800-934-6489) — it can't be fully canceled online for most customers. The call runs 30–45 minutes. If you're keeping your number, don't cancel: port to your new carrier, and the transfer closes your Xfinity Mobile line automatically. Canceling Mobile does not cancel Xfinity Internet.

Key takeaways
Call 1-888-936-4968 — online cancellation is limited to callback requests.
Keeping your number? Port instead — canceling releases it.
Always ask about Internet retention — the biggest saving on the call.
Mobile prorates the final bill; device balances still come due.
Port, don't cancel, to keep your number
Canceling first releases your number. Switching carriers? Follow the port process and let the completed transfer close the line.

How to cancel

  1. Call 1-888-936-4968 (Mobile) or 1-800-934-6489 (general Xfinity).
  2. Verify identity (account number, PIN, ZIP).
  3. Decline Mobile retention — but do ask about Internet retention (see below).
  4. Get a cancellation confirmation number and disconnection date in writing.

Only the Primary Account Holder can cancel. Chat and the online form usually schedule a callback rather than finalize; corporate stores can cancel in person. Xfinity Mobile phones run on Verizon's network, so a paid-off, unlocked device works on Visible, US Mobile, Total Wireless, and often AT&T/T-Mobile too.

The hidden win: negotiate Internet
Xfinity retention often controls both Mobile and Internet pricing. Even if you're only canceling Mobile, ask about Internet retention — unadvertised discounts of $20–$40/month are common. Many people save more here than by canceling Mobile.

Fees, timing, and after

  • No ETF on standard Mobile plans; device installments come due in full and promo credits stop.
  • Xfinity Mobile usually prorates the final wireless bill (unlike the Big 3).
  • Canceling Mobile ends the Mobile+Internet bundle discount — Internet may rise $5–$15/mo.
  • Turn off auto-pay first if you want to review charges.
  • Mobile-only cancellations rarely have equipment to return; keep your Internet gear if you're keeping Internet.
Canceling to save money?

Visible and US Mobile use Verizon's network — the same one Xfinity Mobile runs on — for less, and porting takes 30 minutes.

Frequently asked questions

Does canceling Xfinity Mobile cancel my Internet? +
No — they're separate. Internet continues, but the bundle discount ends and the bill may rise $5–$15/mo. Ask about Internet retention on the same call.
Can I cancel Xfinity Mobile online? +
Only partly — the online form typically schedules a retention callback. Full cancellation needs a phone rep or a corporate store.
Does Xfinity Mobile charge a cancellation fee? +
No ETF on standard plans. You still owe device installments in full and forfeit promo credits; the final wireless bill usually prorates.
Will my Xfinity Mobile phone work elsewhere? +
Yes if paid off and unlocked — it's a Verizon-network device, compatible with Visible, US Mobile, Total Wireless, and often AT&T/T-Mobile.
