How to Cancel Mint Mobile: The Short Answer
To cancel Mint Mobile, you port your number out to another carrier before your current plan expires, or you let the plan lapse without renewing and then contact support to close the account. Mint has no long-term contract, so there is no early termination fee — but there is also no prorated refund on prepaid time you have already paid for. If you cancel mid-cycle, the remaining weeks of service simply expire with the plan. Mint Mobile was acquired by T-Mobile in 2024, and the brand continues to operate as a prepaid MVNO running on T-Mobile’s network.
Option 1: Port Your Number Out (The Usual Path)

Porting is how most people leave Mint. It takes one step that matters most: start the port before your Mint plan expires. If your plan lapses first, the number can be released and reclaimed, and getting it back is not guaranteed.
Porting also acts as the cancellation. In the U.S., once a number successfully moves to a new carrier, the old line is disconnected automatically. You do not need to call Mint first, and calling to cancel before porting can actually kill the port, because a cancelled line is no longer eligible to be transferred.
What you need before you start
- Account number — found in the Mint account dashboard or by asking support.
- Transfer PIN — request it in the app or from support; it is separate from your account password.
- The phone number itself — the one being ported.
- Billing name and address — must match what Mint has on file, character for character, or the port will be rejected.
- Your Mint account left active — do not cancel the line while a port is pending.
Give all of that to your new carrier. Ports on the same network backbone often complete in minutes; cross-carrier ports can take a few hours to a couple of business days. During the overlap, keep both SIMs in the phone if it supports dual SIM.
Option 2: Let It Expire and Close the Account
If you do not care about keeping the number, the simplest route is to turn off auto-renew and let the plan run out.
- Log in and disable auto-renewal so no card charge fires at the end of the cycle.
- Note the exact expiration date — service stops at the end of the paid period, not at the end of the calendar month.
- After expiry, contact support to have the account closed and any stored payment method removed.
Leaving it to expire costs you nothing extra, but you lose the number. If anyone uses it for two-factor authentication — banks, work logins, delivery apps — update those before the number goes dark.
Renewal Timing: Where People Get Caught
The most common complaint about leaving Mint is a charge that lands sooner than expected. Mint sells in 3-, 6-, and 12-month blocks, and auto-renewal is on by default. Two things to watch:
- Renewal is triggered by the plan end date, not by your billing anniversary comfort zone. A 12-month plan bought in March renews the following March.
- Renewal charges can post a day or two before the expiry date to avoid a service gap. If you are cutting it close, turn auto-renew off well in advance — not on the last day.
- Cards on file can fail or expire, which sometimes buys you a grace window, but do not count on that as a cancellation method.
Prepaid time, refunds, and unused days
| Situation | What typically happens | Money back? |
|---|---|---|
| Port out on day 5 of a 12-month plan | Line disconnects, remaining ~360 days forfeited | No prorated refund |
| Port out on day 355 of 365 | Same outcome, minimal loss | No refund, but little left to lose |
| Cancel inside the 7-day return window (new activations) | Device/plan return may qualify | Possible full or partial refund |
| Auto-renew already charged, you cancel the next week | New term is active; support may goodwill-credit | Case-by-case, not guaranteed |
| Multi-month plan with a promo price | Promo pricing is tied to the full term | No refund of discounted value |
The practical takeaway: if you are within a month or two of expiry, waiting costs almost nothing. If you are early in a 12-month plan and switching, you are writing off the difference — decide whether the new carrier’s savings over that window actually cover it.
Before You Switch: A Few Practical Checks
- Device compatibility. Mint is a T-Mobile MVNO, so a phone that worked on Mint will generally work on T-Mobile and other T-Mobile-based MVNOs immediately. Moving to AT&T or Verizon usually works too, but confirm your exact model supports the new carrier’s bands — especially for VoLTE calling.
- Unlock status. If you bought a phone through Mint on a payment plan, it must be paid off and unlocked before another carrier will activate it. Budget time for that.
- Family and multi-line accounts. Port each line individually. Partial ports on a shared account can leave the remaining lines on a changed plan or price.
- Data add-ons and wallet balance. Any prepaid credit sitting in the account typically does not transfer and is not refunded.
- Referral credits. Credits earned from referrals generally vanish with the account.
Typical timeline when porting out
| Step | Time |
|---|---|
| Request account number and transfer PIN from Mint | Minutes, via app or support chat |
| Submit port request with new carrier | 10–20 minutes |
| Port completion (same network family) | Minutes to a few hours |
| Port completion (different network) | A few hours to 2 business days |
| Final Mint billing cycle closes | End of the paid period |
Common Follow-Up Questions
Do I have to call Mint to cancel?
No. A completed port cancels the line for you. You only need to contact support if you want the account formally closed, if you are not porting, or if there is a billing issue.
Can I get a refund for unused months?
Generally no. Mint’s model is prepaid multi-month service, and the discount you received is tied to committing to the whole term. Exceptions exist mainly around the return window on brand-new activations and device purchases, and sometimes as a goodwill credit if a renewal charge just posted.
What happens to my phone number if I just stop paying?
The line expires at the end of the paid period, and after a holding window the number goes back into the carrier’s pool. Once reassigned, it cannot be recovered. If the number matters at all, port it before expiry.
Will I lose my voicemail and call history?
Voicemail messages stored with Mint are not portable and disappear with the account. Call logs and texts live on the phone itself, so they stay — but back up anything important before swapping SIMs.
Can I keep using the phone after cancelling?
Yes, as a Wi-Fi-only device, or by inserting a SIM from another carrier once the handset is unlocked and compatible. There is no need to buy a new phone just because you left Mint.
Is there any penalty for leaving early?
No early termination fee, because there is no contract. The “penalty” is simply the forfeited value of prepaid days you will not use.
Bottom Line
Port first, cancel never — the port itself closes the line, and it is the only way to keep your number. Turn off auto-renew the moment you decide to leave, note the exact expiry date, and plan your switch for late in the term rather than early. Sort out two-factor codes and any phone payment plan before the port, and treat unused prepaid time as sunk cost rather than something to chase.
