How to Switch Wireless Carriers in 2026: AT&T, Verizon, and T-Mobile Cancellation & Porting Guide

Americans overpay on their wireless bills by an estimated $40-$70 per month on average, according to multiple consumer advocacy analyses. The problem is not that better plans do not exist — it is that switching carriers feels like navigating a minefield of early termination fees, device locks, and porting confusion.

The carriers know this. They design the exit process to be just frustrating enough that most people give up and keep paying. AT&T makes you wait 48 hours after paying off your device before you can unlock it. Verizon added a 35-day waiting period in February 2026 for online device payoffs. T-Mobile caps you at unlocking just 2 devices per year.

This guide breaks down everything you need to know to leave AT&T, Verizon, or T-Mobile in 2026 — the fees, the device unlock timelines, the porting process, and the strategies that save you the most money. No fluff, just the specific numbers and steps.

Carrier-by-Carrier Comparison at a Glance

Ease of Leaving: Carrier Rankings

We scored each carrier from 0 (hardest to leave) to 100 (easiest) based on ETF structure, device unlock speed, porting friction, and transparency of the exit process:

T-Mobile leads largely because of its tiered ETF structure (you pay less the closer you are to the end of your contract), automatic device unlocking, and the shortest active-service requirement at 40 days. Verizon ranks last because of its February 2026 policy change adding a 35-day waiting period for online device payoffs — a deliberate friction point that did not exist before.

AT&T: Cancellation and Switching Details

AT&T's exit process is moderately difficult. The early termination fees are high, the device unlock requirements are specific, and there is a mandatory 48-hour cooling period after paying off your device before you can request an unlock.

Early Termination Fees

• Smartphones: Up to $325 for consumer accounts
• Basic phones/tablets: Up to $150
• Business accounts: Up to $750
• Proration: The ETF decreases by $10 for each completed month of your contract. If you are 20 months into a 24-month contract, your smartphone ETF would be approximately $125 instead of $325.
• No ETF if you are on a no-contract plan or have completed your contract term

Device Unlock Policy

To unlock your AT&T device, all of the following must be true:

• Device was purchased at least 60 days ago
• Device is paid in full (installment plan balance is $0)
• You have waited 48 hours after making the final payment before requesting the unlock
• Device has not been reported lost or stolen
• Account is in good standing (no past-due balance)
• Prepaid devices: Must wait 6 months from activation before unlock is eligible

Porting Away from AT&T

1. Get your AT&T account number — find it on your bill or in the myAT&T app under Account > Manage Account
2. Get your account PIN/passcode — this is the 4-8 digit PIN you set when you opened the account. If you do not remember it, reset it in the myAT&T app or call 800-331-0500
3. Note your billing zip code — you will need it for the port request
4. Provide these to your new carrier — they will initiate the port. Do not contact AT&T to cancel.

Other Fees to Watch

• Activation fee: Up to $50 per line when initially setting up service
• Restocking fee: Up to $55 for returning a device within the 14-day return period (waived for online purchases returned in-store)
• Non-return equipment fee: $150-$200 if you fail to return your gateway/router after canceling internet service
• 14-day return period for new devices — you can return the device and cancel within 14 days with a full refund minus the restocking fee

Verizon: Cancellation and Switching Details

Verizon has the highest ETF of the three major carriers, and a February 2026 policy change made leaving even harder by adding a 35-day waiting period for device payoffs made online or through the app. This is the most carrier-hostile exit process in 2026.

Early Termination Fees

• Smartphones: Up to $350 (the highest among the Big Three)
• Basic phones/tablets: Up to $175
• Proration: Decreases by $10 for each completed month. A smartphone ETF at month 20 of a 24-month contract would be approximately $150.
• No ETF if you are on a month-to-month plan or your contract has ended

Device Unlock Policy (Updated January/February 2026)

Verizon overhauled its unlock policy in early 2026. The rules depend on when your device was activated:

Devices activated after January 2026 (FCC waiver approved January 12, prepaid changes effective January 20):

• Postpaid: Device is unlocked after it is paid in full (subject to the 35-day wait below for online payoffs, effective February 18, 2026)
• Prepaid: Device is unlocked after 365 days of paid and active service (changed from the previous 60-day auto-unlock)

The 35-day wait (February 2026 change):

• If you pay off your device balance online or through the My Verizon app, there is a mandatory 35-day waiting period before the device is unlocked
• To avoid this wait: Pay off your device balance in person at a Verizon corporate store. In-person payoffs bypass the 35-day hold entirely.
• This policy was introduced in February 2026 and is widely seen as a deliberate retention tactic

Porting Away from Verizon

1. Turn off Number Lock — In the My Verizon app, go to Account > My Plan > Number Lock and toggle it off. If Number Lock is on, the port will fail.
2. Get your Number Transfer PIN — Dial #PORT (#7678) from your Verizon phone, or generate the PIN in the My Verizon app under Account > My Plan > Number Transfer PIN
3. Get your Verizon account number — Available on your bill or in My Verizon under Account
4. Note your billing zip code
5. Give all of this to your new carrier — They handle the port from there

Verizon customer service: 800-922-0204

T-Mobile: Cancellation and Switching Details

T-Mobile has the most consumer-friendly exit process of the three major carriers. Its ETF structure is tiered (not a single high number), it automatically unlocks eligible devices, and it aggressively recruits switchers by offering to pay your old carrier's fees.

Early Termination Fees

T-Mobile uses a tiered ETF structure that decreases based on how much time is left on your contract:

• More than 180 days remaining: $200
• 91-180 days remaining: $100
• Less than 91 days remaining: $50
• Less than 30 days remaining: $50 or one monthly service charge, whichever is less
• No ETF if on a no-contract or month-to-month plan

This tiered approach means T-Mobile's maximum ETF ($200) is $125-$150 less than AT&T's and Verizon's maximums.

Device Unlock Policy

• Device must have been active on T-Mobile's network for at least 40 days
• T-Mobile automatically unlocks devices within 2 business days of becoming eligible (if the device supports remote unlock)
• You do not need to request an unlock — it happens automatically once the 40-day requirement and payment conditions are met
• Prepaid devices: Must wait 365 days from activation or have at least $100 in total refills
• Limit: T-Mobile allows a maximum of 2 device unlocks per 12-month period per account

Porting Away from T-Mobile

1. Get your T-Mobile account number — Find it in the T-Mobile app under Account > Account Info, or on your bill
2. Get your account PIN — The 6-15 digit PIN set during account creation. Reset it in the T-Mobile app or call 800-937-8997
3. Note your billing zip code
4. Provide these to your new carrier — They will handle the porting process

Switching TO T-Mobile: Get Up to $800 Per Line

T-Mobile is currently the most aggressive at recruiting switchers. Their Family Freedom program offers:

• Up to $800 per line toward early termination fees and device payments at your old carrier
• Requirements: Trade in your current device, purchase a new device from T-Mobile, and activate a new line on a qualifying plan
• Reimbursement comes as a prepaid Mastercard typically within 15 days after submitting your final bill from the old carrier
• Up to 4 lines per account are eligible, so a family of four could receive up to $3,200 in total switching credits

Head-to-Head: ETF Comparison Over Time

Here is what your early termination fee looks like at different points in a 24-month smartphone contract:

T-Mobile's tiered structure is consistently the cheapest option to leave. By month 9, T-Mobile's ETF drops to $100 while AT&T and Verizon are still above $230. If you are mid-contract and planning to switch, T-Mobile customers have the lowest financial barrier at every stage.

The 9-Step Switching Process

Whether you are leaving AT&T, Verizon, or T-Mobile, the process follows the same sequence. Do these steps in order.

Step 1: Check your contract status and device balance

Log into your carrier's app or website and find out:

• Are you still under contract? If yes, what is the ETF?
• Do you have a remaining device installment balance? If yes, how much?
• When does your current billing cycle end?

Step 2: Gather your account information

You will need three things from your current carrier:

• Account number (on your bill or in the carrier app)
• Account PIN or password (the one you set when you opened the account)
• Billing zip code associated with the account

Step 3: Make sure your phone is unlocked

• AT&T: Pay off device, wait 48 hours, request unlock via att.com/deviceunlock
• Verizon: Pay off device in person at a corporate store to avoid the 35-day wait
• T-Mobile: If your device has been active for 40+ days and is paid off, it should auto-unlock within 2 business days

Step 4: Confirm device compatibility with your new carrier

Not every phone works on every network. Check your new carrier's IMEI compatibility tool:

• AT&T: att.com/idpassport/global/login.html
• Verizon: verizon.com/bring-your-own-device
• T-Mobile: t-mobile.com/bring-your-own-phone

Enter your phone's IMEI (dial *#06# on any phone to display it) and verify compatibility.

Step 5: Choose your new carrier and plan

Compare plans across carriers. Pay attention to:

• Monthly cost after all fees and taxes
• Data limits and throttling thresholds
• Switching incentives (T-Mobile's $800/line offer, carrier-specific trade-in deals)
• Family plan pricing if you are porting multiple lines

Step 6: Initiate the number port with your new carrier

Go to your new carrier (online, in-store, or by phone) and tell them you want to port your existing number. Provide your old carrier's account number, PIN, and billing zip code. The new carrier handles the port request — you do not need to contact your old carrier.

Step 7: Activate your new SIM or eSIM

Once the port is initiated, your new carrier will provide a SIM card or eSIM activation. Follow their instructions to activate. During the brief porting window (minutes to hours), you may temporarily lose service on both carriers. This is normal.

Step 8: Verify everything works

After activation, test all three:

• Make a phone call — confirm voice service works
• Send a text message — confirm SMS/MMS works
• Load a website on cellular data — confirm data service works

If any of these fail, contact your new carrier's support immediately.

Step 9: Confirm old account cancellation

Your old carrier account should auto-cancel once the port completes. Log into your old carrier's app or website within a few days to confirm:

• Your number is no longer listed on the account
• There are no unexpected charges beyond your final prorated bill and any ETF
• Return any leased equipment (routers, gateways) to avoid non-return fees

Smart Strategies for Switching

Time your switch to minimize costs

• Switch near the end of your billing cycle to minimize the prorated charges on your final bill
• If you are under contract, calculate whether waiting a few more months drops your ETF enough to save money overall
• Take advantage of holiday promotions — carriers offer their most aggressive switching deals during Black Friday, back-to-school season, and the holiday quarter

Consider MVNOs for massive savings

You do not have to switch between the Big Three. Mobile Virtual Network Operators (MVNOs) use the same towers at a fraction of the price:

• Verizon ($75/mo) → Visible ($25/mo): Save $600/year — same Verizon network
• AT&T ($65/mo) → Cricket Wireless ($30/mo): Save $420/year — same AT&T network
• T-Mobile ($50/mo) → Mint Mobile ($15/mo annual): Save $420/year — same T-Mobile network
• US Mobile was rated the #1 cell phone provider by Consumer Reports in 2026, offering plans starting at $25/month on your choice of Verizon, T-Mobile, or AT&T towers

Leverage switching incentives

• T-Mobile's Family Freedom pays up to $800/line toward your old ETF and device balance for up to 4 lines switching from AT&T or Verizon
• Most carriers offer enhanced trade-in values when you port a number from a competitor
• Stack incentives: trade-in credit + switching credit + new-customer promotional pricing can often be combined

Pay off devices strategically

• Verizon: Always pay off in person at a corporate store to avoid the 35-day wait
• AT&T: Pay off the device at least 48 hours before you plan to initiate the switch
• T-Mobile: If your device auto-unlocked, you are ready to switch immediately after payoff

Keep your old account active

Never call your old carrier to cancel. The porting process handles cancellation automatically. If you cancel first, your phone number enters a recycling queue and may be permanently lost within as little as 30 days.

Back up everything before you switch

Before initiating the port:

• Back up your contacts to iCloud, Google, or a local backup — contacts stored only on the SIM card may not transfer
• Save voicemails you want to keep — visual voicemail archives are carrier-specific and will be lost after cancellation
• Download any carrier-specific app data — AT&T Call Protect logs, Verizon Smart Family settings, and T-Mobile Scam Shield preferences will not transfer to the new carrier
• Note your current plan details — screenshot your plan, usage, and any promotional pricing in case you need to reference it during a billing dispute on the final bill

Check for carrier-specific perks you will lose

Before switching, review what benefits are tied to your current carrier:

• AT&T: ActiveArmor security, HBO Max legacy plans (if applicable), AT&T Wi-Fi hotspot access
• Verizon: Disney+ or Netflix bundle inclusions, Verizon Cloud storage, +play streaming hub credits
• T-Mobile: T-Mobile Tuesdays perks, free Netflix on certain plans, in-flight Wi-Fi benefits
• Cancel or migrate any third-party services tied to your carrier before the port completes

Frequently Asked Questions

Will I lose my phone number if I switch carriers?

No — as long as you do not cancel your old service before the port completes. When you give your new carrier your account number, PIN, and zip code, they transfer your number directly. Your old account auto-cancels after the port finishes.

Can I switch carriers if I still owe money on my phone?

Yes, but you will need to pay off the remaining device balance before your old carrier will unlock the phone. The device balance and any ETF will appear on your final bill. Some new carriers (like T-Mobile, up to $800/line) will reimburse you for these costs.

How long does number porting take?

The FCC requires wireless carriers to process simple ports within 1 business day. In practice, most ports complete within 2-4 hours. Complex ports involving business accounts or multiple lines may take longer.

What is the difference between an ETF and a device balance?

An early termination fee (ETF) is a penalty for ending your service contract before it expires. A device balance is the remaining amount you owe on your phone's installment plan. These are two separate charges, and both may appear on your final bill. Many consumers are on no-contract plans and only have a device balance, not an ETF.

Can I keep my phone when I switch carriers?

Yes, if your phone is paid off and unlocked. After unlocking, check compatibility with your new carrier's network using their IMEI checker tool. Most modern phones (iPhone 12 and newer, recent Samsung Galaxy models) are compatible with all three major carriers.

What happens to my family plan if one person leaves?

When one line ports away from a family plan, that line is removed from the account. The remaining lines stay active, but the per-line pricing may increase since many family plan discounts are based on the number of active lines. Check your plan's pricing tiers before one member switches.

Does Verizon's 35-day wait apply to all devices?

The 35-day waiting period applies specifically to devices that are paid off online or through the My Verizon app and were activated after January 13, 2026. Paying off the device in person at a Verizon corporate store bypasses this wait entirely.

What if the port fails or gets stuck?

Port failures are uncommon but usually happen because of one of three reasons: (1) the account information you provided does not match exactly (account number, PIN, zip code), (2) Number Lock is still enabled (Verizon), or (3) there is an outstanding balance blocking the port. Contact your new carrier first — they can usually see the rejection reason and tell you exactly what to fix. If the issue is on the old carrier's side, call their support line with your port request details.

Can I switch carriers and keep my current device plan?

No. Your device installment plan is a contract with your current carrier. When you leave, the remaining balance becomes due immediately. You can either pay it off in full or, in some cases, your new carrier's switching incentive will reimburse you. The device itself is yours to keep once the balance is paid and it is unlocked.

What about eSIM transfers?

If your current phone uses an eSIM (no physical SIM card), the process is slightly different. You will need to contact your new carrier to provision a new eSIM profile for their network. Most carriers can do this in-store or through their app. Your old carrier's eSIM profile will be deactivated once the port completes. iPhones running iOS 16 and later support eSIM Quick Transfer, which can streamline this process when switching between carriers that support it.

Pre-Switch Checklist

Before you walk into a new carrier's store or start the online switching process, confirm every item on this list:

• [ ] Contract status confirmed — know your ETF amount or confirm you are month-to-month
• [ ] Device balance checked — know the exact remaining amount owed on your phone
• [ ] Device paid off — balance is $0 (pay in-store for Verizon to avoid the 35-day wait)
• [ ] Device unlocked — confirmed via carrier app or by inserting a different carrier's SIM
• [ ] Account number written down — from your bill or carrier app
• [ ] Account PIN/password confirmed — the PIN you set at account creation, not your app login
• [ ] Billing zip code noted — matches what is on file with your carrier
• [ ] Device compatibility verified — checked IMEI on new carrier's website
• [ ] Data backed up — contacts, photos, voicemails, and app data saved
• [ ] Old service still active — do NOT cancel before porting

The Bottom Line

Switching wireless carriers in 2026 is entirely doable, but the carriers have made it deliberately inconvenient. T-Mobile is the easiest to leave, with the lowest ETFs ($50-$200 tiered), automatic device unlocking after 40 days, and the most aggressive switching incentives at $800 per line. AT&T sits in the middle with its $325 ETF and mandatory 48-hour post-payoff unlock wait. Verizon is the hardest to leave after its February 2026 policy change that added a 35-day hold on online device payoffs — but you can sidestep it entirely by paying off your device at a corporate store.

The golden rule: never cancel your old service before porting your number. The port triggers the cancellation automatically, and doing it out of order risks permanently losing your phone number. Gather your account number, PIN, and zip code; make sure your device is unlocked; walk into your new carrier; and let them handle the rest. Most switches complete within a single business day.

If you are on the fence about switching, run the math: calculate your current monthly cost including all fees and device payments, compare it to what the new carrier offers (including any switching credits), and factor in the one-time ETF or device payoff. For many Americans, the savings over a 12-month period far exceed the upfront switching costs.
