eSIM-Only Phones Are Spreading. What That Means for Switching Carriers

Apple's iPhone 18 Pro and Pro Max, in stores since September 18, 2026, have no SIM tray in the US, the fifth straight year of eSIM-only iPhones here. For anyone changing carriers, the switch becomes a download instead of a card swap. The carrier lock still decides what you can do, though. Verizon phones activated since January 13, 2026 no longer unlock automatically 60 days after activation, so a financed phone from any of the three big carriers now stays locked to that carrier, and can't take another company's eSIM, until the balance is paid.

Key takeaways

Every iPhone model launched in the US since the iPhone 14 (September 2022) is eSIM-only, according to Apple. So are the US Pixel 10, 10 Pro, 10 Pro XL, 11, 11 Pro and 11 Pro XL; Google's US spec pages show a nano-SIM slot on the Pixel 10a and both Pro Folds.
The new carrier sends a digital SIM by QR code, app or automatic activation, but your number still moves the old way: with your account number and a transfer PIN from your current carrier.
The FCC waived Verizon's 60-day unlocking rule on January 12, 2026, for phones activated from the next day. Those phones unlock once paid in full (postpaid) or after 365 days of paid service (prepaid).
A locked phone can't use another carrier's eSIM, including most travel eSIMs.
An eSIM can't be pulled out of a stolen phone, but criminals can still talk a carrier into moving your number. Free carrier locks block that, and they block your own switch until you turn them off.

What it means for you

iPhone owners (iPhone 14 or later bought in the US): there is no SIM card to fall back on. Moves between iPhones, or between iPhone and Android, now happen in Settings if your carrier supports them.
Pixel and other Android users: the US Pixel 10, 10 Pro, 10 Pro XL, 11, 11 Pro and 11 Pro XL are eSIM-only; the Pixel 10a and the Pro Folds still take a nano-SIM. Many other Android phones keep a tray, so check your model's spec page.
Financed or prepaid phones: the lock, not the eSIM, is what stops a switch or a second carrier's eSIM. The unlocking table below shows each carrier's rule. A Verizon phone activated on or before January 12, 2026 falls under the old 60-day terms.
Travelers: a travel eSIM works only on an unlocked phone, which can then keep your home number for calls and texts.
Anyone who uses text-message codes: eSIM doesn't end number hijacking. Use your carrier's SIM and port-out locks, and switch them off only on switching day. T-Mobile iPhone users should read the note on SIM Protection below.

Which phones no longer take a SIM

An eSIM (embedded SIM) is a chip built into the phone that a carrier programs remotely, instead of a removable card. The FCC's eSIM guide notes that people with unlocked phones can change providers by reprogramming it in the phone's settings.

Apple removed the SIM tray from US models in September 2022. Its SIM type list (updated September 17, 2026) and Google's eSIM help page and US spec sheets for the Pixel 11, Pixel 11 Pro Fold and Pixel 10a show where each model stands (checked October 5, 2026):

Phone	eSIM-only where	Elsewhere
iPhone 14, 15 and 16 families (including 16e)	US only	eSIM plus nano-SIM tray
iPhone 17, 17e, 17 Pro, 17 Pro Max, 18 Pro, 18 Pro Max	US, US Virgin Islands, Guam, Canada, Mexico, Japan, UAE, Saudi Arabia, Bahrain, Kuwait, Qatar, Oman	eSIM plus nano-SIM tray
iPhone Air	Everywhere	No tray in any country
Pixel 10, 10 Pro, 10 Pro XL; Pixel 11, 11 Pro, 11 Pro XL	US models	Nano-SIM plus eSIM in other markets
Pixel 10a, Pixel 10 Pro Fold, Pixel 11 Pro Fold	Not eSIM-only	Nano-SIM plus eSIM in the US

Apple's iPhone 18 Pro announcement explains the trade: the tray's space now holds a larger battery, worth two more hours of video playback. The catch for travelers is that a local SIM card from an airport kiosk won't fit; local service has to come as an eSIM.

How a switch works without a SIM

Changing carriers involves two separate steps, and eSIM changes only the second.

The number moves (porting). You give the new carrier your old account number and a transfer PIN. The new carrier requests the number, and the old carrier releases it and closes that line.
The phone gets a new SIM profile. Apple's eSIM setup page lists the routes: eSIM Carrier Activation (the plan appears during setup when you buy through the carrier), a QR code, a carrier link or app, and eSIM Quick Transfer.

Quick Transfer is often mistaken for a way to switch carriers. It moves a line you already have from an old iPhone to a new one without calling the carrier, if the carrier supports it. Both phones need iOS 18.4 or later, the same Apple Account and Bluetooth turned on, and the old SIM is deactivated once the new one is active. It does not change your carrier.

The PIN step at the big three

Leaving	What to ask for	Who can request it	Valid for	Lock to turn off first
Verizon	Number Transfer PIN (dial #PORT or use My Verizon)	Account Owner or Account Manager	7 days	Number Lock
AT&T	Number Transfer PIN (myAT&T, AT&T app or dial *PORT)	User with primary online access	4 days (14 for business)	Wireless Account Lock
T-Mobile	Temporary Port Out PIN (T-Life app or T-Mobile.com), plus the account PIN	Primary Account Holder only	Not stated	Port Out Protection

Carrier support pages checked October 5, 2026. All three say not to cancel the old service yourself: the port closes it. If you disconnect first, Verizon and AT&T say you'll have to reactivate the number before the move can go through. AT&T adds that it never calls to ask for your passcode or transfer PIN.

Moving between iPhone and Android

Apple now supports direct transfers in both directions, with the phones side by side on Wi-Fi and Bluetooth. Android to iPhone needs an iPhone 11 or later on iOS 26 and an Android 16 phone; US carriers include AT&T, T-Mobile, Verizon, Cricket, FirstNet and Xfinity Mobile. iPhone to Android needs iOS 26.3 and a compatible Android 17 phone, with AT&T, FirstNet, T-Mobile or Verizon. Either way, the number stops working on the old phone when the transfer completes.

Locked phones: the real barrier

A locked phone runs only on the carrier that sold it, eSIM or not. Apple's Dual SIM guide says that to use two carriers, the carrier must unlock the iPhone or both plans must come from the same carrier.

Verizon used to be the exception. A 2007 FCC rule tied to its 700 MHz C Block licenses barred it from locking phones at all; a 2019 waiver let it lock them for 60 days after activation, and its 2021 purchase of Tracfone extended that 60-day policy to Tracfone's prepaid brands. On January 12, 2026, the FCC's Wireless Telecommunications Bureau waived that rule, citing handset theft and trafficking. Verizon committed instead to the industry's voluntary CTIA code: postpaid phones unlock once paid in full, prepaid phones no later than a year after activation. FCC Chairman Brendan Carr said in the announcement that with the waiver, "we now have a uniform industry standard." The waiver covers phones that became active on Verizon's network from January 13, 2026, the day after the order; earlier activations keep the old terms. It lasts until the FCC settles on an industry-wide approach.

That approach is still open. In July 2024 the FCC proposed requiring every carrier to unlock phones 60 days after activation unless it found fraud in that window. The January 2026 order calls the proposal pending, and no final rule had appeared in the Federal Register as of October 5, 2026.

Carrier	Postpaid phone unlocks when	Prepaid phone unlocks when
Verizon	Paid in full or bought at full retail price; automatic (phones activated from Jan. 13, 2026)	After 365 days of paid, active service; automatic
AT&T	Bought 60+ days ago, paid in full, account current	After 12 months of paid service
T-Mobile	Active at least 40 days; paid in full if financed or leased	After 365 days, or sooner with more than $100 in refills per line and more than 14 days since purchase

Policies as of October 5, 2026. All three refuse phones reported lost, stolen or tied to fraud, and make exceptions for deployed military personnel. Verizon delays the unlock by 35 days if a Verizon Gift Card pays off the phone.

Illustrative example: a Verizon customer

Take a $1,199 phone (the iPhone 18 Pro's US starting price) financed over 36 months and activated on Verizon on September 18, 2026, ignoring taxes, fees and promotional credits.

monthly payment = price / months = 1,199 / 36 = about $33.31
balance after k payments = 1,199 − (33.31 × k)
after 9 payments: 1,199 − 299.79 = about $899.21
old 60-day rule: unlocked November 17, 2026, whatever the balance
CTIA terms: locked until paid off, about September 2029 on schedule

A customer who leaves Verizon after nine months owes about $899 either way, because Verizon's port-out FAQs say any remaining device balance must be paid when the number moves. The waiver mostly hurts customers who stay. Under the old rule, this phone could have taken a travel eSIM or a second carrier's line from mid-November 2026. Now it can't until the roughly $899 is paid early or the plan runs its course in 2029. If the deal included an optional promotional monthly discount with a minimum term, leaving early also means repaying the discounts received, which Verizon caps at a rolling six months.

Travel eSIMs need an unlocked phone

The FCC's guide notes that travelers can add a plan for the country they're visiting. On an unlocked iPhone with two lines, both numbers can call and text, but only one carries cellular data at a time. Check your home carrier's international rates before using the home line abroad. A phone still locked to its carrier will reject another company's travel eSIM, so check unlock status weeks before a trip.

eSIM swap fraud and carrier locks

An eSIM can't be stolen without stealing the phone, the FCC's guide notes. That ends card theft, but not the attack the FCC's rules target: persuading your carrier to move your number to a SIM, physical or digital, in a phone the criminal holds, then reading your text-message codes. The FCC's SIM swap rules, adopted November 15, 2023, define a SIM as "a physical or virtual card," so eSIM changes are covered.

Those rules require secure customer verification before a number moves, immediate notice of SIM change and port-out requests, and account locks. But a July 5, 2024 waiver paused compliance until federal paperwork review ends and the FCC announces a compliance date in the Federal Register. As of October 5, 2026, the regulation text still says compliance isn't required until a date is added, and no notice had been published.

Carriers' own free locks fill the gap:

T-Mobile Port Out Protection blocks transfers to another carrier. The Primary Account Holder turns it off; on prepaid accounts, any line user can ask T-Mobile to remove it after an extra security check.
T-Mobile SIM Protection is described differently on two of its pages. Its account-fraud page says you'll get an error if you change SIM cards or move your eSIM to a new device without turning it off first. Its SIM Protection page says the feature "does not prevent eSIM transfer on Apple devices" and is for postpaid customers only, while the fraud page also gives prepaid steps. On an iPhone, keep Port Out Protection on as well and confirm with T-Mobile how SIM Protection treats your line. The account-fraud page adds that only the Primary Account Holder can remove it.
Verizon SIM Protection and Number Lock block SIM or device changes and number transfers. SIM changes stay blocked for 15 minutes after SIM Protection is turned off.
AT&T Wireless Account Lock blocks number transfers while it is on, according to its transfer PIN page.

Frequently asked questions

How long does moving my number take?

For mobile numbers moving to T-Mobile, the carrier says a transfer typically finishes in 10 minutes to 3 hours, depending on whether your details match the old account. Other carriers may differ. You may have service on both phones for up to 24 hours. If you call 911 in that window, T-Mobile says to stay on the line, because 911 may not be able to call you back.

Will my old carrier charge me for leaving?

Verizon says it charges no fee to move a number out. You may still owe an early termination fee if your line has an unfinished minimum term, the remaining device balance, and, if you took an optional promotional monthly discount with a minimum term, the discounts received so far, capped at a rolling six months. Moving your last line also means canceling connected devices such as a watch or tablet. This is general information, not legal or financial advice; check your own agreement before you act.

What should I do with my old phone's eSIM?

The FCC advises wiping the eSIM data before you sell, give away or recycle a phone, following the maker's and carrier's instructions. For an older phone with a physical card, remove it and store it securely or destroy it.

Can one phone hold my home line and a work line?

Yes, on most recent phones. An iPhone with Dual SIM keeps both numbers able to call and text, and the US Pixel 11 runs two active eSIMs while storing eight or more. If the lines come from different carriers, the phone must be unlocked.

Do I still need a store visit to activate an eSIM?

Usually not. Google's SIM transfer page says a transfer can happen automatically during setup, depending on the carrier, when both phones run Android 12 or later with current Google Play Services and a screen lock. If the phone doesn't detect it, Google says to contact the carrier to activate the eSIM, which Apple also lists as the fallback.

Before you switch: a checklist

Check your phone's unlock status against the table above; pay off the balance first if you need to. A Verizon phone activated on or before January 12, 2026 should already be unlocked under the old 60-day terms; ask Verizon if it isn't.
Confirm the new carrier supports your exact model, and back up the phone.
On sign-up day, turn off your SIM and port-out locks, then request the transfer PIN. AT&T's expires after 4 days and Verizon's after 7; T-Mobile doesn't say.
Give the new carrier your account number and PIN. Never share them with anyone who calls you.
Install the new eSIM, and keep the old line active until the number works on the new one.
Turn on the new carrier's SIM and port-out locks.
Wipe the old phone, including its eSIM, before selling or recycling it.
