How to Check if Your Phone Is Unlocked (Verizon, AT&T)

The fastest check: open Settings, search for Carrier Lock on iPhone and read the answer, No SIM Restrictions means unlocked. On Android, Samsung shows it under Network unlock, and a Pixel tells you by which networks it can see. Two minutes, no store visit. A locked phone will refuse any SIM or eSIM from outside its home carrier, which makes this the single most important check before buying travel data, and the one most people skip until an eSIM fails at an airport.

What a carrier lock actually is

A lock is software, not hardware. Carriers subsidise phones through instalment plans and protect the subsidy by restricting the phone to their network until it is paid off. A locked AT&T iPhone is physically identical to an unlocked one, it just refuses credentials from anyone but AT&T, and that refusal covers travel eSIMs completely. No workaround exists on the phone itself, the carrier flips the flag from their side, which is why checking before you fly matters: an unlock request made during the trip can take days you do not have.

How to check if an iPhone is unlocked

Settings, General, About, scroll to Carrier Lock. No SIM Restrictions is the answer you want, it means any carrier's SIM or eSIM will work. If it says SIM Locked, or names your carrier, the phone is locked and needs the carrier's unlock process before a travel eSIM will install. While you are in About, this is a good moment to confirm eSIM capability itself, and our compatible devices page lists every model that qualifies, with the odd regional exception flagged.

How to check if an Android phone is unlocked

Samsung: Settings, Connections, More connection settings, Network unlock, on models that have it. It reads Network locked or Network unlocked. Pixel: Settings, Network and internet, SIMs, tap the SIM, then turn Automatically select network off. If the list shows networks from only one carrier, the phone is probably locked, and networks from several carriers usually means it is unlocked. Trying to add an eSIM is not a safe test, because on some locked phones the profile installs and then never connects.

The old dial code trick, *#06# for the IMEI, still matters for a different reason: some carrier unlock forms and third party checkers want the IMEI number, and that code shows it on almost any phone.

How to get a Verizon, AT&T or T-Mobile phone unlocked

Every major carrier unlocks for free once conditions are met, the phone is paid off and the account is in good standing. AT&T unlocks a postpaid phone on request once it is paid off and has been on the account for 60 days, or after 6 months of prepaid service. T-Mobile unlocks a paid off postpaid phone after 40 days of service, and a prepaid one after 365 days or $100 of refills. Verizon used to unlock every phone automatically 60 days after purchase. In January 2026 the FCC let it drop that rule, so a newer Verizon phone now stays locked until it is paid off, and a prepaid one needs 365 days of service. Phones bought before the change may still unlock at 60 days, so check yours rather than assume. Prepaid phones on all carriers carry longer waits, often a year of service. If you are inside those windows with a trip coming, apply now, approvals often land in hours but the guarantee is days.

Buying secondhand? Ask the seller for the unlock status before money moves, and verify with the settings check above the moment the phone is in your hands. An eBay bargain that is locked to a carrier you have never heard of is a paperweight for travel purposes until that carrier agrees otherwise.

Why this bites eSIM travellers specifically

With a plastic SIM, a locked phone fails obviously: the foreign SIM goes in, the phone says invalid SIM, everyone understands. With an eSIM the failure is quieter. The profile may download, sit in settings looking installed, and simply never connect, which sends people down every wrong troubleshooting path before the real cause surfaces. It is one of the checks in our eSIM not working guide because it hides so well. The two minute settings check before purchase skips the whole mystery.

One related but different thing: a handful of phones, mostly sold in mainland China, ship without eSIM hardware at all regardless of lock status. That is a capability question rather than a lock question, and the same devices page answers both.

Unlocked and eSIM capable? You are ready

That is the whole qualification. Any plan from our 198 countries will install and connect, prices start at $1.29, and the install takes five minutes on home WiFi, walked through in our setup guide. The dual line arrangement, home SIM for your number, travel eSIM for data, is covered switch by switch in our roaming settings guide.

Unlock questions before you travel

How do I check if my phone is unlocked for eSIM?

iPhone: Settings, General, About, Carrier Lock, where No SIM Restrictions means unlocked. Android: search SIM lock in settings or begin adding an eSIM, a locked phone announces itself before anything installs.

Can I check if a phone is unlocked without a SIM card?

On iPhone and Samsung, yes. The Carrier Lock and Network unlock screens work with no SIM in the phone. The Pixel network list needs a SIM inserted.

Will a travel eSIM work on a locked phone?

No. A carrier locked phone rejects all outside lines, physical or digital. The lock has to be removed by the carrier that applied it, which is free once their conditions are met.

How long does carrier unlocking take?

Verizon no longer unlocks new phones automatically at 60 days. Since January 2026 a Verizon phone unlocks once it is paid off, or after 365 days on prepaid. AT&T unlocks a paid off phone on request after 60 days on the account. T-Mobile unlocks a paid off phone after 40 days of service. Prepaid devices wait longer everywhere, so check well before the trip, not at the gate.
