Free IMEI & Carrier Lock Check Online

Free IMEI Check — Lock, Blacklist & Carrier Lookup

Run a free IMEI check to see what a phone’s 15-digit IMEI reveals before you buy or sell it: the device model and storage, which carrier it was made for, whether it’s network-locked, and whether the IMEI has been reported lost, stolen, or blacklisted. No account or sign-up is required. ProFix is a walk-in repair and buy/sell shop at 1712 Mineral Spring Ave in North Providence, RI — serving Providence, Pawtucket, Lincoln, Johnston, and Smithfield.

What an IMEI check can tell you:

• Blacklist status — whether the IMEI has been reported lost or stolen, which can block it from activating on US networks
• Carrier & lock — the original carrier (T-Mobile, AT&T, Verizon, Metro, Boost) and whether the phone is locked to it
• Model & storage — the exact device model and capacity, so a listing matches the real hardware

IMEI check FAQ

How do I find my phone’s IMEI?

Dial *#06# on the keypad and the IMEI appears instantly. You can also find it in Settings → General → About on iPhone, or Settings → About phone on Android — and printed on the original box or SIM tray.

Is the IMEI check really free?

Yes. Enter the 15-digit IMEI and view the result with no account, sign-up, or payment required.

What does a blacklisted IMEI mean?

A blacklisted IMEI has been reported lost or stolen (or flagged for unpaid bills) and can be blocked from activating on US carrier networks. Always check the IMEI before buying a used phone so you don’t end up with a device that can’t connect.

Does a clean IMEI mean the phone is unlocked?

No — blacklist status and carrier lock are separate. A phone can have a clean (not-blacklisted) IMEI and still be locked to a carrier. The check shows both so you know what you’re getting.

Why check the IMEI before buying or selling a used phone?

It confirms the model and storage match the listing and that the device isn’t blacklisted or locked — the two issues that most often make a used phone unusable. Bring the phone to ProFix in North Providence, RI for a free in-store check before any deal.

How do I check if a phone is carrier locked?

Enter the phone’s 15-digit IMEI in the free carrier check above to see the original carrier (T-Mobile, AT&T, Verizon, Metro, or Boost) and whether the device is still locked to it. A carrier-locked phone only works on that network until it’s unlocked.

How do I check if a phone is unlocked with a free IMEI checker?

Use the free IMEI check above — dial *#06# to get the 15-digit IMEI, enter it, and the free IMEI checker reads the network lock status. If it comes back “unlocked,” the phone works on any compatible carrier; if it names a carrier, the phone is still locked to that network. It’s a free carrier check by IMEI, so you can confirm whether a used phone is unlocked before you buy or switch — no account, sign-up, or payment required.

Can I check what carrier a phone is on by IMEI for free?

Yes — this page is a free carrier check. Dial *#06# to see the 15-digit IMEI, enter it above, and the tool shows which carrier the phone belongs to — T-Mobile, Metro by T-Mobile, AT&T, Verizon, or Boost Mobile — along with its lock and blacklist status. Checking a phone’s carrier by IMEI here is free with no sign-up, whether you’re verifying a used phone before buying it or confirming your own device’s network before switching plans.

How does an IMEI carrier check work?

Every phone’s 15-digit IMEI is registered to the carrier that originally sold it. Run the IMEI check above and the carrier lookup reads that record, showing the original network — T-Mobile, AT&T, Verizon, Metro, or Boost — alongside the lock and blacklist status where data is available. An IMEI carrier check is the quickest way to confirm which carrier a used phone came from and whether it will activate on your network before you buy or switch.

When should you run a carrier check on a phone?

Run a carrier check whenever the network a phone belongs to matters: before buying a used phone, so you don’t end up with one locked to a carrier you can’t use; before switching providers with your current phone; or before putting a new SIM into a device that was handed down to you. To check carrier details here, enter the 15-digit IMEI (dial *#06# to see it) and the tool reports the network — T-Mobile, Metro by T-Mobile, AT&T, Verizon, or Boost Mobile — along with lock and blacklist status. Note that a carrier check shows which network the device is registered to, not whose phone plan or number is currently active on it.

What do carrier lock check results mean?

A carrier lock check returns one of three outcomes. “Unlocked” means the phone accepts a SIM from any compatible network — T-Mobile, Metro by T-Mobile, AT&T, Verizon, or Boost Mobile. A named carrier means the phone is still locked to that network: it was sold by that carrier and will reject other SIMs until the lock is removed, which usually requires the device to be fully paid off and meet the carrier’s unlock policy. “Unknown” or no result means the databases the carrier lock checker reads have no record for that IMEI — it does not mean the phone is unlocked, so re-run the imei check carrier lock lookup later or confirm with a SIM from another network. If a free carrier lock check shows a phone you own is still locked, contact the original carrier about an unlock, or stop by ProFix in North Providence, RI for help.
