How to Check IMEI and Find Out If a Phone Is Locked
What Is an IMEI and Why Is Checking It Essential?
When purchasing a pre-owned smartphone, it is crucial to know how to check the IMEI and find out if the phone is locked. The IMEI (International Mobile Equipment Identity) is a unique 15-digit number assigned to every mobile device. It allows you to easily verify whether a phone has been reported lost or stolen, placed on a blacklist, or locked to a specific foreign carrier (SIM-Lock).
How to Find Your Phone's IMEI Code
You can find the IMEI code using several quick methods:
- Universal dial code: Open your phone app, dial *#06#, and the 15-digit number will automatically appear on the screen.
- In Settings: On Apple devices, go to Settings > General > About. On Android devices, go to Settings > About Phone (or About Device).
- Physical inspection: Check the SIM card tray or the original box. Make sure the number shown in the system settings matches the one printed on the tray or box.
How to Check If a Phone Is Locked
Once you have the IMEI, check the following key factors:
1. Checking Carrier Lock Status
If the phone was imported from the US, it might be locked to a specific network provider (such as AT&T, T-Mobile, or Verizon):
- Checking on iPhone: Go to Settings > General > About and look for the Carrier Lock field. If it says No SIM restrictions, the device is Factory Unlocked and will work with any carrier worldwide.
- Hands-on test: Insert a local SIM card (Magti, Silknet, Cellfie). If it catches signal within seconds and can make a call, the device is unlocked.
2. Checking the International Blacklist
Lost, stolen, or unpaid phones end up on international blacklists. You can verify the IMEI status using reliable free databases (such as imeipro.info or swappa.com/esn). A Clean status means the device is safe, while Blacklisted indicates the phone has been blocked.
3. Account Locks (iCloud / Google FRP)
Always verify that the previous owner has completely signed out of their Apple ID or Google account and perform a full factory reset in front of you. The activation screen should not prompt for someone else's credentials.
