How to check if your smartphone is unlocked

To check if your smartphone (whether Android or iPhone) is unlocked, you can use the following methods:

Method 1: Test with a SIM Card from Another Mobile Carrier

  1. Turn off your phone.
  2. Remove the current SIM card and insert a SIM card from a different carrier.
  3. Turn the phone back on and wait for it to load.
  4. Check for network connectivity:
    • If your phone connects to the new network and allows you to make calls, send texts, and use mobile data, it is unlocked.
    • If you get a message like "SIM Not Supported" or "Enter SIM Network Unlock PIN," your phone is locked to the original carrier.

Method 2: Check the Phone Settings (iPhone)

  1. Go to "Settings" on your iPhone.
  2. Tap on "General", then "About".
  3. Scroll down to "Carrier Lock":
    • If it says "No SIM restrictions," your phone is unlocked.
    • If it displays something else, your phone might be locked.

Method 3: Check the Phone Settings (Android)

  1. Go to "Settings" on your Android device.
  2. Navigate to "Connections" or "Mobile Networks" (this might vary depending on your device).
  3. Look for "Network Operators" or "SIM card status".
    • If your phone shows several available networks, it’s unlocked. If you can only select one, however, then it’s locked to that one.

Method 4: Contact Your Carrier

Contact the carrier that originally sold the phone. Provide them with your phone's IMEI number (found by dialing *#06# or in the device settings under "About Phone") and ask them to verify if the device is unlocked.

Method 5: Use an Online IMEI Checker

There are online services where you can input your phone’s IMEI number to check if it is unlocked. Make sure to use a reputable service to avoid scams.

Method 6: Look at Purchase Details

If you bought the phone outright from a retailer, directly from the manufacturer, or as an unlocked device, it’s most likely unlocked. Phones bought under a contract or instalment plan from a carrier may be locked.

Method 7: Insert a SIM Card and Look for a Prompt (iPhone Specific)

  1. Insert a new SIM card and restart the phone.
  2. If you get a prompt to activate the phone (and it proceeds without issue), your phone is unlocked. If it asks for an unlock code, it’s locked.

Method 8: Check for a Carrier Unlock Option (Android)

  1. Go to "Settings".
  2. Navigate to "About Phone" and then "Status" or "SIM Status".
    • If it says "Network Unlocked," the phone is unlocked.

Using these methods, you can determine if your smartphone is unlocked and ready for use with other carriers.
