You can know if your iPhone is unlocked by checking its settings or using other methods as follows:
How to Check if Your iPhone is Unlocked
1. Check in iPhone Settings:
- Open the Settings app.
- Go to General > About.
- Scroll down to find Network Provider Lock or Carrier Lock.
- If it says No SIM restrictions , your iPhone is unlocked and can be used with any carrier.
- If it shows a carrier name or says SIM locked , then your iPhone is locked to that carrier
2. Test with a Different SIM Card:
- Insert a SIM card from a different carrier.
- If the iPhone connects to the new network without error, it is unlocked.
- If you get an error like "SIM Not Supported" or "Invalid SIM," the phone is locked
3. Use the IMEI Number:
- Find your IMEI by dialing *#06# or in Settings > General > About.
- Use an online IMEI checker to see the lock status.
- Note that many IMEI checkers charge a fee or may not be fully reliable, so use trusted services
4. Contact Your Carrier:
- Call your carrier’s customer service.
- Provide your iPhone’s IMEI number.
- They can confirm if your phone is locked or unlocked and help unlock it if eligible
Summary
The easiest and most direct way is to check Settings > General > About and look for “No SIM restrictions” under Network Provider Lock.
