Method 2: Getting an Unlock Code From Your Carrier

This is how to unlock a SIM card on an iPhone that is locked by the carrier. If you are not being able to use any SIM card on your iPhone except the one that you are using now, follow these steps:

1. Call your carrier’s Customer Support. You can try dialing *611 or 611, as these are the default customer support numbers on most phones.

  • AT&T Customer Service – 1 (800) 331-0500
  • T-Mobile Customer Service – 1 (800) 922-0204
  • Sprint Customer Service – 1 (888) 211-4727
  • Verizon Customer Service – 1 (877)-746-0909

Keep your carrier account PIN within reach. You will need that to verify your identity.

2. You will reach an automated assistant. Communicate and convey your problem. To get a real human to talk to, try saying something like, “I want to remove on SIM card.” This should get you connected to a customer service representative.

3. Ask the customer service representative for a PIN unlock code. Explain to them that you are only trying to unlock your SIM card, not the iPhone itself.

If you have put in the wrong PIN too many times, your unlock code will be a PUK code.

4. Note down your PIN unlock code. You will unlock your SIM with this 4-digit PIN.
