How to unlock SIM card for iPhone

Hello tinsae130!

If you forgot or don't know your SIM PIN

Never try to guess a SIM PIN or PUK code.* The wrong guess can permanently lock your SIM card, and then you would need a new SIM card. If your device asks for a PIN or code that you don't know, here's what to do:

1. Contact the carrier that gave you the SIM card. If you aren't sure which carrier to call, remove the SIM card and check the card for the carrier's name or logo.
2. 
3. Ask your carrier to help you unlock your SIM card using the default SIM PIN or PUK code. 
4. If you can't unlock your SIM card using the SIM PIN or PUK code or if an alert says, "PUK exhausted," ask for a new SIM card.

*If you enter the wrong SIM PIN too many times, your wireless carrier might be able to give you a Personal Unlocking Key (PUK).

I hope this is helpful. Good Luck!

You cannot unlock the SIM card.......only the carrier who locked the SIM can do this. Contact them and ask them to release the lock on the phone.

Depending on the original agreement with the carrier, they may be under no obligation to do this.

It does not matter where you are located. The question has already been answered in my previous response.
