Q: What's the best way to Unlock an iPhone 5?

It sounds like a second hand phone. If it is asking for an Apple ID, only the original owner can remove that. With the limited information you have given, I would return it for a refund and purchase a phone from a legitimate source.

I bought an iPhone 5, not knowing it was Locked and without a sim. I would like it just to work, I don't care if I cannot get service on it. Which method of unlocking is the best?

Like an icloud lock or a passcode lock?

First, your carrier will need to process your unlock request. Then you'll back up, erase, and restore your iPhone to unlock it.

Start the process:

1. See if your carrier offers unlocking. Only your carrier can unlock your iPhone.
2. Contact your carrier and request an unlock. You might need to meet requirements to qualify for unlocking. After you submit the request to your carrier, it might take a few days to complete. Contact your carrier for the status of your unlock request.
3. After your carrier confirms that your iPhone unlock has been processed, go to the next section.

If you have a SIM card from a carrier other than your current carrier, follow these steps:

1. Remove your SIM card and insert the new SIM card.
2. Complete the setup process.

If you don't have another SIM card you can use, follow these steps to complete the process:

1. Back up your iPhone.
2. When you have a backup, erase your iPhone.
3. Restore your iPhone from the backup you just made.
