My iPhone is lock

This is a risk you take buying a used iPhone. Activation Lock can ONLY be removed by the user who owned the phone and put it there. Apple will NOT help you. We CANNOT help you. Unless you know and can get the help from the owner whose ID the phone is locked to, you have a totally useless device. There is no help.

Bottom Line: Either return the phone for refund or recycle it.

The only way to use it is to get the person who entered the Apple ID and password to remove it. I am guessing that you do not know that person. If that is the case, you will never be able to use that phone. Your only option is to return it for a possible refund.

Hi there,

It sounds like you purchased an iCloud locked iPhone. The only way to unlock it is the original Apple ID used when it was first set up, with hardly any exceptions. If you have information on where you purchased the phone, you could get help on how to get a refund. I'm sorry you didn't get lucky with it, and unfortunately we can't help you with that.

Sorry. The phone is totally useless. If you can't get your money back, recycle it as it cannot be used by you ever.

Activation Lock is a theft deterrent feature. What this means is that you probably bought a stolen phone. There isn’t anything you can do about it. Note that some Android phones have a similar feature, so be very careful when buying any used phone and only buy from someone you trust.

Then the seller, if they are honest, needs to remove Activation Lock on the phone.

It is NOT Apple's fault you bought a used iPhone which is Activation Locked. Sorry, but you should have done some research before you parted with your money and learned what to look for in a used device. Apple takes our security VERY seriously and they will not unlock an iPhone for ANYONE other than the original buyer and ONLY then with proof of original purchase.

It's unfortunate you were scammed, but it's most definitely not Apple's fault someone took advantage of you.

All you know is that it wasn’t reported stolen to the police in Iran. Not all stolen phones are reported stolen, and if it was stolen in a different country the local police would not know about it even if it was reported stolen in another country. Indeed, it is common for thieves to ship the phone to a different country to avoid it being identified as stolen. What country did it originally come from? not Iran, because Apple is not permitted to do business in Iran. The model number has information to identify the country of origin.

The seller ripped you off, if you can't find them, or you did and they won't give you your money back, report them to the police. They stole from you.

What is the model number?
