icloud lock But Now How can unlock my Phone

It's a really bad idea to post your phone number - it's an invitation to nuisance calls - and I've asked the Hosts to remove it.

Does your screen look something like this (with the ID hint being not yours)? -

Did you buy the device second-hand (used)? If a used iOS device has been 'Activation locked' then only the previous owner can unlock it, either by providing you with the account ID and password, or by removing it from his list of devices (as he should have done before selling it).

If you are unable to contact him to do this then I'm afraid you will not be able to use the device - there is no other way of unlocking it at all. Apple cannot unlock it for you, nor find the previous owner for you, and neither can the websites that offer to unlock it for a fee: these are scams.

You should if possible return it to wherever you bought it and ask for a refund as in this event the device is completely useless.

If on the other hand you bought it new, and the ID it's asking for is yours but you've forgotten it, go to https://iforgot.apple.com to retrieve the ID and reset the password. See also If you forgot your Apple ID - Apple Support

Failing that, take the device, the original purchase documents, and some ID to an actual Apple Store (make an appointment) and ask if they can unlock it.

You didn't read my post, did you.

Short version: if you bought it used, you can't. If you bought it new, see the bottom two paragraphs of my post above.
