Q: how do i use my IME number to unlock iphone given by friend in the USA

IMEI has not much to do with SIM unlock

If your friend bought a phone which is locked to a carrier - you have to contact the carrier

How to unlock your iPhone for use with another carrier - Apple Support

Hi

The IME number has nothing to do with a locked iPhone .

If iphone his still locked to your friends apple ID ask him to go to find my iPhone on an apple device he owns

Top left hand corner device list remove iPhone he gave you from the list .

Then you need to restore iphone back to factory settings & set up with your apple ID .

Cheers

Brian

Just to be clear, it isn't clear if you mean a SIM lock that locks the phone to a carrier, or Activation Lock, which locks it to an Apple ID and is a theft deterrent. So you got answers to both types of lock.
