how do i unlock my i phone 5

Hi

Follow the instructions here, as appropriate for your issue:

If your iPhone is locked to a different carrier than the one that you want to use:

• How to unlock your iPhone - Apple Support

If you have forgotten your passcode:

• If you forgot the passcode for your iPhone, iPad, or iPod touch, or your device is disabled - Apple Support

If your iPhone is locked with Activation Lock:

• Turn off Find My iPhone Activation Lock - Apple Support

If your Apple ID is locked:

• If your Apple ID is locked or disabled - Apple Support

ONLY the carrier to which it is locked can unlock it.

Contact that carrier and see if they offer this service and if you qualify
