If your iPhone is provided by Globe when you apply for a plan and already finished the contract, you can call the hotline Contact Us to file a request for the unlocking of your device. The unlocking will take 5 business days to process, once it is already unlock you will either receive a call or sms confirming that your device is already unlock. Just make sure that when you file your request do not forget to get your reference number for the said request.
I found a great software to easily unlock your Iphone. Just install software, connect phone to computer. Run the wizard, and boom! You have a newly unlocked Iphone for your to enjoy.
