How do you unblock boyfriends phone?

To unblock your boyfriend's phone, you first need to ensure you have permission to do so. If you have access, you can go to the phone's settings, find the blocked contacts section, and remove his number from the list. If it's a matter of unlocking the device itself, you may need to enter the correct passcode or use biometric features like fingerprint or facial recognition. Always communicate openly with your partner about privacy and trust when addressing such issues.
