I assume you want to unlock your device rather than your pac code, which is used to move networks?
To unlock your device then please see EE guide on how to proceed.

You only need a PAC code when moving your number to another network.
Providing the iPhone 7 is network unlocked, your grandson will be able to use it on his chosen network.
If you do need a PAC code, you can get your PAC code by calling customer service on 150.
They will give you the PAC code over the phone and also in a text too. The text will show you when the PAC code expires (PAC codes are valid for 30 days).
