I've seen this intro before and here is what I think is happening.
Aiden connects to the network locally, and his hacker friend routes through him. It goes like this
Hacker -> Internet -> Aiden -> Network -> Victim(s)
Yes this is possible, all you'd need to a payload on the phone and port forwarding configured on the router. Once you execute the payload on the phone to stationary attacker could establish a route on the phone and pivot into the network.
In short, yes it's possible, but not very straight forward.#BringBackOTW-Defalt
If you are asking if you can crack wifi with your phone's wifi adapter: no.
If you are asking if you can give someone access remotely through your phone to the wifi network you are already connected to (like Aiden does here): yes. #BringBackOTW
