SS7 is vulnerable to attack. However, the types off attacks on the video don't affect Signal as it requires a pin. (Make sure you set your pin to something strong and secure)

He says nothing about the PIN, so I don't think that is what protects Signal as OP writes. It simply doesn't rely on SS7.

You only type your PIN into Signal about once a month.
