PORTAL

I would just be tempted to ring the number. I am one of those people who would touch a wall with a "Don't Touch" sign. Always rush in, where angels fear to tread. 🙂

Maybe you’re looking for the number for a relative you haven’t spoken to for a while, maybe you need to call your friend Pete, maybe there’s a leak and you need to call a plumber.
Whatever the reason, when you scroll through your contacts down to P, you’ll spot a new entry and you’ll pause and frown, as you don’t remember adding it.
It is just one name, Portal. If you click to enter it, you’ll see there are no details other than what looks like a phone number, but doesn’t look like any phone number you have seen as it’s far too long.

Delete it. Whatever you do, do not call this number. Despite being far too long to be a phone number, it will connect. But you’ll wish it hadn’t.
