Simple answer
Is Menace Mobile a real phone company?
No — Menace Mobile is best understood as a fictional mobile network used for the Dr Evil advert. The name, pricing maze and plan titles are part of the joke. They make the network feel deliberately over-complicated, which suits the Dr Evil character.
That is why people are searching for it. The advert makes Menace Mobile look like a real brand for a moment, but the whole point is parody. It takes something familiar — mobile phone plans — and turns it into a villain-style maze.
