Whenever I see an "easy to remember" phone number (e.g. on a prepaid SIM card for sale, or otherwise), I get excited (non-sexually). I fantasize about using the number to call all sorts of "important" people, and I think these numbers make their owners a part of the "VIP club". If someone has such a number, I tend to think they must be successful and popular. I'm talking about numbers like 517-0000 or 233-2233.
