usage of "call away"

when we say “your potential partner is just a call away”.what does “call away” literally mean here and how to interpret it.please explain.

Have a look:
I’m trying to make out one of my favourite songs from Soul Asylum.
“You’re a dream for insomniacs, prize in the cracker jacks
All the difference in the world is just a call away”
The meaning is:
All that stands between you and all the difference in the world is a call.
Meaning: if she/he calls you, that will make all the difference.

  • I hope that helps.

I’m assuming that this is a slogan for a dating agency.

“call” means “telephone call”.

“Your potential partner is just a call away” claims that you may be able to find a (romantic) partner just by making one telephone call.

thanks awfully for the efficient answer and please also tell me that when we say “i am not stupid”.in place of stupid can we say “i am not dumb”.here actually i mean to say “i am not unintelligent”.explain the difference.

You can say ‘I am not dumb’ . There’s no difference other than the fact that ‘dumb’ is less formal despite the contention that there is in some older threads on this forum.
The pronoun ‘I’ is always written as a capital letter.
Sentences always begin with a capital letter.
