I just noticed my phone has been connected to number "0" for over an hour. I am guessing I leant on the phone (I found it on my bed) and it dialed this number accidently. The time connected was just over an hour. When I found the phone I couldn't hear anything at the other end. Who is actually at number "0" if dialled or is it no-one and no company ? I not sure if there is such a thing as a 1 number phone number, but I am just confused how it seemed to be connected (as in the phone was counting up in minutes).

So should I rush to check my bill or does nothing exist at just a 1 number dialed call ?

Cheers.

There can be no number that connects just as "0", since "0" is the starting number for all non-local numbers it cannot route.
