String literal. A string literal or anonymous string is a type of literal in programming for the representation of a string value within the source code of a computer program.
As usual, the devil is in the details. For instance, with some prepaid wireless plans, your minutes are only good for a limited time, usually 30 to 90 days. If you don't use them before they expire, they are simply subtracted from your account anyway.
So until the person refills their minutes they are unreachable by that number..... 2. 0. If the person you are trying to call has a prepaid phone all it means it that they are out of minutes. So until the person refills their minutes they are unreachable by that number.
