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.
Upon termination of your month to month membership, accumulated member service packages expire and are non-refundable 90 days after you cancel your membership, accumulated member services expire 90 days after the last day of a Prepaid Term Membership.
