Expired message (SMS)

When we send an SMS campaign, the messages go out and, in case they cannot be delivered instantly, they are reattempted during the following 48 hours. If the recipient's mobile phone is inaccessible, either because it is switched off or because there is no coverage, the operator will not be able to deliver the SMS to the recipient. This will cause the SMS to expire and, therefore, the message cannot be delivered in any way.
