Reason 3 for Failed Delivery of Bulk SMS- Recipient’s Phone Number has Been Switched off for Long
Network operators have a message delivery validity period, a time period during which a message can stay viable before expiration. When an SMS gets to a phone number and the phone number is switched off at that moment, there is validity time period the message can stay that way waiting for the phone to come back on so to speak. If the phone remains that way for long and the waiting period elapse, the message expires and whenever the phone does comes back on, the owner won’t get the message.
