2. RECIPIENT’S PHONE NUMBER SWITCHED OFF FOR LONG : 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 wouldn’t get the message.
3. RECIPIENT’S PHONE NUMBER OUT OF NETWORK COVERAGE : The same thing that happens in terms of delivery validity period as with when phone numbers are switched off also applies here. Once the phone number is not in a network enabled area for a long period of time, the message expires and it won’t get delivered.
