Reason #7 for Bulk SMS Delivery Failure- 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. In order for text messages to move from the sender and get delivered to the chosen destination, the receiver must have the network available on his/her phone. 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.
In order for you to know the delivery status of your sent messages and also to understand why your sent messages did not get delivered in cases when they don’t, at SmartSMSSolutions, there is an ability to check delivery report for your sent messages. Also, we’ve put together the different delivery status codes and what they stand for .
It is our abiding interest here at SmartSMSSolutions to get your sent messages delivered and the system down here is optimized to do just that provided the above factors are effectively handled.
