List of reasons why your SMS is not getting delivered

There are numerous reasons, why your SMS is not getting delivered. The reasons are:

1. Number not valid– Whenever you are sending SMS make sure that the number in which you are sending SMS is a valid number. Otherwise the message will not get sent.

So to avoid this problem, check the number after typing the message and make sure that the number is in use and valid.

2. Number not in network – Sometimes due to network connectivity issues the message is not sent immediately. But don’t worry as soon as the network issue is sorted out, the message goes straight away in the inbox of the receiver. So just wait for the network problem to get resolved. It will be categorized as ‘sent’. And as soon as the person  is in the network reach, it gets delivered automatically. If within the time frame of 12 hours it is sent then it is shown as delivered. Otherwise failed.

3. Promotional SMS (sending after 9 PM or before 9 AM) – It may happen that your message is not getting delivered because you are sending SMS in the wrong timings. The fixed time for sending promotional  SMS  to non DND numbers is after 9 AM and before 9 PM.

Note that if you are sending SMS after 9 pm, it will be automatically scheduled for the next day.

4. DND number (using promotional route) – The promotional SMS is only sent to non DND number. If you are sending promotional SMS to DND number then it will be rejected.

You can send SMS to DND number using the quick transactional route.This is a unique and useful feature introduced by Fast2SMS. The main benefit of using the quick transaction route is that you don’t need to get document verification and approval, which is required in the transactional route. Just get the message approved by Fast2SMS team and you can then send the message to DND number also.

5. Operator down – This happens in rare case. It might be possible that our operator is down that is why the SMS is not getting delivered. But you don’t need to worry as it happens very occasionally and is not usual. If by chance it happens, as soon as the operator’s problem gets resolved, the SMS will be sent therein.
