Automated SMS Messages can be delayed to a certain hour of the day to prevent early morning SMS's being sent for system events (payment receipts, non-attendance alerts).  If a specific value is not set our system default value of 7.00am is applied.  Detailed below are steps to change this value to a time that is more suitable.

Go to Configuration -> System Setup -> SMS

Change 'Do not send before - Hour' to the hour of day that you require SMS's to begin sending.  Only the hour value is required - eg: 07 is 7.00am, 08 is 8.00am, 09 is 9.00am etc.

This setting is applied immediately.  If left blank, 07 (7.00am) is applied as the default value.
