There were no errors in the delivery logs. Not sure if there are any errors @ mid-sourcing for delv: DM302747.
As you suspected, the default typology rule:Message size validation is possibly restricting the delivery. As, I received a SMS after removing this rule from the typology. However, I have few further queries in this regard:
1. What could be the possible implications of removing this rule? Is it required to modify the default code used in it?
2. I received single message for this SMS instead of two. Like to understand the expected behaviour in such cases.
3. The status of Delivery and Delivery Logs were "Being Edited" and "Pending" respectively after 2 hours of receiving this message. Would like to discuss it as well.
