Question:
In SMS, Can you tell me which are promotional prefixes and which of these are transactional?
Answer:
One can differentiate a transactional SMS from a promotional SMS based on the Sender ID it gets delivered from.
Transactional Sender ID | Promotional Sender ID |
 |  |
Both of them have prefixes (AM) which are automatically set by the operator delivering this particular message. Because we work with different SMS gateways who internally work with others & eventually operators who may try to send your SMS via the cheapest & best route possible, the prefix is unpredictable. These prefixes are meant to inform the recipient about the channel used in delivering the SMS. Typically, they use this information to report an NDNC violation.
The following are the list of SMS prefixes and their explanation:
