You can download the NOC letter template from downloads section. Operators have blocked all the generic sender names and any SMS that needs to be terminated to KSA should have a valid Sender ID related to the company.
Messages template (samples) are provided to the operator in advance to make sure there is no misuse of the sender names or the SMS services. It is advised not to deviate much from the template shared or chances of the sender getting blocked are high.
For Marketing Messages, all the sender name should be appended with "-AD", thus leaving the total sender name length to 8 characters. Any marketing message send without "-AD" in the sender name will be considered as a violation and can lead to blocking of the sender name.
On the other hand, P2P or Person to Person (Peer to Peer) are all messages that are sent from one mobile phone to the other directly. These messages are initiated by humans and send manually.
For certain operators, there will be a prior registration / white listing that is required with certain documents like NOC, Trade License, Message samples etc. Once the details are submitted registration can take anywhere between 1 to 5 working days.
