Q) How do we change the conversation window for a text response for a Short Code?
A) Conversation window is the amount of time a subscriber has to respond to a sms message before it is registered to the default keyword. The default window is 60 minutes.

For example: On a double opt-in, if a subscriber texts the Join keyword they have 60 minutes to text in Y for the double opt-in to process, otherwise they subscriber will need to start the opt-in process over. Most uses cases this should be no larger than 3-4 hours due to causing conflicts with other SMS engagement to the subscriber. If you would like to update the conversation window please review the following documentation.

Q) How do we move a Short Code or Long Code from Marketing Cloud to another vendor?
A) Contact your Account Representative to assist with the code migration. A support case will be needed for a code migration to occur.

Q) Why was an SMS sent from a different Long Code/ Short Code than the one specified in the send request? 
A) This occurs when the specified Long Code/ Short Code is not enabled for the target country (market). The system automatically searches for and uses any other existing, enabled Long Code in the account for that market to complete the send. This does not gurantee the sms delivery. 

Q) How can message send codes be aligned with the intended market?  
A) Sending entities must use a Long Code/short code that is explicitly configured and enabled for the specific market of the recipient.
