Before you send your first text message, MSP will prompt you for a "reply" number. This can be any number you choose.
To change this number for future text messages, or automatic text message reminders:
- Go to the Web Terminal pane in MSP and click the "Web Terminal settings..." button at the top.
- Click on "Auto Reminders" on the left, and in the lower set of options for the text reminders, the very last box will allow you to specify and change the "Send replies to" number.
