I have an SMS Gateway integrated with Adobe Campaign. The problem is it can only send SMS messages with the country code in front of the number, but most of our customer data does not contain the country code. We are in Australia (Country code +61) but mobile numbers start in 04. Thus, most of the mobile numbers in our database are stored as "04xx xxx xxx" when they need to be "614xx xxx xxx". Is there any way in a workflow or the data loading/update data function to change all entries that start with 04 to start with 614?
