When will I receive a message about an activity happening within / in my account?

Instantly! You’ll receive instant SMS notifications after each transaction you make, so you always know what has been spent, where, and when. You don’t need to wait a few days to see a transaction, or until the end of a billing period to see all your transactions. For your convenience, you can always visit the “Transactions” section in the app to have a comprehensive overview of all your transactions at any time.
