If you did not entered expenses from SMS at once but chose "Back" or "Close" buttons, and continued work in CoinKeeper, then you can enter purchases in CoinKeeper later. For this purpose, select the item “Distribute SMS” in the side Menu.

If you click on "Distribute SMS" but there are no coins with SMS on the main screen, then, most likely, you set up the SMS recognition option recently and meanwhile did not receive any messages about purchases or transfers with a bank card.
