Yes. Order a number in the country you test, trigger your app's code and read the SMS on your order page.

Use a rental number. It stays yours from 1 day to 30 days and receives every code your app sends in that time.
What if the test code never arrives?
You pay nothing. The order closes after 20 minutes and the money returns to your balance.
Is my app in the service list?
The app lists 1,300+ services. If yours is not there, write to support@privasto.com before your test run.
