In the app, you can subscribe to a number or calling plan with prices varying depending on the chosen nationality or region, as well as the duration (1, 3, or 12 months). Payment will be made through your iTunes account after purchase confirmation and will be withdrawn 24 hours before the end of each billing cycle.
