Starting with 22.1.a release, FTC will switch to credits-based SMS accounting. All existing licensed customers will receive a total SMS credit equivalent to their existing SMS balance x 10.
Each time-based license (SKU) allows for 125 SMS credits for each end-user annually. The FTC Dashboard page displays your SMS credit balance.
The number of credits that FTC charges for SMS use varies, depending on where the end-user's phone number is registered. For more information, see SMS Rate Card.
