While this is purely dependent on you or your customers, we do have some restrictions in place to limit the amount of airtime you can send.

We are not in control of these restrictions; they do come from the telcos.

To know which amounts are supported for sending airtime, you can view them on our docs here https://developers.africastalking.com/docs/airtime/overview

Navigate to Airtime -> Sending then scroll to the bottom, there is a section called Request Limits. This will show you the acceptable amounts and the currency codes to use in your app
