One can write their own implementation of SMS with preferable SMS providers and by exposing the API, it can be used in any of the Bahmni repositories for sending SMS.

sms-service is a reference implementation which uses D7 SMS service provider for sending SMS. If anyone wants to use different SMS service providers, then they can fork out sms-service repository and write their own implementation of the interfaces with the preferred service providers.
