Connect playSMS to MNO's SMSCs

I am new to playSMS and i would like to know whether playSMS can connect directly to MNO’s SMSCs with Kannel or GAMMU?


By using what protocol did you mean by directly connect ?

I know only SMPP or REST/HTTP API


I meant HTTP.

Most importantly, can playSMS support USSD?

Many thanks

HTTP depends on the API, most likely you have to build your own plugin

playSMS does not support USSD


Thanks for the response
