Regarding drivers

hello,

We are want to use RIOT in our application . Functionality of our application is getting data of our sensor and pushing that data to our server. So that we had decided to use riot OS.

Please can you guys guide me how to connect gsm sim in riot to connect internet access to push data and get push notification in the device from the server. How to make a voice call, internet acces, data to send server.

Thanks
