-* Install your sim card in your module, connect the GSM antenna and mount the module on the pin headers of your Raspberry Pi
-  Make sure, that you **do not** need to enter Pin Code to use your card

-* Outgoing and Incoming Calls
-* GPS functionality
 * More options to configure the module (e.g. using sim cards with pin code)
