Seems you would need to use a cellular service provider, or wi-fi / internet service to make calls.
If you have no cellular service for your iPhone for making calls:
yet
if you do have an internet connection, you may be able to make audio (or video) calls over wi-fi using FaceTime (audio calls are not available in all countries)
First : Check you are signed in (to your iPhone) with your Apple ID:

Then: To get started with FaceTime, go to Settings 
>
FaceTime,
then turn on FaceTime.
Below “You can be reached by FaceTime at,”
enter your Apple ID or phone number, if you haven’t already.
