+   APN stands for Access Point Name, a setting on your modem or phone
+   that identifies an external network your phone can access for data 
+   (e.g. 3G or 4G Internet service on your phone). 
+   
+   The APN settings can be forced when calling the join function.
+   Below is a list of known APNs that us used if no apn config 
+   is forced. This list could be extended by other settings.
+
