00018    APN stands for Access Point Name, a setting on your modem or phone
00019    that identifies an external network your phone can access for data
00020    (e.g. 3G or 4G Internet service on your phone).
00021 
00022    The APN settings can be forced when calling the join function.
00023    Below is a list of known APNs that us used if no apn config
00024    is forced. This list could be extended by other settings.
