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.
