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.
|
